Abstract
Pediatric femur fractures in children aged 5 to 11 years are typically classified as length-stable versus length-unstable. For length-stable fracture patterns, there is frequent consensus among pediatric orthopaedic specialists regarding the appropriateness of flexible intramedullary nails, submuscular plates (SMP), or lateral-entry rigid intramedullary nails (LE-RIMN). With length-unstable fracture patterns, however, the decision is more complex. Age, weight, fracture pattern, fracture location, surgical technique, surgeon experience, several implant-specific details, and additional factors are all important when choosing between flexible intramedullary nail, SMP, and LE-RIMN. These familiar methods of fixation may all be supported by conflicting and sometimes heterogeneous data. When planning to treat length-unstable fractures in young children, surgeons should understand evidence-based details associated with each implant and how each patient-specific scenario affects perioperative decisions.

Abstract
OBJECTIVES To investigate femoral intramedullary (IM) pressures during reamed antegrade nailing and to determine whether fracture level and/or complexity affect peak pressures. METHODS DESIGN Prospective, nonrandomized observational cohort. SETTING Single level I trauma center. PATIENT SELECTION CRITERIA Patients presenting with femur fractures (OTA/AO 31A3; 32A; 32B; 32C; 33A2; 33A3), requiring antegrade IM nail fixation, were included in this study. Excluded were minors and patients presenting with hemodynamic instability, a reduced level of consciousness and intoxication. Femurs were divided into thirds based on preoperative radiological measurements and allocated to 3 groups based on fracture location: Proximal (A), middle (B), and distal (C) third femur fractures. Fracture complexity was also documented. OUTCOME MEASURES AND COMPARISONS Peak IM pressures of proximal, middle, and distal third femoral fractures were compared during antegrade femoral IM nail fixation. RESULTS Twenty-two fractures in 21 patients were enrolled and treated over a 4-month period with a distribution of fracture locations of group A = 12, group B = 6, and group C = 4. Measured mean resting distal IM pressures were significantly higher ( P < 0.05) in proximal fractures (group A: 52.5 mm Hg) than in middle and distal third fractures (group B: 36.6 mm Hg and group C: 27.5 mm Hg). Greatest peak pressures were generated during the first ream in groups A and B, occurring distal to the fracture in all cases. Group A averaged 363.8 mm Hg (300-420), group B 174.2 mm Hg (160-200), and group C 98.8 mm Hg (90-100). There was a significant difference comparing group A with B and C combined ( P < 0.01) and group A with B ( P < 0.05) and C ( P < 0.05]) individually. Group A consisted of 6 comminuted and 6 simple fracture configurations. Mean peak pressures in these subgroups differed significantly: 329 mm Hg (300-370) versus 398 mm Hg (370-430), respectively ( P < 0.05). Complex fractures in study groups B and C did not have significantly different peak pressures compared with simple fractures ( P > 0.05). CONCLUSIONS Both the fracture location and comminution affect peak IM pressures during reamed antegrade femoral nailing. Proximal, simple fracture configurations resulted in significantly higher pressures when compared with more distal and comminuted fracture configurations. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
OBJECTIVES To assess if a suprapatellar (SP) approach, when compared with an infrapatellar (IP) approach, yielded less patient-reported anterior knee pain and higher patellofemoral joint function at 6 weeks and 12 months postoperatively, when treating tibial fractures with intramedullary nailing. METHODS DESIGN Prospective, parallel-group randomized control trial. SETTING Tertiary level 1 trauma care center, Brisbane, Australia. PATIENTS SELECTION CRITERIA Skeletally mature patients with an acute diaphyseal tibial fracture (AO/OTA 41A2/3, 42 A1-43A3) amenable to an intramedullary nailing were included. Exclusion criteria were periprosthetic fractures, nonunions, and presence of a contralateral injury that would restrict weight-bearing. OUTCOME MEASURES AND COMPARISONS Anterior knee pain through the visual analog scale (VAS) and patellofemoral function using the Kujala scale at 6 weeks and 12 months were compared between those treated with a SP and IP approach. RESULTS Ninety-five tibia fractures were included in the randomized trial, with complete follow-up data for 44 and 46 tibia fractures in the SP and IP groups, respectively. The SP cohort exhibited better patellofemoral knee function at both 6 weeks (Kajula 53.0 for SP vs. 43.2 for IP, P < 0.01) and 12 months (Kujala 92.0 for SP vs. 81.3 for IP, P < 0.01) postoperatively and a reduction in anterior knee pain at 12 months postoperatively (VAS 0.7 SP vs. 2.9 IP, P < 0.01). CONCLUSIONS This randomized trial demonstrated clinically meaningful differences in patellofemoral function, for a SP versus IP approach, with a greater than 10 point discrepancy in Kujala score at both 6 weeks and 12 months. In addition, there was a clinically important difference in VAS knee pain scores for patients at 12 months, but not at 6 weeks, postoperatively. These results contribute to the growing body of evidence demonstrating the functional and clinical benefits of the SP approach. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
INTRODUCTION Proximal femur fractures in elderly patients pose a common problem that requires surgical management. The main objective of this study was to compare the results of treatment by locked plate (LP) and by anterograde (AIN) or retrograde (RIN) intramedullary nailing. The secondary objective was to analyze the complications related to each group. The hypothesis of this study was that the radiological and clinical results of each group were comparable. MATERIALS AND METHODS The data of 438 patients from 8 centers were studied retrospectively with 365 LP and 69 cases of intramedullary nailing (49 AIN and 20 RIN). The groups were comparable in terms of mean age (75±2years), mean preoperative Parker score (5.3±0.5) and mean KOOS score (74±2). Most patients lived at home before their fracture [n=375 (86%)]. At follow-up, the joint range of motion, the KOOS and Parker scores, living premises, the time required to regain full weight-bearing, the time required for consolidation as well as the reduction alignment: frontal, sagittal, horizontal. RESULTS The average follow-up was: 79±2weeks (65 to 82). The functional and radiological results were comparable, although nailing allowed a faster return to weight-bearing (1±2weeks for nailing versus 7±2weeks for LP, p=0.048) and a better postoperative Parker score (5.5±0.5 for nailing versus 4.7±0.2 for LP, p=0.045). Rotational malalignment in femoral nailing was often in the direction of internal rotation, compared to the LP (p=0.045). Complications were comparable with the exception of mortality, which was more frequent for LP [22.5% in the LP group versus 13% in the nailing group (p=0.045)]. Complications were categorized as: mechanical complications 6.8% of LP, 5.7% of nailing (p>0.05), infections [11% of LP, 5.8% of nailing (p>0.05)], surgical revisions [2% of LP, 10% of nailing (p>0.05)]. DISCUSSION AND CONCLUSION The hypothesis was refuted. These results show that nailing conferred a faster recovery of weight-bearing, a better Parker score, and is associated with a lower mortality rate. The morbidity rate is comparable between the two techniques. Indeed, when the indication for osteosynthesis by LP or by nailing is made, and both choices are technically justifiable, it would be prudent to favor the technique, which carries the least risk, which in this case is nailing. This conclusion must, however, be taken in to consideration with regard to the reduced number of nailing. A larger series of nailing, particularly retrograde, would be necessary to be able to confirm this last difference between the 2 groups. LEVEL OF EVIDENCE IV; comparative retrospective study.

Abstract
INTRODUCTION In literature, there have been many studies conducted to research the alternatives of standard interlocking intramedullary nailing. The expandable wedge locked nail fixation, which is thought as a new alternative to the standard interlocking nailing, has been presented in previous numerical studies. The antegrade usage of the wedge locked nail fixation has provided promising results. From this point, the aim of the study is to evaluate mechanical behavior of its retrograde usage on femur models. Additionally, another aim of the study is to investigate the effect of fracture level on mechanical properties of the fixation. MATERIALS AND METHODS The mechanical behaviors of the wedge locked nail and standard interlocking nail fixations were compared by finite element methods. Sawbones femurs having osteotomies at five different levels to simulate different fractures were fixed with wedge locked nail or interlocking nail by using retrograde approach. With respect to the fracture level, two different nail lengths were used. Axial compression load was applied to fixations. The mechanical behaviors of the fixations were evaluated with respect to stiffness of the fixations and stresses occurred on both implants and bones. RESULTS Any of the wedge locked nail fixation did not slip at canal. The stress and stiffness results were mostly close with each other for both nail types. The maximum stresses at locking elements or bones contacting these elements increased with decreased distance between the fracture and relevant locking elements. DISCUSSION The wedge locked nail fixation showed comparable results to the standard interlocking nail fixation with respect to the stiffness and stress. Under axial loading, wedge locked nail provided a secured fixation without any slippage and preserved its position inside the medullary canal. It may be thought as a safe alternative to the standard interlocking nail fixation for retrograde usage. Additionally, according to stress results, it is advised to the surgeons to avoid a close locking to the fracture line.

Abstract
BACKGROUND The exact positioning of the cephalomedullary (CM) nail entry point for managing femoral fractures remains debatable, with significant implications for fracture reduction and postoperative complications. This study aimed to explore the variability in the selection of the entry point among trauma surgeons, hypothesizing potential differences and their association with surgeon experience. METHODS In this prospective multicenter study, 16 participants, ranging from residents to senior specialists, partook in a simulation wherein they determined the optimal entry point for the implantation of a proximal femoral nail antirotation (PFN-A; DePuy Synthes) in various femora. The inter- and intra-observer variability was calculated, along with comprehensive descriptive statistical analysis, to assess the variability in entry point selection and the impact of surgeon experience. RESULTS In this study, the mean distance from the selected entry points to the calculated mean entry point was 3.98 mm, with a smaller distance observed among surgeons with more than 500 implantations (ANOVA, p = 0.050). Intra-surgeon variability for identical femora averaged at 5.14 mm, showing no significant differences across various levels of surgical experience or training. Notably, 13.6% of selected entry points would not allow a proper intramedullary positioning of the implant, thereby rendering anatomical repositioning unfeasible. Among these impossible entry points, a significant skew towards anterior placement was observed (70.6% of the impossible entry points), with a smaller fraction being overly lateral (27.5%) or medial (13.7%). On a patient level, the impossibility rate varied widely from 0 to 35% among the different femora examined, with a significantly higher rate seen in younger patients (mean age 55.02 versus 60.32; t-test for independent samples, p = 0.04). CONCLUSIONS Significant variations exist in surgeons' selection of entry points for proximal femoral nailing, underscoring the task's complexity. Experience does not prevent the choice of unfeasible entry points, emphasizing the inadequacy of a universal approach and pointing towards the necessity for a patient-specific strategy for improved outcomes.

Abstract
Objective To investigate the position of the anterior fracture line in AO/Orthopaedic Trauma Association (AO/OTA) type A2 unstable intertrochanteric fractures and its impact on the incidence of anterior cortical reduction loss after cephalomedullary nail fixation. Methods A clinical data of 95 patients with intertrochanteric fractures who met the selection criteria between April 2020 and February 2023 was retrospectively analyzed. All patients were treated with cephalomedullary nail fixation, and the intra- and post-operative imaging data were complete. Among them, there were 37 males and 58 females. The age ranged from 61 to 97 years, with an average of 79.6 years. The time from injury to operation ranged from 7 hours to 11 days, with an average of 2.8 days. According to the 2018-AO/OTA classification standard, there were 39 cases of type 31-A2.2 and 56 cases of type 31-A2.3. Intraoperative fluoroscopy was used to record the number of patients with satisfactory fracture alignment. The preoperative CT data were imported into Mimics17.0 software to simulate the fracture reduction and measure the distance between the anterior fracture line and the intertrochanteric line bony ridge. The fractures were classified as transcapsular fractures, extra-capsular fractures, and intra-capsular fractures according to the distance. CT three-dimensional reconstruction was performed within 2 weeks after operation to observe the number of patients with anterior cortical reduction loss. The postoperative anterior cortical reduction loss incidence in patients with satisfactory fracture alignment, and the relationship between postoperative anterior cortical reduction loss and the position of the anterior fracture line were observed. Results There were 52 cases (54.7%) of transcapsular fractures, 24 cases (25.3%) of extra-capsular fractures, and 19 cases (20.0%) of intra-capsular fractures. Among them, 41 of the 52 transcapsular fractures had satisfactory fracture alignment, and 4 (9.8%) of them experienced anterior cortical reduction loss after operation; 19 of the 24 extra-capsular fractures had satisfactory fracture alignment, and no anterior cortical reduction loss occurred; 16 of the 19 intra-capsular fractures had satisfactory fracture alignment, and 7 (43.8%) of them experienced anterior cortical reduction loss after operation. There was a significant difference in the incidence of anterior cortical reduction loss between groups ( χ 2=8.538, P=0.003). All patients were followed up 3-26 months (mean, 9 months). Among them, 91 cases had fracture healing, and 4 cases had nonunion. Conclusion In AO/OTA type A2 unstable intertrochanteric fractures, where the anterior fracture line is located within the joint capsule, there is a high risk of anterior cortical reduction loss after operation.

Abstract
Objective To explore the effectiveness of irreducible intertrochanteric femoral fracture in the elderly by treating with folding top technique and right-angle pliers prying and pulling under G-arm X-ray fluoroscopy. Methods The clinical data of 74 elderly patients with irreducible intertrochanteric femoral fracture admitted between February 2016 and December 2022 and met the selection criteria were retrospectively analyzed. Among them, 38 cases were treated with folding top technique combined with right-angle pliers prying and pulling under G-arm X-ray fluoroscopy and intramedullary nailing fixation (study group), and 36 cases were treated with limited open reduction combined with other reduction methods and intramedullary nailing fixation (control group). There was no significant difference in baseline data between the two groups, such as age, gender, cause of injury, affected side and classification of fractures, complicated medical diseases, and time from injury to operation ( P>0.05). The operation time, intraoperative blood loss, hospital stay, fracture reduction time, fracture healing time, and complications of the two groups were recorded and compared. The quality of fracture reduction was evaluated by Baumgaertner et al. and Chang et al. fracture reduction standards. Results Patients in both groups were followed up 10-14 months, with an average of 12 months. The operation time and intraoperative blood loss in the study group were significantly less than those in the control group ( P<0.05), there was no significant difference in hospital stay between the two groups ( P>0.05). At 2 days after operation, according to the fracture reduction standards of Baumgaertner et al. and CHANG Shimin et al., the quality of fracture reduction in the study group was better than that in the control group, and the fracture reduction time in the study group was shorter than that in the control group, with significant differences ( P<0.05). After operation, the fractures of the two groups all healed, and there was no significant difference in healing time between the two groups ( P>0.05). During the follow-up, there was no complication such as incision infection, internal fixation failure, deep venous thrombosis of lower limbs, intramedullary nail breakage, spiral blade cutting, or hip varus in the two groups, except for 2 cases of coxa vara in the control group. Conclusion For the irreducible intertrochanteric femoral fracture, using folding top technique combined with right-angle pliers prying and pulling under G-arm X-ray fluoroscopy can obviously shorten the operation time, reduce the intraoperative blood loss, and improve the quality of fracture reduction.

Abstract
BACKGROUND The proximal femoral nail anti-rotation (PFNA) with cement enhancement enhances the anchorage ability of internal fixation in elderly with osteoporotic intertrochanteric fracture. However, whether it is superior to hemiarthroplasty is still controversial. The present study aimed to determine which treatment has better clinical outcomes among older patients. METHODS We retrospectively analyzed 102 elderly patients with osteoporosis who developed intertrochanteric fractures and underwent PFNA combined with cement-enhanced internal fixation (n = 52, CE group), and hemiarthroplasty (n = 50, HA group) from September 2012 to October 2018. All the intertrochanteric fractures were classified according to the AO/OTA classification. Additionally, the operative time, intraoperative blood loss, intraoperative and postoperative blood transfusion rates, postoperative weight-bearing time, hospitalization time, Barthel Index of Activities Daily Living, Harris score of hip function, visual analog (VAS) pain score, and postoperative complications were compared between the two groups. RESULTS The CE group had significantly shorter operative time, lesser intraoperative blood loss, lower blood transfusion rate, and longer postoperative weight-bearing time than the HA group. The CE group had lower Barthel's Index of Activities of Daily Living, lower Harris' score, and higher VAS scores in the first and third months after surgery than the HA group, but no difference was observed between the two groups from 6 months to 12 months. There was no significant difference in the total post-operative complications between the two groups. CONCLUSION The use of PFNA combined with a cement-enhanced internal fixation technique led to shorter operative time and lesser intraoperative blood loss and trauma in elderly patients as compared to HA.

Abstract
Maintaining post-operative mechanical stability is crucial for successfully healing intertrochanteric fractures treated with the Proximal Femoral Nail Antirotation (PFNA) system. This stability is primarily dependent on the bone mineral density (BMD) and strain on the fracture. Current PFNA failure analyses often overlook the uncertainties related to BMD and body weight (BW). Therefore, this study aimed to develop a probabilistic model using finite element modeling and engineering reliability analysis to assess the post-operative performance of PFNA under various physiological loading conditions. The model predictions were validated through a series of experimental test. The results revealed a negative nonlinear relationship between the BMD and compressive strain. Conversely, the BW was positively and linearly correlated with the compressive strain. Importantly, the compressive strain was more sensitive to BW than to BMD when the BMD exceeded 0.6 g/cm3. Potential trabecular bone compression failure is also indicated if BMD is equal to or below 0.15 g/cm3 and BW increases to approximately 2.5 times the normal or higher. This study emphasizes that variations in the BMD significantly affect the probability of failure of a PFNA system. Thus, careful planning of post-operative physical therapy is essential. For patients aged > 50 years restrictions on high-intensity activities are advised, while limiting strenuous movements is recommended for those aged > 65 years.

Abstract
BACKGROUND Blocking screw technique has been widely applied in the treatment of long shaft fractures. However, the evidence with regard to whether intramedullary nail combined with blocking screw technique has better clinical efficacy over other is not clear. The aim of the study was to explore the clinical efficacy and complications of intramedullary nail combined with blocking screw technique in the treatment of femoral or tibial shaft fractures. METHODS The PuMed, Embase, OVID, Cochrane library, Web of Science, Wanfang, CNKI and Weipu data were searched for studies of intramedullary nail combined with blocking screw in treatment of femoral or tibial shaft fracture published up to Aug 31 2023. Methodological quality of the trials was assessed, relevant data were extracted, and RevMan 5.3 and Stata 15.0 software were used to perform the meta-analysis of parameters related to the consequences. RESULT Twenty articles were included, including 1267 patients. Meta-analysis results showed that compared with the non-blocking screw group, the blocking screw group had longer operation time (WMD = 13.24; 95% CI = 5.68-20.79, P = .0006) and more intraoperative fluoroscopy times (WMD = 57.62; 95% CI = 25.82-89.42, P = .0002). However, the postoperative therapeutic response rate was higher (OR = 5.60; 95% CI = 2.10-14.93, P = .0006), postoperative ankle joint function was better (OR = 3.48; 95% CI = 1.20-10.13, P = .02), and fracture healing rate was higher (OR = 3.56; 95% CI = 1.43-8.89, P = .006), fracture healing time was shorter (WMD = -3.59; 95% CI = -4.96 to -2.22, P < .00001), intraoperative blood loss was less (WMD = -54.80; 95% CI = -88.77 to -20.83, P = .002), hospitalization time was shorter (WMD = -1.66; 95% CI = -2.08 to -1.24, P < .00001), and complications were less (OR = 0.38; 95% CI = 0.16-0.89, P = .01). There was no statistical significance in the range of motion of knee joint between the 2 groups (WMD = 10.04; 95% CI = -1.51 to 21.59, P = .09). CONCLUSIONS Current evidence shows that intramedullary nail combined with blocking screw technique in the treatment of lower limb long bone fracture has the advantages of good clinical efficacy, high fracture healing rate, short fracture healing time, good joint function, less complications and so on, which is worthy of clinical recommendation.

Abstract
INTRODUCTION Radial neck fractures in adults are rare, but outcomes are often poor. Closed reduction and internal fixation (CRIF) technique has been advocated for the treatment of minimally displaced fractures in children, with a few reports on adult subjects. The aim of the present paper is to investigate mid-term results of a CRIF technique in adults with retrograde intramedullary K-wires in Mason's type II and III fractures. The proposed technique yields to good anatomical reduction of displaced neck fractures, faster rehabilitation, and easier hardware removal after fracture consolidation. MATERIAL AND METHODS A consecutive series of 17 patients were treated with closed reduction and intramedullary osteosynthesis, and outcomes were retrospectively evaluated. Elbow X-ray (XR) and CT scan were obtained preoperatively. Objective assessment before surgery and at an average 36-month follow-up included active and passive elbow range of motion (ROM). Functional evaluation was carried out through the collection of the Mayo Elbow Performance Score (MEPS), the Disabilities of the Arm, Shoulder, and Hand (DASH) score, and Elbow Self-Assessment Score (ESAS). XR at last follow-up was evaluated. RESULTS The cohort included 10 males and seven females, with a mean age of 32 years. Patients returned for a follow-up evaluation at a mean of 36 months (range 6-43 m) form the surgery. The DASH score revealed good to excellent outcomes with a mean of 6.32 ± 10.24 points at last follow-up. The ESAS was 98.35 ± 1.89, indicating a non-restricted elbow function. Acceptable radiographic healing was achieved in all patients. CONCLUSIONS The advocated technique is promising for obtaining good reduction and stabilization, and good to excellent satisfaction for patients. Given the challenging technique, the learning curve could be long and initial results unsatisfactory. More research with larger cohorts and improved study design could be carried out, comparing the technique with the current choice of treatment (ORIF, radial head resection).

Abstract
BACKGROUND Femur intertrochanteric fractures are performed commonly in a supine position with a traction table. There is a challenge in obtaining traction tables, especially in low- and middle-income countries. However, there is still a debate on which position should be preferred if the traction table cannot be obtained. METHODS A total of 123 patients who were treated for femur intertrochanteric fracture (AO/OTA A1 or A2) using cephalomedullary nail (CN) were retrospectively analyzed. All three positions without traction table (supine:25 patients, semilithotomy:36 patients and lateral decubitus:62 patients) were compared according to preparation time, surgical time, Tip-Apex distance (TAD), zones of lag screw placement, collodiaphyseal angle (CDA), CDA difference (∆ CDA), postoperative posterior sag, medial cortical support and Baumgardner reduction quality criteria. RESULTS The preparation time was longer in the semilithotomy group, and surgery time was longer in the supine position group. There was no difference according to total time, surgical time, TAD, CDA difference (∆ CDA), postoperative posterior sag, medial cortical support and Baumgardner reduction quality criteria. Target lag screw placement is superior in supine and semilithotomy group than lateral decubitus. CONCLUSION This study concluded that there was a difference in preparation time, surgery time and optimal lag screw placement in the lateral plane between groups. The surgeon may prefer all three methods according to patient benefit and surgeon familiarity.

Abstract
Background Reverse oblique intertrochanteric fractures (ROFs) are unstable extracapsular hip fractures that present a mechanical challenge. These fractures are classified as AO/Orthopaedic Trauma Association (OTA) 31-A3 according to the Trauma Association classification system and can further be subclassified into 3 subtypes based on their specific characteristics. The study aimed to evaluate and compare the radiographic and clinical outcomes of the 3 subtypes of ROFs. Methods A retrospective study was conducted at a single high-volume, tertiary center, where data were collected from electronic medical records of consecutive patients who underwent surgical fixation of AO/OTA 31-A3 fractures. Patients with less than 1-year follow-up, pathological fractures, and revision surgery were excluded. The subtypes of fractures were classified as 31-A3.1 (simple oblique), 31-A3.2 (simple transverse), and 31-A3.3 (wedge or multi-fragmentary). The operation was done using 4 different fixation methods, and radiological evaluation was performed at routine intervals. Results The final population consisted of 265 patients (60.8% women) with a mean age of 77.4 years (range, 50-100 years) and the mean follow-up time was 35 months (range, 12-116 months). The incidence of medical complications was similar across the groups. However, there was a trend toward a higher incidence of orthopedic complications and revision rates in the 31-A3.2 group, although this was not statistically significant (p = 0.21 and p = 0.14, respectively). Conclusions Based on the findings of this study, no significant differences were observed between the groups, indicating that the subclassifications of AO/OTA 31-A3 fractures do not have a significant impact on surgical outcomes or the occurrence of postoperative complications.

Abstract
INTRODUCTION The purpose of this study was to evaluate outcomes following reverse obliquity (RO) intertrochanteric hip fractures based on the use of short cephalomedullary nails (CMNs) compared to long CMNs for fixation. METHODS An IRB-approved prospectively collected hip fracture registry at an urban academic medical center was queried for all AO/OTA 31A3.1-3 reverse obliquity intertrochanteric (RO) fractures. One hundred and seventy patients with age > 55 years old and minimum 6-month follow-up were identified for analysis. Data was collected for patient demographics, injury details, intraoperative radiographic parameters, perioperative physiologic parameters, hospital quality measures, and outcomes including radiographic time to healing, need for reoperation, nonunion, and mortality. Comparative analyses were conducted between cohorts. Additional multivariable binary logistic and linear regression analyses were performed to evaluate for factors independently associated with short and long nail usage. RESULTS The mean age of the entire cohort was 80.91±10.09 years: 103 patients had a long CMN implanted, and 67 patients had a short CMN implanted. There were no demographic differences or differences in radiographic time to healing, rates of mortality, readmission, nonunion, and need for reoperation. Univariable analysis revealed that short CMN had lower intraoperative blood loss (111.19±83.97 mL vs 176.72±161.45 mL, p = 0.002), decreased need for transfusion (37% vs. 55 %, p = 0.022), and shorter procedures (118.67±57.87 min vs. 148.95±77.83 min, p = 0.002. Multivariable analysis revealed that short nail usage was associated with decreased intraoperative blood loss, decreased need for transfusion, and shorter operative times. CONCLUSION Nail length does not affect healing or hospital quality outcomes in the treatment of RO hip fractures. The use of short CMNs for these fractures did correlate with lower intraoperative blood loss, operative time, and need for blood transfusion, with non-inferior outcomes and similar hospital quality measures when compared to long CMNs.

Abstract
PURPOSE The purpose of this meta-analysis is to analyse the literature on plate-assisted reduction during intramedullary nailing of tibial shaft fractures and to compare the rates of infection and nonunion. METHODS The databases Medline, Embase, and Web of Science were searched from inception to February 2022 for literature comparing plate-assisted reduction during intramedullary nailing of extra-articular tibia fractures to standard, closed means of reduction. Data were extracted and pooled in a random effects meta-analysis for the primary outcomes of nonunion and infection risk. RESULTS Five comparative studies were identified including 520 total patients, of which 151 underwent tibial nailing with the use of plate-assisted reduction with an average follow-up time of 17.9 months. Approximately two-thirds of patients retained the plate used to assist reduction during intramedullary nailing (102 of 151). Pooled analysis of the infection rates found no significant difference with plate-assisted intramedullary nailing (Risk Ratio [RR] 0.90, 95% CI 0.49-1.65, p = 0.72), and for nonunion rates, there was also no significant difference with plate-assisted intramedullary nailing (Risk Ratio [RR] 0.80, 95% CI 0.40-1.60, p = 0.53). CONCLUSIONS Plate-assisted reduction during intramedullary nailing of tibia shaft fractures was not associated with an increased risk for nonunion or infection, and can be safely applied as an adjunct for reduction in challenging fracture patterns, without the need for later removal. However, evidence is quite limited and further investigation into the use of provisional plating as a technique is needed as its use in intramedullary nailing continues to expand.

Abstract
BACKGROUND Tibiotalocalcaneal arthrodesis (TTCA) is a salvage procedure to fuse the ankle and subtalar joints to treat severe ankle and hindfoot disease. Patients often have multiple operations before a TTCA. A below knee amputation (BKA) has major physical and psychological impacts. Our aim is to investigate the outcomes of these treatments in salvage situations, with a focus on objective functional measurements and patient reported outcome measures (PROMs). METHODS 52 patients underwent TTCA with a retrograde intramedullary nail and contacted for clinical and functional assessments and compared to patients who underwent traumatic BKA. PROMS such as AOFAS score, SF-36 and foot function index (FFI), and objective functional outcome measures were used. RESULTS Of the 52 TTCA patients, 28 patients were recruited for follow-up. 35.7% of patients had postoperative complications. Mean postoperative AOFAS score was 63.9 ± 8.4 (range, 47-81), FFI 48.8 ± 15.8 (range, 22.2-75.2). 11 BKA patients (mean age 46.4 years) were included as control group. BKA patients scored higher than the TTCA patients on SF-36 physical functioning (p < 0.01) and SF-36 mental health (p < 0.05) subscales. The flat-surface functional tests (timed up and go test, 2-minute walk test, 10-meter walk test) showed significantly (p < 0.05) better outcomes for the BKA compared to TTCA. CONCLUSIONS A TTCA is a salvage procedure with high complication rates. Functional and psychometric results are reduced compared to the normal population. Patients after a BKA had significantly better scores on SF-36 functional and mental health subscales and better functional outcomes for flat ground activities compared to TTCA. Heterogeneity of the TTCA and BKA patient cohorts is a limitation of this study. With these results in mind, the outlook of a BKA is not necessarily a grim one. They may be used by surgeons to counsel patients preoperatively when managing complex ankle and hindfoot disease. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
PURPOSE Compare two simple ways for treating boxer's fractures in active adults; conservative management by ulnar gutter slab and transverse pinning in fixation of fifth metacarpal's neck fracture regarding union, functional outcomes, and complications. PATIENTS AND METHODS Ninety patients with fifth metacarpals' neck fractures with palmar angulation (30-70°) were managed either conservatively by an ulnar gutter slab or surgically by transverse pinning technique from January 2020 to December 2021. Only 84 patients completed a 1-year follow-up. Patients with old, open, or mal-rotated fractures were excluded. The block-randomization method was used to create equal groups. Patients were evaluated clinically and radiologically every 2-3 weeks until union, then at 6 and 12 months. Functional assessment at the final visit was done using the quick DASH score, total active motion (TAM), and total Active Flexion (TAF). RESULTS The mean radiological union time for the conservative group in this study was 7.76 weeks, while for the transverse pinning group, it was 7.38 weeks. There was no statistically significant difference between the two techniques regarding union rates and functional outcomes. All patients returned to their pre-injury jobs and level of activity. CONCLUSION Both conservative management in ulnar gutter slab and percutaneous transverse pinning are considered effective methods in the treatment of simple extra-articular fifth metacarpal neck fractures with angulation between 30 and 70 degrees (AO: 77 A3.1). The functional and radiological results using both methods were satisfactory and statistically comparable.

Abstract
INTRODUCTION German-speaking surgeons have left a deep imprint on the history of diagnostics and treatment of proximal femur fractures. Some of the studies published in German have fell into oblivion, others are cited until today, although sometimes quite inaccurately. The cause of such inaccuracies are citations from secondary sources due to unavailability of the original or inability to read it because of a language barrier. In the current literature, globally predominated by English articles, the "German history" of treatment of proximal femur fractures remains undervalued. The aim of the present article is to point out its contribution. MATERIALS AND METHODS Literature search was performed in original publications and historical sources. RESULTS The German-speaking surgeons have considerably contributed to the development of the treatment of proximal femur fractures. The analyzed period between 1847 and 1970 may be divided into three basic periods. In the first period (1847-1896), the German-speaking surgeons (Langenbeck, Trendelenburg, König, Heine, Dolinger) were the first worldwide to start treating the fractures of proximal femur operatively. In the second period (1897-1935), mainly in the 1930s, the initiative in Europe was taken over by surgeons publishing studies in France and in Belgium. Overseas, American surgeons were coming to the forefront. In Germany, only Pauwels developed the first biomechanical classification of femoral neck fractures. In the third period (1936-1970), mainly in the 1940s and 1950s, implants were designed (Pohl, Künstcher), based on close collaboration between German engineers and surgeons, that served as a model for a dynamic hip screw and a proximal femoral nail, which are currently the implants of choice in the treatment of trochanteric fractures. CONCLUSION The historical contribution of German-speaking surgeons to understanding the issue of proximal femur fractures and their operative treatment is far more significant than presented in the historical studies published in English.

Abstract
PURPOSE Freehand distal interlocking of intramedullary nails remains a challenging task. Recently, a new training device for digitally enhanced hands-on surgical training (DEHST) was introduced, potentially improving surgical skills needed for distal interlocking. AIM To evaluate whether training with DEHST enhances the performance of novices (first-year residents without surgical experience in freehand distal nail interlocking). METHODS Twenty novices were randomly assigned to two groups and performed distal interlocking of a tibia nail in mock operation under operation-room-like conditions. Participants in Group 1 were trained with DEHST (five distal interlocking attempts, 1 h of training), while those in Group 2 did not receive training. Time, number of X-rays shots, hole roundness in the X-rays projection and hit rates were compared between the groups. RESULTS Time to complete the task [414.7 s (range 290-615)] and X-rays exposure [17.8 µGcm2 (range 9.8-26.4)] were significantly lower in Group 1 compared to Group 2 [623.4 s (range 339-1215), p = 0.041 and 32.6 µGcm2 (range 16.1-55.3), p = 0.003]. Hole projections were significantly rounder in Group 1 [95.0% (range 91.1-98.0) vs. 80.8% (range 70.1-88.9), p < 0.001]. In Group 1, 90% of the participants achieved successful completion of the task in contrast to a 60% success rate in Group 2. This difference was not statistically significant (p = 0.121). CONCLUSIONS In a mock-operational setting, training with DEHST significantly enhanced the performance of novices without surgical experience in distal interlocking of intramedullary nails and hence carries potential to improve safety and efficacy of this important and demanding surgical task to steepen the learning curve without endangering patients.

Abstract
INTRODUCTION The use of magnetic resonance imaging (MRI) with a magnetic intramedullary lengthening nail in place is contraindicated per the manufacturer due to the concern of implant activation and migration. A prior in vitro study did not confirm these complications only noting that a 3.0 T MRI weakened the internal magnet. Therefore, a retrospective analysis of patients who underwent an MRI with a magnetic nail in place was performed to determine if any adverse effects occurred in the clinical setting. MATERIALS AND METHODS A retrospective review of all patients who underwent an MRI with a magnetic lengthening nail in place was performed. The time spent being imaged in the MRI, number of times the patient entered the MRI suite, and the images obtained were recorded. Radiographs were performed before and after the MRI to determine if any hardware complications occurred. The patients were monitored for any adverse symptoms while they were in the suite. RESULTS A total of 12 patients with 13 nails were identified. Two patients underwent imaging with a 3.0 T MRI while the remaining 10 underwent imaging with a 1.5 T MRI. Each patient entered the MRI suite 2.1 times and spent an average of 84.7 min being imaged in the MRI (range 21-494). No patients noted any adverse symptoms related to the nail while in the suite and no hardware complications were identified. CONCLUSION MRI appears to be safe with a magnetic nail in place and did not result in any complications. Given the manufacturer's recommendations, informed consent should be obtained prior to an MRI being performed and a 3.0 T MRI should be avoided when possible if further activation of the nail is required.

Abstract
OBJECTIVES Tibiotalocalcaneal (TTC) nailing in the setting of acute ankle trauma has become increasingly popular. No consensus exists as to whether formal joint preparation is necessary, although there is some concern that residual motion at unprepared joints may lead to implant loosening and/or breakage. The objective of this study was to quantify the proportion of tibiotalar and subtalar articular surface destruction that occurs during reaming for TTC nail fixation. METHODS Twelve cadaver lower extremities were procured. The specimens were pinned into neutral ankle and hindfoot alignment. A guidewire was inserted under fluoroscopy, followed by a 12-mm opening reamer. The specimens were then dissected, exposing the tibial plafond, talar dome, posterior facet of the talus, and posterior facet of the calcaneus. Images of each joint were obtained, and ImageJ software was used to calculate the total joint surface area and the area of articular destruction. RESULTS The mean proportion of articular cartilage destruction was 9.3%, 10.3%, 8.9%, and 10.3% for the tibial plafond, talar dome, posterior facets of the talus, and posterior facets of the calcaneus, respectively. No joint destruction was observed in the middle facets of the subtalar joint. CONCLUSIONS Reaming for TTC nail placement violates approximately 10% of each articular surface of the tibiotalar and subtalar joints. Retention of 90% of the articular surface may allow for residual motion at the joints and therefore potentially substantial stress on the implant. Formal joint preparation for the purposes of achieving fusion during TTC nail placement may be beneficial to prevent implant loosening or breakage.

Abstract
External fixation is an essential surgical technique for treating trauma, limb lengthening and deformity correction, however infection is common, with infection rates ranging from 4.5 to 100% of cases. Throughout the literature researchers and clinicians have highlighted a relationship between excessive movement of the pin and skin and an increase in the patient's risk of infection, however, currently no studies have addressed this role of pin-movement on pin-site wounds. This preliminary study describes a novel in vitro pin-site model, developed using a full-thickness human skin equivalent (HSE) model in conjunction with a bespoke mechanical system which simulates pin-movement. The effect of pin-movement on the wound healing response of the skin equivalents was assessed by measuring the expression of pro-inflammatory cytokines. Six human skin equivalent models were divided into three test groups: no pin as the control, static pin-site wound and dynamic pin-site wound (n = 3). On day 3 concentrations of IL-1α and IL-8 showed a significant increase compared to the control when a static fixation pin was implanted into the skin equivalent (p < 0.05) and (p < 0.005) respectively. Levels of IL-1α and IL-8 increased further in the dynamic sample compared to the static sample (p < 0.05) and (p < 0.0005). This study demonstrates for the first time the application of HSE model to study external-fixation pin-movement in vitro. The results of this study demonstrated pin-movement has a negative effect on soft-tissue wound-healing, supporting the anecdotal evidence reported in the literature, however further analysis of wound heading would be required to verify this hypothesis.

Abstract
BACKGROUND Stability is regarded as an important factor for proper healing and avoiding secondary dislocation in osteoporotic fractures of the proximal humerus. Several surgical techniques have been proposed for treatment, including intramedullary nail osteosynthesis and locking plate fixation. This study introduces a novel approach that combines both techniques and compares its primary stability with conventional methods. METHODS The study involved 25 osteoporotic humeri with two-part fracture models, which were randomly assigned to locking-plate fixation, intramedullary nailing, or a combination of both techniques. The specimens were subjected to sinusoidal loading at 250 N in 20° abduction for 5000 cycles and then to quasi-static loading until failure. Fracture movement, failure mode, and failure load were measured and compared among the groups. FINDINGS The groups fixated with intramedullary nailing and the groups fixated with intramedullary nailing and locking plate fixation showed significantly lower fracture motion than the group using locking plate fixation only (p < 0.005) and significantly higher load to failure (p = 0.007 and p = 0.0062, respectively). There was no significant difference between the group using intramedullary nailing and the group using locking-plate fixation and intramedullary nailing in fracture movement or load-to-failure (p > 0.005). INTERPRETATION The results indicate that locking plate fixation provides less primary stability than intramedullary nailing or the combined of both techniques. This combined approach may offer advantages as a treatment for complex proximal humeral fractures in osteoporotic bone, and specific implants should be developed to ensure optimal treatment.

Abstract
OBJECTIVES To evaluate initial fracture morphology influences on outcomes in simple 2-part pertrochanteric fracture, with a focus on the basicervical component and its initial impaction. METHODS DESIGN A retrospective cohort series. SETTING Single Level I Trauma Center. PATIENTS SELECTION CRITERIA Patients older than 60 years with intertrochanteric fractures between 2011 and 2022 were retrospectively reviewed. Inclusion criteria comprised simple 2-part pertrochanteric fractures (Orthopaedic Trauma Association [OTA]/Arbetisgemeinschaftfur Osteosynthesefragen [AO] 31-A1.2) with a basicervical component who underwent cephalomedullary nailing and had a minimum follow-up of 6 months. Patients were divided whether the basicervical component was impacted into the medullary canal (intramedullary impaction [II] group) or displaced beyond the medullary canal (extramedullary [E] group). Exclusion criteria encompassed pathologic fractures, nondisplaced fractures, and basicervical neck fractures (OTA/AO 31-B3). OUTCOME MEASUREMENTS AND COMPARISONS Reduction status was assessed as unacceptable if the head and neck (proximal) fragment was positioned intramedullary with respect to the distal fragment in either the anterior posterior or cross-lateral x-ray and acceptable otherwise. In addition, the degree of impaction on x-ray and CT scans (coronal, sagittal, axial) at injury was analyzed as a risk factor for failure. Revision rates and lag screw sliding over 15 mm were compared between the II and E groups. RESULTS Hundred fifteen patients (95 female, average age 80 years) were included. The II group (n = 58) compared with E group (n = 57) showed more acceptable postoperative reductions (57% vs. 81%, P = 0.001), but significantly higher fixation failure (16% vs. 3.5%, P = 0.048) and fracture collapse (28% vs. 7%, P = 0.01). II was identified as a significant independent predictor for failure (odds ratio 5.64, 95% confidence interval, 2.14-16.9, P < 0.001) with more than 19.5-mm impaction in sagittal CT scan as the threshold linked to increased failure risk. CONCLUSIONS This study highlights the significance of specific intertrochanteric fracture patterns, particularly II of a basicervical component and impaction severity (≥19.5 mm), as drivers of fixation failure. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
PURPOSE To underline the feasibility of achieving early weight bearing in patients with distal end-segment femur fractures (AO/OTA 33) treated with retrograde intramedullary nailing and supplemental plate or lag screws in the absence of C-arm. METHODS 41 distal end-segment femur fractures (DFFs) included in the study were treated with SIGN nails with or without a side plate in a center that lacked intraoperative fluoroscopy and fracture table. A medial or lateral para-patellar incision was used for fracture reduction, nail insertion and side plate placement. Follow-ups were done at six weeks, 12 weeks, and six months post-operatively. RESULTS Distal end-segment fractures constituted 13.2% of all femur fractures treated. The patients' mean age and range were 49.6 and 23-83 years respectively. They were mostly injured in road traffic accidents. 27 were daily-income earners. By the 12th week post-operatively, 82.1% of them could flex their knee beyond 90°, all of them could bear weight fully, and 71.8% could squat & smile. CONCLUSION The study highlighted the procedure for retrograde nailing of DFFs in a setting without the requisite facilities for minimally-invasive surgeries. The findings demonstrated the feasibility of achieving an expedited weight bearing for the predominantly daily-income-earning victims to ensure early return to work and poverty reduction. While the small sample size is a limitation, the study does provide information that could serve as a basis for future randomized controlled trials in low-resource settings.

Abstract
Objective To introduce a locating device for the entry point of intramedullary nail based on the inertial navigation technology, which utilizes multi-dimensional angle information to assist in rapid and accurate positioning of the ideal direction of femoral anterograde intramedullary nails' entry point, and to verify its clinical value through clinical tests. Methods After matching the locating module with the developing board, which are the two components of the locating device, they were placed on the skin surface of the proximal femur of the affected side. Anteroposterior fluoroscopy was performed. The developing angle corresponding to the ideal direction of entry point was selected based on the X-ray image, and then the yaw angle of the locating module was reset to zero. After resetting, the locating module was combined with the surgical instrument to guide the insertion angle of the guide wire. The ideal direction of entry point was accurately located based on the angle guidance. By setting up an experimental group and a control group for clinical surgical operations, the number of guide wire insertion times, surgical time, fluoroscopy frequency, and intraoperative blood loss with or without the locating device was recorded. Results Compared to the control group, the experimental group showed significant improvement in the number of guide wire insertion times, surgical time, fluoroscopy frequency, and intraoperative blood loss, with a statistically significant difference (P<0.01). Conclusion The locating device can assist doctors in quickly locating the entry point of intramedullary nail, effectively reducing the fluoroscopy frequency and surgical time by improving the success rate of the guide wire insertion with one shot, improving surgical efficiency, and possessing certain clinical value.

Abstract
OBJECTIVE To explore clinical efficacy of proximal femoral nail anti-rotation(PFNA),InterTan and proximal femoral bionic intramedullary nail (PFBN) in treating femoral intertrochanteric fracture. METHODS Clinical data of 120 patients with intertrochanteric fracture who were underwent closed reduction intramedullary nail-internal fixation from January 2020 to January 2021 were retrospectively analyzed. According to methods of internal fixation,patients were divided into 3 groups. There were 25 patients in PFBN group,including 16 females and 9 males,aged from 69 to 79 years old with an average of (73.67±5.16) years old. There were 55 patients in PFNA group,including 38 females and 17 males,aged from 68 to 80 years old with an average of (74.23±5.57) years old. There were 40 patients in InterTan group,including 26 females and 14 males,aged from 68 to 79 years old with an average of (73.45±5.34) years old. Operative time,intraoperative blood loss,incision length,hospital stay,weight-bearing time,fracture healing time and complications among 3 groups were compared,and clinical effect was evaluated by Harris score of hip function before operation,1,6 and 12 months after opertaion,respectively. RESULTS Patients among 3 groups were successfully completed operation and were followed up for more than 12 months. There were no significant difference in hospital stay,operative time,intraoperative blood loss and incision length among 3 groups (P>0.05). Weight bearing time of PFBN group (7.98±1.34) d and InterTan group (8.22±0.46) d were earlier than that of PFNA group (10.27±0.66) d(P<0.01). Fracture healing time of PFBN group (10.14±2.33) weeks and InterTan group (11.87±2.48) weeks were earlier than that of PFNA group (13.68±2.36) weeks (P<0.01). One month after operation,Harris score in PFBN group (70.52±5.34) and InterTan group (69.81±6.17) was higher than that of PFNA group (51.46±5.36),and there was no significant difference between PFBN group and InterTan group (P>0.05). There were no significant difference in Harris scores among 3 groups before operation,6 and 12 months after opertaion(P>0.05). Cases of complication of InterTan group and PFNA group were lower than that of PFNA group (P<0.05). CONCLUSION PFBN and InterTan for the treatment of intertrochanteric fracture have advantages of faster fracture healing,earlier weight-bearing time and fewer postoperative complications than traditional PFNA,but three operations could achieve higher effective rates without significant difference in long-term results.

Abstract
Manufacturers aim to design implants fitting for the broadest possible population segment. Due to the scarcity of available morphological data of intact long bones, anatomical collections of historical bone specimens may represent valuable additional sources. Previous work on femoral morphology measurements suggests that historical specimens are widely consistent with data from present-day populations. This study aimed to investigate whether this also applies to the anatomical fitting of a clinically used femoral nail. Nail fit was computer-graphically quantified through virtual implantation into CT-based 3D models of 52 femora, comprising a subset representative of the present-day Caucasian population (n = 31), a subset from a historical medieval European bone collection (n = 20), and additionally, a dataset from a natural ice mummy from the Neolithic period. Nail fit was assessed by nail protrusion (area and distance) to the inner cortex surface and the distal nail tip's position in the medullary canal. Assessed measurements and parameters of the present-day Caucasian subset were mostly consistent with those of the medieval European subset. After adjusting for multiple testing, only the distance from lateral nail entry point to shaft axis remained significantly (p = 0.03) different when comparing our modern and medieval subsets. Subsequent bivariate (Spearman) correlation analyses for both subsets (modern and medieval) combined showed that of the three variables representing basic demographic parameters, individual age, biological sex, and femur length, most statistically significant associations to the examined nail fit measurements were found for age (six measurements at a level of p < 0.05), however, with a relatively weak monotonic correlation (rho values ranging between ±0.31 and ±0.37). The measurements for the Iceman's femur lie within the range of the modern and historical subgroups, but in some cases, differ by more than one standard deviation from the mean. Our results confirm previous findings, suggesting that more recent historical bone specimen collections may indeed be a convenient and easily accessible source of new 3D morphological data and complement existing data to be used for the development of femoral nails.

Abstract
BACKGROUND Surgical treatment of irreducible distal radius diaphyseal- metaphyseal junction fractures involves difficulties as the fracture remains too proximal for K-wire fixation and too distal for the elastic stable intramedullary nail. Our study aims to present the clinical results of applying an elastic stable intramedullary nail with a poller K-wire to achieve both reduction and stable fixation. PATIENTS AND METHODS A retrospective analysis was performed on 26 patients who underwent ESIN with a poller K-wire for distal radius diaphyseal-metaphyseal region fracture. Reduction parameters such as residual angulation and alignment were evaluated on postoperative follow-up radiographs. Changes in angular and alignment parameters on follow-up radiographs were recorded. Wrist and forearm functions were evaluated at the last follow-up. RESULT There were 17 male and nine female patients with an average age of 10.9. The residual angulation in coronal and sagittal planes on immediate postoperative radiographs was 4.0 ± 1.62° and 3.0 ± 1.26°, respectively. The mean translation rate on immediate postoperative radiographs was 6.0 ± 1.98% and 5.0 ± 2.02% in the coronal and sagittal planes, respectively. No change was observed in translation rates in the last follow-ups. The mean angulation in the coronal and sagittal planes measured on 6th-week radiographs was 4.0 ± 1.72°and 3.0 ± 1.16°, respectively. No significant difference was observed in angular changes in the sagittal and coronal planes at the last follow-up (p > 0.05). No tendon injury or neurovascular injury was observed in any of the patients. CONCLUSION In the surgical treatment of pediatric DRDMJ fractures, applying ESIN with poller K-wire is an effective, safe, and novel method for achieving reduction and stable fixation.

Abstract
Elastic stable intramedullary nailing (ESIN) has been shown to be an effective form of surgical management for lower-extremity diametaphyseal fractures in pediatric patients, but studies are limited because ESIN treatment for these fractures is relatively uncommon. We sought to determine whether ESIN can be used effectively in the most distal or proximal short-segment forms of these fractures. We queried the electronic medical record system at Johns Hopkins Hospital using Current Procedural Terminology codes for femur and tibia fractures treated with ESIN in patients under 18 years old between January 2015 and October 2022. Preoperative and postoperative radiographs were subsequently reviewed to identify patients with a proximal or distal third femoral or tibial shaft fracture treated with ESIN and to define criteria for short-segment diametaphyseal fractures. We used Beaty radiological criteria to evaluate radiographic outcomes and Flynn titanium elastic nails (TENs) outcome scale to assess clinical recovery after radiographic evidence of union. There were 43 children who met the inclusion criteria. Among them, 10 patients had short-segment diametaphyseal fractures. There were 22 (51.2%) who sustained femur fractures and 21 (48.8%) who sustained tibia fractures. Using Beaty radiologic criteria, ESIN was associated with more satisfactory outcomes in patients with distal or proximal third shaft fractures (32/33) than in patients with short-segment diametaphyseal fractures (7/10) (P = .03). Using the TENs outcome scale, 21 (63.4%) patients with distal or proximal third shaft fractures had excellent results, 11 (33.3%) had satisfactory results, and 1 (3%) had a poor result. Among patients with short-segment diametaphyseal fractures, 4 (40%) had excellent results, 5 (50%) had satisfactory results, and 1 (10%) had a poor result. There were no differences in TENs outcomes between the groups (P = .24). Patients with short-segment lower-extremity diametaphyseal fractures treated with ESIN had worse radiographic outcomes but did no worse clinically than patients with distal or proximal third shaft fractures. Consequently, ESIN should be considered a safe and effective surgical management option for pediatric patients with even the most distal or proximal forms of these fractures.

Abstract
INTRODUCTION Medullary hip screws (MHSs) are the most common treatment of intertrochanteric hip fractures because they can be used for varied fracture patterns and resist shortening. Identifying the appropriate MHS entry point can be intellectually and technically challenging. We aimed to quantify the variability in the ideal entry point (IEP) for MHSs. METHODS Standing alignment radiographs of 50 patients were evaluated using TraumaCad (Brainlab). The femoral neck shaft angle and the offset from the tip of the greater trochanter (GT) to the femur's longitudinal axis ('greater trochanter offset') were measured. Five MHS system templates were superimposed on the femur's longitudinal axis, and the distance from the GT tip to MHS's top center was measured. Five independent reviewers each templated 20 images such that all images were measured at least twice. A random sample of five images was selected for all five raters to measure and to calculate an intraclass coefficient Mean IEPs were compared with an independent sample Student t -test. RESULTS The mean GT offset was 13.5 ± 5.6 mm (range 12.9 to 26.7 mm). The mean neck shaft angle was 129.5 ± 4.0 (range 120 to 139). The mean IEP for nail systems ranged from 5.7 to 7.1 mm medial to the GT tip; there was no notable difference in pairwise comparison of nail systems or in aggregate. Intraclass coefficient for all ratings, measurements, and nail types ranged from moderate to good. Both intra-rater and inter-rater reliability were excellent. DISCUSSION AND CONCLUSION In a sample with broad variation in femoral anatomy, there is a specific, roughly 1.5 mm wide interval that is 6.4 mm medial to the GT tip that serves as the IEP for the most common MHS systems. No notable difference seems to exist in the IEP among these MHS systems.

Abstract
Objective To review the research progress of the weak state of the lateral wall in intertrochanteric fracture, in order to provide clinical references. Methods The relevant research literature on the lateral wall of intertrochanteric fracture at home and abroad in recent years was summarized and analyzed in terms of morphology, fracture line in coronal plane, and bone density. Results Assessment of weak state of the lateral wall is particularly important in the treatment of intertrochanteric fractures. Lateral wall thickness is the main way to assess the weak state of the lateral wall, but there are still problems. Many scholars at home and abroad have studied various aspects such as width, height, and length of the anterior cortex, but there is a lack of a comprehensive assessment method. Coronal fractures affect lateral wall morphology and are difficult to detect on X-ray films, requiring vigilance on the part of the clinician. Further research is needed to clarify the correlation between bone density and the weak state of the lateral wall. The femur lesser trochanter fractures interacts with the latertal wall, and the lesser trochanter fracture exacerbates the weak state. The soft tissue around the lateral wall also affects the weak state, so attention must be paid to protecting the soft tissues during operation. Conclusion There are more methods for assessing the weak state of the lateral wall, but none of them has formed a unified standard. Most of the current studies assess the weak state from a single perspective and lack a comprehensive assessment of all aspects affecting the lateral wall. Fewer studies have been conducted to assess the residual lateral wall function after a partial fracture of the lateral wall, and further research is needed.

Abstract
Objective To analyze the causes and treatment of off target of the distal interlocking screws when short cephalomeduallry nails were installed through jig-guided targeting device, and to put forward the technical points to prevent off target. Methods Retrospective analysis of 9 patients with intertrochanteric fractures treated between July 2014 and June 2023 was conducted, in which off target occurred during the insertion of the distal interlocking screw by jig-guided targeting device in short cephalomedullary nailling (<24 cm). There were 1 male and 8 females, with an average age of 82.7 years (range, 73-94 years). There were 3 cases of type A1, 5 cases of type A2, and 1 case of type A3 according to 2018-AO/Orthopaedic Trauma Association (AO/OTA) fracture classification. As for the misaligned distal interlocking screw, six parameters were collected and analyzed, including the time of finding, the position, the type of passing through the cortical bone, the special circumstances during operation (such as the need to remove the intramedullary nail for reaming the diaphysis, hammering, etc.), the treatment, and the patient follow-up results. Results In the 9 patients, the off target of the distal interlocking screw was found in 7 cases during operation and in 2 cases after operation; the locking screw was located behind the nail in 7 cases and in front of the nail in 2 cases; the off target locking screw was passing tangentially in transcortical patern in 6 cases and in bicortical pattern through the medullary cavity in 3 cases. Three cases were attributed to the mismatch between the nail and the femur, two of which were attributed to the narrow femoral medullary cavity, one of which was attributed to the large anterolateral femoral bowing, and the other 6 cases were attributed to technical errors such as the loosening of the jig-guided targeting device, the tension of the fascia lata, and the blunt of the drill. In the 7 cases found during operation, the misaligned interlocking screw was removed first and the screw hole was left vacant, then in 2 cases, the interlocking screw was not used further; in 1 case, the distal dynamic hole was successfully inserted with a dynamic guide frame, and in 4 cases, the interlocking screw was successfully put after 2-3 attempts, leaving a large hole in the lateral cortex. No special treatment was performed in 2 cases found after operation. One patient was out of bed early after operation, 7 patients were in bed for 1 month, and 1 patient deteriorated to A3 type after operation and was in bed for 3 months. All the 9 patients were followed up 6-12 months, with an average of 8 months. Fracture healing was achieved in 8 patients. One patient with vacant interlocking screw had a secondary spiral fracture of the femoral shaft 3 months later, and was refixed with a long cephalomedullary nail and circlage wiring. Conclusion Distal interlocking screw off target is rare, but when it occurs, it leaves a large cortical hole in the osteoporotic femoral shaft, reducing bone strength; the use of precision instruments and attention to technical details can reduce this adverse phenomenon.

Objective To summarize the new research progress in distal interlocking screws of cephalomedullary nails for the treatment of intertrochanteric fractures.

Results The mode of the distal interlocking screw holes can be divided into static and dynamic. Distal interlocking screws play the role of anti-rotation, maintaining femur length, resisting compression stress, increasing torque stiffness, resisting varus stress, etc. The number of the screws directly affects the toggling of the main nail in the cavity. At present, regardless of whether long or short nails are used, distal interlocking screws are routinely inserted in clinical practice. However, using distal interlocking screws can significantly increase the duration of anesthesia and operation, increase fluoroscopy exposure time, surgical blood loss, and incision length. There is a trend of trying not to use distal interlocking screws in recent years. No significant difference is found in some studies between the effectiveness of dynamic and static interlocking for AO/Orthopaedic Trauma Association (AO/OTA) 31-A1/2 fractures. At present, the selection of the number and mode of distal interlocking screws is still controversial. When inserting distal interlocking screws, orthopedists should endeavor to minimize the occurrence of complications concerning miss shot, vascular injuries, local stress stimulation, and peri-implant fractures. Conclusion Distal interlocking screws are mainly used to prevent rotation. For stable fractures with intact lateral walls, long cephalomedullary nails can be used without distal interlocking screws. For any type of intertrochanteric fractures, distal interlocking screws are required when using short cephalomedullary nails for fixation. Different interlocking modes, the number of interlocking screws, and the application prospects of absorbable interlocking screws may be future research directions.

Abstract
GRAND FIX mesh-type plates and pins (Gunze, Kyoto, Japan) are thin, bioabsorbable fixation devices made of poly-L-lactide (PLLA) composite. These devices are new, and how best to use them in clinical practice remains to be determined. Thus, we describe our approach to rib fixation after thoracotomy in an aortic surgery using GRAND FIX mesh-type plates and pins. The advantage of our approach is that it is easy to perform, but careful attention should be paid to fix the ribs appropriately.

Abstract
BACKGROUND The primary aim of this study was to compare the radiographic parameters (nail insertion-point accuracy [NIPA] and fracture malalignment) of patients who had undergone tibial intramedullary nailing via the suprapatellar (SP) and infrapatellar (IP) approaches. The secondary aims were to compare clinical outcomes and patient-reported outcomes (PROs) between these approaches. METHODS All adult patients with an acute tibial diaphyseal fracture who underwent intramedullary nailing at a single level-I trauma center over a 4-year period (2017 to 2020) were retrospectively identified. The nailing approach (SP or IP) was at the treating surgeon's discretion. Intraoperative and immediate postoperative radiographs were reviewed to assess NIPA (mean distance from the optimal insertion point) and malalignment (≥5°). Medical records and radiographs were reviewed to evaluate the rates of malunion, nonunion, and other postoperative complications. The Oxford and Lysholm Knee Scores (OKS and LKS) and patient satisfaction (0 = completely dissatisfied, 100 = completely satisfied) were obtained via a postal survey at a minimum of 1 year postoperatively. RESULTS The cohort consisted of 219 consecutive patients (mean age, 48 years [range, 16 to 90 years], 51% [112] male). There were 61 patients (27.9%) in the SP group and 158 (72.1%) in the IP group. The groups did not differ in baseline demographic or injury-related variables. SP nailing was associated with superior coronal NIPA (p < 0.001; 95% confidence interval [CI] for IP versus SP, 1.17 to 3.60 mm) and sagittal NIPA (p < 0.001; 95% CI, 0.23 to 0.97 mm) and with a reduced rate of malalignment (3% [2 of 61] versus 11% [18 of 158] for IP; p = 0.030). PROs were available for 118 of 211 patients (56%; 32 of 58 in the SP group and 86 of 153 in the IP group) at a mean of 3 years (range, 1.2 to 6.5 years). There was no difference between the SP and IP groups in mean OKS (36.5 versus 39.6; p = 0.246), LKS (71.2 versus 73.5; p = 0.696), or satisfaction scores (81.4 versus 79.9; p = 0.725). CONCLUSIONS Compared with IP nailing, SP nailing of tibial shaft fractures was associated with superior NIPA and a reduced rate of intraoperative malalignment but not of malunion at healing. However, the superior NIPA may not be clinically important. Furthermore, there were no differences in PROs at mid-term follow-up. LEVEL OF EVIDENCE Therapeutic Level III .

Abstract
OBJECTIVES To compare the outcomes of a minimally invasive reduction (MIR) technique using a cable and wire in spiral or oblique subtrochanteric femoral fractures (SFFs). METHODS DESIGN Retrospective cohort study. SETTING Two University Hospitals. PATIENT SELECTION CRITERIA Skeletally mature patients with spiral or oblique SFFs (OTA/AO 32A1 and 32A2) treated with intramedullary nailing and MIR with a cerclage wire passer using either a single-loop cable or cerclage wire or MIR without cable or wire between May 2016 and November 2021 were included. OUTCOME MEASURES AND COMPARISONS Coronal and sagittal interfragmentary gap, neck-shaft angle, coronal and sagittal angulation, fracture union, time to union, and Radiographic Union Score for Hip (RUSH) at 6 months post operation were compared. RESULTS A total of 46 patients were included, with 16 each in the cable and wire groups and 14 in the non-wiring group. There were no differences in demographics ( P > 0.05), fracture classification ( P = 0.710), or operative data ( P > 0.05) between the three groups. The cable group showed significantly better coronal ( P = 0.003) and sagittal ( P = 0.003) interfragmentary gap, shorter union time ( P < 0.001), and higher 6-month RUSH score ( P < 0.001) among the three groups. There were no significant differences in outcome measures between the wire and non-wiring groups (all P > 0.05). No mechanical complications or reoperations were observed in all three groups. CONCLUSIONS Minimally invasive reduction using a cable is more effective than wire or non-wiring reduction to improve reduction quality and promote bone union in the SFFs.

Abstract
The objective of this study was to measure how much of the superolateral femoral neck should be removed to reduce the incidence of wedge effect. Simulating surgery: Computed Tomography images of 131 intertrochanteric fracture patients were included, three-dimensionally reconstructed, virtually reduced and implanted with Proximal Femoral Nail Antirotation blade-Ⅱ(PFNA-Ⅱ) nail. The antero-posterior length and media-lateral width of the intersection between superolateral femoral neck and PFNA-Ⅱ nail were measured. Retrospective study: The pre- and postoperative CT of 30 patients were collected. The average varus angle of the neck-shaft angle and the correlation between the angles and the difference in the actual and estimated width of the fragments removed were measured. Models of 108 patient were selected for analysis. The average antero-posterior length and media-lateral width were 14.46 mm (14.00-14.93 mm) and 9.33 mm (8.79-9.87 mm), respectively. The AO/OTA classification was not significantly associated with the outcome, but the gender was. In the retrospective study, the mean value of the varus angles was -4.58° (SE = 6.85°), and the difference of width was strongly positively correlated with the varus angle with a correlation coefficient of 0.698. Results obtained in this study can improve the understanding of this region and help surgeons to make appropriate preoperative planning to reduce the incidence of wedge effect. Retrospective study provided effective proof of the reliability of this study.

Abstract
BACKGROUND There are clear standards for when to operate on both distal epiphyseal and diaphyseal forearm fractures in children. However, paediatric surgeons are often faced with fractures in the transition zone between metaphysis and diaphysis. This aim of the study is to compare different treatment approaches for diametaphyseal forearm fractures, to classify different types of these fractures, and to define further assessment parameters and treatment recommendations. METHODS This retrospective study included all patients with diametaphyseal radial fractures who were seen at a paediatric surgery clinic between 01.01.2010 and 31.12.2013. Patients were treated either non-surgically (C) or surgically using bicortical Kirschner wire (BC-KW), intramedullary K-wire (IM-KW), elastic stable intramedullary nailing (ESIN), or combined bicortical and intramedullary K-wire (BCIM-KW). RESULTS During the study period, 547 patients presented with forearm fractures of which 88 patients (16%) had a fracture in the diametaphyseal region. The majority of diametaphyseal fractures were greenstick fractures (54.4%) followed by transverse fractures (44.3%). Distal fractures were predominantly treated with bicortical K-wiring (BC-KW, 40.5%) or non-surgically (C, 26.2%). Proximal fractures were treated by ESIN osteosynthesis (50%), followed by IM-KW (30%). Intermediate fractures were just as likely to be treated with one out of the 5 above-mentioned techniques. The ulna was involved in 64 of 88 cases. Depending on the type of fracture, it was treated either by ESIN osteosynthesis or non-surgically. No superior operative technique was identified. CONCLUSIONS The description of diametaphyseal fractures as a separate entity is important, because the therapy of these fractures is heterogeneous and challenging. A classification into proximal, intermediate, and distal may be useful in clinical decision-making. Despite the retrospective nature of this study, our data suggest that the use of a K-wire or combined technique BCIM-KW-technique, whenever technically feasible, achieves better radiological results without secondary dislocation. Further prospective studies are needed to provide better guidance to trauma surgeons.

Abstract
We assessed the radiological and functional results of pediatric both-bone forearm diaphyseal fractures treated using elastic stable intramedullary nails (ESINs), as well as factors affecting the results. In total, 36 patients (33 males and three females; mean age, 11.6 years) were included. The mean follow-up time was 41.5 (18-96) months. Patient demographic characteristics and the details of the surgical techniques were analyzed retrospectively. In addition to standard radiographic evaluations, the ratio between the nail diameter and medullary canal diameter (ND/MCD) was measured, as well as the maximal radial bowing. According to the criteria of Price and Flynn, 28 (77.8%) and eight (22.2%) patients had excellent and good results, respectively. There were no cases of nonunion or delayed union. There was no significant difference in functional or radiological results according to whether titanium nails (24 patients) or stainless steel nails (12 patients) were used (all P > 0.05). Nail prebending (performed in 19 patients) did not affect the functional or radiological results ( P > 0.05). Loss of reduction was observed in four patients with an ND/MCD ratio <40%. The maximal radial bowing improved in all patients. The mean change was significantly greater in patients with diastases and 22D/4.1 fractures. Regardless of nail type or prebending status, surgery using ESIN placement effectively treats both-bone forearm diaphyseal fractures; radial bow remodeling outcomes are excellent. We recommend that the ND/MCD ratio should be 40-70%.

Abstract
Aims As an alternative to external fixators, intramedullary lengthening nails (ILNs) can be employed for distraction osteogenesis. While previous studies have demonstrated that typical complications of external devices, such as soft-tissue tethering, and pin site infection can be avoided with ILNs, there is a lack of studies that exclusively investigated tibial distraction osteogenesis with motorized ILNs inserted via an antegrade approach. Methods A total of 58 patients (median age 17 years (interquartile range (IQR) 15 to 21)) treated by unilateral tibial distraction osteogenesis for a median leg length discrepancy of 41 mm (IQR 34 to 53), and nine patients with disproportionate short stature treated by bilateral simultaneous tibial distraction osteogenesis, with magnetically controlled motorized ILNs inserted via an antegrade approach, were retrospectively analyzed. The median follow-up was 37 months (IQR 30 to 51). Outcome measurements were accuracy, precision, reliability, bone healing, complications, and patient-reported outcome assessed by the Limb Deformity-Scoliosis Research Society Score (LD-SRS-30). Results A median tibial distraction of 44 mm (IQR 31 to 49) was achieved with a mean distraction index of 0.5 mm/day (standard deviation 0.13) and median consolidation index of 41.2 days/cm (IQR 34 to 51). Accuracy, precision, and reliability were 91%, 92%, and 97%, respectively. New temporary range of motion limitations occurred in 51% of segments (34/67). Distraction-related equinus deformity treated by Achilles tendon lengthening was the most common major complication recorded in 16% of segments (11/67). In 95% of patients (55/58) the distraction goal was achieved with 42% unplanned additional interventions per segment (28/67). The median postoperative LD-SRS-30 score was 4.0 (IQR 3.6 to 4.3). Conclusion Tibial distraction osteogenesis using motorized ILNs inserted via an antegrade approach appears to be a reliable and precise procedure. Temporary joint stiffness of the knee or ankle should be expected in up to every second patient. A high rate and wide range of complications of variable severity should be anticipated.

Abstract
BACKGROUND Lag screw cutout is a devastating complication after internal fixation of an intertrochanteric fracture. Although the tip-apex distance (TAD) is known to be associated with this complication, another factor we thought was potentially important-fracture reduction on an oblique lateral view-has not, to our knowledge, been explored. QUESTIONS/PURPOSES (1) Is a well-reduced fracture position on an oblique lateral view after internal fixation of intertrochanteric fracture associated with a lower odds of postoperative cutout, independently of the TAD? (2) Is postoperative sliding of the lag screw after fixation associated with postoperative cutout? METHODS Patients with intertrochanteric fractures who were at least 65 years old and who had been treated with internal fixation in one of six facilities between July 2011 and December 2017 were included. All patients in the study group had lag screw cutout, and controls were selected by risk-set sampling of age-matched and sex-matched patients using a ratio of 4:1 for patients from each hospital. Of the 2327 intertrochanteric fractures, there were 36 patients (0.02 per person-year), with a mean age of 85 years; 89% (32) were women. In the control group, there were 135 controls. There was no difference in age or sex between the two groups. Sagittal reduction was evaluated using an immediate postoperative oblique lateral radiograph (anterior malreduction versus anatomic reduction or posterior malreduction). The association between anterior malreduction and the odds of cutout was estimated by conditional logistic regression analysis with the TAD and interaction between the TAD and the reduced position as covariates. As a sensitivity analysis, we estimated whether sliding within 2 weeks postoperatively was associated with cutout. RESULTS After controlling for the potentially confounding variables of age and sex, we found that anterior malreduction was independently associated with a higher odds of cutout compared with anatomic reduction or posterior malreduction (adjusted OR 4.2 [95% CI 1.5 to 12]; p = 0.006). There was also an independent association between cutout and larger TAD (≥ 20 mm) (adjusted OR 4.4 [95% CI 1.4 to 14]; p = 0.01). However, the association between cutout and reduction was not modified by the TAD (adjusted OR of interaction term 0.6 [95% CI 0.08 to 4]; p = 0.54). Postoperative sliding ≥ 6 mm within 2 weeks was associated with higher odds of cutout after adjusting for age and sex (adjusted OR 11 [95% CI 3 to 40]; p < 0.001). CONCLUSION In patients older than 65 years with intertrochanteric fractures, anterior malreduction on a lateral oblique view was associated with much greater odds of postoperative cutout than anatomic reduction or posterior malreduction. Because anterior malreduction is within the surgeon's control, our findings may help surgeons focus on intraoperative reduction on an oblique lateral view to prevent cutouts. Although this factor is a reliable indicator, the results should be applied to cephalomedullary nails, because there was only one patient with cutout among those with sliding hip screws. Because this study was conducted in a homogenous Japanese population, future studies should focus on the association between anterior malreduction and cutout in people of different ethnicities, adjusting for confounding factors such as implant type and surgeon level. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Charcot reconstruction with static external fixation provides stability in deformity correction. Concern for pin site health remains forefront to prevent premature fixator removal should infection develop. While previous investigations examined a spectrum of pin care protocol with a similar variation in outcomes, this study assesses results following a "no care pin care" routine. A retrospective analysis of patients with Charcot neuroarthropathy treated with static external fixation was performed where all pin sites were dressed using a chlorhexidine-soaked sponge without postoperative maintenance. Demographics, reconstruction-specific, and postoperative variables including pin site irritation, pin site infection, and pin tract infection were collected through frame removal. A comparison between uncomplicated and complicated pin sites was made. Statistical significance was set as p ≤ .05. Among 85 patients and their respective pin holes that posed potential spots of infection, 6 (7%) experienced pin site irritation and 5 (6%) experienced pin site infection. Moreover, 2 (2%) experienced a pin tract infection requiring removal. Out of the 768 wires/half-pins 2 (0.3%) were removed. There existed no statistically significant predictors of pin site irritation/infection other than age (p = .03). "No care pin care" proves an effective means at pin site care following static external fixation in Charcot reconstruction. Limited maintenance reduces the postoperative burden on providers and patients.

Abstract
BACKGROUND Intramedullary nailing (IMN) is considered the gold-standard treatment for femoral shaft fractures. The post operative fracture gap is commonly recognized as a risk factor for nonunion. However, no evaluation standard for measuring the fracture gap size has yet been established. In addition, the clinical implications of the fracture gap size have also not been determined so far. This study aims to clarify how we should evaluate fracture gaps when assessing simple femoral shaft fractures with radiographs and to determine the acceptable cut-off value of the fracture gap size in simple femoral shaft fractures. METHOD A retrospective observational study with a consecutive cohort was conducted at the trauma center of a university hospital. We investigated the fracture gap using postoperative radiography and the postoperative bone union of transverse and short oblique femoral shaft fractures fixed by IMN. The receiver operating characteristic curve analysis was conducted to obtain the fracture gap's mean, minimum, and maximum cut-off values. Fisher's exact test was used at the cut-off value of the most accurate parameter. RESULTS In the four nonunions among the 30 cases, the analysis using ROC curves revealed that the maximum value had the highest accuracy among the maximum, minimum, and mean values of fracture-gap size. The cut-off value was determined to be 4.14 mm with high accuracy. Fisher's exact test showed that the incidence of nonunion was higher in the group with a maximum fracture gap of 4.14 mm or greater (risk ratio = not applicable, risk difference = 0.57, P = 0.001). CONCLUSION In simple transverse and short oblique femoral shaft fractures fixed with IMN, the fracture gap on radiographs should be evaluated by the maximum gap in the AP and lateral views. The remaining maximum fracture gap of ≥4.14 mm would be a risk factor for nonunion.

Abstract
INTRODUCTION The purpose of this study was to determine whether there have been changes in the numbers and complexity of femoral fragility fractures presenting to our department over a period of 10 years. METHODS Patients >60 years presenting with femoral fragility fractures to our institution in 2018-2019 (397 fractures) were compared with respect to demographic data, incidence rates, fracture classification and surgical management with a historical cohort from 2009-2010 (335 fractures). Pathological and high velocity fractures were excluded. RESULTS The gender proportion and average age (83.1 vs. 82.7 years) was unchanged. The number of femoral fractures increased by 19% but the overall incidence in people >60 years fell by 6% (p = 0.41). The proportion of unstable trochanteric fractures (31A2 and A3) increased from 22% to 55% (p < 0.001). The proportion of displaced intracapsular fractures increased from 53% to 72% (p < 0.001). The incidence of stable trochanteric fractures fell from 12.4 to 7.3/10,000 patients>60 years (p = 0.0006) while the incidence of unstable trochanteric fractures (31A2 and 31A3) increased from 3.5 to 8.9/10,000 patients >60 years (p < 0.0001). The proportion of trochanteric fractures treated with an intramedullary (IM) nail increased from 9% to 35% (p = 0.0001). The number of shaft and distal femoral fractures increased by 41% although the incidence did not change significantly. Periprosthetic fractures comprised 70% of femoral shaft fractures in both cohorts. CONCLUSIONS The increasing number and complexity of femoral fragility fractures, especially unstable trochanteric fractures and periprosthetic fractures, is likely to have an impact on implant use, theatre time and cost.
