Abstract
OBJECTIVE The objectives of this study were to: (1) determine all the potential risk factors defined in the literature for cut-out after proximal femoral nail anti-rotation in managing intertrochanteric fractures and (2) make a reliable prediction about the likelihood of cut-out by developing a quantitative scoring system. METHODS Four hundred eighty patients who were operated on for an intertrochanteric femur fracture were included in the study. The patients were evaluated retrospectively. Radiological parameters known to affect cut-out, including tip apex distance (TAD), calcarreferenced TAD (CalTAD), and reduction quality, were also used to evaluate the patients. Additionally, the classification of the fracture according to the cortical thickness index for osteoporosis, the Charlson comorbidity index for additional comorbidities, and the Arbeitsgemeinschaft Für Osteosynthesefragen classification were evaluated. RESULTS The cut-out rate among all patients was 7.2%. Cut-out risk could be predicted by gender, TAD, CalTAD, and reduction quality. Female gender, TAD > 29.45, CalTAD > 31.75, and acceptable or poor reduction quality significantly increased the cut-out risk. Based on the chi-square analysis, it was determined that there was a significant relationship between the cut-out risk and the variables of TAD, CalTAD, reduction quality, gender, and fracture type (P=.000, P=.000, P=.000, P=.008, P=.016, respectively). Logistic regression analysis showed a strong correlation between the newly developed scoring system and the risk of cut-out. The risk of cut-out increased 8.1 times in individuals with a score of more than 2 (P < .001). CONCLUSION Female gender, TAD > 29.45, CalTAD > 31.75, and acceptable or poor reduction quality are the parameters found to be significant in determining the cut-out risk. With the newly developed scoring system, risks can be calculated for all situations that may occur according to the scores obtained by the patients. The cut-out risk increases significantly in patients with a score above 2 points. LEVEL OF EVIDENCE Level III, Diagnostic Study.

Abstract
BACKGROUND AND PURPOSE The Lubinus SP2 stem has been associated with a very low risk of periprosthetic femoral fractures (PPFFs). We aimed, primarily, to study the radiographic morphology of PPFFs close to a Lubinus SP2 stem. Secondarily, we analyzed whether higher reoperation rate was correlated to the revision method chosen or to the characteristics of the fracture and of the bone. PATIENTS AND METHODS The study included 156 femoral fractures close to a Lubinus cemented stem. These fractures were treated in 40 hospitals in Sweden between 2006 and 2011 and were followed up until 2019. Data from the Swedish Arthroplasty Register was used. Medical records and radiographs were studied. The fractures were classified according to the Vancouver classification. The fracture location and anatomy were delineated. We also measured the remaining attachment index (RAI) and the canal thickness ratio. RESULTS Vancouver type C (n = 101) and spiral fractures (n = 67, 41 in Vancouver C and 26 in Vancouver B) were the most common fracture types. 4 fractures were avulsion of the greater trochanter. The remaining 51 fractures occurred around the stem (B1: 25, B2: 16, and B3: 10). B fractures were more commonly reoperated on (18 of 51, 35%) than type C fractures (11 of 101, 11%, P = 0.001). In most femurs with type B3 fracture, the fracture line covered an area only around the stem, but in all B1 and in 11 of 16 B2 fractures, it was extended even distal to the stem. ORIF instead of stem revision in B2 fractures, use of short stems or plates, and inadequate reduction of the fractures were risk factors for subsequent reoperations. CONCLUSION The higher reoperation rate in type B fractures, compared with fractures distal to the stem, could be caused by their higher degree of complexity and reduced capacity for healing in the region around the stem.

Abstract
A traumatic femur fracture is a significant cause of morbidity, affecting one to three million individuals annually. The present is the first study investigated the epidemiological characteristics, risk factors, classification, mechanisms of injury, and early management of femoral fractures in Somalia. This retrospective epidemiological study included all patients with a femur fracture who were admitted for four years between November 2018 and December 2022 to the orthopedic and trauma surgery department. We reviewed patient demographic characteristics, including age and gender, the mechanism of injury, injury characteristics, and the type of fixation performed. We reviewed the radiographs and classified the fracture using the AO/OTA classification system. During the study period, a total of 402 patients were treated for femur fractures; 256 (64%) were males, and 144 (36%) were females. The mean patient age was 47.7 ± 8.5 years. Regarding the anatomical location of femur fractures, the proximal (31A, 31B) was the most common, accounting for 50% of the patients. Femur neck fracture (31B) was the most common in the proximal femur fractures. Gunshot 82 (59.42%) was the leading cause of femur shaft fractures. Most patients with femur shaft fractures were males; 150 (86.20%) and 152 (64.47%) were young patients between 19 and 40 years old. Almost half of the patients (86) with femur shaft fractures had open fractures. The distribution of the mechanism of injury significantly differed according to age (p < 0.001). Younger patients (< 40 years) were predominantly injured due to gunshot injuries compared to elderly cases (> 60 years), where falls from standing height were the primary mechanism of injuries. There was a statistically significant difference between the mechanism of injury and gender categories (p < 0.001). Male patients were injured mainly by gunshots in about 40%, while 80% of fractures in female patients were due to falls from standing height. Female fractures occurred primarily in the proximal, while the males had an equal fracture rate for proximal and shaft fractures. Femur fracture causes significant morbidity and mortality. The study findings revealed that the most common femur fracture type was femur neck fracture, and low-energy injuries were the most common mode of injury in the elderly. Proximal femur fractures occur in older age and mainly in females. Gunshots were the most common cause of femur shaft fractures in Somalia, a country that has struggled with wars for over 30 years.

Abstract
BACKGROUND AND PURPOSE Premature physeal closure (PPC) is a common and concerning complication to distal femoral fractures as the distal growth plate accounts for 70% of the growth of the femur. The literature is not unanimous in determining the risk factors of PPC, and the epidemiological characterization of these fractures is limited. Our aim was to calculate the population-based incidence and investigate risk factors for PPC in these fractures. PATIENTS AND METHODS In this register-based study, between 2014 and 2021, 70 children with distal femoral physeal fractures presented to our hospital. Demographic data, and fracture- and treatment-related details were collected using the Kids' Fracture Tool. A directed acyclic graph (DAG) was constructed to determine confounding factors used in the risk analysis. RESULTS Physeal fractures of the distal femur occurred with an annual incidence of 6/105 children, and a resulting PPC occurred in 16/70 (23%) with an annual incidence of 1.3/105 children. In multivariable analysis, dislocation exceeding 10 mm was a risk factor for PPC (OR 6.3, CI 1.4-22). CONCLUSION One-fourth of distal femoral physeal fractures developed PPC. Greater dislocation and higher injury energy were significant risk factors, whereas choice of fracture treatment was not an independent risk factor. All patients with PPC belonged in the age group 11-16 years.

Abstract
CASE In the setting of a total hip arthroplasty performed in a patient with a proximal femoral deformity, atraumatic periprosthetic femoral stress fracture may arise as a complication. We report a rare case of a late periprosthetic femoral stress fracture around a cemented stem in a patient with a history of fibrous dysplasia of the proximal femur. After a 10-year uneventful period, the patient complained about a subtle, subacute pain in his left thigh induced by exercise but not with daily axial load. Diagnosis of a nondisplaced, incomplete (i.e., only compromising the lateral femoral cortex) periprosthetic femoral stress fracture was made with plain radiographs, blood work, and bone scintigraphy. Surgical treatment consisted of a minimally invasive plate osteosynthesis bridging the femoral deformity plus percutaneous osteoperiosteal decortication. At 5-year follow-up, the patient was asymptomatic with full return to physical activity, with radiographs evidencing callus formation. CONCLUSION Stress fractures around well-fixed femoral stems, while infrequent, should be addressed in patients with a history of severe proximal femur deformity experiencing atraumatic thigh pain.

Abstract
INTRODUCTION The aim of this study was to evaluate the clinical and radiological outcomes of patients treated with the TFN-Advanced™ Proximal Femoral Nailing system (TFNA¸ DePuy Synthes, West Chester, PA) including intra- and postoperative complications. MATERIALS AND METHODS All patients with an acute proximal femur fracture consequently treated with a TFNA between September 2014 and December 2018 were evaluated. Clinical and radiological data were assessed for intra- and postoperative complications, including treatment failure. In addition, intra- and postoperative X-rays were used to determine the position of the implant, and any migration, via tip-apex-distance (TAD) and the caput-collum-diaphyseal angle (CCD). The accuracy of the fracture reduction was rated by both observers according to Baumgartners criteria. RESULTS 275 consecutive patients (mean age 77.5 ± 14.1; 70.2% female) were included. The predominant OTA/AO fracture classification was 31A2 (140 cases, 50.7%). The average surgical time was 69 min (± 39.8). The reduction quality was good in 253 cases (92.0%) and acceptable in 22 cases (8.0%). In 18 cases, a pre-defined primary outcome parameter (6.5%) was recorded after a mean of 8.2 ± 8.0 months. During the observational period, 19 patients (6.9%) required a total of 23 additional surgeries. Implant removal was not considered a failure in the absence of pain. Significant group differences were observed with younger age (p = 0.001), lower Charlson Comorbidity Index (CCI)-score (p = 0.041) and lower rate of osteoporosis (p = 0.015) in the failure group. There were no cases of cut-out or cut-through among the patients who underwent augmentation as part of osteosynthesis. CONCLUSIONS Proximal femur fractures treated with the TFNA show low complication rates and high levels of radiological healing. Implant-related complications might be more common in patients with younger age, a lower CCI-score and lower frequency of osteoporosis. Usage of cement augmentation could potentially be beneficial to reduce postoperative cut-through and cut-out.

Abstract
Introduction Elastic stable intramedullary nailing (ESIN), developed by the Nancy school in France, is the gold standard for surgical treatment of long bone fractures in children. In Africa, few works have been devoted specifically to this technique. Objective This study aimed to describe the outcome and to present the challenges with this technique in the treatment of long bone fractures in children. Patients and Methods This was a prospective and descriptive study over 4 years including patients aged 0-15 years old operated using ESIN. Results Sixty-two patients underwent ESIN, of whom 44 patients (70.96%) were for femur fractures, nine patients (14.52%) for tibia and fibula fractures and nine patients (14.52%) for humerus fractures. The majority of the patients treated with ESIN were children older than 6 years. Nine patients (14.51%) and 13 patients (20.98%) underwent ESIN following polytrauma and multiple fractures, respectively. Seven patients (11.29%) were operated on through-closed ESIN method. The unavailability of image intensifier (38.71%) and the presence of bone callus (40.32%) were the major reasons for using the open ESIN method. Thirty-three patients (53.23%) had minor or major complications. The majority of patients had satisfactory therapeutic outcomes. Conclusion ESIN gives good results, even when the fracture site is approached.

Abstract
BACKGROUND The treatment modalities for pediatric femoral shaft fractures are determined by their age, weight, and fracture pattern. Rigid intramedullary nailing (RIN) is usually recommended for patients >11 years of age, and elastic intramedullary nailing (EIN) has been used for patients under 10 years. However, little is known about the use of RIN in patients aged 8 to 10 years. We examined the differences in patients with femoral shaft fractures who were treated with EIN or RIN in terms of (1) fracture healing; (2) changes of anatomic parameters; and (3) related complications. METHODS We retrospectively reviewed 54 patients between 8 and 10 years of age, with femoral shaft fractures, who were treated with either EIN or RIN between 2011 and 2020. Lateral trochanteric entry was used for RIN procedure. The mean follow-up period was 26.4 months (range, 6 to 113 mo). There were 17 patients in the EIN group and 37 patients in the RIN group. The mean age at the time of surgery was 1 year younger in the EIN group ( P <0.01). The mean weight of the patient was significantly heavier in the RIN group compared with the EIN group. RESULTS Complete union of the fracture was achieved slightly faster in the RIN group at 3.4 months compared with 3.7 months in the EIN group ( P =0.04). There were no clinically significant changes of the anatomic parameters in either group, including neck shaft angle and articulotrochanteric distance. There was no evidence of avascular necrosis at the time of final follow-up for either group. There were no significant differences in postoperative complications between the groups. CONCLUSION RIN using lateral trochanteric entry is a feasible surgical option for femoral shaft fractures in patients 8 to 10 years of age that are heavier than 40 kg or with unstable fracture patterns.

Abstract
OBJECTIVES To determine patient, fracture, and construct related risk factors associated with nonunion of distal femur fractures. DESIGN Retrospective cohort study. SETTING Academic Level I trauma center. PARTICIPANTS Patients 18 years and older presenting with OTA/AO 33A and 33C distal femur fractures from 2004 to 2020. A minimum follow-up of 6 months was required for inclusion. OTA/AO 33B and periprosthetic fractures were excluded, 438 patients met inclusion criteria for the study. MAIN OUTCOMES The primary outcome of the study was fracture nonunion defined as a return to the OR for management of inadequate bony healing. Patient demographics, comorbidities, injury characteristics, fixation type, and construct variables were assessed for association with distal femur fracture nonunion. Secondary outcomes include conversion to total knee arthroplasty, surgical site infection, and other reoperation. RESULTS The overall nonunion rate was 13.8% (61/438). The nonunion group was compared directly with the fracture union group for statistical analysis. There were no differences in age, sex, mechanism of injury, Injury Severity Score, and time to surgery between the groups. Lateral locked plating characteristics including length of plate, plate metallurgy, screw density, and working length were not significantly different between groups. Increased body mass index [odds ratio (OR), 1.05], chronic anemia (OR, 5.4), open fracture (OR, 3.74), and segmental bone loss (OR, 2.99) were independently associated with nonunion. Conversion to total knee arthroplasty (TKA) ( P = 0.005) and surgical site infection ( P < 0001) were significantly more common in the nonunion group. CONCLUSION Segmental bone loss, open fractures, chronic anemia, and increasing body mass index are significant risk factors in the occurrence of distal femoral nonunion. Lateral locked plating characteristics did not seem to affect nonunion rates. Further investigation into the prevention of nonunion should focus on fracture fixation constructs and infection prevention. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
BACKGROUND Anterior femoral cortical impingement and perforation are known risks of cephalomedullary nailing. The incidence of and risk factors for these findings have not been fully established in the literature. The purpose of this review was to answer: (1) What is the incidence of anterior femoral cortical impingement and perforation associated with cephalomedullary nailing of proximal femur fractures? (2) How does incidence vary by nail radius of curvature (ROC)? (3) What populations are at increased risk of impingement and perforation? (4) What surgical techniques prevent their occurrence? HYPOTHESIS Our hypothesis was that impingement would be a relatively common finding following cephalomedullary nailing, and perforation would be much less frequent but still an appreciable risk. Secondarily, nails with a larger ROC would have a higher rate of impingement. PATIENTS AND METHODS In this systematic review, PubMed, MEDLINE, and Cochrane databases were searched for articles from 1990-2020 written in English using the terms "cephalomedullary nail" or "femoral nail" and "perforation" or "impingement", and similar words. Inclusion criteria were studies discussing the complication of anterior femoral cortical impingement or perforation associated with the use of a cephalomedullary nail. Fourteen studies met inclusion criteria. Rates of anterior femoral cortical impingement or perforation, patient demographics, nail type, and ROC were extracted. Surgical techniques to prevent perforation were qualitatively reviewed. RESULTS The rate of anterior cortical impingement with long cephalomedullary nails was 17.2% (192/1117 patients) and with short nails was 29.2% (176/602). The rate of anterior cortical perforation with long nails was 1.0% (11/1116) and with short nails was 0% (0/234). Long nails with ROC>150cm showed an impingement rate of 10.9% (62/567) and perforation rate of 1.1% (7/617 patients). Nails with ROC 150cm or 100cm had an impingement rate of 1.1% (1/93) and perforation rate of 0% (0/93). DISCUSSION Impingement and perforation of the anterior femoral cortex during cephalomedullary nailing are appreciable risks that surgeons should anticipate and avoid, especially in certain populations and with nails with larger ROC. Surgeons may consider use of long nails with ROC 150cm and below, given a nearly 10-fold lower incidence of impingement and no reported perforations. LEVEL OF EVIDENCE Therapeutic, level IV.

Abstract
With a growing number of patients undergoing total knee replacements globally, coupled with an elderly population, the incidence of periprosthetic fractures around total knee replacements is increasing. As such, this is a highly topical subject that is gaining increasing interest within the orthopaedic community. This review provides a narrative synthesis of the most contemporary literature regarding distal femoral periprosthetic fractures. We review the related epidemiology, initial patient evaluation, the evolution and relevance of the classification systems and treatment options, particularly related to endoprosthetics and hybrid fixation constructs. The latest orthopaedic evidence related to this topic has been included.

Abstract
AIMS To compare in a prospective randomized trial the mechanical complications in patients with unstable extracapsular proximal femur fractures without subtrochanteric extension (AO/OTA 31-A2 and 31-A3) METHODS: We prospectively studied 182 patients with unstable extracapsular proximal femur fractures without fractures lines extending more than 3 cm below the lesser trochanter, randomized to receive either a 'standard' (240 mm) nail or a long nail and followed them up for 1 year. RESULTS We found no difference in the incidence of mechanical or general complications between the two groups, no cut-outs, no fractures of the tip the implant, 1 cut-through and 2 malrotations in the LN group, 2 non-unions that were reoperated, one on each group. The commonest complication was blade lateral migration, 13 (14%) patients in SN and 6 (9%) in the LN. The operating time was shorter in the SN group 51 minutes compared to 67 minutes in the LN group (p=0.000075). The mortality at 1,3 and 12 months in the SN group was of 2%, 6%, 12% while in the LN group was 12%, 18% and 22%. These differences where significative at 1 (p=0.007) and 3 months (p=0.013), but not at 12 months (p=0.075). CONCLUSIONS We recommend the use of standard nails (240 mm) for this group of fractures, since it does not produce more mechanical complications, and it is faster, cheaper and easier to interlock distally.

Abstract
OBJECTIVE To analyze leg length discrepancy and overgrowth after tibial shaft fractures in children. MATERIAL AND METHODS We analyzed medical records of 103 patients younger 14 years old with tibial shaft fractures between January 2003 and November 2018. Treatment included plastering and insertion of titanium elastic nail. To identify the risk factors of leg length discrepancy ≥1 cm and overgrowth ≥1 cm, we performed logistic regression analysis. Statistical analysis was carried out using the SPSS software for Windows. RESULTS Gender (p=0.014) and treatment methods (p=0.011) are the most significant predictors of leg length discrepancy and overgrowth. In boys, the risk of leg length discrepancy ≥1 cm was 7.4 times higher than in girls. The risk of leg length discrepancy ≥1 cm was 4.3 times higher after insertion of titanium elastic nail compared to plastering. The risk of overgrowth ≥1 cm was 5.4 times higher in boys than in girls. The risk of overgrowth ≥1 cm was 4.7 times higher after insertion of titanium elastic nail compared to plastering. CONCLUSION One should consider the risk of leg length discrepancy and overgrowth in children with tibial shaft fractures. This is especially true for boys undergoing insertion of titanium elastic nail.

Abstract
PURPOSE OF THE STUDY The primary aim is to assess the proportion of children younger than two years with a femoral fracture who underwent a skeletal survey. The secondary aim of the study is to evaluate the patients' demographics, reported trauma mechanism, type of fracture, type of treatment and complication rate. MATERIAL AND METHODS This was a retrospective study of children younger than two years examined at the Department of Imaging Methods for a femoral fracture between 2015-2022. The type and site of the fracture were assessed on radiographs. The patients' medical records were used to assess which steps had been taken to evaluate for possible abusive etiology of the fracture. The data were correlated with the published guidelines for performing skeletal survey in young children with fractures. The patients' demographics, medical history, time interval from trauma or symptoms onset to medical examination, type of treatment, duration of orthopaedic follow-up in addition to the clinical fi ndings at the last orthopaedic follow-up visit were also retrieved from the patients' medical records. RESULTS A total of 40 children were included in the study, 21 of whom were girls (52.5%). The mean age was 13.8 months. 5 children (12.5 %) were younger than 6 months. 36 children (90%) had a history of trauma, the vast majority of whom suffered a fall. 21 patients (52.5%) sustained a distal metaphyseal fracture, 19 patients (47.5%) suffered a diaphyseal fracture. A spica cast was used in 12 patients (30%), which was applied under general anaesthesia in most cases. 28 patients (70%) received a long leg cast. A certain degree of stiffness following cast removal was the only documented complication. Based on the published guidelines, it was estimated that in 23 patients (57.5%) a skeletal survey should have been performed. However, this investigation was performed in 2 patients (5%) of the study population only. DISCUSSION Femoral fractures in young children are rare, especially in those younger than six months of age. The fractures were located in femoral diaphysis and in distal femoral metaphysis. Surgical treatment was not required, and no signifi cant complications were observed. Nonetheless, the study showed that the rate of child abuse screening was low. The skeletal survey was performed in two cases only, both children were younger than six months and had no history of trauma. Based on the published guidelines, however, it may be assumed that the skeletal survey should have been performed in more than half of the patients in the study. The failure to perform this investigation might have led to the abuse not being detected and the child being returned to the abusive environment. CONCLUSIONS Management of femoral fractures in patients younger than two years does not usually require hospitalisation and is not associated with the risk of complications. However, potential further harm may be caused if abusive etiology of the femoral fracture fails to be discovered. This study has shown that the rate of abuse evaluation is low. It is essential to initiate a multidisciplinary discussion on this topic to raise the physicians' awareness and to implement the screening for child abuse among young children with femoral fractures. This scientifi c paper also includes a summary of necessary steps to be taken in the evaluation of a young child with a femoral fracture.

Abstract
BACKGROUND Periprosthetic femoral fractures (PFFs) in total hip arthroplasty (THA), especially those in contact with the diaphyseal stem, carry high morbidity. This study evaluated how stem design influences the risk of early Vancouver B PFF or other PFF requiring operative intervention after THA. METHODS A multicenter, retrospective study of 3,433 primary cementless THAs performed from 2014 to 2021 included 2,302 single-taper (micro M/L [n = 1,169]; M/L [n = 1,133]) and 1,131 double-taper (fit-and-fill [n = 420]; compaction-collared [n = 711]) stems. Mean follow-up was 2.2 years (range, 0.3 to 6.5 years). Primary outcomes were Vancouver B and surgically treated postoperative PFFs among differing femoral stems. Secondary outcomes included rates of intraoperative and postoperative Vancouver A and C PFFs. RESULTS Forty five postoperative PFFs (1.3%) occurred within 8.8 weeks (median), 25 of which were Vancouver B (0.7%) and 20 total PFFs that required operative intervention (0.6%). Compaction-collared stems had a decreased risk of Vancouver B (hazard ratio 0.18, 95% confidence interval: 0.03-0.97 P = .044) and any surgically treated PFF (hazard ratio 0.10, 95% confidence interval: 0.01-0.95; P = .037). Intraoperative PFFs were most common with fit-and-fill stems (3.6%, P < .001) and Vancouver A with compaction-collared stems (1.8%, P < .001). The cohort with PFF had a higher Charlson comorbidity index (P = .004), more women (P = .001), more Dorr A or C femora (P = .013), and more posterior or lateral surgical approaches compared to those without PFF (P ≤ .001). CONCLUSION After controlling for confounding variables, compaction-collared stems had a significantly lower risk of postoperative Vancouver B and PFF requiring operative treatment than single-taper and double-taper stems.

Abstract
OBJECTIVE To determine if reamed intramedullary nailing (IMN) of tibial and femoral shaft fractures exacerbated the hypercoagulable state of COVID infection, resulting in increased thromboembolic and pulmonary complications. DESIGN Retrospective chart review. SETTING Eleven Level I trauma centers. PATIENTS From January 1, 2020, to December 1, 2022, 163 patients with orthopaedic trauma and COVID positivity and 36 patients with tibial and femoral shaft fractures were included. INTERVENTION Reamed IMN. MAIN OUTCOME MEASURES Incidence of postoperative thromboembolic and respiratory complications. RESULTS Thirty-six patients with a median age of 52 years (range, 18-92 years; interquartile range, 29-72 years) met criteria. There were 21 and 15 patients with femoral and tibial shaft fractures. There were 15 patients sustaining polytrauma; of which, 10 had a new injury severity score of >17. All patients underwent reamed IMN in a median of 1 day (range, 0-12 days; interquartile range = 1-2 days) after injury. Two patients developed acute respiratory distress syndrome (ARDS) and 3 pneumonia. No patients had pulmonary embolism, deep vein thrombosis, or died within 30 days. CONCLUSION In this multi-institutional review of COVID-positive patients undergoing reamed IMN, there were no thromboembolic events. All patients developing pulmonary complications (ARDS or pneumonia) had baseline chronic obstructive pulmonary disease, were immune compromised, or sustained polytraumatic injuries with new injury severity score of >20. Given this, it seems reasonable to continue using reamed IMN for tibial and femoral shaft fractures after evaluation for COVID severity, comorbidities, and other injuries. LEVELS OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
INTRODUCTION Femur fractures represent a major public health issue and are commonly treated by intramedullary nailing. Among the possible complications of this technique, the injury of the superior gluteal artery (SGA) is quite rare, but it must be promptly recognized and treated. CASE REPORT A 35-year-old male was admitted with a right femur diaphyseal fracture. After an early damage control surgery, he under-went a close reduction and long intramedullary nail fixation. During the post-operative rehabilitation, a sudden hip pain and hemoglobin drop occurred. A CT-scan showed an extensive hematoma; angiography confirmed a superior gluteal artery bleeding which was subsequently treated with selective embolization. DISCUSSION AND CONCLUSION Whenever a patient presents with postoperative suspect of active bleeding, it is important to consider even the rarest complications. Sharing our experience in the management of a SGA lesion case, we want to stress the importance of its early diagnosis and correction, since it can represent a life-threatening condition.

Abstract
PURPOSE This study aimed to evaluate the outcomes of dual plating for unstable distal femoral fractures via a subgroup analysis between periprosthetic and non-periprosthetic fractures. METHODS This retrospective cohort study analyzed the outcomes of dual plating for unstable distal femoral fractures among 49 consecutive patients (43 women and 6 men) enrolled from July 2008 to August 2020. The patients were divided into periprosthetic (group P, n = 29) and non-periprosthetic (group N, n = 20) groups. The radiographic outcomes included the mechanical lateral distal femoral angle (mLDFA) and union rate based on the computed tomography findings. The clinical parameters included the knee range of motion and knee society score (KSS). RESULTS The mean patient age was 71.1 years, and the average follow-up period was 37 months (range, 12-138 months). Union was achieved in 47 patients (96%). The average final mLDFA was 90.5° in group P and 88.3° in group N. The average final knee range of motion was 130° in group P and 107° in group N. The average final KSS was 73.8 in group P and 87.1 in group N. CONCLUSION Dual plating for distal femoral fractures yielded an excellent union rate and limb alignment with a low complication rate.

Abstract
INTRODUCTION A residual fracture gap after intramedullary nailing is a known risk factor for delayed union and non-union. This study aimed to report the outcomes of a forward-striking technique to reduce fracture gaps during long cephalomedullary nailing in subtrochanteric femoral fractures (SFFs). METHODS A retrospective cohort study was conducted on patients with SFFs treated in a single institution between February 2013 and October 2018. A total of 58 patients treated via long cephalomedullary nailing with a forward-striking technique were included. The width of the fracture gap, location of the cephalic screw, tip-apex distance (TAD), and time to bone union were evaluated using intraoperative and postoperative radiographs. Complication rates, including fixation failure, non-union, implant breakage, and infection, were assessed. The mean follow-up duration was 4 (range, 2‒8) years. RESULTS Of the 58 patients (mean age, 67.9 years), 38 (65.5%) were female. Thirty-two cases (55.2%) were classified as atypical femoral fractures. The mean fracture gap reduced from 5.1 mm to 1.6 mm by forward striking (P<0.001). The reduced fracture gap was significantly greater in atypical SFFs (mean, 4.9 mm vs. 1.7 mm; P<0.001). The lag screw was located in the center-center or center-inferior zones of the femoral head in 54 patients (93.1%). The mean TAD was 14.2 mm and was under 25 mm in 55 patients (94.8%). Bone union was achieved in all cases without reoperation at a mean of 5.4 months. One incident of lag screw breakage was noted at 5 months, but bone union was achieved at 7 months. CONCLUSIONS The forward-striking technique with a long cephalomedullary nail demonstrated a 100% bone union rate in a consecutive series of 58 SFFs. This technique is effective in reducing the fracture gap as well as placing the cephalic screw into the optimal position. The forward-striking technique was particularly effective in reducing atypical SFFs with a transverse or short oblique configuration.

Abstract
PURPOSES Femoral implant related fractures (IRF) are a growing pathology in an increasingly elderly and frail population. A series of IRF after cephalomedullary nail (CMN) fixation of a femoral fracture is analyzed and an algorithm described to guide the management of such fractures. METHODS All eligible patients operated on for IRF fixation after CMN were reviewed regarding their demographics, comorbidities, injury pattern, and treatment. Primary outcomes were mortality and local complications. Secondary outcomes were time to consolidation, time to weight-bearing initiation, length of hospitalization, and discharge destination. RESULTS The incidence of IRF requiring fixation was 1.3% after 3401 CMN implantation procedures. Elderly women with comorbidities and plate fixation predominated. One-year mortality was 18.6%, being higher for patients presenting with infection and those unable to walk at the end of follow-up. Local complications occurred in 25.6%. Median time to weight-bearing was 9.1 weeks, but longer for patients with plate fixation or complications. Patients presenting with an infection and those discharged to nursing facilities had more comorbidity. CONCLUSIONS Following an algorithm presented here, patients were treated either with nail exchange or lateral locking plate fixation, permitting straightforward evaluations and acceptable results in a very high-risk population.

Abstract
BACKGROUND AND AIM Number of hip prosthesis implants in arthritis, number of patients treated with bisphosphonates to prevent fragility fractures and, together, number of atypical femoral fracture's cases are increasing. CASE SERIES This article describes two cases of hip arthritis, treated with hip replacement, in patients using bisphosphonates for a long time; in both cases an incomplete atypical femoral fracture was misdiagnosed before the surgery. Authors describe the importance to carry out a complete osteometabolic and radiographic pre-operative examination of patients in treatment with bisphosphonates going to hip replacement, to check the possible presence of incomplete atypical femoral fracture and to optimize surgical and pharmacological treatment. CONCLUSIONS In hip prosthesis surgery, prior diagnosis of incomplete atypical femoral fractures can indicate the choice of a different kind of prosthesis stem to optimize surgical results. This can also positively impact to rehabilitation in term of duration and daily activities recovery.

Abstract
➢ The prevalence of interprosthetic femur fractures (IFFs) is rising with the aging population and increased prevalence of total joint arthroplasty. ➢ IFFs have high rates of complications and high associated morbidity and mortality. ➢ The main treatment methods available for IFFs include plate fixation, intramedullary nailing, combined plate fixation and intramedullary nailing, and revision arthroplasty including partial and total femur replacement. ➢ There have been several proposed classification systems and at least 1 proposed treatment algorithm for IFFs; however, there is no consensus. ➢ Whichever treatment option is chosen, goals of surgery should include preservation of blood supply, restoration of length, alignment, rotation, and sufficient stabilization to allow for early mobilization.

Abstract
Although the American Society for Bone and Mineral Research definition of atypical femoral fracture excludes periprosthetic fractures, fractures around the prosthesis with clinical features of atypical femoral fractures have been reported in the literature. All fractures reported thus far have been distal to the prosthetic segment; however, we encountered a case of a stress fracture in the middle of the femoral component segment. An 86-year-old woman with a history of bisphosphonate osteoporosis treatment and revisional total hip arthroplasty visited our outpatient clinic complaining of pain in the left thigh and groin. We diagnosed an incomplete atypical femoral fracture around the hip prosthesis; medical treatment was implemented. Two months later, the patient visited the emergency department with a complete subtrochanteric fracture with stem breakage. Without revision of the broken stem, two plates were applied after reduction. In this case, we recognized the possibility of a stress fracture but overlooked the possibility of stem breakage in an atypical femoral fracture. Even if it is not evident on the radiograph before complete fracture, clinicians should be alert to the signs of stress fracture in the middle of the femoral component segment, as they may be clues to atypical periprosthetic femoral fracture with stem failure. Isolated medical treatment plans are not recommended for incomplete subtrochanteric atypical periprosthetic femoral fracture. Instead, concomitant prophylactic plate fixation is recommended.

Abstract
CASE Fractures of the femoral head are infrequent injuries with potentially devastating complications. Pipkin type II fractures often require surgical fixation. It involves intraarticular approaches that may increase the inherent morbidity of these fractures. Hip arthroscopy minimizes surgical aggression and allows for direct control of fracture reduction. We present a case report of an arthroscopic-assisted percutaneous fixation of a Pipkin-II femoral head fracture. A hip arthroscopy without traction and percutaneous screw fixation was conducted under arthroscopic and fluoroscopic guidance. CONCLUSION Arthroscopic-assisted percutaneous fixation is a useful technique for optimal femoral head fracture treatment and may also minimize surgical morbidity and optimize early recovery.

Abstract
RATIONALE A solution revision prosthesis has a multilayer microporous Porocoat coating, and the availability of multiple stem body sizes ensures that the prosthesis is adapted to each patient's anatomical structure so that there a firm attachment with the bone cortex in the middle of the femur. Therefore, the Solution prosthesis is one of the most commonly used and most effective prostheses in total hip arthroplasty worldwide. PATIENT CONCERNS We reported a case of a 54-year-old female patient with periprosthetic femoral fractures after hip arthroplasty. DIAGNOSIS The case was identified as type B2 prosthesis loosening according to the Vancouver classification. INTERVENTIONS We performed revision surgery on her using the Solution prosthesis. Seven months after the surgery, the patient developed a mid-femoral prosthesis fracture for no apparent reason. We performed a second revision surgery of the hip joint and allogeneic bone plate fixation. OUTCOMES The patient was satisfied with the treatment. LESSONS For patients with type B2 prosthesis loosening and prosthesis fracture, hip arthroplasty revision and an allogeneic bone plate could be used to ensure more stable support.
