Clin Interv Aging 2023; 18:317-326. [PMID: 36883190 PMCID: PMC9985873 DOI: 10.2147/cia.s395012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Accepted: 02/17/2023] [Indexed: 03/03/2023] Open
Abstract
Aim The purpose of this study was to examine the incidence and cause of unplanned readmission after Surgically Treated Hip Fractures in Elderly Patients and identify the associated risk factors. Methods This study retrospectively collected the data on elderly patients who underwent hip fracture surgery at two institutions from January 2020 to December 2021, and identified those who were readmitted within 12 months postoperatively. Based on the presence or not of postoperative readmission, they were divided into readmission and non-readmission groups. Demographics, surgery-related variables, and laboratory parameters were compared between groups. The specific causes for documented readmission were collected and summarized. Multivariate logistic regression analysis was performed to identify the associated risk factors. Results There were 930 patients including 76 (8.2%) patients who were readmitted within 12 months postoperatively. Overall, cardiac and respiratory complications and new-onset fractures were the first three common causes of readmission, taking an overwhelming proportion of 53.9% (41/76). Over 60% (61.8%, 47/76) of readmissions occurred within 30 days after surgery, with medical complications taking a predominance (89.4%, 42/47). New-onset fractures accounted for a proportion of 18.4% (14/76), occurring at different time points; especially, at 90-365 days, it accounted for 44.4% (8/18). Multivariate analysis revealed that age ≥80 years (OR, 1.0, 95% CI, 1.0 to 1.1; P=0.032), preoperative albumin level ≤21.5 g/L (OR, 1.1, 95% CI, 1.0 to 1.2; P=0.009), the postoperative occurrence of DVT (OR, 4.2, 95% CI, 2.5 to 7.2; P=0.001), and local anesthesia (OR, 2.1, 95% CI, 1.1 to 4.0; P=0.029) were independent risk factors for unplanned readmissions. Conclusion This study identified several risk factors for unplanned readmissions after elderly hip fractures, and provided detailed information about unplanned readmissions.

Risk factors for a second nonsimultaneous hip fracture in a prospective cohort study. Arch Orthop Trauma Surg 2022; 142:2611-2617. [PMID: 34125250 DOI: 10.1007/s00402-021-03991-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Accepted: 06/09/2021] [Indexed: 12/17/2022]
Abstract
INTRODUCTION The risk factors for a second nonsimultaneous hip fracture are unclear, and in general, it is empirically assumed that they are similar to those associated with the first hip fracture. We aimed to determine the incidence of a second hip fracture and define the characteristics of the patients sustaining the event in a prospective cohort study in a Spanish population. MATERIALS AND METHODS We conducted a multicentric, prospective cohort study in a representative sample of 45 hospitals from 15 autonomic regions in Spain. In total, the study included 994 patients. One hundred and one patients presented a nonsimultaneous contralateral hip fracture, constituting the intervention group. The remaining 893 patients presenting with a hip fracture formed the control group. The main outcome measures of this study were sociodemographic characteristics of the patient, comorbid conditions, and baseline and postfracture clinical outcomes (inpatient complications and acute mortality). RESULTS The key fracture risk factors were a history of fragility fractures, the need for assistance when walking outdoors and a history of falls. There were no associations between the groups in any of the common fragility risk factors, including rheumatoid arthritis, secondary osteoporosis, or steroid consumption. The results showed that patients suffering a nonsimultaneous hip fracture had an increased risk of mortality after discharge compared with the control group. CONCLUSION A nonsimultaneous second hip fracture leads to a near-significant increase in four-month mortality. In our study, this fracture was associated with a history of falls, prior fragility fractures, and the need for a walking aid.

Abstract
Cementless bipolar hemiarthroplasty (BHA) recently gained popularity as a treatment for femur neck fracture (FNF), but there have been few studies comparing this with multiple screw fixation (MSF) in the elderly population. The purpose of this study is to compare (1) surgery-related parameters, (2) reoperation rate as a local complication, (3) in-hospital systemic complication rate, and (4) mortality rate at 1 year after MSF and cementless BHA in patients with FNF using nationwide data. Six-hundred sixty-six hips (aged ≥ 50 years) extracted from nationwide Hip Fracture Registry were included in this study (133 MSF and 533 cementless BHA). One hundred fifty-six hips were divided into nondisplaced FNF (Group A) and 510 into displaced FNF (Group B). We evaluated (1) surgery-related parameters (anesthesia type, time to surgery, operation time, estimated blood loss and volume of postoperative transfusion), (2) the rate of and reasons for reoperation, (3) the rate and type of in-hospital systemic complications and (4) one-year mortality rate after surgery. In Group A, MSF showed shorter operation time (p = 0.004) and lower incidence of in-hospital systemic complications (p = 0.003). In Group B, cementless BHA demonstrated lower reoperation rate than MSF (p < 0.001). In both Group A and B, cementless BHA was associated with higher estimated blood loss than MSF (p < 0.001). Based on findings in our study, MSF might be a more favorable option for nondisplaced FNF, whereas cementless BHA might be a better one for displaced FNF in patients older than fifty. Nevertheless, our nationwide study also showed that numbers of cementless BHAs were being performed for nondisplaced FNF even in teaching hospitals.

Abstract
BACKGROUND The aim of this study was to assess the prevalence of dementia as an underlying disease in elderly patients with hip fracture, to investigate the effect of dementia on postoperative mortality after surgery of hip fracture, and to analyze the differences in postoperative mortalities according to the severity of dementia through subgroup analysis. METHODS This study selected 2,346 elderly patients who were diagnosed with unilateral intertrochanteric or femoral neck fractures who underwent surgery between January 2004 and December 2018. The patients were classified into the non-dementia group (2,196 patients) and dementia group (150 patients; no-medication [66 patients] and medication [84 patients] subgroups). The cumulative crude mortality rate was calculated, and 30-day, 60-day, 3-month, 6-month, and 1-year mortality rates were compared between the groups. A univariate regression test was performed using age, sex, diagnosis, surgery type, and Charlson's comorbidity index (CCI), as these variables had P values of < 0.10. Multivariate regression analysis was performed to identify independent risk factors associated with mortality. RESULTS The 30-day, 60-day, 3-month, 6-month, and 1-year postoperative cumulative mortality rates were 1.8%, 3.8%, 5.6%, 8.9%, and 13.6%, respectively, in the non-dementia group, and 2%, 7.3%, 14%, 19.3%, and 24%, respectively, in the dementia group (P = 0.748, P = 0.048, P < 0.001, P < 0.001, and P = 0.001). The factors that affected the 1-year mortality were age (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.02-1.08; P < 0.001), sex (OR, 2.68; 95% CI, 2.07-3.47; P < 0.001), CCI (OR, 1.34; 95% CI, 1.23-1.47; P < 0.001), and dementia (OR, 1.70; 95% CI, 1.46-1.08; P = 0.016). In subgroup analysis, severity of dementia influenced the 6-month mortality (OR, 1.41; 95% CI, 1.70-2.01; P = 0.018), and 1-year mortality (OR, 1.30; 95% CI, 1.17-1.90; P = 0.027). CONCLUSION In elderly hip fracture patients, the comparison between patients with and without dementia revealed that dementia was an independent risk factor for mortality at a minimum of 1 year of follow-up, and the severity of dementia in hip fracture patients was a risk factor for mortality within 6 months and 1 year, postoperatively.

Abstract
OBJECTIVES An open-label, randomized trial was conducted to examine the effects of risedronate versus menopausal hormone therapy (MHT) in postmenopausal women with recent hip fracture. METHODS Among 1165 eligible women, 281 were recruited and randomly assigned to receive oral risedronate (35 mg/week) or percutaneous estradiol gel (1.5 mg/day) plus oral micronized progesterone (100 mg/day) for 4 years. The primary end point was recurrent fracture and the secondary end points were mortality and bone mineral density (BMD). RESULTS Kaplan-Meier analyses showed no significant differences in fracture recurrence and mortality between the two groups. The incidence of any new fracture per 100 person-years (PY) was 8.63 in the risedronate group and 12.86 in the MHT group (p = 0.180); that of clinical fracture was 4.75 and 6.99, respectively (p = 0.265); and that of asymptomatic vertebral fracture was 4.87 and 5.58, respectively (p = 0.764). The respective incidence of death per 100 PY was 3.58 and 4.40 (p = 0.503). BMD increased comparably at the lumbar spine in both groups. BMD at the total hip did not change in the risedronate group, but increased significantly by 2.8% in the MHT group. CONCLUSIONS MHT might not differ from risedronate in the prevention of secondary fractures and death among postmenopausal women with recent hip fracture.

Abstract
BACKGROUND There are few studies in the literature comparing the clinical outcomes and radiographic results of proximal femoral nail (PFN) and proximal femoral nail antirotation (PFNA) for pertrochanteric femoral fracture (PFF) in elderly patients.
AIM To evaluate both clinical and radiographic outcomes after fixation with PFN and PFNA in an elderly patient population.
METHODS One hundred fifty-eight patients older than 65 years with PFF who underwent fixation with either PFN or PFNA were included. Seventy-three patients underwent fixation with PFN, whereas 85 were fixed with PFNA. The mean follow-up was 2.4 years (range, 1-7 years). Clinical outcome was measured in terms of operation time, postoperative function at each follow-up visit, and mortality within one year. Radiographic evaluation included reduction quality after surgery, Cleveland Index, tip-apex distance (TAD), union rate, time to union, and sliding distance of the screw or blade. Complications including nonunion, screw cutout, infection, osteonecrosis of the femoral head, and implant breakage were also investigated.
RESULTS Postoperative function was more satisfactory in patients who underwent PFNA than in those who underwent PFN (P = 0.033). Radiologically, the sliding difference was greater in PFN than in PFNA patients (6.1 and 3.2 mm, respectively, P = 0.036). The rate of screw cutout was higher in the PFN group; eight for PFN (11.0%) and two for PFNA patients (2.4%, P = 0.027). There were no differences between the two groups in terms of operation time, mortality rate at one year after the operation, adequacy of reduction, Cleveland Index, TAD, union rate, time to union, nonunion, infection, osteonecrosis, or implant breakage.
CONCLUSION Elderly patients with PFF who underwent PFNA using a helical blade demonstrated better clinical and radiographic outcomes as measured by clinical score and sliding distance compared with patients who underwent PFN.

Reoperation rate, mortality and ambulatory ability after internal fixation versus hemiarthroplasty for unstable intertrochanteric fractures in elderly patients: a study on Korean Hip Fracture Registry. Arch Orthop Trauma Surg 2020; 140:1611-1618. [PMID: 31970505 DOI: 10.1007/s00402-020-03345-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2019] [Indexed: 01/08/2023]
Abstract
INTRODUCTION The treatment of unstable intertrochanteric fracture in elderly patients is challenging and how to treat these patients remains controversial. The purposes of this study were to compare (1) reoperation rate, (2) mortality and (3) the postoperative change of walking ability between patients undergoing internal fixation (IF) and those undergoing bipolar hemiarthroplasty (HA) due to this type of fracture based on the data from the Korean Hip Fracture Registry. MATERIALS AND METHODS Between July 2014 and June 2016, we extracted 623 unstable intertrochanteric fractures (616 patients aged ≥ 65 years) according to the classification of the Association for the Study of Internal Fixation-American Orthopaedic Trauma Association. Among the 564 patients, 396 were treated with IF (IF group) and 168 with bipolar HA (HA group). We compared the reoperation rate and mortality between IF group and HA group. In patients, who were followed up more than 2 years after the surgery, we compared the postoperative change of walking activity from ambulatory outdoors (Koval's grade 1, 2, 3) to housebound (Koval's grade 4, 5, 6). RESULTS The rate of reoperation was higher in the IF group (24/396, 6.1%) than in the HA (4/168, 2.4%) (p = 0.046). At the final follow-up, 79 (35.7%) of the 221 IF patients became housebound, whereas 21 (23.3%) of the 90 HA patients became housebound (p = 0.022). CONCLUSION This study showed HA was associated with lower rate of reoperation and lower decrement rate of walking ability compared to IF in elderly patients with unstable intertrochanteric fractures.

Abstract
OBJECTIVE To determine the factors affecting the amount of weight-bearing during gait training in the elderly patients who underwent internal fixation after femur or pelvic fractures and how well they performed the weight-bearing restriction as directed by the physiatrist. METHODS In this retrospective chart review study, we measured the amount of weight-bearing on the affected side in 50 patients undergoing internal fixation surgery and rehabilitation after femur or pelvic fracture using a force plate. Patients receiving non-weight-bearing or partial weight-bearing education were considered to perform weight-bearing restriction well when the amount of weight-bearing was <50 lb. Furthermore, regression analysis was performed to determine the effects of postoperative complications, age, cognitive function, and pain on weightbearing restriction. RESULTS Variables affecting the amount of weight-bearing were age (r=0.581, p<0.001), weight-bearing education type (r=0.671, p<0.001), manual muscle strength of hip flexion on the non-affected side (r=-0.296, p=0.037), hip abduction (r=-0.326, p=0.021), knee extension (r=-0.374, p=0.007), ankle plantar flexion (r=-0.374, p=0.008), right hand grip strength (r=-0.535, p<0.001), Korean version of Mini-Mental State Examination (r=-0.496, p<0.001), Clinical Dementia Rating (r=0.308, p=0.03), and pain visual analog scale scores (r=0.318, p=0.024). The significant predictor of the amount of weight-bearing among these variables was age (β=0.448, p=0.001). The weight-bearing restriction adherence rate was significantly lower, at 22%, for patients aged ≥65 years as compared to 73% for those <65 years. CONCLUSION Age was a major variable affecting the amount of weight-bearing. Compliance with weight-bearing restriction was significantly lower in patients aged ≥65 years than in patients <65 years.

Abstract
INTRODUCTION We designed a comparative study using elderly hip fracture patients with and without heart failure (HF). The purpose of this study was to assess 1) prevalence of HF, compare 2) early and late mortality after elderly hip fracture between HF and non-HF patients and to assess 3) risk factors of mortality after hip fractures in elderly patients with HF. In addition, we also investigated 4) whether there is a difference in mortality according to the severity of left ventricular (LV) systolic dysfunction classified by LV ejection fraction (EF) in HF patients through subgroup analysis. METHODS This study included 1992 patients (1992 hips) who were diagnosed as having unilateral femoral neck or intertrochanteric fractures and who underwent surgery at two hospitals between January 2004 and June 2018. The patients were categorized into a non-HF group (1782 patients) and a HF group (210 patients; mild [119 patients] and moderate-to- severe HF subgroups [91 patients]). The cumulative crude mortality rate was calculated, and 30-day, 60-day, 3-month, 6-month, and 1-year mortality rates were compared between the non-HF and HF. Logistic regression analysis was conducted to identify independent factors associated with mortality. RESULTS Of 1992 patients, 210 (10.5%) patients were diagnosed with HF. The 30-day, 60-day, 3-month, 6-month, and 1-year postoperative cumulative mortality rates were respectively 1.6%, 3.6%, 5.1%, 8.4%, and 12.9% in the non-HF group, and 5.7%, 9.5%, 12.4%, 17.1%, and 25.2% in the HF group (p ≤ 0.001). The factors that affected 1-year mortality were sex (OR, 2.10; 95% CI, 1.62-2.72; p < 0.001) and age (OR, 1.04; 95% CI, 1.02-1.06; p < 0.001) and presence of HF (OR, 1.62; 95% CI, 1.45-1.86; p = 0.005). In subgroup analysis, the factors that affected 30-day mortality were only moderate-to-severe HF (OR, 4.01; 95% CI, 1.10-8.78; p = 0.009). CONCLUSIONS In elderly patients with hip fracture, the comparison between the HF and non-HF patients revealed that HF was an independent factor of mortality at a minimum of 1-year follow-up, and severity of LV systolic dysfunction classified by LVEF in patients with hip fracture was also a risk factor of 30-day mortality.

Abstract
INTRODUCTION When locking intramedullary nails, inserting the distal interlocking screw accurately and quickly with less radiation exposure is very important. The purpose of this randomized control study was to compare radiation exposure and accuracy of distal locking screws between free-hand fluoroscopic guidance and the use of a distal targeting system (DTS). MATERIALS AND METHODS Inclusion criteria of this study were patients older than 60 years who need an intramedullary nailing due to unstable intertrochanteric and subtrochanteric fracture. The primary outcome was the attempt numbers of image intensifier during the insertion of distal locking screws. Secondary outcomes were operative time and angles between distal locking screws and nail. RESULTS A total of 36 patients participated in the study. Eighteen patients using free-hand fluoroscopic guidance were assigned to Group I while 18 patients using DTS were assigned to Group II. The number of attempts of image intensifier during distal screw insertion (57.3 ± 31.42 vs. 11.5 ± 7.41, p < 0.001), ratio of attempt number for distal screws to the total attempts (0.33 ± 0.21 vs. 0.12 ± 0.08, p = 0.001), the number of hand exposure to image intensifier directly (75.0 ± 29.55 vs. 13.5 ± 19.07, p < 0.001), and the time of radiation exposure during distal screws insertion (42.57 ± 2.42 s vs. 12.72 ± 8.10 s, p < 0.001) were significantly lower in Group II compared to those in Group I. And, operation time (96.3 min ± 18.94 vs. 76.1 min ± 14.10, p < 0.001) was also statistically significantly lower in Group II. Both distal locking screws were significantly closer to perpendicular direction to the nail in Group II. CONCLUSION The attempt number of image intensifier during the insertion of two distal locking screws was significantly reduced with DTS compared with that with free hand fluoroscopic guidance. Angle between distal locking screws and nail was also more accurate using DTS.

Abstract
PURPOSE Studies on the incidence and mortality of refractures after primary osteoporotic fracture are limited by the relatively rare incidence of such refractures and small sample sizes. The objectives of this research were: 1) to determine the incidence of osteoporotic refractures and fracture locations and 2) to assess mortality rates associated with osteoporotic refracture over a median follow up of 3 years using nationwide claim database. MATERIALS AND METHODS Patients over 50 years of age who had an osteoporotic fracture that was confirmed operationally were enrolled. Refracture was defined as that after 6 months of an untreated period. Mortality rate was calculated using the Charlson comorbidity index and was analyzed using Cox proportional hazards regression analysis. RESULTS A total of 18956 first-time instances of osteoporotic fracture were reported between 2007 and 2012 after a median follow up of 3.1 years (range, 1 to 7 years). Among 18956 patients, 2941 (15.50%) experienced refracture. After follow up for 1 year, cumulative mortality rates for re-fracture and non-refracture groups were 9.1% and 7.2%, respectively. After adjusting for covriates, mortality rate was 1.2 times greater in patients with re-fracture than in patients without re-fracture over a median follow up of 3 years (hazard ratio: 1.20, 95% confidence interval: 1.08-1.34, p<0.001). CONCLUSION The incidence of osteoporotic re-fracture in this nationwide study was 15.5%, and the mortality rate of re-fracture patients was 1.2 times higher than that of non-refracture patients over a median follow up of 3 years.

Kim JW, Kim DH, Jang EC, Lee YK, Koo KH, Ha YC. Mortality and its risk factors in nonagenarians after hip fractures. J Orthop Sci 2019; 24:850-854. [PMID: 30904205 DOI: 10.1016/j.jos.2019.02.019] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Revised: 01/29/2019] [Accepted: 02/04/2019] [Indexed: 01/22/2023]
Abstract
BACKGROUND The purpose of this study was to assess mortality with a minimum of 2-year follow-up, related risk factors for mortality, and functional outcomes after surgical interventions in nonagenarian patients with hip fractures at the latest follow up. METHODS Between June 2003 and November 2015, 260 nonagenarians (271 hips) with femoral neck and intertrochanteric fractures were included in this retrospective study. Cumulative mortality using the Kaplan-Meier method and risk factors for mortality using Cox proportional-hazards regression model were estimated. As functional outcome, ambulatory ability was assessed before injury and at the latest follow-up. RESULTS Six-teen patients (16 hips) were lost to follow-up. The mean age at the time of surgery was 92.2 years (range 90-108 years). Mortality rates were 23.4% (57 of 244 patients) at 1 year and 40.6% (99 of 244 patients) at 2 years. Both genders had elevated standardized mortality ratio at 2-year post-fracture compared to that a 1-year post fracture. Multivariate analysis showed that American Society of Anesthesiologists (OR, 1.371; 95% CI, 1.021-1.843; P = 0.036) and time interval from trauma to operation (OR, 1.043; 95% CI, 1.002-1.086; P = 0.039) were significantly associated with risk of mortality. Of 58 patients alive, 13 patients (22.4%) had the same ambulatory ability before and after injury. CONCLUSIONS This study demonstrates that mortality is higher in nonagenarians with hip fracture. Risk factors for mortality in nonagenarians with hip fracture are American Society of Anesthesiologists and time interval from trauma to operation. And, nonagenarians with hip fractures have lower rate of maintaining pre-injury ambulatory ability.
