Varus mal-alignment and residual displacement are associated with delayed union in subtrochanteric femur fracture- A retrospective observational study. J Orthop 2023; 46:64-69. [PMID: 37942221 PMCID: PMC10630759 DOI: 10.1016/j.jor.2023.10.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 10/04/2023] [Accepted: 10/27/2023] [Indexed: 11/10/2023] Open
Abstract
Background Subtrochanteric femoral (ST) fractures are associated with high rates of delayed and non-union. The aim of this study was to analyse the risk factors associated with delayed/non-union in ST fractures. Methods All patients with surgical stabilisation of ST fractures during the period 2014 to 2019 were identified in an electronic patient records database in two trauma centres. Exclusion criteria were incomplete clinical/radiological data, pathological fractures and loss to follow-up. Radiographs at about 6 months post-surgery were assessed for fracture union using Radiographic Union Score for Hip (RUSH). Fracture was deemed to be un-united if RUSH score was <18. CCD (caput-collum-diaphyseal) angle of operated and uninjured hip, residual displacement at fracture site and 3-point relationship was calculated on operative or immediate post-operative images in both groups. Student's t-test was used to compare CCD angle difference between operated and uninjured sides and the residual fracture displacement between delayed union and united fractures group. Chi-square test was used for 3-point relationship. Observational analysis was performed on implant failure rates including distal screw breakage. Results During the study period, there were total of 278 patients. 193 with inadequate data and 22 with pathological fractures were excluded. Advanced age and female sex had significantly higher rate of delayed union (p value of 0.043 and 0.003 respectively). Delayed union group (26) had a mean RUSH score of 14.1 and united group (37) had a mean RUSH score of 26.3 (p = 0.019). The mean CCD angle difference between operated and uninjured sides was -5.77° for delayed union and -2.33° for united fractures (p = 0.03). Residual displacement at fracture site showed statistically significant difference between delayed union and united fractures on anteroposterior and lateral views (p = 0.001 each). There was no statistical difference in 3-point relationship of implant in two groups (p = 0.775). 10 revision procedures were performed for implant failures. Distal screw failure (3 cases) was not a precursor for non-union in this study. Conclusion This study confirms varus alignment of hip and residual fracture displacement after fracture fixation of subtrochanteric fracture are surgeon associated significant risk factors for delayed union at 6 months. Fracture contact and alignment are key to reduce failures in these group of fractures. Among patient factors, advancing age and female sex predisposes to higher rate of delayed union.

Abstract
OBJECTIVE The objective of this study was to compare clinical outcomes of patients with trochanteric hip fractures treated with specific different cephalomedullary nail (CMN) designs. METHODS A scoping review of the English literature was performed. Inclusion criteria were studies comparing perioperative and postoperative outcomes of trochanteric hip fractures fixated by CMNs for one of the following CMN designs: short versus long nails, blade versus screw fixation, dual versus single lag screw fixation, and application of cement augmentation. Inclusion criteria consisted of human comparative clinical trials (randomized and observational). Exclusion criteria included noncomparative studies, studies comparing CMN with non-CMN devices or with arthroplasty, studies with less than 3 months follow-up, studies that did not provide relevant clinical outcome measures, biomechanical, finite element analyses, animal, or in vitro publications. Data regarding reoperations, peri-implant fractures, mechanical failure, nonunion, infection rates, and functional outcomes were reviewed. RESULTS Twenty-two studies met the inclusion criteria and formed the basis of this study. Failure of fixation rates and reoperation rates for each of the nail designs selected for evaluation is presented, in addition to specific outcome measures relevant to that nail design which was explored: peri-implant fracture-short versus long nails, and specific mechanism of failure-blade versus plate. CONCLUSIONS Decreased failure of fixation and reoperations rates were found for integrated dual lag screw fixation. Similar fixation failure and reoperation rates were found for the long versus short nails and for blade versus screw fixation. LEVEL OF EVIDENCE Diagnostic, Level IV.

Risk factors for cut-out in intertrochanteric fractures treated with proximal femoral nail of double proximal screw design. J Clin Orthop Trauma 2022; 28:101832. [PMID: 35371917 PMCID: PMC8966204 DOI: 10.1016/j.jcot.2022.101832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 03/09/2022] [Accepted: 03/15/2022] [Indexed: 11/24/2022] Open
Abstract
Background Intertrochanteric femoral fractures (IFF) are often seen in the elderly after a simple fall because of osteoporosis, and treatment is generally provided with proximal femoral nail (PFN). The complication of cut-out, which can develop as a result of PFN treatment of IFF, is a significant cause of morbidity. The aim of this study was to examine the risk factors for cut-out in cases treated with double proximal screw design nail (DPSDN). Methods A retrospective examination was made of patients aged> 70 years, who were operated on for IFF using DPSDN between January 2018 and December 2020. A record was made of the potential risk factors of age, gender, osteoporosis level (Singh Osteoporosis Index), fracture classification (AO/OTA classification), reduction quality, tip-apex distance(calTAD), and proximal screw placement values. Using logistic regression analysis, it was attempted to determine predictive factors for cut-out complication in cases operated on with DPSDN. Results With 219 cases included in the study, two groups were formed as cut-out and non-cut-out. Reduction quality, calTAD, and proximal screw placement were seen to be risk factors for cut-out. According to the univariate logistic regression analysis, the cut-out risk was 57.917-fold greater in those with "poor" reduction quality compared to those with "good" reduction quality, the risk was 17-fold greater in those with "superior"screw placement compared to "central" placement (p < 0.001), and 9.24-fold greater in those with "anterior" placement compared to "central" placement (p < 0.001). The cutoff value for calTAD for the diagnosis of cut-out was found to be > 25.5 mm (p = 0.026). Conclusion The results of this study demonstrated that the most important risk factors in the use of DPSDN are reduction quality, calTAD and proximal screw placement,. It was also concluded that just as in implants designed with a single screw, there is an increased risk when calTAD is > 25 mm.

Abstract
OBJECTIVE to conduct a systematic review with consequent meta-analysis evaluating the best treatment for Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) 31A1-A3 trochanteric fractures when comparing the sliding hip screw (SHS) to the intramedullary nail (IMN). The outcomes used for comparison are major complications (in total, as well as nonunion and infection specifically), mortality rates, functional outcomes and patient-reported outcome measures (PROM). MATERIALS AND METHODS Search strings for the Cochrane Library, CINAHL, Medline and Embase databases were developed with the help of a scientific librarian. Two authors screened the studies from the search string independently using Covidence.org and data extraction was performed similarly. Quality assessment was performed using the Cochrane Risk of Bias tool for randomised trials (ROB2) for RCT studies, and Cochrane Risk of Bias in Non-Randomised Studies - of Interventions (ROBINS-I) for non-RCT studies. Meta-analyses were performed using Log Risk Ratio as the primary effect estimate. RESULTS Of the 2,051 studies screened by the two authors, six RCTs and six non-RCTs were included in this meta-analysis, with a total of 10,402 patients. The results indicated no significant differences in total major complications, nonunion, infection or mortality between SHS and IMN treatments for AO/OTA 31A1, 31A2 and 31A3 trochanteric fractures. Due to a lack of compatible data, we were unable to perform a meta-analysis on function scores and PROM. However, there are trends that favour IMN for 31A1 and 31A2 fractures. CONCLUSION No significant difference between SHS and IMN was found in the meta-analysis in any of the examined AO/OTA fracture subtypes in terms of primary and secondary outcomes. When assessing function scores and PROM, we found trends favouring IMN for 31A1 and 31A2 fractures that should be explored further.

Abstract
INTRODUCTION The purpose of this study was to compare the role of the various surgical modalities ie, Hemiarthroplasty (HA), Dynamic Hip Screw (DHS), Cephalo-medullary nail (CMN) in the management of intertrochanteric fractures in elder patients with comparison of the results and assessment of the complications encountered with each method. METHODS Total 105 adult patients having intertrochanteric fractures managed during July 2013 to December 2018 at tertiary trauma care centre and followed for minimum 12 months were included in the study. Patients were divided into three groups. Primary hemiarthroplasty was done in 35 patients (group A) while DHS and PFN was done in 35 patients each in group B and group C respectively. Functional evaluation was done using Modified Harris Hip score (HHS) at different intervals while ambulatory function was measured using the Parker Mobility Score. RESULTS The mean age of patients was 72.14±2.9 years. Mean operative time and blood loss in group A was significantly higher than the other two groups. Hemiarthroplasty group could ambulate earlier than DHS/PFN group. Mean HHS at final follow up was 85.40±7 in group A while in group B and group C these values were 76.36±16.45 and 86.85±10.52 respectively. HHS was significantly higher (P, 0.01) in hemiarthroplasty group in comparison to DHS group. Post-operative complications were comparable in all the groups. CONCLUSION We support the use of hemiarthroplasty for unstable intertrochanteric fracture in elderly patients with lesser failure rates, early mobilization and better functional outcomes. Early mobilization and less hospital stay should be the goal of every surgical procedure in the elder population.

Abstract
BACKGROUND Hip fractures are a major healthcare problem, presenting a challenge and burden to individuals and healthcare systems. The number of hip fractures globally is rising. The majority of extracapsular hip fractures are treated surgically. OBJECTIVES To assess the relative effects (benefits and harms) of all surgical treatments used in the management of extracapsular hip fractures in older adults, using a network meta-analysis of randomised trials, and to generate a hierarchy of interventions according to their outcomes. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Web of Science and five other databases in July 2020. SELECTION CRITERIA We included randomised controlled trials (RCTs) and quasi-RCTs comparing different treatments for fragility extracapsular hip fractures in older adults. We included internal and external fixation, arthroplasties and non-operative treatment. We excluded studies of hip fractures with specific pathologies other than osteoporosis or resulting from high-energy trauma. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion. One review author completed data extraction which was checked by a second review author. We collected data for three outcomes at different time points: mortality and health-related quality of life (HRQoL) - both reported within 4 months, at 12 months and after 24 months of surgery, and unplanned return to theatre (at end of study follow-up). We performed a network meta-analysis (NMA) with Stata software, using frequentist methods, and calculated the differences between treatments using risk ratios (RRs) and standardised mean differences (SMDs) and their corresponding 95% confidence intervals (CIs). We also performed direct comparisons using the same codes. MAIN RESULTS We included 184 studies (160 RCTs and 24 quasi-RCTs) with 26,073 participants with 26,086 extracapsular hip fractures in the review. The mean age in most studies ranged from 60 to 93 years, and 69% were women. After discussion with clinical experts, we selected nine nodes that represented the best balance between clinical plausibility and efficiency of the networks: fixed angle plate (dynamic and static), cephalomedullary nail (short and long), condylocephalic nail, external fixation, hemiarthroplasty, total hip arthroplasty (THA) and non-operative treatment. Seventy-three studies (with 11,126 participants) with data for at least two of these treatments contributed to the NMA. We selected the dynamic fixed angle plate as a reference treatment against which other treatments were compared. This was a common treatment in the networks, providing a clinically appropriate comparison. We downgraded the certainty of the evidence for serious and very serious risks of bias, and because some of the estimates included the possibility of transitivity owing to the proportion of stable and unstable fractures between treatment comparisons. We also downgraded if we noted evidence of inconsistency in direct or indirect estimates from which the network estimate was derived. Most estimates included the possibility of benefits and harms, and we downgraded the evidence for these treatments for imprecision. Overall, 20.2% of participants who received the reference treatment had died by 12 months after surgery. We noted no evidence of any differences in mortality at this time point between the treatments compared. Effect estimates of all treatments included plausible benefits as well as harms. Short cephalomedullary nails had the narrowest confidence interval (CI), with 7 fewer deaths (26 fewer to 15 more) per 1000 participants, compared to the reference treatment (risk ratio (RR) 0.97, 95% CI 0.87 to 1.07). THA had the widest CI, with 62 fewer deaths (177 fewer to 610 more) per 1000 participants, compared to the reference treatment (RR 0.69, 95% CI 0.12 to 4.03). The certainty of the evidence for all treatments was low to very low. Although we ranked the treatments, this ranking should be interpreted cautiously because of the imprecision in all the network estimates for these treatments. Overall, 4.3% of participants who received the reference treatment had unplanned return to theatre. Compared to this treatment, we found very low-certainty evidence that 58 more participants (14 to 137 more) per 1000 participants returned to theatre if they were treated with a static fixed angle plate (RR 2.48, 95% CI 1.36 to 4.50), and 91 more participants (37 to 182 more) per 1000 participants returned to theatre if treated with a condylocephalic nail (RR 3.33, 95% CI 1.95 to 5.68). We also found that these treatments were ranked as having the highest probability of unplanned return to theatre. In the remaining treatments, we noted no evidence of any differences in unplanned return to theatre, with effect estimates including benefits as well as harms. The certainty of the evidence for these other treatments ranged from low to very low. We did not use GRADE to assess the certainty of the evidence for early mortality, but our findings were similar to those for 12-month mortality, with no evidence of any differences in treatments when compared to dynamic fixed angle plate. Very few studies reported HRQoL and we were unable to build networks from these studies and perform network meta-analysis. AUTHORS' CONCLUSIONS: Across the networks, we found that there was considerable variability in the ranking of each treatment such that there was no one outstanding, or subset of outstanding, superior treatments. However, static implants such as condylocephalic nails and static fixed angle plates did yield a higher risk of unplanned return to theatre. We had insufficient evidence to determine the effects of any treatments on HRQoL, and this review includes data for only two outcomes. More detailed pairwise comparisons of some of the included treatments are reported in other Cochrane Reviews in this series. Short cephalomedullary nails versus dynamic fixed angle plates contributed the most evidence to each network, and our findings indicate that there may be no difference between these treatments. These data included people with both stable and unstable extracapsular fractures. At this time, there are too few studies to draw any conclusions regarding the benefits or harms of arthroplasty or external fixation for extracapsular fracture in older adults. Future research could focus on the benefits and harms of arthroplasty interventions compared with internal fixation using a dynamic implant.

Abstract
BACKGROUND Hip fractures are a major healthcare problem, presenting a substantial 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. Most hip fractures are treated surgically. This Cochrane Review evaluates evidence for implants used to treat extracapsular hip fractures. OBJECTIVES To assess the relative effects of cephalomedullary nails versus extramedullary fixation implants for treating extracapsular hip fractures in older adults. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Web of Science, the Cochrane Database of Systematic Reviews, Epistemonikos, ProQuest Dissertations & Theses, and the 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 cephalomedullary nails with extramedullary implants for treating fragility extracapsular hip fractures in older adults. We excluded studies in which all or most fractures were caused by a high-energy trauma or specific pathologies other than osteoporosis. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We collected data for seven critical outcomes: performance of activities of daily living (ADL), delirium, functional status, health-related quality of life, mobility, mortality (reported within four months of surgery as 'early mortality'; and reported from four months onwards, with priority given to data at 12 months, as '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 76 studies (66 RCTs, 10 quasi-RCTs) with a total of 10,979 participants with 10,988 extracapsular hip fractures. The mean ages of participants in the studies ranged from 54 to 85 years; 72% were women. Seventeen studies included unstable trochanteric fractures; three included stable trochanteric fractures only; one included only subtrochanteric fractures; and other studies included a mix of fracture types. More than half of the studies were conducted before 2010. Owing to limitations in the quality of reporting, we could not easily judge whether care pathways in these older studies were comparable to current standards of care. We downgraded the certainty of the outcomes because of high or unclear risk of bias; imprecision (when data were available from insufficient numbers of participants or the confidence interval (CI) was wide); and inconsistency (when we noted substantial levels of statistical heterogeneity or differences between findings when outcomes were reported using other measurement tools). There is probably little or no difference between cephalomedullary nails and extramedullary implants in terms of mortality within four months of surgery (risk ratio (RR) 0.96, 95% CI 0.79 to 1.18; 30 studies, 4603 participants) and at 12 months (RR 0.99, 95% CI 0.90 to 1.08; 47 studies, 7618 participants); this evidence was assessed to be of moderate certainty. We found low-certainty evidence for differences in unplanned return to theatre but this was imprecise and included clinically relevant benefits and harms (RR 1.15, 95% CI 0.89 to 1.50; 50 studies, 8398 participants). The effect estimate for functional status at four months also included clinically relevant benefits and harms; this evidence was derived from only two small studies and was imprecise (standardised mean difference (SMD) 0.02, 95% CI -0.27 to 0.30; 188 participants; low-certainty evidence). Similarly, the estimate for delirium was imprecise (RR 1.22, 95% CI 0.67 to 2.22; 5 studies, 1310 participants; low-certainty evidence). Mobility at four months was reported using different measures (such as the number of people with independent mobility or scores on a mobility scale); findings were not consistent between these measures and we could not be certain of the evidence for this outcome. We were also uncertain of the findings for performance in ADL at four months; we did not pool the data from four studies because of substantial heterogeneity. We found no data for health-related quality of life at four months. Using a cephalomedullary nail in preference to an extramedullary device saves one superficial infection per 303 patients (RR 0.71, 95% CI 0.53 to 0.96; 35 studies, 5087 participants; moderate-certainty evidence) and leads to fewer non-unions (RR 0.55, 95% CI 0.32 to 0.96; 40 studies, 4959 participants; moderate-certainty evidence). However, the risk of intraoperative implant-related fractures was greater with cephalomedullary nails (RR 2.94, 95% CI 1.65 to 5.24; 35 studies, 4872 participants; moderate-certainty evidence), as was the risk of later fractures (RR 3.62, 95% CI 2.07 to 6.33; 46 studies, 7021 participants; moderate-certainty evidence). Cephalomedullary nails caused one additional implant-related fracture per 67 participants. We noted no evidence of a difference in other adverse events related or unrelated to the implant, fracture or both. Subgroup analyses provided no evidence of differences between the length of cephalomedullary nail used, the stability of the fracture, or between newer and older designs of cephalomedullary nail. AUTHORS' CONCLUSIONS Extramedullary devices, most commonly the sliding hip screw, yield very similar functional outcomes to cephalomedullary devices in the management of extracapsular fragility hip fractures. There is a reduced risk of infection and non-union with cephalomedullary nails, however there is an increased risk of implant-related fracture that is not attenuated with newer designs. Few studies considered patient-relevant outcomes such as performance of activities of daily living, health-related quality of life, mobility, or delirium. This emphasises the need to include the core outcome set for hip fracture in future RCTs.

Abstract
AIMS This study evaluated variation in the surgical treatment of stable (A1) and unstable (A2) trochanteric hip fractures among an international group of orthopaedic surgeons, and determined the influence of patient, fracture, and surgeon characteristics on choice of implant (intramedullary nailing (IMN) versus sliding hip screw (SHS)). METHODS A total of 128 orthopaedic surgeons in the Science of Variation Group evaluated radiographs of 30 patients with Type A1 and A2 trochanteric hip fractures and indicated their preferred treatment: IMN or SHS. The management of Type A3 (reverse obliquity) trochanteric fractures was not evaluated. Agreement between surgeons was calculated using multirater kappa. Multivariate logistic regression models were used to assess whether patient, fracture, and surgeon characteristics were independently associated with choice of implant. RESULTS The overall agreement between surgeons on implant choice was fair (kappa = 0.27 (95% confidence interval (CI) 0.25 to 0.28)). Factors associated with preference for IMN included USA compared to Europe or the UK (Europe odds ratio (OR) 0.56 (95% CI 0.47 to 0.67); UK OR 0.16 (95% CI 0.12 to 0.22); p < 0.001); exposure to IMN only during training compared to surgeons that were exposed to both (only IMN during training OR 2.6 (95% CI 2.0 to 3.4); p < 0.001); and A2 compared to A1 fractures (Type A2 OR 10 (95% CI 8.4 to 12); p < 0.001). CONCLUSION In an international cohort of orthopaedic surgeons, there was a large variation in implant preference for patients with A1 and A2 trochanteric fractures. This is due to surgeon bias (country of practice and aspects of training). The observation that surgeons favoured the more expensive implant (IMN) in the absence of convincing evidence of its superiority suggests that surgeon de-biasing strategies may be a useful focus for optimizing patient outcomes and promoting value-based healthcare.

Abstract
BACKGROUND Normally taking the surgery is the standard treatment, between sliding hip screw (SHS) and utilizing proximal femoral nail antirotation (PFNA) for intramedullary fixation, it is still not certain which one work better for this type of fracture. Our purpose for this study was to determine the optimum choice of implant for a patient with an unstable intertrochanteric fracture. METHODS In our hospital, a reflective analysis was conducted of all unstable intertrochanteric fractures treated with either a SHS or PFNA fixation between February 2015 and February 2018. The rules of choosing patients were the following: older age of more than 60, unstable intertrochanteric fractures, and willingness to take clinical and radiographic follow-up researches for over 12 months. In this case, patients bearing former hip surgery at any side were removed from the candidates. Demographic characteristics collected effective information including gender, date of operation, and other relevant information. Postoperative outcome measures included operation time, total blood loss amount, validated mobility score, surgery-related syndrome, and tip-apex length. The patients were re-examined at three time periods: 3 weeks, 3 months, and 1 year. The result of P < .05 was considered to be statistically significant. RESULTS We were able to directly compare the outcomes of PFNA vs SHS techniques and might reveal a better technique in treatment of an unstable intertrochanteric fracture. TRIAL REGISTRATION This study protocol has been registered in Research Registry (researchregistry6057).

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
Continuing controversy exists for the choice of implant for treating A3 trochanteric hip fractures so we undertook a systematic review of randomised controlled trials from the year 2000 onwards that have compared an intramedullary nail with an extramedullary fixation implant for the treatment of these fractures. Data on the occurrence of any fracture healing complications was extracted and the results combined to calculate Peto odd ratio. Nine studies involving 370 fractures were identified. Three studies involving 105 fractures compared an intramedullary nail with a static fixation (condylar, blade or locking plate). Plate fixation was associated with a fivefold increase risk of fracture healing complications (19/52(36.6%) versus 4/53(7.5%), odds ratio 0.14, 95% Confidence intervals 0.04-0.45). Six studies involving 265 fractures compared an intramedullary nail with a sliding hip screw. No statistically significant difference was found in the occurrence of facture healing complications between implants (13/137(9.5%) versus 11/128(8.6%) odds ratio 0.28, 95% Confidence intervals 0.50-2.80). Bases on the evidence to date from randomised trials, the use of fixed nail plates for surgical fixation of this type of fracture cannot be justified. Intramedullary nail fixation and the sliding hip screw have comparable fracture healing complication rates.

Abstract
PURPOSE The aim of this study was to investigate the incidence of Z-effect after dual lag screw intramedullary nailing systems and risk factors contributing to this effect. We hypothesized that long nails provide more neck strength due to a longer lever than short nails and are therefore less likely to develop a misbalance of a higher head compressive strength than neck compressive strength. METHODS In this retrospective cohort study 103 patients treated operatively with a dual lag screw intramedullary nailing device for (sub)trochanteric hip fracture were included. We analysed patient charts regarding patient and operation characteristics. Furthermore we conducted radiologic measurements within the 2-year follow-up period to investigate the quality of fracture fixation, implant failure and predictors for Z-effect. The re-operation risk was investigated with multivariate regression analysis. RESULTS The incidence of (reversed) Z-effect in this study was 9% (n = 80); 6 out of 7 Z-effects occurred in the short nail group, which was not significant. Patients who were treated with a long nail had a significant larger number of complications in comparison with the short nail group (median 2 vs 0.5, p = 0.001). The long nail group received more often erythrocytes blood transfusions (82% vs 31%, p < 0.01) and had a longer hospital stay (13 vs 21 days, p < 0.05). Migration of lag screws (p <0.05) and unstable fracture type (p < 0.05), were risk factors for re-operation. The re-operation rate within 2 year after surgery was 21%, of which one fourth was due to a Z-effect. CONCLUSION The nail length was not associated with the development of a Z-effect. Migration of lag screws after intramedullary nailing is common and a risk factor for re-operation.

Abstract
INTRODUCTION There are limited information and inconclusive results for dual head screw intramedullary hip nails for trochanteric fractures. Therefore, we performed a prospective study to evaluate the healing of fractures, and survival, function, and complications of patients operated with this implant. METHODS We prospectively studied 79 patients (61 women and 18 men; mean age: 84.7 years; range: 65-96 years) with a low-energy trochanteric fracture, treated with a dual head screw intramedullary hip nail from 2013 to 2016. The mean follow-up was 2.1 years (range: 1-3 years); seven patients were lost to follow up. This left 72 patients for further analysis. We evaluated the healing of fractures, and survival, function, and complications of patients. RESULTS Fracture healing was evident in 70 patients (97.2%) at 2-3 months postoperatively. One patient experienced cut-out and z-effect phenomenon of the head screws. Another patient experienced a periprosthetic femoral diaphysis fracture at the distal tip of the nail. A third patient experienced an acute postoperative superficial skin infection that was treated successfully with wound dressing changes and a course of antibiotics. Sixteen patients (22.2%) deceased within 12 months postoperatively. In the remaining patients, the Harris Hip Score (HHS) at 12 months postoperatively was excellent in 16 (28.6%), good in 23 (41.1%), fair in 10 (17.8%), and poor in 7 patients (12.5%). The function declined after the patients' fracture. Fair and poor results were related to age > 85 years, poor pre-fracture level of function, and AO/OTA-31-A3 fracture types. CONCLUSION The dual head screw intramedullary hip nail is associated with high healing and low complication rates for intertrochanteric fractures. The function of the patients is good or excellent in most cases; however, it declines, especially for those patients with age > 85 years, poor pre-fracture level of function, and AO/OTA-31-A3 fracture types.

Abstract
Background In treatment of unstable trochanteric fractures dynamic hip screw and Medoff sliding plate devices are designed to allow secondary fracture impaction, whereas intramedullary nails aim to maintain fracture alignment. Different treatment protocols are used by two similar Swedish regional emergency care hospitals. Dynamic hip screw is used for fractures considered as stable within the respective treatment protocol, whereas one treatment protocol (Medoff sliding plate/dynamic hip screw) uses biaxial Medoff sliding plate for unstable pertrochanteric fractures and uniaxial Medoff sliding plate for subtrochanteric fractures, the second (intramedullary nail/dynamic hip screw) uses intramedullary nail for subtrochanteric fractures and for pertrochanteric fractures with intertrochanteric comminution or subtrochanteric extension. All orthopedic surgeries are registered in a regional database. Methods All consecutive trochanteric fracture operations during 2011–2012 (n = 856) and subsequent technical reoperations (n = 40) were derived from the database. Reoperations were analysed and classified into the categories adjustment (percutaneous removal of the locking screw of the Medoff sliding plate or the intramedullary nail, followed by fracture healing) or minor, intermediate (reosteosynthesis) or major (hip joint replacement, Girdlestone or persistent nonunion) technical complications. Results The relative risk of intermediate or major technical complications was 4.2 (1.2–14) times higher in unstable pertrochanteric fractures and 4.6 (1.1–19) times higher in subtrochanteric fractures with treatment protocol: intramedullary nail/dynamic hip screw, compared to treatment protocol: Medoff sliding plate/dynamic hip screw. Overall rates of intermediate and major technical complications in unstable pertrochanteric and subtrochanteric fractures were with biaxial Medoff sliding plate 0.68%, with uniaxial Medoff sliding plate 1.4%, with dynamic hip screw 3.4% and with intramedullary nail 7.2%. Conclusions The treatment protocol based on use of biaxial Medoff sliding plate for unstable pertrochanteric and uniaxial Medoff sliding plate for subtrochanteric fractures reduced the risk of severe technical complications compared to using the treatment protocol based on dynamic hip screw and intramedullary nail.

Abstract
OBJECTIVE We assessed factors associated with cut-out after internal fixation of proximal femoral fractures using double lag screw nails. DESIGN Retrospective cohort study. SETTING A university hospital. PATIENTS AND METHODS Patients with non-pathological intertrochanteric femur fractures and a minumum 90days follow-up who underwent internal fixation with dual lag screw nails were included. Potential risk factors for lag screw cut-out investigated by our study were: age, gender, body mass index, comorbidities (American Society of Anesthesiologists [ASA] classification), type of fracture (AO/OTA classification), fracture stability, side, operation time, implant length, reduction quality, tip-apex distance (TAD), and lag screw configuration. Logistic regression was used to investigate potential predictors of screw cut-out. RESULTS Eighty-five of the 118 patients with hip fractures treated between February 2010 and November 2013 at our institution met the inclusion criteria for the study. Fifty-eight patients were female (68.2%), mean age was 77.4 (range: 50-95 years), mean follow up was 380days (range: 150days-2.5 years), and cut of was observed in 9 patients (10.5%). The following variables identified through univariate analysis with p<0.2 were included in multivariant logistic regression model: age, side, reduction quality, implant length, TAD and ASA score. Only TAD (p=0.003) was found to be significant in the multivariant model. CONCLUSIONS Our study confirmed that risk factors for cut-out with single-lag screw devices are also applicable to dual-lag screw implants. We found that TAD was a significant factor for cut-out in dual-lag screw implants. Thus, screw cut-out can be minimized by optimizing screw position.

Abstract
Aims The aim of this paper is to review the evidence relating to the anatomy of the proximal femur, the geometry of the fracture and the characteristics of implants and methods of fixation of intertrochanteric fractures of the hip. Materials and Methods Relevant papers were identified from appropriate clinical databases and a narrative review was undertaken. Results Stable, unstable, and subtrochanteric intertrochanteric fractures vary widely in their anatomical and biomechanical characteristics, as do the implants used for their fixation. The optimal choice of implant addresses the stability of the fracture and affects the outcome. Conclusion The treatment of intertrochanteric fractures of the hip has evolved along with changes in the design of the implants used to fix them, but there remains conflicting evidence to guide the choice of implant. We advocate fixation of 31A1 fractures with a sliding hip screw and all others with an intramedullary device. Cite this article: Bone Joint J 2017;99-B:128–33.

Abstract
INTRODUCTION Evaluation of the long-term performance of implants used in trauma surgery relies on post-marked clinical studies since no registry based implant assessment exists. The purpose of this study was to evaluate the evidence of performance of implants currently used for treating proximal femoral fractures (PFF) in Denmark. METHOD PubMed was searched for clinical studies on primary PFF with follow-up ≥12 months, reporting implant-related failure and evaluating one of following: DHS, CHS, HipLoc, Gamma3, IMHS, InterTan, PFN, PFNA or PTN. LIMITS English language and publication date after 1st of January 1990. RESULTS All studies were evidence level II or III. 30 publications for SHS were found: 13 of CHS, 15 of DHS and 2 of HipLoc. In total CHS was evaluated in 1110 patients (900 prospectively), DHS in 2486 (567 prospectively) and HipLoc in 251 (all prospectively). Fifty-four publications for nails were found: 13 of Gamma3, 7 of IMHS, 5 of InterTan, 10 of PFN, 24 of PFNA and 0 of PTN. In total Gamma3 was evaluated in 1088 patients (829 prospectively), IMHS in 1543 (210 prospectively), InterTan in 595 (585 prospectively), PFN in 716 (557 prospectively), PFNA in 1762 (1018 prospectively) and PTN in 0. CONCLUSIONS The clinical evidence behind the current implants used for proximal femoral fractures is weak considering the number of implants used worldwide. Sporadic evaluation is not sufficient to identify long term problems. A systematic post market surveillance of implants used for fracture treatment, preferable by a national register, is necessary in the future.

Abstract
Surgical management of hip fractures in elderly people is challenging and complications relating to surgery could be devastating. They often lead to reoperation and revision surgery and can be associated with significantly increased morbidity and mortality. The most common surgical complications after internal fixation of hip fractures include cut-out, nonunion, Z-effect/medial migration, periimplant failure and avascular necrosis. High quality surgical fixation is of outmost importance to avoid surgical complications. This article presents the aetiology, risk factors and incidence of perioperative and post-fracture fixation complications. Technical tips and tricks for a successful fixation as well as the contemporary evidence surrounding the augmentation of osteoporotic bone fixation in internal fixation of hip fractures are discussed.

Abstract
INTRODUCTION The Royal College of Surgeons of England (RCS) has issued guidance regarding the use of reoperation rates in the revalidation of UK-based orthopaedic surgeons. Currently, little has been published concerning acceptable rates of reoperation following primary surgical management of orthopaedic trauma, particularly with reference to revalidation. METHODS A retrospective review was conducted of patients undergoing clearly defined reoperations following primary surgical management of trauma between 1 January 2010 and 31 December 2011. A full case note review was undertaken to establish the demographics, clinical course and context of reoperation. A review of the imaging was performed to establish whether the procedure performed was in line with accepted trauma practice and whether the technical execution was acceptable. RESULTS A total of 3,688 patients underwent primary procedures within the time period studied while 70 (1.90%, 99% CI: 1.39-2.55) required an unplanned reoperation. Thirty-nine (56%) of these patients were male. The mean age of patients was 56 years (range: 18-98 years) and there was a median time to reoperation of 50 days (IQR: 13-154 days). Potentially avoidable reoperations occurred in 41 patients (58.6%, 99% CI: 43.2-72.6). This was largely due to technical errors (40 patients, 57.1%, 99% CI: 41.8-71.3), representing 1.11% (99% CI: 0.73-1.64) of the total trauma workload. Within RCS guidelines, 28-day reoperation rates for hip, wrist and ankle fractures were 1.4% (99% CI: 0.5-3.3), 3.5% (99% CI: 0.8%-12.1) and 1.86% (99% CI: 0.4-6.6) respectively. CONCLUSIONS We present novel work that has established baseline reoperation rates for index procedures required for revalidation of orthopaedic surgeons.
