Abstract
Distal femur fractures (DFFs) are common injuries with significant morbidity. Surgical options include open reduction and internal fixation (ORIF) with plates and/or intramedullary devices or a distal femur endoprosthesis (distal femur replacement [DFR]). A paucity of studies exist that compare the two modalities. The present study utilized a 1:2 propensity score match to compare 30-day outcomes of geriatric patients with DFFs who underwent an ORIF or DFR. The National Surgical Quality Improvement Program data from 2008 to 2019 were utilized to identify all patients who sustained a DFF and underwent either ORIF or DFR. This yielded 3,197 patients who underwent an ORIF versus 121 patients who underwent a DFR. A final sample of 363 patients (242 patients with ORIF vs. 121 with DFR) was obtained after a 1:2 propensity score match. Costs were obtained from the National Inpatient Sample database using multiple regression analysis and validated with a 7:3 train-test algorithm. Independent samples t-tests and chi-square analysis were conducted to assess cost and outcome differences, respectively. Patients who received a DFR had higher transfusion rates than ORIF (p = 0.021) and higher mean inpatient hospital costs (p = 0.001). Subgroup analysis for patients 80 years of age or older revealed higher 30-day unplanned readmission (0 vs. 18.2%; p < 0.001) and 30-day mortality (0 vs. 18.2%; p < 0.001) rates for patients undergoing ORIF compared with DFR. The total number of DFR cases needed to prevent one ORIF-related 30-day mortality for DFR for patients 80 years of age was 6 (95% confidence interval: 3.02-19.9). The mean hospital costs associated with preventing one case of death within 30 days from operation by undergoing DFR compared with ORIF was $176,021.39. Our results demonstrate higher rates of transfusion and increased inpatient costs among the DFR cohort compared with ORIF. However, we demonstrate lower rates of mortality for patients 80 years and older who underwent DFR versus ORIF. Future studies randomized controlled trials are necessary to validate the results of this study.

Impact of surgical timing and type of operative procedure on outcomes in periprosthetic hip fractures: an observational study at an NHS trust centre in the UK. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:2099-2105. [PMID: 38551739 DOI: 10.1007/s00590-024-03900-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Accepted: 03/06/2024] [Indexed: 05/19/2024]
Abstract
PURPOSE There is a global trend of increased periprosthetic fractures due to the growing number of arthroplasty procedures. The present study assessed the impact of factors such as time to surgery and type of surgery on the outcomes, which have been seldom evaluated for periprosthetic fractures. METHODS An observational study was conducted on consecutive 87 patients within an NHS district hospital trust in the UK. Patients who underwent a complete hip replacement prior to the fracture, received fixation therapy, or underwent revision surgery within the specified time were screened. Patients were grouped in two ways: based on time to surgery and based on surgery type. Logistic regression models were performed to assess for statistically significant differences in post-operative complication, 30-day, and 1-year mortality rates between groups, whilst adjusting for age, gender, and ASA grade. RESULTS Forty-one patients underwent open reduction and internal fixation (ORIF), 29 patients underwent revision arthroplasty, and 17 patients were subjected to both, ORIF and revision arthroplasty. Sixty of the 87 patients were operated on > 48 h of injury. The median hospital stay was significantly lower in the ORIF plus revision arthroplasty group, versus other surgical groups (p < 0.05) whilst it was significantly higher in the group of patients who underwent surgery after 48 h of injury (p < 0.05). Numerically higher mortality was noted in the revision arthroplasty group (31.03%, p > 0.05). The group that was operated after 48 h of injury showed greater mortality but was comparable to the other group (25% vs. 14.81%, p > 0.05). For post-operative complications, none of the variables were significantly predictive (p > 0.05). However, for 30-day mortality, ASA grade (p = 0.04) and intra-operative complications (p = 0.0001) were significantly predictive. Additionally, for 1-year mortality, ASA grade (p = 0.004) was noted to be significantly predictive. CONCLUSION Revision and delayed periprosthetic fracture management (> 48 h after injury) group showed a numerically greater mortality risk; however, this finding was not statistically significant. ASA grading at baseline is predictive of mortality for periprosthetic fractures.

Operative treatment of fragility fractures of the pelvis is connected with lower mortality. A single institution experience. PLoS One 2021; 16:e0253408. [PMID: 34242230 PMCID: PMC8270175 DOI: 10.1371/journal.pone.0253408] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 06/05/2021] [Indexed: 11/27/2022] Open
Abstract
Background Fragility fractures of the pelvis (FFP) represent an increasing clinical entity. Until today, there are no guidelines for treatment of FFP. In our center, recommendation for operative treatment was given to all patients, who suffered an FFP type III and IV and to patients with an FFP type IIwith unsuccessful non-operative treatment. We performed a retrospective observational study and investigated differences between fracture classes and management alternatives. We hypothetized that operative treatment may reduce mortality. Materials and methods The medical charts and radiographs of 362 patients were analysed. Patient demographics, FFP-classification, length of hospital stay (LoS), type of treatment, general and surgery-related complications, mortality, Short Form-8 physical component score (SF-8 PCS) and mental component score (SF-8 MCS), Parker Mobility Score (PMS) and Numeric Rating Scale (NRS) were documented. Results 238 patients had FFP type II and 124 FFP type III and IV. 52 patients with FFP type II (21.8%) and 86 patients with FFP type III and IV (69.4%) were treated operatively (p<0.001). Overall mortality did not differ between the fracture classes (p = 0.127) but was significantly lower in the operative group (p<0.001). Median LoS was significantly higher in FFP type III and IV (p<0.001) and in operated patients (p<0.001). There were more in-hospital complications in patients with FFP type III and IV (p = 0.001) and in the operative group (p = 0.006). More patients of the non-operative group were mobile (p<0.001) and independent (p<0.001) at discharge. Half of the patients could not return in their living environment.203 of the 235 surviving patients (86%) answered the questionnaires after a mean follow-up time of 38 months. SF-8 PCS, SF-8 MCS and PMS did not differ between the fracture classes and treatment groups. Pain perception was higher in the operated group (p = 0.013). Conclusion In our study, we observed that operative treatment of FFP provides low mortality rates, although LoS and in-hospital complications were higher in the operative group. At discharge, the non-operative group was more mobile and independent. At follow up, quality of life and mobility were comparable between the groups. Further prospective studies are needed to clarify the impact of operative treatment of FFP on mortality and functional outcome.

Abstract
BACKGROUND Hip fractures are a major healthcare problem, presenting a huge challenge and burden to patients, healthcare systems and society. The increased proportion of older adults in the world population means that the absolute number of hip fractures is rising rapidly across the globe. The majority of hip fractures are treated surgically. This review evaluates evidence for types of internal fixation implants used in joint-preserving surgery for intracapsular hip fractures. OBJECTIVES To determine the relative effects (benefits and harms) of different implants for the internal fixation of intracapsular hip fractures in older adults. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Web of Science, Cochrane Database of Systematic Reviews, Epistemonikos, Proquest Dissertations and Theses, and National Technical Information Service in July 2020. We also searched clinical trials databases, conference proceedings, reference lists of retrieved articles and conducted backward-citation searches. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs comparing implants used for internal fixation of fragility intracapsular proximal femoral fractures in older adults. Types of implants were smooth pins (these include pins with fold-out hooks), screws, or fixed angle plates. We excluded studies in which all or most fractures were caused by specific pathologies other than osteoporosis or were the result of a high energy trauma. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion. One review author extracted data and assessed risk of bias which was checked by a second review author. We collected data for seven outcomes: activities of daily living (ADL), delirium, functional status, health-related quality of life (HRQoL), mobility, mortality (reported within four months of surgery as early mortality, and at 12 months since surgery), and unplanned return to theatre for treating a complication resulting directly or indirectly from the primary procedure (such as deep infection or non-union). We assessed the certainty of the evidence for these outcomes using GRADE. MAIN RESULTS We included 38 studies (32 RCTs, six quasi-RCTs) with 8585 participants with 8590 intracapsular fractures. The mean ages of participants in the studies ranged from 60 to 84 years; 73% were women, and 38% of fractures were undisplaced. We report here the findings of the four main comparisons, which were between different categories of implants. We downgraded the certainty of the outcomes for imprecision (when data were available from insufficient numbers of participants or the confidence interval (CI) was wide), study limitations (e.g. high or unclear risks of bias), and inconsistency (when we noted substantial levels of statistical heterogeneity). Smooth pins versus fixed angle plate (four studies, 1313 participants) We found very low-certainty evidence of little or no difference between the two implant types in independent mobility with no more than one walking stick (1 study, 112 participants), early mortality (1 study, 383 participants), mortality at 12 months (2 studies, 661 participants), and unplanned return to theatre (3 studies, 736 participants). No studies reported on ADL, delirium, functional status, or HRQoL. Screws versus fixed angle plates (11 studies, 2471 participants) We found low-certainty evidence of no clinically important differences between the two implant types in functional status using WOMAC (MD -3.18, 95% CI -6.35 to -0.01; 2 studies, 498 participants; range of scores from 0 to 96, lower values indicate better function), and HRQoL using EQ-5D (MD 0.03, 95% CI 0.00 to 0.06; 2 studies, 521 participants; range -0.654 (worst), 0 (dead), 1 (best)). We also found low-certainty evidence showing little or no difference between the two implant types in mortality at 12 months (RR 1.04, 95% CI 0.83 to 1.31; 7 studies, 1690 participants), and unplanned return to theatre (RR 1.10, 95% CI 0.95 to 1.26; 11 studies, 2321 participants). We found very low-certainty evidence of little or no difference between the two implant types in independent mobility (1 study, 70 participants), and early mortality (3 studies, 467 participants). No studies reported on ADL or delirium. Screws versus smooth pins (seven studies, 1119 participants) We found low-certainty evidence of no or little difference between the two implant types in mortality at 12 months (RR 1.07, 95% CI 0.85 to 1.35; 6 studies, 1005 participants; low-certainty evidence). We found very low-certainty evidence of little or no difference between the two implant types in early mortality (3 studies, 584 participants) and unplanned return to theatre (5 studies, 862 participants). No studies reported on ADL, delirium, functional status, HRQoL, or mobility. Screws or smooth pins versus fixed angle plates (15 studies, 3784 participants) In this comparison, we combined data from the first two comparison groups. We found low-certainty evidence of no or little difference between the two groups of implants in mortality at 12 months (RR 1.04, 95% CI.083 to 1.31; 7 studies, 1690 participants) and unplanned return to theatre (RR 1.02, 95% CI 0.88 to 1.18; 14 studies, 3057 participants). We found very low-certainty evidence of little or no difference between the two groups of implants in independent mobility (2 studies, 182 participants), and early mortality (4 studies, 850 participants). We found no additional evidence to support the findings for functional status or HRQoL as reported in 'Screws versus fixed angle plates'. No studies reported ADL or delirium. AUTHORS' CONCLUSIONS There is low-certainty evidence that there may be little or no difference between screws and fixed angle plates in functional status, HRQoL, mortality at 12 months, or unplanned return to theatre; and between screws and pins in mortality at 12 months. The limited and very low-certainty evidence for the outcomes for which data were available for the smooth pins versus fixed angle plates comparison, as well as the other outcomes for which data were available for the screws and fixed angle plates, and screws and pins comparisons means we have very little confidence in the estimates of effect for these outcomes. Additional RCTs would increase the certainty of the evidence. We encourage such studies to report outcomes consistent with the core outcome set for hip fracture, including long-term quality of life indicators such as ADL and mobility.

Abstract
IMPORTANCE The outcomes of surgical treatment in patients with intertrochanteric hip fractures are unsatisfactory. Computer-assisted virtual preoperative planning may provide an opportunity to solve this treatment dilemma. Virtual preoperative planning is a technique based on dynamic 3-dimensional computed tomographic imaging, which allows precise evaluation of fracture details and simulation of reduction of fracture and internal fixation procedures before surgery is performed. OBJECTIVE To evaluate the association of computer-assisted virtual preoperative planning with the risk of 90-day all-cause mortality and postoperative complications. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study was conducted from using patient data from a level 1 trauma center database. A total of 1445 patients 65 years and older with intertrochanteric hip fractures between January 1, 2009, and March 31, 2018, were identified and divided into 2 cohorts: 558 patients received computer-assisted virtual preoperative planning (virtual planning group), and 887 patients received conventional preoperative planning (conventional planning group). Of the initial 1445 patients, 224 patients (93 patients in the virtual planning group and 131 patients in the conventional planning group) were excluded, resulting in 1221 patients in the final cohort. Data were analyzed from April 5 to October 5, 2019. EXPOSURES Computer-assisted virtual vs conventional surgical preoperative planning. MAIN OUTCOMES AND MEASURES Primary outcomes were 90-day all-cause mortality and postoperative complications (including myocardial infarction, heart failure, stroke, kidney failure, and sepsis). Secondary outcomes were 90-day outpatient visits, hospital readmissions, and reoperations. RESULTS Among 1221 patients who underwent hip surgery, the mean (SD) age was 73.2 (12.3) years, and 927 patients (75.9%) were women. A total of 465 patients (38.1%) were in the virtual planning group and 756 patients (61.9%) were in the conventional planning group. Among the 814 patients (407 patients in each group) who were matched by propensity score, the virtual planning group had a lower incidence of mortality (37 patients [9.1%] vs 55 patients [13.5%]; hazard ratio [HR], 0.64; 95% CI, 0.41-0.99; P = .04) and postoperative complications (25 patients [6.1%] vs 44 patients [10.8%]; HR, 0.54; 95% CI, 0.32-0.90; P = .02) compared with the conventional planning group. The incidence of outpatient visits was not substantially different in the virtual planning group (1.51 incidents per 30 person-days) compared with the conventional planning group (1.48 incidents per 30 person-days; incidence rate ratio [IRR], 0.90; 95% CI, 0.49-1.68; P = .75). Similar results were observed for the rate of hospital readmissions (0.99 incidents per 30 person-days in the virtual planning group and 1.01 incidents per 30 person-days in the conventional planning group; IRR, 0.91; 95% CI, 0.49-1.67; P = .76). However, the rate of reoperations was lower in the virtual planning group (0.76 incidents per 30 person-days) than in the conventional planning group (0.97 incidents per 30 person-days; IRR, 0.41; 95% CI, 0.22-0.76; P = .01). CONCLUSIONS AND RELEVANCE Among older patients with intertrochanteric hip fractures, computer-assisted virtual preoperative planning was associated with decreases in the risks of all-cause 90-day mortality, postoperative complications, and reoperations compared with conventional preoperative planning.

The Cost-Effectiveness of Reverse Total Shoulder Arthroplasty Versus Open Reduction Internal Fixation for Proximal Humerus Fractures in the Elderly. THE IOWA ORTHOPAEDIC JOURNAL 2020; 40:20-29.

Abstract
BACKGROUND Open reduction and internal fixation (ORIF) of proximal humerus fractures in elderly individuals (age >70) carries a relatively high short-term complication and reoperation rate but is generally durable once healed. Reverse total shoulder arthroplasty (RTSA) for fractures may be associated with superior short-term quality of life but carries the lifelong liabilities of joint replacement. The tradeoff between short and long-term risks, coupled with disparities in quality of life and cost, makes this clinical decision amenable to cost-effectiveness analysis. METHODS A Markov state-transition model was constructed with a base case of a 75 year-old patient. Reoperation rates, quality of life values, mortality rates, and costs were based upon published literature. The model was run until all patients had died to simulate the accumulated costs and benefits. RESULTS RTSA was associated with greater quality of life (7.11 QALYs) than ORIF (6.22 QALYs). RTSA was cost-effective with an incremental cost-effectiveness ratio of $3,945/QALY and $27,299/ QALY from payor and hospital perspectives, respectively. RTSA was favored and cost-effective at any age above 65 and any Charlson Score. The model was sensitive to the utility of both procedures. CONCLUSION RTSA resulted in a higher quality of life and was cost-effective in comparison to ORIF for elderly patients.Level of Evidence: III.

Comorbidity as the dominant predictor of mortality after hip fracture surgeries. Osteoporos Int 2019; 30:2477-2483. [PMID: 31451838 DOI: 10.1007/s00198-019-05139-8] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Accepted: 08/16/2019] [Indexed: 10/26/2022]
Abstract
UNLABELLED The aim of this study was to investigate the association of surgical delay and comorbidities with the risk of mortality after hip fracture surgeries. We found that CCI was the dominant factor in predicting both short- and long-term mortality, and its effect is vital in the prognostication of survivorship. INTRODUCTION Hip fracture is a growing concern and a delay in surgery is often associated with a poorer outcome. We hypothesized that a higher Charlson Comorbidity Index (CCI) portends greater risk of mortality than a delay in surgery. Our aim was to investigate the associations of surgical delay and CCI with risk of mortality and to determine the dominant predictor. METHODS This retrospective study examines hip fracture data from a large tertiary hospital in Singapore over the period January 2013 through December 2015. Data collected included age, gender, CCI, delay of surgery, fracture patterns, and the American Society of Anaesthesiologist (ASA) score. Post-operative outcomes analyzed included mortality at inpatient, at 30 and 90 days, and at 2 years. RESULTS A total of 1004 patients with hip fractures were included in this study. Study mortality rates were 1.1% (n = 11) during in-hospital admission, 1.8% (n = 18) at 30 days, 2.7% (n = 27) at 90 days, and 13.3% (n = 129) at 2 years. Lost to follow-up rate at 2 years was 3.3%. We found that CCI was consistently the dominant factor in predicting both short- and long-term mortality. A CCI score of 5 was identified as the inflection point above which comorbidity at baseline presented a greater risk of mortality than a delay in surgery. CONCLUSION Our analysis showed that CCI is the dominant predictor of both short- and long-term mortality compared with delay in surgery. The effect of CCI is vital in the prognostication of mortality in patients surgically treated for hip fractures.

Cephalomedullary nailing versus sliding hip screws for Intertrochanteric and basicervical hip fractures: a propensity-matched study of short-term outcomes in over 17,000 patients. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2019; 30:243-250.

Abstract
BACKGROUND Hip fractures are associated with poor mortality and morbidity outcomes. Controversy exists over what the preferred treatment is between sliding hips screws (SHSs) and cephalomedullary nails (CMNs) for stable intertrochanteric (IT) and basicervical (BC) hip fractures. The purpose of this study was to compare early postoperative outcomes and complications in patients treated with SHS to those treated with CMN in IT and BC hip fractures. METHODS We used the National Surgical Quality Improvement Program database to identify IT and BC hip fractures, excluding subtrochanteric hip fractures treated with a SHS and CMN for 2008 to 2016. After propensity score matching, there were 8505 patients in the SHS cohort and 8505 in the CMN cohort. Propensity score-adjusted multivariate regression models assed SHS as an independent risk factor for the following 30-day outcomes: mortality, postoperative major and minor complications, discharge disposition, readmission and reoperation, length of hospital stay (LOS), and operative time. RESULTS No difference in mortality was encountered between SHS and CMN (p = 0.440). Compared to CMN, the SHS cohort had an 11.6% decreased likelihood of a minor complication (p < 0.001); however, no difference was found between CMN and SHS for major complications (p = 0.117). SHS patients were less likely to have transfusion (p < 0.001), DVT (p = 0.007), and MI (0.024). SHS patients were 12.5% more likely to go home (p = 0.002). No association was discovered between being treated with a SHS and reoperation (p = 0.449) and readmission (p = 0.588). SHS patients had almost a quarter of a day longer LOS (p = 0.041). Patients treated with SHS had a statistically significant (p < 0.001), but clinically irrelevant 2-min longer procedure. LEVEL OF EVIDENCE III.

Abstract
OBJECTIVES Multiple systematic reviews have reported on the impact of rib fracture fixation in the presence of flail chest and multiple rib fractures, however this practice remains controversial. Our aim is to synthesise the effectiveness of surgical rib fracture fixation as evidenced by systematic reviews. DESIGN A systematic search identified systematic reviews comparing effectiveness of rib fracture fixation with non-operative management of adults with flail chest or unifocal non-flail rib fractures. MEDLINE, EMBASE, Cochrane Database of Systematic Reviews and Science Citation Index were last searched 17 March 2017. Risk of bias was assessed using the Risk Of Bias In Systematic reviews (ROBIS) tool. The primary outcome was duration of mechanical ventilation. RESULTS Twelve systematic reviews were included, consisting of 3 unique randomised controlled trials and 19 non-randomised studies. Length of mechanical ventilation was shorter in the fixation group compared with the non-operative group in flail chest; pooled estimates ranged from -4.52 days, 95% CI (-5.54 to -3.5) to -7.5 days, 95% CI (-9.9 to -5.5). Pneumonia, length of hospital and intensive care unit stay all showed a statistically significant improvement in favour of fixation for flail chest; however, all outcomes in favour of fixation had substantial heterogeneity. There was no statistically significant difference between groups in mortality. Two systematic reviews included one non-randomised studies of unifocal non-flail rib fracture population; due to limited evidence the benefits with surgery are uncertain. CONCLUSIONS Synthesis of the reviews has shown some potential improvement in patient outcomes with flail chest after fixation. For future review updates, meta-analysis for effectiveness may need to take into account indications and timing of surgery as a subgroup analysis to address clinical heterogeneity between primary studies. Further robust evidence is required before conclusions can be drawn of the effectiveness of surgical fixation for flail chest and in particular, unifocal non-flail rib fractures.

Impact of comorbidity on the association between surgery delay and mortality in hip fracture patients: A Danish nationwide cohort study. Injury 2019; 50:424-431. [PMID: 30616809 DOI: 10.1016/j.injury.2018.12.032] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2018] [Accepted: 12/27/2018] [Indexed: 02/02/2023]
Abstract
PURPOSE To examine the association between surgery delay and mortality in hip fracture patients with and without known comorbidity. METHODS We identified all patients with a first time hip fracture diagnose operated between January 1, 2010 and December 31, 2015 (n = 36,552). As a measure of comorbidity we used Charlson Comorbidity Index stratified in categories: none (no registered comorbidities prior fracture), medium (1-2 points) and high (≥3 points). RESULTS No association between surgery delay, regardless of the threshold, and 30-days mortality was observed among patients with high level of comorbidity. Surgery delay of >24h vs. ≤24 h was associated with higher 0-30-days mortality in patients with medium level of comorbidity (adjusted HR: 1.12 (95% CI: 1.01 ; 1.24)). In addition, surgery delay was associated with up to 45% increased mortality in patients with none comorbidity prior surgery, although the confidence intervals were wide. Furthermore, surgery delay of >24 h (vs. <24 h) and >48 h (vs. ≤48 h) was associated with higher 31-90-days mortality among all patients (adjusted HR: 1.19 (95% CI: 1.10 ; 1.29) and 1.35 (95% CI: 1.16 ; 1.56), respectively), but in particular among patients with none (adjusted HR: 1.26 (95% CI: 1.08 ; 1.47) and 1.65 (95% CI: 1.26 ; 2.17), respectively) and medium (adjusted HR: 1.21 (95% CI: 1.07 ; 1.36) and 1.25 (95% CI: 1.00 ; 1.57), respectively) level of comorbidity at the time of surgery. CONCLUSIONS There was an association between surgery delay and 30-days mortality in hip fracture surgery patients with none and medium level of comorbidity, whereas no such association was observed among hip fracture patients with a high comorbidity level. Surgery delay was associated with one year increased risk of dying in both patients with and without comorbidity prior surgery.

Length of hospital stay after hip fracture surgery and 1-year mortality. Osteoporos Int 2019; 30:145-153. [PMID: 30361752 DOI: 10.1007/s00198-018-4747-7] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2018] [Accepted: 10/18/2018] [Indexed: 11/30/2022]
Abstract
UNLABELLED There is ongoing effort to discharge patients early after hip fracture surgery to reduce the medical and economic burden. We tried to find whether there is any related side effect, and discovered that early discharge, especially before 10 days after surgery, is associated with higher mortality. INTRODUCTION The aim of this study was to analyze the association between the length of hospital stay after hip fracture and 1-year mortality in older adults aged ≥ 65 years old. METHODS We conducted a retrospective cohort study using the Korean National Health Insurance Service data to identify patients who were discharged after hip fracture surgery from 2007 to 2009 among 487,460 older adults of age ≥ 65 years. The lengths of stay involving hip fracture surgery were categorized at 10-day interval, and analyzed in relation to 1-year mortality from the date of hospital discharge. RESULTS A total of 4213 patients were discharged after hip fracture surgery, of whom 604 (14.3%) died within 1 year of discharge. The average length of stay was 30.7 days (standard deviation 24.5 days). The 1-year mortality was the highest for the length of stay ≤ 10 days group at 21.7%, followed by 15.2%, 14.3%, 13.3%, and 12.4% for > 40, 21-30, 31-40, and 11-20 days groups, respectively (p value 0.05). On Cox proportional hazard regression, the adjusted hazard ratio for length of stay ≤ 10 days group was 1.56 (95% confidence interval 1.14-2.12) against the reference group (11-20 days), while other groups did not show statistical significance. Higher risk of death was associated with increasing age, male gender, Charlson comorbidity index ≥3, subtrochanteric fracture, and discharge to tertiary care hospitals and long-term care hospitals. CONCLUSION Older adults discharged within 10 days of hospital admission for hip fracture surgery have higher 1-year mortality after discharge.

Home, No Follow-Up: Are we ignoring the significance of unplanned clinic attendances, re-admission and mortality in the first 12 months post-operatively in over 65 year olds' hip fractures treated with DHS fixation? Injury 2018; 49:662-666. [PMID: 29422294 DOI: 10.1016/j.injury.2018.01.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2017] [Revised: 12/16/2017] [Accepted: 01/06/2018] [Indexed: 02/02/2023]
Abstract
INTRODUCTION 80,000 hip fractures are admitted to UK hospitals annually (Royal College of Physicians, 2016). Little is known about 12-month post-operative re-admission, unplanned clinic attendance and mortality. We aimed to determine if there is a role for routine follow-up for certain strata of our hip fracture population treated by Dynamic Hip Screw (DHS) Fixation based on unplanned attendance to clinics and whether it is possible to stratify risk of re-admission, re-operation and mortality within the first 12 months post-operatively. METHODS A prospectively collated single centre database of patients >65 years old undergoing DHS fixation for traumatic hip fractures between August 2007 and February 2011 was retrospectively analysed. Pre-operative data regarding patient demographics, mobility, residence and co-morbidities were collected. Post-operative (1, 4, 12 months) place of residence, mobility status, unplanned attendance to an orthopaedic clinic with symptoms relating to the respective limb, re-admission to hospital and mortality was collated. Regression analysis was performed (SPSS, IBM Corporation, version 24). P < 0.05 was considered significant. RESULTS 648 consecutive patients were identified. Increasing age (p = 0.006) and presence of pressure sores during initial admission (p = 0.0019) increased the frequency of unplanned clinic attendance. No significant predictors of re-admission to hospital were found. Overall mortality was related to increasing age (p = 0.042), male gender (p = 0.004) and ASA grade (p = 0.009). CONCLUSION There is no current vogue to follow-up such patients in this post-operative period. We have identified variables that should be sought prior to discharge in this population. 22% of our population had at least one unplanned clinic attendance with a cost implication of approximately £50,132 (£151 per appointment) over the study period and potentially over £1.6 million pounds annually in the U.K. IMPLICATIONS Formal follow-up/rehabilitation programs could be offered for those at risk of unplanned clinic attendance. Post-operative orthogeriatric and/or general practitioner follow-up may reduce 12-month mortality in those at risk but validated scoring and risk stratification systems are required to fully justify this.

Abstract
UNLABELLED The evidence is limited regarding the association between socioeconomic status and the clinical outcome among patients with hip fracture. In this nationwide, population-based cohort study, higher education and higher family income were associated with a substantially lower 30-day mortality and risk of unplanned readmission after hip fracture. INTRODUCTION We examined the association between socioeconomic status and 30-day mortality, acute readmission, quality of in-hospital care, time to surgery and length of hospital stay among patients with hip fracture. METHODS This is a nationwide, population-based cohort study using prospectively collected data from the Danish Multidisciplinary Hip Fracture Registry. We identified 25,354 patients ≥65 years admitted with a hip fracture between 2010 and 2013 at Danish hospitals. Individual-level socioeconomic status included highest obtained education, family mean income, cohabiting status and migrant status. We performed multilevel regression analysis, controlling for potential confounders. RESULTS Hip fracture patients with higher education had a lower 30-day mortality risk compared to patients with low education (7.3 vs 10.0% adjusted odds ratio (OR) = 0.74 (95% confidence interval (CI) (0.63-0.88)). The highest level of family income was also associated with lower 30-day mortality (11.9 vs 13.0% adjusted OR = 0.77, 95% CI 0.69-0.85). Cohabiting status and migrant status were not associated with 30-day mortality in the adjusted analysis. Furthermore, patients with both high education and high income had a lower risk of acute readmission (14.5 vs 16.9% adjusted OR = 0.94, 95% CI 0.91-0.97). Socioeconomic status was, however, not associated with quality of in-hospital care, time to surgery and length of hospital stay. CONCLUSIONS Higher education and higher family income were associated with substantially lower 30-day mortality and risk of readmission after hip fracture.

Internal fixation of intra-capsular proximal femoral fractures in patients older than 80 years: Still relevant? Multivariate analysis of a prospective multicentre cohort. Orthop Traumatol Surg Res 2017; 103:3-7. [PMID: 27919767 DOI: 10.1016/j.otsr.2016.10.013] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Revised: 09/21/2016] [Accepted: 10/06/2016] [Indexed: 02/02/2023]
Abstract
BACKGROUND Arthroplasty is now widely used to treat intra-capsular proximal femoral fractures (PFFs) in older patients, even when there is little or no displacement. However, whether arthroplasty is associated with lower mortality and complication rates in non-displaced or mildly displaced PFFs is unknown. The objectives of this prospective study were: (1) to evaluate early mortality rates with the two treatment methods, (2) to identify risk factors for complications, (3) and to identify predictors of functional decline. HYPOTHESIS Arthroplasty and internal fixation produce similar outcomes in non-displaced fractures of patients older than 80 years with PFFs. MATERIAL AND METHODS This multicentre prospective study included consecutive patients older than 80 years who were managed for intra-capsular PFFs at eight centres in 2014. Biometric data and geriatric assessment scores (Parker Mobility Score, Katz Index of Independence, and Mini-Nutritional Assessment [MNA] score) were collected before and 6 months after surgery. Independent risk factors were sought by multivariate analysis. We included 418 females and 124 males with a mean age of 87±4years. The distribution of Garden stages was stage I, n=56; stage II, n=33; stage III, n=130; and stage IV, n=323. Arthroplasty was performed in 494 patients and internal fixation in 48 patients with non-displaced intra-capsular PFFs. RESULTS Mortality after 6 months was 16.4% overall, with no significant difference between the two groups. By multivariate analysis, two factors were significantly associated with higher mortality, namely, male gender (odds ratio [OR], 3.24; 95% confidence interval [95% CI], 2.0-5.84; P<0.0001) and high ASA score (OR, 1.56; 95% CI, 1.07-2.26; P=0.019). Two factors were independently associated with lower mortality, with 75% predictive value, namely, high haematocrit (OR, 0.8; 95% CI, 0.7-0.9; P=0.001) and better Parker score (OR, 0.5; 95% CI, 0.3-0.8; P=0.01). The cut-off values associated with a significant risk increase were 2 for the Parker score (OR, 1.8; 95% CI, 1.1-2.3; P=0.001) and 37% for the haematocrit (OR, 3.3; 95% CI, 1.9-5.5; P=0.02). Complications occurred in 5.5% of patients. Surgical site infections were seen in 1.4% of patients, all of whom had had arthroplasty. Blood loss was significantly greater with arthroplasty (311±197mL versus 201±165mL, P<0.0002). Dependency worsened in 39% of patients, and 31% of patients lost self-sufficiency. A higher preoperative Parker score was associated with a lower risk of high postoperative dependency (OR, 0.86; 95% CI, 0.76-0.97; P=0.014). DISCUSSION Neither treatment method was associated with decreased mortality or better function after intra-capsular PFFs in patients older than 80 years. Early mortality rates were consistent with previous reports. Among the risk factors identified in this study, age, preoperative self-sufficiency, and gender are not amenable to modification, in contrast to haematocrit and blood loss. CONCLUSION Internal fixation remains warranted in patients older than 80 years with non-displaced intra-capsular PFFs. LEVEL OF EVIDENCE III, prospective case-control study.

Abstract
BACKGROUND Proximal femur fractures are common and treatment is expensive. The aim of the present study was - after matching of hospital and health insurance data - to evaluate the influence of early operation on certain outcome parameters. Data from a German health insurance were used to identify then influence of the day of operation after admittance on the rate of mortality, decubitus, and revision surgery during the hospital stay and on the care level of the patients up to 1 year and in some cases longer after operation. MATERIALS AND METHODS In all, 7905 patients were included. The descriptive data, specifying the given population, described the hospital stay (occurrence, surgical procedures, early complications, secondary diagnoses, length of stay) and the course of patient recovery up to 1 year after the hospital stay (care level, late complications). The calculated data (analytical statistics) give correlations evaluating the influence of the length of the preoperative hospital stay on the outcome parameters mentioned above. Risk adjustment was performed by using secondary diagnoses. RESULTS The study included more women (mean age 81.5 years). Most common was the femoral neck fracture. Of the operations 77% were carried out on the first day after admission; dominating procedures were intramedullary nails and prostheses. Most common secondary diagnoses were diabetes, dementia, ischemic heart disease, and chronic heart insufficiency. Descriptive data revealed 6% early as well as late complications. In all, 50% of patients had a higher care level after operation. Almost 40% of patients changed from outpatient care to inpatient care. The time interval between admission and operation negatively influenced all outcome parameters. The relative risk to die, to develop decubitus, or to receive early revision was increased by approximately one third when patients were operated on later than the first day after admission. A total of 3172 patients died during the study period. Mortality after operation reached 9.9% within 30 days and 26.9% at 1 year. The mortality of patients operated after the first day was increased by more than 6% compared to patients treated within the first 24 h. CONCLUSION The present study clearly presents the importance of analysis of routine records after discharge and it demonstrates that longer periods up to 1 year and more can be evaluated. The data show that a longer time period between hospital admission and operation negatively influences all outcome parameters. The care data give impressive evidence for a significant loss of quality of life and the importance of intense postoperative rehabilitation.

Abstract
Femur fracture is an emerging public health concern in aging societies, owing to the substantially high morbidity and mortality. Because the recent increase in femur fracture incidence in Asian populations is comparable to that in the West, it is necessary to investigate the association between socioeconomic status (SES) and mortality after femur fracture in developed Asian societies.Data were obtained from the National Health Insurance Claims Database. During 2002 to 2013, femur fractures were newly diagnosed in 5441 patients among 1025,340 enrollees. Multiple logistic regression and the Cox proportional model were used to investigate the associations between individual SES and probability of surgery and mortality after femur fracture.Of 5441 patients, 1928 (35.4%) received surgery. Patients with low (odds ratio [OR] = 0.87, 95% confidence interval [CI]: 0.75-0.99) and middle (OR = 0.85, 95% CI: 0.74-0.98) income were less likely to undergo surgery than high-income patients. Patients with low (hazard ratio [HR] = 1.12, 95% CI: 1.01-1.24) and middle (HR = 1.20, 95% CI: 1.08-1.33) income had a higher HR for mortality. This difference was more prominent in patients who underwent surgery (low income: HR = 1.07, 95% CI: 0.94-1.21; middle income: HR = 1.18, 95% CI: 1.04-1.33) than in patients with conservative treatment (low income: HR = 1.24, 95% CI: 1.04-1.49; middle income: HR = 1.30, 95% CI: 1.08-1.56).Femur-fracture patients with low SES are less likely to receive surgery for and more likely to die after femur fracture. The difference in mortality risk remained even when only the patients who received surgery were considered, suggesting that we need to consider support measures for these deprived patients.

Risk scoring models for predicting peri-operative morbidity and mortality in people with fragility hip fractures: Qualitative systematic review. Injury 2015; 46:2325-34.

Abstract
RATIONALE Accurate peri-operative risk prediction is an essential element of clinical practice. Various risk stratification tools for assessing patients' risk of mortality or morbidity have been developed and applied in clinical practice over the years. This review aims to outline essential characteristics (predictive accuracy, objectivity, clinical utility) of currently available risk scoring tools for hip fracture patients. METHODS We searched eight databases; AMED, CINHAL, Clinical Trials.gov, Cochrane, DARE, EMBASE, MEDLINE and Web of Science for all relevant studies published until April 2015. We included published English language observational studies that considered the predictive accuracy of risk stratification tools for patients with fragility hip fracture. RESULTS After removal of duplicates, 15,620 studies were screened. Twenty-nine papers met the inclusion criteria, evaluating 25 risk stratification tools. Risk stratification tools considered in more than two studies were; ASA, CCI, E-PASS, NHFS and O-POSSUM. All tools were moderately accurate and validated in multiple studies; however there are some limitations to consider. The E-PASS and O-POSSUM are comprehensive but complex, and require intraoperative data making them a challenge for use on patient bedside. The ASA, CCI and NHFS are simple, easy and inexpensive using routinely available preoperative data. Contrary to the ASA and CCI which has subjective variables in addition to other limitations, the NHFS variables are all objective. CONCLUSION In the search for a simple and inexpensive, easy to calculate, objective and accurate tool, the NHFS may be the most appropriate of the currently available scores for hip fracture patients. However more studies need to be undertaken before it becomes a national hip fracture risk stratification or audit tool of choice.

Abstract
UNLABELLED This study retrospectively reviewed 327 nonagenarians who underwent hip fracture surgery at six hospitals. Functional status, postoperative complications, and 1-year mortality were evaluated, and relationships between these factors and American Society of Anesthesiologists (ASA) grade were analyzed. ASA grade was significantly associated with postoperative complications and 1-year mortality. INTRODUCTION Few previous studies have reported outcomes after hip fracture in nonagenarians, and these studies did not report significant associations between ASA grade and mortality. However, most of these studies included only a small number of patients from a single hospital. This study aimed to evaluate the relationships between ASA grade and functional status, postoperative complications, and mortality rate in nonagenarians undergoing hip fracture surgery. METHODS This study included 327 nonagenarians who underwent hip fracture surgery between January 2000 and December 2012. Patients with open fractures, subtrochanteric fractures, polytrauma, and pathological fractures were excluded. The medical records and X-rays were retrospectively reviewed. The relationships between ASA grade and functional status, postoperative complications, and 1-year mortality were analyzed. RESULTS There were significant associations between the ASA grade and the rates of postoperative complications and 1-year mortality (both p < 0.05). All pairwise comparisons showed significant differences in postoperative complication rates between ASA grades (all p < 0.05). All pairwise comparisons, except for grades I vs. II and grades II vs. III, also showed significant differences in mortality rates between ASA grades (all p < 0.05). There were significant associations between the preoperative ability to manage activities of daily living and the rates of postoperative complications and 1-year mortality (both p < 0.05). CONCLUSIONS ASA grade was significantly associated with the rates of postoperative complications and 1-year mortality in nonagenarians undergoing hip fracture surgery. The preoperative functional status was also significantly associated with these outcomes.

Percutaneous compression plate versus dynamic hip screw for treatment of intertrochanteric Hip fractures: a meta-analyse of five randomized controlled trials. ScientificWorldJournal 2014; 2014:512512. [PMID: 24737975 PMCID: PMC3967693 DOI: 10.1155/2014/512512] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2013] [Accepted: 12/11/2013] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Percutaneous compression plating (PCCP) has been advocated to reduce blood loss, relieve pain, and lead to faster rehabilitation for the treatment of intertrochanteric fractures. The purpose of this meta-analysis was to estimate the outcomes and complications of the PCCP versus dynamic hip screw (DHS) fixation for intertrochanteric fractures. METHODS All randomized controlled trials (RCT) that compared PCCP with DHS in treating adult patients with intertrochanteric fractures were included. Main outcomes were collected and analysed using the RevMan 5.1 version. RESULTS Five trials met the inclusion criteria. Compared with DHS, PCCP had similar operation time (95% CI: -26.01~4.05, P = 0.15), length of hospitalization (95% CI: -1.79~1.25, P = 0.73), mortality (95% CI: 0.37~1.02, P = 0.06), incidence of implant-related complications (95% CI: 0.29~1.82, P = 0.49), and reoperation rate (95% CI: 0.41~3.05, P = 0.83). But blood loss (95% CI: -173.84~-4.81, P = 0.04) and transfusion need (95% CI: -0.53~-0.07, P = 0.01) significantly favored the PCCP. CONCLUSIONS The PCCP was associated with reduced blood loss and less transfusion need, but similar to DHS in other respects. Owing to the limitations of this systematic review, more high-quality RCTs are still needed to assess the clinical efficiency of PCCP.

Abstract
Geriatric acetabular, pelvis, and subtrochanteric femur fractures are poorly understood and rapidly growing clinical problems. The purpose of this study was to describe the epidemiologic trends of these injuries as compared with traditional fragility fractures about the hip. From 1993 to 2010, the Nationwide Inpatient Sample (NIS) recorded more than 600 million Medicare-paid hospital discharges. This retrospective study used the NIS to compare patients with acetabular fractures (n=87,771), pelvic fractures (n=522,831), and subtrochanteric fractures (n=170,872) with patients with traditional hip fractures (intertrochanteric and femoral neck, n=3,495,742) with regard to annual trends over an 18-year period in incidence, length of hospital stay, hospital mortality, transfers from acute care institutions, and hospital charges. Traditional hip fractures peaked in 1996 and declined by 25.7% by 2010. During the same 18-year period, geriatric acetabular fractures increased by 67%, subtrochanteric femur fractures increased by 42%, and pelvic fractures increased by 24%. Hospital charges, when controlling for inflation, increased roughly 50% for all fracture types. Furthermore, transfers from outside acute care hospitals for definitive management stayed elevated for acetabular fractures as compared with traditional hip fractures, suggesting a greater need for tertiary care of acetabular fractures. Geriatric acetabular fractures are rapidly increasing, whereas traditional hip fractures continue to decline. Patients with these injuries are more likely to be transferred from their hospital of presentation to another acute care institution, possibly increasing costs and complications. This is likely related to their complexity and the lack of consensus regarding optimal management.

Abstract
The purpose of this study was to determine the incidence of and evaluate the risk for complications and mortality following open treatment of acetabular fractures in the Medicare population. Patients treated with open reduction and internal fixation (ORIF) for acetabular fractures were identified using current procedural terminology codes in a 5% national sample of Medicare records. Complications within 90 days and within 1 year were evaluated based on the presence of ICD-9-CM diagnosis codes and Current Procedural Terminology reoperation codes. A total of 1286 fractures were treated closed and 359 were treated with ORIF. Multivariate Cox regression was performed to compare complication rates and risk factors. The incidence of acetabular fractures in the Medicare population has increased by 29% since 1998. Complications in the ORIF group included cardiac complications, deep venous thrombosis, infection, pulmonary embolism, refixation, and conversion to total hip arthroplasty. Risk factors for complications with ORIF included advanced age and comorbidities. Mortality in the ORIF group was 14.4% at 1 year. The incidence of reoperation with conversion to total hip arthroplasty or revision fixation following ORIF is 10% and 15%, respectively. Further investigation is required to improve outcomes and decrease complications in this group of patients, especially cardiac, deep vein thrombosis, and infection.

Abstract
Limited data are available on the use of internal fixation in combat zone hospitals. The authors performed a retrospective review of 713 surgical cases during 2 Operation Enduring Freedom deployments to a Level III theater hospital in 2007 and 2009 to 2010. The epidemiology and short- to intermediate-term outcomes of patients treated with internal fixation devices were studied. The authors found that, with judicious use, internal fixation under a damage control protocol in a combat theater hospital can be performed with acceptable complication rates.

Abstract
Although functional outcomes of hip joint reconstruction may be superior to those of internal fixation, differences in mortality between the 2 procedures are poorly defined. We conducted a retrospective study of patients 50 years and older with femoral neck fracture treated with joint reconstruction or internal fixation, performing adjusted logistic regressions to compare the odds of inpatient and 30-day mortality among patients according to surgery type. Of 12,867 patients with femoral neck fracture, 9001 had joint reconstruction and 3866 had internal fixation. After adjustment for patient factors alone, the odds of inpatient mortality were higher with reconstruction (OR, 1.62; 95% CI, 1.18-2.23; P=.003); however, the difference in the odds of 30-day mortality did not achieve statistical significance (OR, 1.18; 95% CI, 1.00-1.41; P=.053). Controlling for patient and hospital factors, we found higher odds of both inpatient mortality (OR, 1.65; 95% CI, 1.19-2.28; P=.003) and 30-day mortality (OR, 1.22; 95% CI, 1.02-1.46; P=.026) with reconstruction. Joint reconstruction is associated with a 60% increase in the odds of inpatient mortality after femoral neck fracture.

Use of the Gamma3™ nail in a teaching hospital for trochanteric fractures: mechanical complications, functional outcomes, and quality of life. BMC Res Notes 2012; 5:651. [PMID: 23176260 PMCID: PMC3534554 DOI: 10.1186/1756-0500-5-651] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2012] [Accepted: 11/21/2012] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND Trochanteric fractures are common fractures in the elderly. Due to characteristic demographic changes, the incidence of these injuries is rapidly increasing. Treatment of these fractures is associated with high rates of complications. In addition, the long-term results remain poor, with high morbidity, declines in function, and high mortality. Therefore, in this study, complication rates and patients' outcomes were evaluated after fixation of geriatric trochanteric fractures using the Gamma3™ nail. METHODS Patients aged 60 years old or older, with pertrochanteric and subtrochanteric femoral fractures, were included. Patients with polytrauma or pathological fractures were excluded. Age, sex, and fracture type were collected on admission. In addition, data were recorded concerning the surgeon (resident vs. consultant), time of operation, and local or systemic perioperative complications. Complications were also collected at the 6- and 12-month follow-ups after trauma. Barthel Index, IADL, and EQ-5D measurements were evaluated retrospectively on admission, as well as at discharge and during the follow-up. RESULTS Ninety patients were prospectively included between April 2009 and September 2010. The patients' average age was 81 years old, and their average ASA score was 3. The incision/suture time was 53 min (95% CI 46-60 min). Hospital mortality was 4%, and overall mortality was 22% at the 12-month follow-up. Eight local complications occurred (4 haematomas, 1 deep infection, 1 cutting out, 1 irritation of the iliotibial tract, 1 periosteosynthetic fracture). The incidence of relevant systemic complications was 6%. Forty-two percent of the patients were operated on by residents in training, without significant differences in duration of surgery, complication rate, or mortality rate. The Barthel Index (82 to 71, p < .001), IADL (4.5 to 4.3, p = .0195) and EQ-5-D (0.75 to 0.66, p = .068) values did not reach pre-fracture levels during the follow-up period of 12 months. CONCLUSION The results showed a relatively low complication rate using the Gamma3™ nail, even if the nailing was performed by residents in training. The high mortality, declines in function, and low quality of life could probably be attributed to pre-existing conditions, such as physical status.In summary, the Gamma3™ nail seems to be a useful implant for the nailing of trochanteric fractures, although further studies are necessary comparing different currently available devices.

Deep infection after hip fracture surgery: predictors of early mortality. Injury 2012; 43:1182-6. [PMID: 22542166 DOI: 10.1016/j.injury.2012.03.029] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2012] [Revised: 01/30/2012] [Accepted: 03/28/2012] [Indexed: 02/02/2023]
Abstract
INTRODUCTION This study analysed the predictors of mortality in patients who are diagnosed with deep infection following hip fracture surgery. METHODS Data were prospectively collected for 3 years from all patients undergoing hip fracture surgery and who had developed a subsequent deep infection. Infection was defined as positive microbiology culture from deep tissue or fluid samples. Demographic data, treatment, complications and subsequent surgeries were analysed. Potential predisposing factors including chronic medical co-morbidities, American Society of Anesthesiologists (ASA) grade, alcohol excess and smoking were assessed. The main outcome measures were 30-day and 1-year mortality. RESULTS There were 2718 consecutive operations performed for a fracture of the proximal femur over a 3-year period. Forty-three (1.6%) patients had a deep postoperative infection diagnosed on fluid and/or tissue sampling. The mean age was 73 years (25-94) and 65% were female. Of the 43 patients who developed deep infection, the primary procedure in 25 (58%) patients was reduction and internal fixation, with 18 (42%) undergoing hemi-arthroplasty. The most common causative organism was Staphylococcus epidermidis (n=13, 30%), with methicillin-resistant Staphylococcus aureus (MRSA) accounting for 23% (n=10). The 30-day mortality was significantly higher than that of patients with no deep infection (19% vs. 6.5%; p=0.004). On univariate analysis, increasing age, dementia and diabetes were predictive of both 30-day and 1-year mortality (all p<0.05). S. aureus (sensitive or resistant) was approaching significance at 1 year (p=0.065). On multivariate analysis, dementia and diabetes were independent predictors of 30-day mortality, with dementia and S. aureus predictive at 1 year. CONCLUSIONS The 30-day mortality rate in patients diagnosed with deep infection following hip fracture surgery is higher than those without infection. Dementia, diabetes and S. aureus infection are independent predictors of mortality following deep infection.

Monoblock hemiarthroplasties for femoral neck fractures--a part of orthopaedic history? Analysis of national registration of hemiarthroplasties 2005-2009. Injury 2012; 43:946-9.

Abstract
This study from the Swedish Hip Arthroplasty Register (SHAR) compares cemented (Thompson(®), Exeter Trauma Stem (ETS)(®)) and uncemented (Austin-Moore(®)) monoblock hemiarthroplasties (n=1116 and 616, respectively) with modular ones (n=18,659). Austin-Moore(®) prostheses lead to more re-operations (6.7%) compared to modular implants (3.5%) and Thompson(®)/ETS(®) (2.4%). A Cox regression analysis, adjusting for other risk factors, shows twice the risk of re-operation for Austin-Moore(®) implants (CI 1.5-2.8), in particular, due to periprosthetic fracture (5.4; CI 3.2-9.1) and dislocation (1.9; CI 1.3-3.0). The Thompson(®)/ETS(®) implants do not influence the overall risk of re-operation (0.7; CI 0.5-1.2) compared to modular implants and decrease the risk of re-operation due to infection (0.2;CI 0.04-0.7). An increased risk of re-operation is also seen in men, age groups 75-85 years and <75 years and after secondary fracture surgery. Both Swedish and Australian orthopaedic surgeons have decreased their use of Austin-Moore(®) implants after reports from their national arthroplasty registers identifying inferior outcome for this implant. Due to the increased risk of re-operations, it should not be used in modern orthopaedic care. Cemented Thompson(®) or ETS(®) implants could still be suitable for the oldest, low-activity patients. To finally decide if there is a place for them, patient-reported outcome must be analysed as well.

Abstract
In Denmark, 10,000 patients with hip fractures are annually admitted to hospital. These patients are generally old with a high degree of comorbidities. Current treatment strategies for peri- and postoperative treatment are presented in relation to patient reconvalescence. Overall expected hospitalization is 5-25 days with 1-3 months of analgesic treatment and physiotherapy. The 30-day mortality is 10% and the reoperation rate is 10-20%. The use of specialized centres and accelerated clinical programmes in Denmark is recommended.

Abstract
Hemiarthroplasty is the most commonly used treatment for displaced femoral neck fractures in the elderly. There is limited evidence in the literature of improved functional outcome with cemented implants, although serious cement-related complications have been reported. We performed a randomized, controlled trial in patients 70 years and older comparing a cemented implant (112 hips) with an uncemented, hydroxyapatite-coated implant (108 hips), both with a bipolar head. The mean Harris hip score showed equivalence between the groups, with 70.9 in the cemented group and 72.1 in the uncemented group after 3 months (mean difference, 1.2) and 78.9 and 79.8 after 12 months (mean difference, 0.9). In the uncemented group, the mean duration of surgery was 12.4 minutes shorter and the mean intraoperative blood loss was 89 mL less. The Barthel Index and EQ-5D scores did not show any differences between the groups. The rates of complications and mortality were similar between groups. Both arthroplasties may be used with good results after displaced femoral neck fractures.

Abstract
BACKGROUND the impact of anaemia on the outcome after a hip fracture surgery is controversial, but anaemia can potentially decrease the physical performance and thereby impede post-operative rehabilitation. We therefore conducted a prospective study to establish whether anaemia affected functional mobility in the early post-operative phase after a hip fracture surgery. PATIENTS AND METHODS four hundred and eighty seven consecutive hip fracture patients, treated according to a well-defined multimodal rehabilitation programme with a uniform, liberal transfusion threshold, were studied. Hb was measured on each of the first three post-operative days, and anaemia defined as Hb <100 g/l. Functional mobility was measured with the Cumulated Ambulation Score (CAS). RESULTS the results were obtained from 170, 132 and 116 patients who were found anaemic on the first, second and third post-operative day, respectively. A significant association between anaemia and the ability to walk independently before the correction of anaemia was present on each of the 3 days separately (P<0.05). A significant correlation was also found on each day between the functional score and the Hb level. A multivariate analysis integrating the type of surgery, medical complications and prefracture function showed that anaemia at the time of the physiotherapy session was an independent risk factor for not being able to walk on the third post-operative day [OR 0.41 (0.14-0.73) P = 0.002]. CONCLUSION anaemia impedes functional mobility in the early post-operative phase after a hip fracture surgery and is an independent risk factor for patients not being able to walk post-operatively. The potential for a liberal transfusion policy to improve the rehabilitation potential in hip fracture patients with anaemia should be investigated.

Abstract
BACKGROUND Hip fracture surgery is associated with high post-operative mortality and poor functional results: the excess mortality is 20% in the first year; of those patients who survive, only 50% recover their previous ability to walk. The purpose of this study was to assess the predictive value of six functional status and/or surgical risk scoring systems with regard to serious complications after hip fracture surgery in the elderly. METHODS We performed a prospective study of a consecutive series of 232 patients (aged 65 years or older) undergoing hip fracture surgery. We pre-operatively applied: The American Society of Anesthesiologists classification, the Barthel index, the Goldman index, the Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (POSSUM) scoring system, the Charlson index and the Visual Analogue Scale for Risk (RISK-VAS) scale. These scales were evaluated with respect to three variables: incidence of serious complications, the ability to walk after a 3-month period and 90-day survival. The predictive value of the different scales was assessed by the calculated area under a receiver operating characteristic curve. RESULTS The RISK-VAS scale, the POSSUM scoring system and the Charlson index reached a sufficient predictive value with regard to serious post-operative complications. The Barthel index and the RISK-VAS scale were those most useful for predicting ambulation at 3 months. None of the scales proved to be capable of predicting 90-day mortality. CONCLUSIONS A simple index such as the RISK-VAS scale was the best predictor of serious post-operative complications. The functional level before the fracture, measured with the Barthel index, had a major influence on the ambulation recovery.

Abstract
OBJECTIVE To compare the functional results after displaced fractures of the femoral neck treated with internal fixation or hemiarthroplasty. DESIGN Randomised trial with blinding of assessments of functional results. SETTING University hospital. PARTICIPANTS 222 patients; 165 (74%) women, mean age 83 years. Inclusion criteria were age above 60, ability to walk before the fracture, and no major hip pathology, regardless of cognitive function. INTERVENTIONS Closed reduction and two parallel screws (112 patients) and bipolar cemented hemiarthroplasty (110 patients). Follow-up at 4, 12, and 24 months. MAIN OUTCOME MEASURES Hip function (Harris hip score), health related quality of life (Eq-5d), activities of daily living (Barthel index). In all cases high scores indicate better function. RESULTS Mean Harris hip score in the hemiarthroplasty group was 8.2 points higher (95% confidence interval 2.8 to 13.5 points, P=0.003) at four months and 6.7 points (1.5 to 11.9 points, P=0.01) higher at 12 months. Mean Eq-5d index score at 24 months was 0.13 higher in the hemiarthroplasty group (0.01 to 0.25, P=0.03). The Eq-5d visual analogue scale was 8.7 points higher in the hemiarthroplasty group after 4 months (1.9 to 15.6, P=0.01). After 12 and 24 months the percentage scoring 95 or 100 on the Barthel index was higher in the hemiarthroplasty group (relative risk 0.67, 0.47 to 0.95, P=0.02. and 0.63, 0.42 to 0.94, P=0.02, respectively). Complications occurred in 56 (50%) patients in the internal fixation group and 16 (15%) in the hemiarthroplasty group (3.44, 2.11 to 5.60, P<0.001). In each group 39 patients (35%) died within 24 months (0.98, 0.69 to 1.40, P=0.92) CONCLUSIONS Hemiarthroplasty is associated with better functional outcome than internal fixation in treatment of displaced fractures of the femoral neck in elderly patients.

Abstract
In a retrospective study, 1.173 fractures of the proximal femur, which had been treated surgically, were analysed in two periods from 1975 to 1991 and from 1992 to 2000. The influence on mortality of preoperative risk factors and primary treatment with total hip replacement (THR), even in cases of pertrochanteric fractures, was analysed by stepwise logistic regression. In the later period, mortality within 90 days was 13.1%, and within 1 year 22.2%. Rejection of hemiendoprosthesis in high-risk patients with intracapsular fractures increased the mortality rate from 6.3% to 11.8%. The introduction of dynamic hip screws instead of Ender nails led to a reduction of mortality from 16.5 to 7.1%. Higher mortality after THR (27.6%) compared to osteosynthesis (15.5%) in pertrochanteric femur and lateral neck fractures was due to higher age and increased risk factors. Although the influence of some risk factors could be reduced, age, sex and morbidity influenced the outcome more than surgical treatment. THP, even after pertrochanteric fractures, is reasonable if it guarantees a quick and enduring mobilisation of the patient. Bicentric bipolar prostheses are recommended for high risk patients.

Abstract
BACKGROUND Studies have shown that the degree of initial displacement and also comminution of the femoral calcar, size of the head and varus angulation are prognostic of failure in displaced femoral neck fracture. We have applied these radiographic criteria in order to select patients who would benefit from internal fixation as opposed to primary hemiarthroplasty, and this prospective study was conducted in order to monitor the results of this strategy. METHODS 683 displaced fractures of the femoral neck were treated with internal fixation or primary hemiarthroplasty based on the proposed radiographic criteria in a prospective consecutive study, and the patients were followed for 1-6 years. We treated 228 fractures with internal fixation and 455 by bipolar hemiprosthesis. The choice of operation was based on clinical evaluation of the patient and assessment of the assumed healing potential of the fracture, as determined by radiographic evaluation. Revision and mortality were primary endpoints. RESULTS 54 (24%) of the patients originally treated by osteosynthesis were revised, whereas 9 (2%) of the patients treated with hemiarthroplasty had revision surgery. There were no significant differences in mortality between the groups at 30, 120 or 365 days. INTERPRETATION Even when treating only the fractures with the assumed best healing potential with internal fixation, the results are inferior to hemiarthroplasty.

Abstract
BACKGROUND The aim of this study was to assess the disability and mortality of hip fractures 1 year after initial visit (postoperatively) at fixed-point hospitals selected by the Japanese Orthopaedic Association Committee on Osteoporosis. METHOD A total of 158 core orthopedic hospitals were selected for participation in this research. Subjects were all aged 65 years and older with hip fractures at the selected hospitals between January 1, 1999 and December 31, 2001. A prognostic survey of activities of daily living (ADL), assessed by the long-term care insurance criteria established by the Ministry of Health, Labour, and Welfare of Japan was performed 1 year after the initial visit. RESULTS A total of 1992 hip fractures in patients aged 65 to 111 years were treated over the 3 years from 1999 to 2001. Among the 1992 patients, 4537 had femoral neck fractures and 6217 had trochanteric fractures. Surgical treatment was chosen for 85.6% of the femoral neck fractures and 88.2% of the trochanteric fractures. The mean duration from fracture to admission was 3.1 days, and the mean duration from admission to surgery was 11.2 days. The mean duration from surgery to discharge over the 3-year period was 49.8 days. Before hip fracture, the ratio of patients with J1 ("able to go out freely utilizing public transportation") or J2 ("able to visit immediate neighbors independently") on the long-term care insurance criteria was 50.9%. At 1 year after the initial visit, that result represented a decrease of 24.1 percentage points before hip fracture. A total of 70 patients died before undergoing surgery. In the present study, the 1-year mortality rate for the entire patient population over the 3-year period was 10.1%. CONCLUSIONS Hip fracture patients show a decrease in the ADL score 1 year after the initial visit. Compared to other countries, the duration of hospitalization is longer in Japan, but the mortality rate is lower.

Perioperative morbidity and 30-day mortality after intertrochanteric hip fractures treated by internal fixation or arthroplasty. J Arthroplasty 2005; 20:963-6.

Abstract
The conventional treatment for intertrochanteric hip fracture is open reduction and internal fixation. However, hip arthroplasty is occasionally performed. The objective of this study was to determine the 30-day mortality for patients with intertrochanteric hip fracture treated with open reduction, internal fixation, or hip arthroplasty. The mortality rate for patients treated with arthroplasty at 4.8% (23/478) was slightly, but not significantly, higher than that for patients treated with open reduction and internal fixation at 4.5% (62/1395). However, more of the patients in the arthroplasty group exhibited serious intraoperative cardiorespiratory disturbances (62% vs 22%) and died in the hospital (77% vs 35%) when compared with the patients in the open reduction and internal fixation group. Although the incidence of 30-day mortality in these groups was not significantly different, the patients in the arthroplasty group were more likely to have a complicated intraoperative course and die in the hospital.

Abstract
Fixation is used to treat more than two-thirds of proximal femur fractures. The mortality rate is about 25% at one year in these patients, who have an average age of about 80 years. This is mainly due to aging, but also to a gradual deterioration of general health (especially if the operation has been delayed, or after a long stay in the surgical ward) and to local complications (displacement, infection, hematoma). Two fixation devices (a sliding screw plate and a trochanteric nail) have been designed for mini-invasive treatment with fluoroscopic guidance and an incision smaller than 50 mm. The aim is to respect the soft tissues and thereby to avoid local complications, diminish pain, and facilitate early weight-bearing Hospital discharge is possible after 3 or 4 days. Laboratory experiments have shown the satisfactory resistance of the implant and bone at full weight bearing A preliminary series of 30 patients showed the feasibility of these techniques. Primary fusion was achieved in 27 cases. There were no infections and no bleeding, despite antiplatelet treatment. The techniques have now been optimized and multicenter studies are held to determine their real benefit. Fracture fusion and hip motion should be at least as good as with open surgery (90 to 96% fusions, albeit influenced by the precise position of the implants and by osteoporosis). Mortality may be slightly reduced, thanks to immediate operation, early discharge, and fewer local complications. The cost of treatment could also be significantly reduced by the shorter hospital stay. In a few years' time, mini-invasive treatment may become the standard for elderly patients with proximal femur fractures.

Abstract
PURPOSE The aim of the study was to evaluate the mortality following the operative treatment of undisplaced subcapital fracture of the hip by internal fixation (with three lag screws) or hemiarthroplasty. METHODS A prospective audit of all patients admitted with hip fracture was undertaken at the university hospital in Nottingham. An independent research assistant collected data on a standardised questionnaire. Mortality was calculated from data received from National office of Statistics allowing 100% 1-year follow up for mortality statistics. RESULTS One hundred and sixty patients were admitted with undisplaced intracapsular fracture of the hip. Twenty-one patients had non-operative management and were excluded from the results. One hundred and thirty-nine patients had surgical treatment. Mean age of patients was 78 years. Twenty-nine patients had hemiarthroplasty and 110 patients underwent internal fixation of their fractures. There was no significant difference between the two groups for age, sex, mobility, residential status, co-morbidity and cognitive state. There was a significant difference in mortality between the two operated groups at 1 month and 1 year after the operation. Six patients (21%) died after hemiarthroplasty in the first month while there were only two (2%) deaths in the internal fixation group (P < 0.001). At 1 year from operation, 11 patients (38%) from the hemiarthroplasty group and 17 patients (16%) from the internal fixation group died (P = 0.0072). The re-operation rate within 1 year was higher for the internal fixation group (n = 8; 7.2%) than the hemiarthroplasty group (n = 1; 3%). CONCLUSIONS There is significant increase in mortality when undisplaced intracapsular hip fractures are treated by hemiarthroplasty as compared to internal fixation and we would not recommend it for these fractures.

Abstract
There is no consensus as to whether osteosynthesis (OS) or hemiarthroplasty (HA) should be used as the primary treatment of displaced femoral-neck fracture. In a prospective matched-pair study, we compared 84 patients treated with OS with three screws and 84 patients treated with uncemented Austin-Moore HA focusing on functional parameters, reoperations and mortality. At 4 months after the fracture, functional recovery was not significantly different between the study groups. However, OS patients tended to have slightly better functional ability than HA patients, as more of them were able to walk out of doors (45.2% versus 39.2%), more were able to walk without walking aids (23.7% versus 16.7%), and more returned to live in their own homes (80%versus 72.9%). OS patients used slightly but not significantly less painkillers and had less hip pain than HA patients. OS patients had had 15.4% more reoperations by 4 months and 14.2% more by 1 year compared to the HA group. The 4-month and 1-year mortality rates of the study groups were of the same order. Functional recovery was slightly better after OS with three screws than after uncemented HA, although no significant differences were seen in a sample of this size. On the other hand, OS was associated with a higher reoperation rate.

Abstract
This study evaluated the relationship of the disposition and outcome of patients with displaced femoral neck fractures with the type of surgical treatment. From 1993 to 1996, 186 patients with displaced femoral neck fractures who were 65 years of age or older were treated at one hospital. One hundred and twenty fractures were treated with reduction and internal fixation; 66 were treated with arthroplasty. The time interval from fracture to death and to repeat surgery was significantly less for the internal fixation group than for the arthroplasty group. The possibility of nursing home residence is increased in patients who were treated with reduction and internal fixation compared with patients who were treated with arthroplasty.

Postoperative deep vein thrombosis prophylaxis: a retrospective analysis in 1000 consecutive hip fracture patients treated in a community hospital setting. JOURNAL OF THE SOUTHERN ORTHOPAEDIC ASSOCIATION 2003; 12:10-7.

Abstract
The occurrence of deep vein thrombosis (DVT) following cases of major trauma, in particular pelvic and hip fracture, has ranged from 36% to 60%, depending on the study quoted and the method of detection. The frequency of fatal pulmonary embolism (PE) has been reported as 0.5%-12.9% of the cases. A retrospective study of 1000 consecutive hip fracture patients in a community hospital setting reveals that 95% received a combination of mechanical and pharmacologic prophylaxis for prevention of DVT. Sixty-one patients were excluded for insufficient data, leaving 939 for analysis. There were 724 female patients with an average age of 83 years and 215 male patients with an average age of 78 years. Fifty-one patients (18.4%) received no prophylaxis in the eligible population. Three hundred eighty-seven patients (41.2%) received only aspirin as the pharmacologic agent for anticoagulation. Four hundred twenty-nine patients (45.6%) were treated with the low-molecular-weight heparin (LMWH), enoxaparin. Ten patients (1.1%) received heparin for anticoagulation and 17 patients (1.8%) were treated with warfarin. A total of 43 patients received a combination of therapies. Four hundred ninety-five of the patients used concomitant intermittent pneumatic compression in addition to pharmacologic prophylaxis. There were 15 perioperative deaths from all causes, including five cases of DVT two distal and three proximal). One distal DVT occurred prior to surgery. A second distal DVT and one fatal PE occurred in the aspirin group. The rates of minor bleeding complications in the aspirin group, the < 12-hour postoperative dosing of the enoxaparin group, and the 12 to 24-hour postoperative dosing of the enoxaparin group were 3.1%, 5.7%, and 2.8%, respectively. There were no major bleeds in the aspirin group and 0.9% in the enoxaparin group. The LMWH group also had two proximal DVTs but no PEs. The combination of a relatively short half-life, predictable pharmacokinetics, and favorable safety profile makes enoxaparin an excellent drug for use in hip fracture patients. Additional trials will be necessary to establish an optimal duration of prophylaxis in this population.

Abstract
We retrospectively reviewed a population database and a case series to compare the mortality of operative and nonoperative treatment of hip fractures in patients with severe comorbidity. Nonoperative treatment of hip fractures (bed rest or early weight bearing) was administered based on medical assessment of perioperative risk. Comparison of 30-day mortality was performed between the nonoperatively and operatively treated groups. We found that of 50,235 of hip fractures that occurred between 1992 and 1998, 89.4% were treated operatively. Thirty-day mortality rate in the nonoperatively treated patients (18.8%) was higher than the rate in operatively treated patients (11.0%) (odds ratio 1.7 times, 95% confidence interval (CI) 1.6, 1.8). In the case series, of 62 elderly patients with severe comorbidity treated nonoperatively, 41 had bed rest/traction, while 21 were mobilized early. A group of operatively treated patients (n=108) was compared to nonoperatively treated patients. Mortality with nonoperative treatment was higher with bed rest (73%) compared to early mobilization (odds ratio 3.8, 95% CI 1.1-14.0). There was no significant difference in mortality between operatively treated patients (29%) and patients treated nonoperatively with immediate mobilization (19%). Bed rest was 2.5 times more likely to be associated with mortality compared to operative treatment (95% CI 1.1-5.5).

Abstract
The objective was to assess mortality and ambulatory ability for elderly patients over 90 years of age with femoral neck fractures treated surgically. From January 1998 to March 1999, 60 patients aged over 80 years were chosen for the study. The patients had a mean age of 87.1 years. The mean follow-up period was 12.9 months. The patients were classified into three groups according to age: group A (80-84 years old), group B (85-89 years old) and group C (over 90 years old). The rates of recovered postoperative walking ability were 72.2% (13/18) of group A, 65.2% (15/23) of group B and 84.2% (16/19) of group C. These patients were followed up until death or for at least one year. The overall mortality rates were 11.1% (2/18) of group A, 17.4% (4/23) of group B and 10.5% (2/19) of group C.

Abstract
We followed prospectively 295 patients with trochanteric fractures treated with the proximal femoral nail. The average age of the patients was 80 years and three out of four were female. The most frequent fracture type was A2 (59%). Clinical and radiographic controls were performed at 1, 3 and 6 months. There were technical complications during the operation in 12% of the cases, complications in the immediate postoperative period in 27% and late complications were detected in 4% of patients. Previous walking ability was recovered by 71%. The surgical technique is not complex, the number of complications recorded was acceptable and the overall results obtained are comparable with other fracture systems.

Abstract
BACKGROUNDS AND AIMS There are no randomised trials comparing internal fixation and hemiarthroplasty for a displaced intracapsular femoral neck fracture in relation to mental state. MATERIAL AND METHODS To establish what should be the treatment of first choice, a prospective randomised clinical study was performed on 60 demented patients with displaced intracapsular femoral neck fractures, comparing internal fixation (n = 31) with hemiarthroplasty (n = 29). RESULTS There was no significant difference in the mortality rate of both groups. Hemiarthroplasty was associated with significantly more loss of blood and more wound complications. Reoperation for secondary displacement of the fracture after internal fixation occurred in four patients. Although not-statistically significant, failure of internal fixation seemed to be higher after an inadequate osteosynthesis. CONCLUSION Postoperative mortality is high and the chance of successful rehabilitation very small for both types of treatment in this group of patients. In our opinion, demented patients should not be treated with a major surgical procedure like hemiarthroplasty. Internal fixation should be considered the treatment of choice, because it is a smaller operation than prosthetic replacement, with less morbidity. If adequate reduction can not be achieved, a primary hemiarthroplasty should be performed.

Abstract
OBJECTIVE To assess outcome after hip fracture in patients ninety years of age and older, as compared with a population of the same age and sex in the United States and younger patients with hip fractures. DESIGN Prospective, consecutive. SETTING University teaching hospital. METHODS Eight hundred fifty community-dwelling elderly people who sustained an operatively treated hip fracture were prospectively followed up. MAIN OUTCOME MEASUREMENTS The outcomes examined in this study were the patients' in-hospital mortality and postoperative complication rates, hospital length of stay, discharge status, mortality rate, place of residence, ambulatory ability, and independence in basic and instrumental activities of daily living twelve months after surgery. RESULTS AND CONCLUSIONS The mean patient age was 79.7 years (range 65 to 105 years). Seventy-six (8.9 percent) patients were ninety years of age and older. Patients who were ninety years of age and older had significantly longer mean hospital lengths of stay than younger individuals (p = 0.01). People ninety years of age and older were more likely to die during the hospital stay (p = 0.001) and within one year of surgery (p = 0.001). Patients who were ninety years of age and older were more likely to have a decrease in their basic activities of daily living status (p = 0.03) and ambulation level (p = 0.01). Younger individuals had a higher standard mortality ratio (1.48) than did patients who were ninety years of age and older (1.24). Being ninety years of age and older was not predictive of having a postoperative complication, of being placed in a skilled nursing facility at discharge or at one-year follow-up, or recovering of prefracture independence in instrumental activities of daily living.

Abstract
PURPOSE OF THE STUDY The purpose of this study was to highlight factors influencing vital and functional prognosis at 2.5 years of elderly people being treated for a proximal femoral fracture. MATERIAL The study was based on 78 patients more than 75 years old admitted to the orthopedic department for emergency treatment. After post-operative care, patients were transferred to a geriatric readaptation unit. The average patient age at the time of surgery was 85 years. METHODS This was a retrospective study. Survival graphs were established for the entire population as well as for the sub-populations characterized by a studied parameter. Mortality factors were compared via a univariable analysis. A multivariable logistical regression analysis isolated the factors explaining mortality at 12, 18, and 30 months and survival at 30 months, as well as factors explaining functional prognosis at 1 year. RESULTS The overall mortality rate was 41 per cent, 48.5 per cent of deaths occur within the first year. Factors which are harmful for vital prognosis are the following: high degree of dependence before the fracture, the existence of a neuropsychiatric pathology, and age factor (more than 85 years). 61.5 per cent of surviving patients were independent for daily activities. 77 per cent of surviving patients lived in their usual place of residence. Factors which were harmful for functional prognosis were the following: type of the fall, symptomatic of an underlying pathological state, and existence of a neuropsychiatric pathology. Nutrition was also a predictive factor concerning the patient's out come. DISCUSSION The average age of the studied population was higher than in most studies in literature. The treatment is mainly based on hip arthroplasty. The group of patients of over 85 have the highest mortality rate. However, a better survival rate at 18 months has been observed for patients older than 90 years. The delay before surgical care was significantly negative if longer than 6 days. However, a delay of 3 to 6 days was not significantly harmful for survival. Within the studied population, the maximum autonomy gain was observed during the first 6 months. The type of non-accidental fall, symptomatic of an associated pathology, was a factor for functional prognosis which has not been often mentioned. So was the biological deficit of nutrition. Social status acted as an indicator of functional status evolution. CONCLUSION Therapeutic choices can only be guided by assessments of patients' vital and functional prognosis. A sophisticated or even expensive device should be demanded for patients with favorable prognosis. For patients with precarious functional and vital prognosis, priority should be given to less invasive techniques with immediate walking. The cost of the device should be correlated with patient's functional investment.

Abstract
OBJECTIVE To determine the relationship of surgical repair of acute hip fracture within 2 days of hospital admission, followed by more than 5 sessions per week of physical and occupational therapy (PT/OT), to outcomes after acute hip fracture. DESIGN Comparison of hip fracture outcomes via secondary analysis of data obtained by retrospective medical record review according to timing of surgical repair and frequency of PT/OT, adjusted for patient, medical care, and hospital characteristics. SAMPLE The study included the medical records of 1880 elderly Medicare recipients admitted from the community to 284 acute care hospitals in 5 states during 1981 and 1982 or 1985 and 1986 with a primary diagnosis of acute hip fracture who underwent surgical repair and received PT/OT. INTERVENTIONS None. MAIN OUTCOME MEASURES The postoperative day when ambulation first occurred, the length of hospital stay, and return to the community. RESULTS Earlier surgical repair was associated with a shorter length of hospital stay (5 fewer days, P < .001) without a statistically significant increase in medical complications. High frequency PT/OT was associated with earlier ambulation (odds ratio [OR], 1.76; 95% confidence limits [CL], 1.50, 2.07). Patients who ambulated earlier [corrected] had shorter lengths of stay (6.5 fewer days, P < .001), were more likely to return to the community (OR, 1.45; 95% CL, 1.16, 1.81), and had better 6-month survival (OR, 2.8; 95% CL, 2.06, 3.88), and patients younger than 85 years had fewer in-hospital complications (11% vs 4%, P < .001). CONCLUSION Surgical repair within the first 2 days of hospitalization and more than 5 PT/OT sessions per week were associated with better health outcomes in a nationally representative sample of elderly patients with hip fracture.

Abstract
A total of 59 (13.5 per cent) of 437 patients with cervical hip fractures died within the first 3 months, compared with an expected mortality rate of 2.6 per cent in the comparable general population (P < 0.05). The average age at death was 86 years (range, 62-98). The 3-months mortality rate among patients admitted from institutions was 24/105 = 23 per cent compared with 35/332 = 10.5 per cent for patients admitted from their own homes (P < 0.05). The 3-months mortality rate for patients with Garden 1 + 2 fractures was 9.4 per cent compared with 14 per cent for Garden 3 + 4 (P < 0.05). This series seems to suggest that non-cemented hemi-arthroplasty may be associated with an increased 3-months mortality rate of 21 per cent compared with 13.9 per cent (P < 0.05) for patients with the same age distribution. This may be due to a relatively high deep-infection rate following non-cemented hemi-arthroplasty.

Abstract
A total of 427 patients with major chest trauma were treated in two major hospitals in Abu Dhabi, United Arab Emirates, during a 10-year period. In 64 of 426 patients, flail chest injury was the dominant factor among other injuries that were insignificant. Among 64 cases of flail chest injury, 25 were managed by internal fixation of ribs, whereas the remaining 38 were managed by endotracheal intubation and intermittent positive-pressure ventilation alone. Of the patients treated by internal fixation 80% (21/26) were weaned from the ventilator within an average of 1.3 days, whereas the remaining 20% (5/26) continued to need assisted ventilation for a longer duration; the total average duration of assisted ventilation for the whole group was 3.9 days. In comparison, among 38 patients with flail chest injury treated by endotracheal intubation and ventilation alone, the average duration of assisted ventilation was 15 days. In the group treated by internal fixation 11% (3/26) of the patients ultimately required a tracheotomy, whereas in the patients treated by intubation and ventilation alone tracheostomy was required in 37% (14/38) of the cases. In the group treated by internal fixation, chest infection was documented in 15% (4/26), septicemia in 4% (1/26), and barotrauma in 0%; in the other group these complications occurred in 50% (19/38), 24% (9/38), and 8% (3/38) of the cases, respectively. The mortality rate was 8% (2/26) in the surgically treated patients, whereas it was 29% (11/38) in the other group. All the deaths in both groups were ascribed to adult respiratory distress syndrome. Average stay in the intensive care unit was 9 days for the patients treated by internal fixation, whereas it was 21 days in the group treated by intubation and ventilation alone. The treatment of flail chest injury in our series by internal fixation resulted in speedy recovery, decreased complications, and better ultimate cosmetic and functional results and proved to be cost effective.

Abstract
Methods of meta-analysis, a technique for the combination of data from multiple sources, were applied to analyze 106 reports of the treatment of displaced fractures of the femoral neck. Two years or less after primary internal fixation of a displaced fracture of the femoral neck, a non-union had developed in 33 per cent of the patients and avascular necrosis, in 16 per cent. The rate of performance of a second operation within two years ranged from 20 to 36 per cent after internal fixation and from 6 to 18 per cent after hemiarthroplasty (relative risk, 2.6; 95 per cent confidence interval, 1.4 to 4.6). Conversion to an arthroplasty was the most common reoperation after internal fixation and accounted for about two-thirds of these procedures. The remaining one-third of the reoperations were for removal of the implant or revision of the internal fixation. For the patients who had had a hemiarthroplasty, the most common reoperations were conversion to a total hip replacement, removal or revision of the prosthesis, and débridement of the wound. Although we observed an increase in the rate of mortality at thirty days after primary hemiarthroplasty compared with that after primary internal fixation, the difference was not significant (p = 0.22) and did not persist beyond three months. The absolute difference in perioperative mortality between the two groups was small. An anterior operative approach for arthroplasty consistently was associated with a lower rate of mortality at two months than was a posterior approach. Some reports showed promising results after total hip replacement for displaced fractures of the femoral neck; however, randomized clinical trials are still needed to establish the value of this treatment.
