Abstract
BACKGROUND Previous studies comparing reoperation risk between integrated dual lag screw (IDL) and single lag component (SL) cephalomedullary nails (CMNs) in the treatment of intertrochanteric femoral fractures have demonstrated mixed results. The purpose of this study was to assess the rates of reoperation for fixation failure and all-cause reoperation in a large, multi-institutional cohort of patients with an intertrochanteric fracture treated with an IDL or SL CMN. We hypothesized that there would be no difference between the groups with respect to either of the reoperation rates. METHODS Adults (≥18 years old) who sustained an intertrochanteric fracture (AO/OTA 31A1 to 31A3) treated with an IDL or SL CMN between January 2014 and May 2021 at 1 of 13 Level-I trauma centers were included. Patients with <3 months of follow-up or pathologic fractures were excluded. Rates of reoperation were compared with use of the chi-square test and multivariable regression, controlling for age, gender, injury mechanism, fracture pattern, and postoperative neck-shaft angle. RESULTS A total of 2,130 patients met the inclusion criteria. The median age was 78 years, and 62.5% of patients were female. The cohort consisted of 287 patients (13.5%) with an IDL CMN and 1,843 patients (86.5%) with an SL CMN. A total of 99 patients (4.6%) had a reoperation of any type, of whom 29 (1.4% of all patients) had a reoperation for fixation failure. Compared with patients with an SL CMN, those with an IDL CMN had higher rates (4.2% versus 0.9%; p < 0.001) and odds (odds ratio [OR], 4.95 [95% confidence interval (CI), 2.29 to 10.69]; p < 0.001) of reoperation for fixation failure as well as higher rates (7.3% versus 4.2%; p = 0.021) and odds (OR, 1.83 [95% CI, 1.10 to 3.06]; p = 0.021) of all-cause reoperation. CONCLUSIONS Intertrochanteric femoral fractures treated with an IDL CMN were associated with low but significantly higher rates and significantly higher odds of reoperation for fixation failure and all-cause reoperation compared with those treated with an SL CMN. We suggest caution to surgeons in the use of IDL CMNs for high-risk patients and recommend using SL CMNs for most patients with intertrochanteric femoral fractures.

Abstract
BACKGROUND AO/OTA 31A3 fractures (A3 fractures) have risk for postoperative complications with major impact on morbidity and mortality. For older patients, limited information is available for factors associated with postoperative complications. We aimed to assess factors associated with postoperative complications after surgery using cephalomedullary nails. METHODS A retrospective cohort study was conducted using the information on patients aged ≥65 years who underwent surgery using cephalomedullary nails for trochanteric fractures due to low-energy trauma in three hospitals. Postoperative complications were diagnosed when patients were identified as nonunion, cutout of lag screw, or nail breakage. First, we compared differences including age, sex, body mass index, American Society of Anesthesiologists physical status classification system, preoperative waking ability, fracture type, nail length, neck shaft angle, reduction method, reduction quality and tip apex distance between patients with and without postoperative complications. Second, multivariable logistic regression analysis was employed to assess factors associated with postoperative complications resulting from A3 fractures. RESULTS Among 120 patients with A3 fractures, postoperative complications were identified in 12 patients (10.0%). Postoperative complications were significantly more likely to develop among patients with poor reduction quality (adjusted odds ratio [95% confidence interval], 35.0 [4.43-275.9]) and a tip-apex distance ≥25 mm (16.4 [1.92-140.3]). CONCLUSIONS These findings suggest that surgeons should aim to perform appropriate postoperative reduction and to prevent postoperative complications when using a cephalomedullary nail for A3 fractures among older patients.

Abstract
Cephalomedullary nailing for unstable proximal femoral fractures is widely utilized, especially for geriatric osteoporotic fractures. There are two starting points for entry, namely trochanteric tip entry and pyriformis fossa entry, both have advantages and disadvantages, the tip of the greater trochanter seems that it is not the ideal starting point for trochanteric entry nails, the study presents the foothill entry point as a reproducible, technically feasible entry point to overcome the shortcoming of both standard starting points, and it could be easy executed with clear intraoperative fluoroscopic landmarks and lead to appropriate nail position without intraoperative complications.

Abstract
INTRODUCTION Despite the recent increase in the use of cephalomedullary nails for trochanteric hip fractures, factors that may be associated with peri‑implant femoral fracture (PIFF) after cephalomedullary nailing for trochanteric fractures remain unknown. We investigated the factors associated with PIFF after cephalomedullary nailing of trochanteric hip fractures in older patients. METHODS A nested case-control study was conducted using a database of patients aged ≥65 years who underwent surgery with cephalomedullary nails for trochanteric fractures caused by low-energy trauma during 2005-2021. The cases were defined as patients who developed PIFF after surgery, while controls were patients who did not develop PIFF and who were followed up for ≥3 years after surgery. Four controls were randomly matched to each case for sex and age. First, potential factors associated with PIFF were compared between cases and controls. Second, multivariable conditional logistic regression analysis was employed to assess factors possibly associated with PIFF, controlling for potential confounding factors. RESULTS Of 1531 patients who underwent surgery with cephalomedullary nails because of trochanteric fractures, we assessed 34 cases and 136 controls (N = 170; mean age 85.7 ± 7 years; and females, 94 %). PIFF was significantly associated with patients having undergone total knee arthroplasty (adjusted odds ratios [95 % confidence intervals], 4.41 [1.16-16.8]) and those with AO/OTA classification 31A3 fracture (A3 fracture) (2.3 [1.12-4.76]), after adjusting for potential confounding factors. CONCLUSIONS Our results showed that PIFF was more likely to develop among older patients with a clinical history of total knee arthroplasty and A3 fracture. These findings suggest that such patients may require careful follow-up with rigorous assessments after cephalomedullary nailing for trochanteric fractures.

Abstract
INTRODUCTION The overall frequency of proximal femoral fractures means that we are repeatedly confronted with failed healing and implant failure, despite a relatively low nonunion rate especially in intertrochanteric fractures (< 5%). The aim of this paper is to present our approach to treating these nonunions of the proximal femur and discuss the treatment results. MATERIAL AND METHODS Between 2009 and 2023, patients with nonunion of the proximal femur were retrospectively identified and analyzed. Age, gender, time to revision, the Weber-Cech classification of pseudarthrosis and radiographic imaging before and after revision were analyzed. RESULTS A total of 66 patients were analyzed. The mean age was 58 years (range 25-88 years). The overall healing rate was 88% with a mean consolidation time of 8 months (range 2-29 months). The main osteosynthesis procedures were plate osteosynthesis (n = 45, of which 44 were blade plates), and nail replacement (n = 12). Other procedures included augmentative plate osteosyntheses (n = 4), isolated cancellous bone graft (n = 2), nail dynamization (n = 2), and the use of a dynamic hip screw (n = 1). DISCUSSION The analysis of our treatment data as well as the current literature, revealed a trend towards intramedullary revision procedures. Implants that can be used to correct the CCD angle, such as the blade plate, remain a predictable option to achieve correction, especially in nonunions with an increased degree of varus. Particularly in the subtrochanteric region, fractures can also be treated in a targeted manner by a combination of mechanical and biological methods with a reamed nail change to a larger caliber implant.

Abstract
This study aimed to compare the biomechanical performance of an intramedullary nail combined with a reconstruction plate and a single intramedullary nail in the treatment of unstable intertrochanteric femoral fractures with a fracture of the lateral femoral wall (LFW). A three-dimensional finite element (FE) femur model was established from computed tomography images of a healthy male volunteer. A major reverse obliquity fracture line, associated with a lesser trochanteric fragment defect and a free bone fragment of the LFW, was developed to create an AO/OTA type 31-A3.3 unstable intertrochanteric fracture mode. Two fixation styles were simulated: a long InterTAN nail (ITN) with or without a reconstruction plate (RP). A vertical load of 2100 N was applied to the femoral head to simulate normal walking. The construct stiffness, von Mises stress, and model displacement were assessed. The ITN with RP fixation (ITN/RP) provided higher axial stiffness (804 N/mm) than the ITN construct (621 N/mm). The construct stiffness of ITN/RP fixation was 29% higher than that of ITN fixation. The peak von Mises stress of the implants in the ITN/RP and ITN models was 994.46 MPa and 1235.24 MPa, respectively. The peak stress of the implants in the ITN/RP model decreased by 24% compared to that of the ITN model. The peak von Mises stress of the femur in the ITN/RP model was 269.06 MPa, which was lower than that of the ITN model (331.37 MPa). The peak stress of the femur in the ITN/RP model was 23% lower than that of the ITN model. The maximum displacements of the ITN/RP and ITN models were 12.12 mm and 13.53 mm, respectively. The maximum displacement of the ITN/RP model decreased by 12% compared with that of the ITN model. The study suggested that an additional plate fixation could increase the construct stiffness, reduce the stresses in the implant and femur, and decrease displacement after intramedullary nailing. Therefore, the intramedullary nail and reconstruction plate combination may provide biomechanical advantages over the single intramedullary nail in unstable intertrochanteric fractures with a fractured LFW.

Abstract
BACKGROUND Early assessment of the risk of nonunion in osteoporotic vertebral compression fracture (OVCF) is beneficial to early clinical decision making. However, a comprehensive understanding of the risk factors for OVCF nonunion is lacking. METHODS We conducted a case-control study to investigate risk factors for OVCF nonunion. Patients who underwent surgery for nonunited OVCFs between January 2011 and December 2021 were eligible for inclusion as cases. Patients with successful OVCF healing confirmed by MRI over the same period were identified as controls. Patient demographics, comorbidities, and fasting blood test data were extracted for analysis. RESULTS A total of 201 patients with nonunited OVCFs and 1044 controls were included to evaluate the risk factors for nonunited OVCFs. There were statistically significant differences in sex, age, number of patients with hypertension, number of patients on bed rest after OVCF and T-score of BMD between the two groups. Logistic regression showed that female patients had a higher risk of OVCF nonunion than male patients and that smoking, drinking, diabetes, and hypertension were risk factors for nonunion of OVCFs, while bed rest and spinal support were protective factors against nonunion of OVCFs. We also found that age, BMD, FBG, and β-CTX were positively correlated with nonunited OVCFs, and that HGB and 1,25-(OH)2VitD3 level were negatively correlated with nonunited OVCFs. CONCLUSION Smoking, drinking, diabetes and hypertension were risk factors for nonunion of OVCFs, while bed rest and spinal support were protective factors against nonunion of OVCFs. Age, BMD, FBG and β-CTX were positively correlated with nonunited OVCFs, while HGB and 1,25-(OH)2VitD3 level were negatively correlated with nonunited OVCFs. Based on the results of our study, we suggest that bed rest or spinal support for at least 3 consecutive weeks is necessary to reduce the risk of OVCFs nonunion.

Abstract
INTRODUCTION Low platelet counts have clinically relevant effects on patient outcomes after hip fracture surgery; however, the relationship between abnormally high platelet counts and postoperative outcomes in this population is unknown. METHODS The ACS-NSQIP database was queried for patients who underwent hip fracture surgery between 2015 and 2019. Outcomes were compared between patients with normal platelet counts (150,000 to 450,000/μL) and thrombocytosis (>450,000/μL). RESULTS Eighty-six thousand three hundred eleven hip fracture patients were identified, of which 1067 (1.2%) had preoperative thrombocytosis. Compared with patients with normal platelet counts, patients with preoperative thrombocytosis had increased rates of 30-day mortality (6.4% vs 4.5%, P = 0.004; OR 1.15 [95% CI 0.88 to 1.50], P = 0.322) as well as increased rates and odds of readmission (11.4% vs 7.8%, P < 0.001; OR 1.35 [95% CI 1.10 to 1.65], P = 0.004) and venous thromboembolic events (3.2% vs 1.7%, P < 0.001; OR 1.88 [95% CI 1.31 to 2.71], P < 0.001). CONCLUSIONS Hip fracture patients with preoperative thrombocytosis had increased rates of early mortality as well as increased odds of venous thromboembolic events and readmission. A patient with thrombocytosis may benefit from close postoperative surveillance and careful follow-up. Future prospective studies are needed to verify causation and investigate how to mitigate adverse outcomes in hip fracture patients with preoperative thrombocytosis.

Abstract
PURPOSE Determine if any fracture characteristics or radiographic parameters were predictive of fixation failure [FF] within 1 year following cephalomedullary nailing for intertrochanteric fractures. METHODS A consecutive series of intertrochanteric hip fracture patients (AO/OTA 31A) treated with a cephalomedullary nail were reviewed. Pre-fixation (neck-shaft angle [NSA], distance from ischial tuberosities to greater and lesser trochanters, integrity of lesser trochanter, and fracture angulation) and post-fixation (post-fixation NSA, posteromedial cortex continuity, lag screw position, tip to apex distance [TAD], and post-fixation angulation and translation) radiographic parameters were measured by blinded independent reviewers. The FF and non-FF groups were statistically compared. Logistic regression was performed to determine radiographic parameter correlates of FF. RESULTS Of 1249 patients, 23 (1.8%) developed FF within 1 year. The FF patients were younger than their non-FF counterparts (77.2 years vs 81.0 years, p=0.048), however there were no other demographic differences. The FF cohort did not differ in frequency of TAD over 25 mm (4.3% vs 9.6%, p=0.624) and had decreased mean TAD (13.6mm vs 16.3mm, p=0.021) relative to the non-FF cohort. The FF cohort had a higher rate of a post-fixation coronal plane NSA more than 10° different from the contralateral side (delta NSA>10°, 34.8% vs 13.7%, p=0.011) with the majority fixed in relative varus. For every 1° increase in varus compared to the contralateral side the odds of FF increased 7% (OR=1.065, 95%CI[1.005-1.130], p=0.034) on univariate analysis. On univariate logistic regression, patients with an absolute post-fixation NSA of 10° or more of varus compared to contralateral were significantly more likely to have a FF (OR=3.139, 95%CI[1.067-8.332], p=0.026). CONCLUSION Despite an acceptable TAD, post-fixation NSA in relative varus as compared to the contralateral side was significantly associated with failure in intertrochanteric hip fractures fixed with a cephalomedullary nail. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
Background This study aimed to demonstrate the feasibility of lag screw exchange for painful lateral soft tissue impingement in patients initially treated with cephalomedullary nailing (CMN) for an intertrochanteric hip fracture. Methods Ten patients initially treated with CMN for unstable intertrochanteric fractures presenting with persistent pain and radiographic evidence of lag screw lateral migration were treated with exchange of original screw with shorter lag screw buried in the lateral cortex to prevent impingement. Patients were evaluated for resolution of pain and achievement of pre-fracture ambulatory status at 6 months post-operatively. Results Average age was 71.5 years (range: 62-88). Average length of follow-up was 24.9 months. All patients were female, with an average Charlson Comorbidity Index of 1.0 (0-3) and average Body Mass Index of 22.2 (16.0-31.1). Five of ten patients (50.0%) were treated with a cortisone injection in the trochanteric bursa prior to screw exchange with temporary pain relief. Five (50.0%) patients presented with limited range of hip motion. Five (50.0%) had history of prior or current bisphosphonate use. Average lag screw prominence was noted to be 12.2mm (7.9-17.6mm) on radiographic evaluation. Screw exchange was performed at an average of 18.6 months (5.4-44.9 months) following the index procedure. Average operating time of the screw exchange procedure was 45.3 minutes (34-69 minutes) and blood loss was <50mL in all cases. Replacement lag screws were an average of 16.0mm (10-25mm) shorter than the initial screw. All patients achieved complete or significant resolution of lateral thigh pain, and nine (90%) returned to pre-fracture ambulatory status by eight weeks after screw exchange. All patients remained pain free at six months after screw exchange. Conclusion Lag screw exchange is a efficacious method to address the mechanical irritation of laterally protruding lag screws following IT hip fracture, while also prophylaxing against subsequent femoral neck fractures. Level of Evidence: IV.

Lai CY, Liu CH, Lai PJ, Hsu YH, Chou YC, Yu YH. Perioperative peri-implant fracture after osteosynthesis for geriatric femoral pertrochanteric fracture with the linear compression integrated screw intramedullary nail system (INTERTAN™): a retrospective study. J Orthop Surg Res 2023; 18:932. [PMID: 38057901 DOI: 10.1186/s13018-023-04441-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 12/03/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Osteosynthesis for geriatric femoral pertrochanteric fractures using the linear compression integrated screw intramedullary nail system (INTERTAN™) has become popular. Nonetheless, cases of perioperative peri-implant fractures have been reported following this surgical technique. The factors responsible for this complication remain unclear. Therefore, we investigated perioperative peri-implant fracture risk factors and incidence, as well as overall outcomes, using the INTERTAN™ system for geriatric femoral pertrochanteric fractures. METHODS We retrospectively reviewed 98 consecutive patients with geriatric femoral pertrochanteric fractures after INTERTAN™ fixation, with at least a 12-month follow-up period between May 2020 and April 2022 at a single medical institute. The patients' demographic characteristics, fracture pattern, quality of reduction, quality of fixation, nail length, morphology of the femur, and perioperative complications were recorded and analyzed. RESULTS Among the 98 patients, 92 achieved union during follow-up. Twelve perioperative peri-implant fractures (12.2%) were recorded, all of which occurred during or within 1 month of osteosynthesis. Except for one patient who underwent re-osteosynthesis, the others underwent nonoperative treatment, and all achieved union. Multiple regression analysis revealed morphology of the femur with low-lesser trochanter width (odds ratio (OR) 0.532, 95% confidence interval (CI) 0.33-0.86, p = 0.01) to be the only factor contributing to perioperative peri-implant fractures. When the Youden index was used, the optimal cut-off value was 20.2 mm of low-lesser trochanter width. Low-lesser trochanter width < 20.2 mm was found to be a potential factor causing perioperative peri-implant fractures (OR 17.81, 95% CI 1.67-19.76, p = 0.017). CONCLUSIONS Morphology of the femur with a low-lesser trochanter width smaller than 20.2 mm was found to be the only potential contributor to perioperative peri-implant fractures when using INTERTAN™ for geriatric femoral pertrochanteric fractures. Care should be taken during osteosynthesis, focusing not only on the fracture site but also on the femoral cortex around the implant. Although perioperative peri-implant fractures were observed within one month following osteosynthesis, the majority of these cases were effectively treated without surgical intervention.

Abstract
INTRODUCTION The aim of this study was to describe the clinical and radiological results of reverse obliquity intertrochanteric fractures treated with dynamic distal locked intramedullary hip nails. MATERIALS AND METHODS Patients with a reverse obliquity intertrochanteric fracture (AO/OTA type 31 A3.1 or A3.3) underwent surgical treatment with a dynamic distal locked intramedullary hip nail between August 2017 and September 2020. Fracture type, reduction quality, change in the position of the distal bone fragment, bone union, complications, and walking ability were evaluated. RESULTS Ten patients with reverse obliquity intertrochanteric fractures (seven females and three males) underwent dynamic distal locked intramedullary hip nailing. The mean age was 72.0 ± 18.9 years. Two patients were classi fied as having A3.1 fractures; eight patients were classified as having A3.3 fractures. Anatomical reduction was achieved in six patients, medial displacement remained in three patients, and lateral displacement remained in one patient postoperatively. In 9 out of 10 patients, the center of the proximal end of the distal bone fragment had moved laterally between the time immediately after surgery and the time of the final evaluation. Bone union was obtained uneventfully without any additional treatments in all patients. There were no complications such as infection or implant failure. Walking ability decreased in four patients. CONCLUSION In all patients, bone union was achieved due to good contact of the medial cortices or the migration of the distal bone fragment into the proximal bone fragment. This procedure can be an option for treating reverse obliquity intertrochanteric fractures.

Abstract
A proper and reliable fracture fixation is important for fracture healing. The proximal femoral intramedullary nail (IN), such as proximal femoral nail anti-rotation (PFNA) or Gamma nail, is widely used for intertrochanteric fracture fixation. However, it still suffers considerable stress concentrations, especially at the junction between the nail and the blade or lag screw. In this study, we propose a novel intramedullary nail design to enhance the intramedullary nail integrity by introducing a bolt screw to form a stable triangular structure composed of the nail, the lag screw, and the bolt screw (PFTN, Proximal femoral triangle nail). Systematic finite element numerical simulations were carried out to compare the biomechanical performances of PFTN and PFNA under both static and dynamic loads during the postures of ascending and descending stairs. The simulation results highlight the advantages of the proposed PFTN design with lower stresses, less stress concentration, and higher structure stability.

Abstract
BACKGROUND Surgical treatment of pertrochanteric fractures is one of the most performed surgeries in orthogeriatrics. Proximal femoral nailing, the most performed procedure, is often used as a training surgery for young residents. The objective of this study was to evaluate the relevance of the resident's training level to complication rates. MATERIAL AND METHODS This study was a retrospective cohort study. Surgeons were divided into four groups according to their training level. Complications included infection, cut-out, and revision surgery. The study was performed at a level 1 trauma center. All patients who were treated with proximal femoral nailing surgery with a radiological follow-up of at least 3 months were included. RESULTS Of the 955 patients extracted, a total of 564 patients met the inclusion criteria. Second-year residents had significantly higher cut-out rates (p = 0.012). Further analysis indicated a correlation between level of training and surgery duration (p < 0.001) as well as a correlation between surgery duration and infection rate (p < 0.001). The overall complication rate was 11.2%. Analyzing overall complications, no significant difference was found when comparing surgeon groups (p = 0.3). No statistically significant difference was found concerning infection (p = 0.6), cut-out (p = 0.7), and revision surgery (p = 0.3) either. CONCLUSION Complication rates after proximal femoral nailing are not higher in patients who are treated by residents. Therefore, proximal femoral nailing is an excellent procedure for general orthopedic training. However, we must keep in mind that accurate positioning of the femoral neck screw is essential to keep cut-out rates as low as possible. LEVEL OF EVIDENCE III

Abstract
OBJECTIVES The primary objective of the current study is to assess which is better for obtaining the proper femoral rotation during IMN of femoral fractures, the radiological or clinical method. The secondary objectives were to document malrotation's incidence and its effect on the hip and knee functional outcomes. METHODS Thirty-three patients with unilateral femoral shaft fractures were treated using intramedullary nails (IMN) on a usual radiolucent operative table. Intraoperative rotation adjustment was performed using a radiological method (relying on the contralateral lesser trochanter profile) in 16 patients (group A), while in 17 patients, a clinical method was used (group B). Postoperative assessment of malrotation was performed using a CT scan, and 15 degrees was the cutoff value where below is an acceptable rotation (group I) and above is true malrotation (group II). Functional assessment was performed using the Harris hip score (HHS), the Tegner Lysholm Knee Scoring Scale (TLKSS), and the Neer score. RESULTS The patients' mean age was 30.7 ± 9.3 years; 81.8% were males, and the left side was injured in 63.6% of patients. After a mean follow up of 18.2 ± 6.9 months, all fractures were united, and the overall mean amount of rotational difference between the fractured and the contralateral side was 14.7° ± 6.0 (3-29.4), 84.8% were in external rotation. No difference in the mean rotational deformity in group A compared to group B. Measurements were 13.9 ± 6.7 and 15.7 ± 5.5, respectively (p = 0.47). Seventeen (51.5%) patients in group I with a mean deformity of 9.8 ± 3.4 (3-14.7), while group II consisted of 16 (48.5%) patients with a mean deformity of 19.6 ± 3.7 (15.3-29.4). There was no difference in the functional scores between group I and group II; HHS was 89.4 ± 7.4 versus 87.7 ± 8.9 (p = 0.54), TLKSS was 84.6 ± 9.6 versus 80.4 ± 13.9 (p = 0.32), and Neer score was 87.9 ± 9.5 versus 83 ± 12.5 (p = 0.21) for group I and group II, respectively. CONCLUSION There was no difference in malrotation incidence after unilateral femoral fractures IMN with either an intraoperative clinical or radiological method for rotational adjustment; furthermore, malrotation did not affect the functional outcomes.

Abstract
OBJECTIVES To describe a reproducible technique for reduction assessment and percutaneous reduction of unstable intertrochanteric fractures treated with a cephalomedullary nail on a traction table. DESIGN Retrospective cohort study. SETTING Level-1 trauma center. PATIENTS Two-hundred 20 consecutive patients with intertrochanteric fractures. INTERVENTION Initial closed reduction performed on a traction table. Accessory incisions were used to facilitate a reduction in 77 patients (35%). All fractures were stabilized with a cephalomedullary nail. MAIN OUTCOME MEASUREMENTS Radiographic outcome including union, cutout, and fracture collapse (FC). Surgical outcomes including infection and hematoma were also reported. RESULTS Mechanical complications (nonunion, cutout, and varus collapse) occurred in 8.8% of patients at 1 year. Eleven of 13 patients who developed these complications had either suboptimal implant placement (tip-to-apex distance >25 mm) or a varus reduction. There was no difference in the incidence of reoperation, nonunion, lag screw cutout, or posttraumatic arthritis based on the use of an accessory incision for fracture reduction. There was a significant increase in FC in patients who received an accessory incision (6.8 mm vs. 5.4 mm, P = 0.04). One patient (1%) developed a hematoma in the accessory incision cohort, and 1 patient (0.7%) who did not have an accessory incision developed a postoperative infection. CONCLUSIONS The current study suggests utilization of accessory incisions assist in reduction is safe and is associated with a low rate of complications. The surgeon should prioritize fracture reduction and optimal implant placement and not hesitate to use an accessory incision to assist with fracture reduction. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
BACKGROUND cephalomedullary devices are popular treatment for femoral intertrochanteric or subtrochanteric fractures. Various complications include post-surgical lateral thigh pain and cut-out. To prevent those complications, a new concept cephalomedullary device system was designed (Chimaera, Orthofix®). This study aimed to evaluate the clinical and radiological outcomes in patients with femoral intertrochanteric or subtrochanteric fractures treated with the proximal femoral cephalomedullary device system. METHODS A prospective cohort study involved consecutive patients with Arbeitsgemeinschaft für Osteosynthesefragen/ Orthopaedic Trauma Association type 31-A1, 2, 3 fractures treated with the Chimaera short cephalomedullary device system from October 2016 to September 2017 at our level 1 trauma center. The Parker and Palmer mobility score and Jensen social function scores and post-surgical lateral thigh pain were assessed at 3 months post-operatively and compared to before surgery. Radiologic assessment consisted of controlling the position of the cephalic screw by using the tip-apex distance (TAD) and Cleveland zone as well as union and cut-out rates. RESULTS We included 99 patients (79 women; 100 hips; one bilateral fracture 3 months after a first trochanteric fracture) with a mean follow-up of 2 years. The Parker and Palmer mobility score decreased by 22% at 3 months post-operatively as compared with the pre-fracture score (42/99 patients showed a return to their pre-injury level). The Jensen social function score increased by 16.5% at 3 months post-operatively as compared with the pre-fracture score (68/99 patients showed a return to their pre-injury level). No major intra-operative complication was recorded. Nine TAD scores were > 25 mm. The mean TAD was 16.5 mm (range 5-36), and the lag screw position was well positioned in most (95%) hips according to Cleveland zones. Three patients required revision surgery (one for cut-out of the lag screw, one for hip osteoarthritis and one for gluteus medius insufficiency). All patients but the one with the cut-out showed fracture union. CONCLUSION The Chimaera short cephalomedullary device exhibited good mid-term functional and radiological outcomes.

Abstract
BACKGROUND Extracapsular femoral neck fractures (eFNF) are the third most common type of fracture in traumatology. Intramedullary nailing (IMN) is one of the most frequently used ortho-pedic treatments for eFNF. Blood loss is one of the main complications of this treatment. This study aimed to identify and evaluate the perioperative risk factors that lead to blood transfusion in frail patients with eFNF who undergo IMN. METHODS From July 2020 to December 2020, 170 eFNF-affected patients who were treated with IMN were enrolled and divided into two groups according to blood transfusion: NBT (71 patients who did not need a blood transfusion), and BT (72 patients who needed blood transfusion). Gender, age, BMI, pre-operative hemoglobin levels, in-ternational normalized ratio (INR) level, number of blood units transfused, length of hospital stay, surgery duration, type of anesthesia, pre-operative ASA score, Charlson Comorbidity Index, and mortality rate were assessed. RESULTS Cohorts differed only for pre-operatively Hb and surgery time (p < 0.05). CONCLUSION Patients who have a lower preoperative Hb level and longer surgery time have a high blood-transfusion risk and should be closely followed peri-operatively.

Conversion arthroplasty after failed extracapsular hip fracture fixation is associated with high complication rates. JOURNAL OF SURGERY AND MEDICINE 2023.

Abstract
Background/Aim: There is no standard treatment of choice that addresses all extracapsular fractures, which account for approximately half of the elderly hip fractures. Arthroplasty is mostly favored secondary to unsuccessful fixation or unstable primary fractures. However, conversion arthroplasty complication rates are high in the literature. This study compares arthroplasty performed after unsuccessful fixation and primary arthroplasty for unstable extracapsular hip fractures.
Methods: In this retrospective study, we compared the first-year results of the groups that underwent conversion arthroplasty (cHA) and the primary arthroplasties (pHA) for extracapsular hip fractures. In the cHA group, patients were indicated for operation if there was a failure of fixation after extracapsular hip fractures (n=44). In the pHA group, patients were for unstable extracapsular hip fractures (n=44). In the cHA group, failure of fixation causes were cut-out of lag screws (54.5%), cut-through of lag screws (9.1%), non-union of fractures (27.3%), and osteonecrosis of femoral heads (9.1%). While total hip replacement was applied to all patients in the cHA group, total hip replacement was applied to ten patients in the pHA group and hemiarthroplasty to 34 patients. In comparing groups, duration of operation, amount of bleeding, intraoperative complications, post-operative complications, mobilization capacities, functional status, and mortality rates were used.
Results: There were 44 patients in both groups. The surgical time (134.3 [34.5)] vs. 66 [16], [P<0.001]), the amount of bleeding (1000 ml [400] vs. 300ml [200], [P<0.001]), the need for red blood cell transfusion in the operations (80% vs. 32%, [P<0.001]), and the frequency of intraoperative femur fracture (30% vs. 0%, [P<0.001]) were larger or longer in the cHA group compared to pHA group (P<0.001). While 14 complications requiring surgical intervention were observed in 12 of 44 patients in the CHA group in the post-operative 1st year, four complications were observed in four of 44 patients in the pHA group. There was no difference in mortality rates (3 vs. 3, [P =1]), mobilization capacities (5.9 [2.1] vs. 5.7 [2.0], [P=0.597]), and functional status (12.5 [3.3] vs. 13.0 [2.7], [P=0.434]) between the groups.
Conclusion: Arthroplasty performed as conversion surgery after unsuccessful fixation has a higher risk of intraoperative and post-operative complications than primary arthroplasty performed after extracapsular hip fractures. We believe the cases prone to implant failure, non-union, or restricted mobilization because of the patient and fracture-type reasons should be treated with primary arthroplasty.

Evaluation of femoral head bone quality by Hounsfield units: A predictor of implant failure for intertrochanteric fractures after intramedullary nail fixation. Front Surg 2023; 9:816742. [PMID: 36684160 PMCID: PMC9852507 DOI: 10.3389/fsurg.2022.816742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Accepted: 10/21/2022] [Indexed: 01/09/2023] Open
Abstract
Purpose The aim of present study is to evaluate the femoral head bone quality by Hounsfield units and its relationship to the occurrence of implant failure for intertrochanteric fractures after intramedullary nail fixation. Methods This retrospective study assessed 160 intertrochanteric fractures treated with intramedullary fixation. Patients with and without implant failure were divided into failure and control groups, respectively. The demographic information, femoral head Hounsfield unit (HU) value, the reduction quality, status of posteromedial support and position of the screw/blade were collected and compared. The logistic regression analyses were performed to evaluate risk factors of implant failure in intertrochanteric fractures after intramedullary nail fixation. Results Of the patients, 15 (9.38%) suffered from implant failure after intramedullary fixation. The mean HU value of femoral head was much lower in the failure group than the control group (133.25 ± 34.10 vs. 166.12 ± 42.68, p = 0.004). And the univariate analyses showed that A3 fracture and poor reduction quality were associated with implant failure (p < 0.05). After adjustment for confounding variables, the multivariable logistic regression analyzes showed that femoral head HU value (odds ratio [OR], 0.972; 95% CI, 0.952-0.993; p = 0.008) and poor reduction quality (OR, 7.614; 95% CI, 1.390-41.717; p = 0.019) were independent influencing factors for implant failure. Conclusion The femoral head HU value was significantly correlated with the incidence of implant failure and can be used as an independent factor to predict implant failure for intertrochanteric fractures after intramedullary fixation.

Abstract
OBJECTIVES The aim of the present study was to introduce a novel three-dimensional computed tomography (3DCT)-based three-column classification (named "MLP classification system") of intertrochanteric fractures and evaluate its reproducibility and reliability. METHODS From September 2020 to September 2022, a total of 258 consecutive patients (60 male, 198 female;mean age 81.3 years) with intertrochanteric fractures were included in this study. The fracture in each case was assessed using a novel three-dimensional computed tomography-based three-column classification. Two examiners tested the intra and inter-observer reliability of this new classification system using kappa variance. RESULTS The intertrochanteric region was divided into the medial column, lateral column, and posterior column. Intertrochanteric fractures were documented as M0/1/2L0/1/2/3P0/1/2/3. All fractures were classifiable into the new classification system. The intra-observer kappa values were 0.91 and 0.89, while the inter-observer kappa value was 0.82, both indicating almost perfect reliability. CONCLUSION This novel 3DCT-based MLP classification system for intertrochanteric fractures is comprehensive, and reproducible with good agreement. It is based on proximal femur biomechanic characteristics and traumatic mechanism, contributing to formulating more reasonable treatment protocols involving various late-model internal fixation devices.

Mechanical Complications After Intramedullary Fixation of Extracapsular Hip Fractures. J Am Acad Orthop Surg 2022; 30:e1550-e1562.

Abstract
Extracapsular hip fractures occur frequently in the elderly as a result of low-energy trauma. Achieving stable fixation in osteoporotic bone to allow early weight bearing is a key objective in the treatment of these injuries. Many of the intraoperative decisions facing surgeons are directed by first determining fracture stability. Unstable fracture patterns should be fixated with intramedullary nails, aiming to control motion around the implant and at the fracture site. Torsion control devices provide additional stability and control, although their exact indications are not precisely defined. Complications that arise as a result of the early loading can be avoided with a good surgical reduction, meticulous technique, and proper implant selection. Mechanical complications include cutout, inordinate proximal femoral shortening, delayed union, early implant fracture, nail toggle, and cut through/medial migration.

Abstract
Femoral neck fracture in the absence of trauma is a rare, but known complication after hardware removal. This complication may be due to the boney defect created by the hardware removal itself, or the increase in femoral neck strain that occurs after removal of the hardware. Previous biomechanical studies have suggested that filling the defect with calcium phosphate cement after removal of hardware may prevent the development of a femoral neck fracture. However, there are no reports on the use of calcium phosphate cement after removal of hardware in the clinical setting. The purpose of this case discussion is to present the first reported case, to our knowledge, of the use of calcium phosphate cement augmentation of the boney defect after lag screw removal, and the subsequent failure resulting in atraumatic femoral neck fracture.

Conversion total hip arthroplasty following extracapsular hip fracture fixation with a cephalomedullary device: a comprehensive review. Arch Orthop Trauma Surg 2022; 143:3525-3533.

Abstract
With the annual incidence of hip fractures and hip fracture fixation rising, the need for conversion total hip arthroplasty has also risen. About half of the 280,000 hip fractures that occur annually in the United States are extracapsular. Commonly extracapsular hip fractures are treated with either cephalomedullary nails (CMNs) or sliding hip screws (SHS). More recently, there has been a shift toward increased CMN use due to increased training with this fixation method as well as perioperative and biomechanical benefits. Given this shift, orthopedic surgeons need to understand the factors that lead to CMN failure. Failed CMN treatment leaves both patients and surgeons with few management options including revision fixation with or without osteotomy, conversion total hip arthroplasty, and conversion hemiarthroplasty. Surgeons must consider the patient and injury characteristics before deciding the best treatment plan. Conversion total hip arthroplasty is indicated in younger patients without femoral head and/or acetabular articular injury, degenerative joint disease, or avascular necrosis. Conversion total arthroplasty is a technically demanding and resource-intensive surgery associated with lower success rates and outcomes than primary total hip arthroplasty. Orthopedic surgeons should have thorough understanding of preoperative workup needed prior to surgery, implant selection associated with best outcomes, most common surgical approaches used, intraoperative considerations, and complications associated with conversion total hip arthroplasty. A comprehensive understanding of these concepts gives patients the best chance of having a successful outcome.

Abstract
INTRODUCTION Despite advancements in surgical techniques complications like implant failure is very common after the fixation of intertrochanteric fractures. Classifying these complex fractures based on plain radiographs underestimates the complexity of these fractures which in turn leads to complications. We propose a comprehensive classification of the intertrochanteric fractures based on 3D Non Contrast Computed Tomography (3D NCCT) scan. MATERIAL AND METHODS A total of 102 patients (51 males and 51 females) with intertrochanteric fractures were included in this study conducted over a time period of 22 months in a Tertiary care center in North India. NCCT proximal femur of the intertrochanteric fracture patients was done to formulate a new CT classification system and classify all fractures. Intra and inter-observer reliability was tested using kappa variance. RESULTS New classification system was proposed which included 3 main and a total of 6 groups. All the fractures were classifiable into the new system. Kappa variance of the study showed a good intra and interobserver reliability (0.95 and 0.90) proving clinical agreement of the classification. CONCLUSION This new 3D-CT based classification has the advantages of being easy, comprehensible with high intra and inter-observer reliability. This 3DCT based classification can prove to be useful to detect occult intertrochanteric fractures undetectable in plain radiographs as well as choosing the optimum treatment plan.

Abstract
PURPOSE Postoperative over-telescoping (OT) with lag screws is often observed in reverse oblique intertrochanteric fractures. This study aimed to clarify the risk factors of OT in patients with reverse oblique intertrochanteric fractures. METHODS Electronic medical records of patients diagnosed with reverse oblique intertrochanteric fractures using plain radiography who underwent operative fixation with an intramedullary nail between August 2013 and December 2019 were reviewed. Patients were classified into two groups according to the Futamura classification: lateral wall pattern (LW) and reverse oblique pattern (RO). The incidence of OT in the LW and RO groups was compared. Also, we compared the incidence of OT for each reduction type in the LW group. RESULTS Twenty patients had LW, and nine had RO. OT was observed in eight fractures (42.1%) in the LW group but not in the RO group. The incidence of OT was significantly higher in the LW group than in the RO group (P = 0.0261). Among the 19 fractures with LW, OT was observed in 7 of 10 and 1 of 9 fractures with postoperative reduction in the intramedullary and extramedullary or anatomical types, respectively. In the LW group, the incidence of OT was significantly higher in fractures with postoperative reduction in the intramedullary type than in those of the extramedullary or anatomical type (P = 0.0198). CONCLUSION Our study showed that the incidence of OT was significantly higher in LW than in RO and that postoperative reduction in the intramedullary type in LW was a risk factor for OT.

Abstract
BACKGROUND Intertrochanteric (IT) fracture is one of the most common fractures seen in an orthopaedic practice. Proximal femoral nailing (PFN) is a common modality of fixing IT femur fracture. We retrospectively studied whether a PFN with two proximal lag screws can be done without distal interlocking screws in the 31-A1 and 31-A2 fracture patterns according to the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) guidelines for IT femur fractures.
AIM To compare the outcomes of IT fractures (AO/OTA 31-A1 and 31-A2) treated by PFN with and without distal interlocking screws.
METHODS We carried out a retrospective study of 140 patients in a tertiary care centre who had AO/OTA type 31-A1 and 31-A2 IT fractures. We divided the patients into two groups, in which one of the groups received distal interlocking screws (group 1) and the other group did not (group 2). The subjects were followed up for a mean period of 14 mo and assessed for radiological union time, fracture site collapse, mechanical stability of implant, and complications associated with the PFN with distal interlocking and without distal interlocking. Then, the results were compared.
RESULTS PFN without distal interlocking screws has several advantages and gives better results over PFN with distal interlocking screws in the AO/OTA 31-A2 fracture pattern. However, similar results were observed in both groups with the fracture pattern AO/OTA 31-A1. In patients with fracture pattern AO/OTA 31-A2 treated by PFN without distal interlocking screws, there were minimal proximal lock-related complications and no risk of distal interlock-related complications. The operative time, IITV radiation time and time to radiological union were reduced. These patients also had better rotational alignment of the proximal femur, and the anatomy of the proximal femur was well maintained. It was also noted that in the cases where distal interlocking was performed, there was a gradual decrease in neck shaft angle, which led to varus collapse and failure of bone-implant construct in 21.40%.
CONCLUSION In fracture pattern AO/OTA 31-A2, PFN without distal interlocking had better results and less complications than PFN with distal interlocking.

Abstract
Intramedullary nailing is an established method for treating pertrochanteric fractures. However, the widespread use of this technique comes along with a variety of complications. We present a case of a 50-year-old female who presented to the emergency department suffering a left pertrochanteric fracture. She was treated with proximal femoral nailing and discharged home. Nine months later, she presented again to the emergency department with pain and an inability to bear weight. Imaging revealed the mechanical failure of the hip screw and loss of fracture fixation. Revision surgery included extraction of the broken hardware and a left hip hemiarthroplasty. The removed implant was sent for further evaluation. Fractographic analysis showed acute breakage due to bending and torsion forces acting on the screw with no relevant signs of metal fatigue. This biomechanical method is of great value for the surgeon and the implant manufacturer in order to understand the failure pattern and optimize future implants and fixation techniques. Improved implant biomechanical properties together with meticulous surgical technique constitute the cornerstones for optimal results.

Abstract
OBJECTIVE The implant failures of intertrochanteric fractures (ITF) after single-screw cephalomedullary nailing (CMN) were multifactorially associated with various related factors. However, a comprehensive scoring system for the early prediction of implant failures is still lacking. Thus, this study aims to establish a quantification scoring system (QSS) and verify whether the QSS is reliable for predicting implant failures in geriatric ITF patients. METHODS We established the QSS of geriatric ITF with single-screw cephalomedullary nailing within three days after surgery. The QSS included eight points totally at eight parameters, including bone quality, fracture type, reduction quality, and internal fixation placement. Then we retrospectively analyzed seventy-seven ITF (seventy-six patients) with surgical treatment between October 2016 and July 2020 in our hospital to verify whether the QSS scoring is suitable for predicting implant failures in ITF patients. RESULTS Implant failures were in fifteen fractures (fifteen patients), including six cases of cut-out, eight of pending cut-out, and one of cut-through. There were three cases with 2 points in QSS, three with 3 points, five with 4 points, four with 5 points in these fifteen fractures. No fractures were with 1 point in QSS, and no implant failures when scoring over 5 points in QSS. Except for QSS scoring, no significant difference was in the collected data by binary logistic regression analysis. QSS scoring was significantly associated with implant failures (Adjusted odds ratio (OR) = 7.312; 95% confidence intervals (CI), 2.561 to 20.871; p < 0.001). In the analysis of Spearman's correlation, there was a strong correlation between QSS scoring and the occurrences of implant failures (RQSS = -0.964, p < 0.001). The ROC result indicated that QSS was reliable in predicting implant failures at the cut-off of 5 points (AUC (the area under the curve) = 0.944; 95% CI, 0.866 to 0.983; p < 0.001). CONCLUSION The QSS is a useful early prediction of implant failures in geriatric ITF with cephalomedullary nailing fixation. QSS scoring more than 5 points can effectively reduce the risk of implant failures.

Abstract
This systematic review and meta-analysis aimed to analyse negative effects of smoking in orthopaedic and trauma patients. A PubMed search was carried out for studies published until July 2020 regarding effects of smoking on fracture risk, nonunion, infection after orthopaedic surgery, and persisting nonunion after scaphoid nonunion surgery. Random effects models calculated for outcome parameters, and relative risks (RR) with 95% confidence intervals are provided. No adjustments for covariates were made. Heterogeneity was assessed with Higgins’ I2, publication bias with Harbord’s p (Hp), sensitivity analysis performed on funnel plots and quality of studies was analysed using the Newcastle-Ottawa Scale. Of 3362 retrieved entries, 69 were included in the final analysis. Unadjusted RR for smokers to develop vertebral (six studies, seven entries; RR: 1.61; p = 0.008; I2 = 89.4%), hip (11 studies, 15 entries; RR: 1.28; p = 0.007; I2 = 84.1%), and other fractures (eight studies, 10 entries; RR: 1.75; p = 0.019; I2 = 89.3%) was significantly higher. Postoperative infection risk was generally higher for smokers (21 studies; RR: 2.20; p < 0.001; I2 = 58.9%), and remained upon subgroup analysis for elective spinal (two studies; RR: 4.38; p < 0.001; I2 = 0.0%) and fracture surgery (19 studies; RR: 2.10; p < 0.001; I2 = 58.5%). Nonunion risk after orthopaedic (eight studies; RR: 2.15; p < 0.001; I2 = 35.9%) and fracture surgery (11 studies; RR: 1.85; p < 0.001; I2 = 39.9%) was significantly higher for smokers, as was persisting nonunion risk after surgery for scaphoid nonunion (five studies; RR: 3.52; p < 0.001; I2 = 0.0%). Sensitivity analysis for each model reduced heterogeneity whilst maintaining significance (all I2 < 20.0%). Smoking has a deleterious impact on fracture incidence, and (subsequent) development of nonunions and postoperative infections.

Risk factors for implant failure of intertrochanteric fractures with lateral femoral wall fracture after intramedullary nail fixation. Injury 2021; 52:3397-3403. [PMID: 34321191 DOI: 10.1016/j.injury.2021.07.025] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 07/10/2021] [Accepted: 07/13/2021] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Few studies have specifically evaluated the comminution extent of lateral femoral wall (LFW) fracture and risk factors of implant failure in intertrochanteric fractures with LFW fracture. The aim of present study was to evaluate the influence of comminution extent of LFW fracture on implant failure and identify risk factors of implant failure in cases with LFW fracture after intramedullary fixation. METHODS This retrospective study included 130 intertrochanteric fracture with LFW fracture treated with intramedullary fixation at a teaching hospital over a 13-year period from January 2006 to December 2018. Demographic information, cortical thickness index, the reduction quality, status of medial support, position of the screw/blade and status of lateral femoral wall were collected and compared. The logistic regression analyzes was performed to evaluate risk factors of implant failure in intertrochanteric fractures with LFW fracture after intramedullary nail fixation. RESULTS 10 patients (7.69%) suffered from mechanical failure after intramedullary fixation. Univariate analyzes showed that comminuted LFW fracture (OR, 7.625; 95%CI, 1.437~40.446; p = 0.017), poor reduction quality (OR, 49.375; 95%CI, 7.217~337.804; p < 0.001) and loss of medial support (OR, 17.818; 95%CI, 3.537~89.768; p < 0.001) were associated with implant failure. After adjustment for confounding variables, the multivariable logistic regression analyzes showed that poor reduction quality (OR, 11.318; 95%CI, 1.126~113.755; p = 0.039) and loss of medial support (OR, 7.734; 95%CI, 1.062~56.327; p = 0.043) were independent risk factors for implant failure. Whereas, comminuted LFW fracture was not associated with implant failure (p = 0.429). CONCLUSIONS The comminution extent of the LFW fracture might influence the stability of intertrochanteric fractures; and intramedullary fixation might be an effective treatment method. Furthermore, poor reduction quality and loss of medial support could increaze the risk of implant failure in intertrochanteric fractures with LFW fractures after intramedullary fixation. Therefore, we should pay great emphasis on fracture reduction quality in future.

Abstract
Background and aim Acute treatment of young patients with proximal femoral fracture (PFF) remains a challenge for trauma surgeons due to major fracture displacement and heavy pain in clinical practice. Traditional methods have a variety of intrinsic defaults and cannot successfully manage the requirements of young patients. Benefiting from our anatomic research, we explored a new method of external fixation for this specific trauma and evaluated its feasibility and clinical outcomes. Material and methods Twenty-three young multiple-trauma patients with PFF were included in this study. Surgical treatment was applied using an external fixator via the anterior inferior iliac spine (AIIS). Electronic patient records, surgical characteristics, clinical outcomes, and complications were reviewed for each patient. Results The mean surgical time was 30.3 ± 7.3 min. The mean blood loss was 25.3 ± 10.8 mL. No iatrogenic nerve palsy, pin tract infection, failure of external fixation, or bedsores were observed. The postoperative visual analog scale score was significantly lower than the preoperative score (P < 0.01). The mean fracture reduction rate of the femur was 58.1 ± 17.0%, and the mean degree of reduction was 13.5 ± 6.9°. The mean external fixation time was 7.6 ± 4.0 days and intramedullary nailing was performed. The mean hospital, follow-up, and healing times were 28.7 ± 8.7 days, 23.5 ± 7.9 months, and 22.8 ± 5.7 weeks, respectively. The Harris Hip Score indicated excellent or good results in 20 patients. Conclusion Collectively, the results of this study revealed that external fixation via the AIIS is a safe, rapid, and effective method for acute treatment of PFF in young patients.

Acupuncture around the greater tuberosity of the femur combined with acupuncture at Xuehai acupoint alleviates the postoperative pain of elderly patients with intertrochanteric fracture. Am J Transl Res 2021; 13:8372-8378. [PMID: 34377330 PMCID: PMC8340171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Accepted: 03/28/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVE To determine the efficacy of acupuncture around the greater tuberosity of the femur (AGTF) combined with acupuncture at Xuehai acupoint for postoperative pain in elderly patients with intertrochanteric fracture. METHODS A total of 97 elderly patients with intertrochanteric fracture treated by proximal femoral nail antirotation (PFNA) were enrolled and randomly assigned into an observation group (Obs group, n=48) and a control group (Con group, n=49). The Obs group was treated by aspirin and AGTF combined with acupuncture at Xuehai acupoint for analgesia, while the Con group was treated by aspirin alone for analgesia. Both groups were treated for 7 consecutive days. The two groups were compared in pain degree (visual analog scale (VAS) score) after operation and hip joint function (Harris score), daily living ability (modified Barthel index (MBI) score), bone metabolism-related indexes, and inflammatory factors before and after treatment. RESULTS At 1-7 d after operation, both groups had gradually lower VAS scores, and at 5 and 7 d after operation, the Obs group had a lower VAS score than the Con group (both P<0.05). Additionally, at 2 months after operation, both groups had higher Harris scores and MBI scores, and the scores of the Obs group were both higher than those of the Con group (both P<0.05). At 7 d after operation, both groups showed a decrease in serum beta collagen degradation products (β-CTx) and an increase in procollagen type I amino-terminal propeptide (PINP) (both P<0.05), but the differences between the two groups in β-CTx and PINP were insignificant (P>0.05). Moreover, at 7 d after operation, both groups showed a decrease in C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α), and the two levels in the Obs group were lower than those in the Con group (both P<0.05). CONCLUSION For elderly patients with intertrochanteric fracture, AGTF combined with acupuncture at the Xuehai acupoint can more effectively relieve their postoperative pain and postoperative inflammation and more strongly promote their postoperative recovery of hip joint function.

Abstract
Background: InterTAN is a specific type of cephalomedullary nail with a twin interlocking de-rotation and compression screw, which has inherent ability of anti-rotation. Whether to tighten or not to tighten the preloaded setscrew to allow or not allow secondary sliding in InterTan nail is controversial in clinical practice. Methods: We retrospectively collected 4 nonunion cases of unstable pertrochanteric femur fractures (AO/OTA-31A2), all were treated with InterTan nail and the preloaded setscrew was tightened in order to prevent further secondary sliding and femoral neck shortening. Results: After 6 months to 2 years follow-up, the fractures showed nonunion in radiography and the patients complained slight to middle degrees of pain, and had to use walking stick assistant in activities of daily life. Tightening the pre-loaded setscrew to prevent postoperative secondary sliding as static constructs might keep the femoral neck length, but lose the opportunity of telescoping for fracture impaction, and take the risk of healing complications, such as fracture nonunion, femoral head cutout or nail breakage. Conclusions: As the harm outweighs benefit, we advocate the preloaded setscrew in InterTan nail should not be tightened in standard-obliquity pertrochanteric hip fractures (AO/OTA-31A1 and A2).

Abstract
Background The use of cephalo-medullary nails (CMN) is a widely accepted management option for the treatment of unstable per-trochanteric hip fractures. A growing body of literature has reported good functional and radiological outcomes in patients managed with a dynamic hip screw supplemented with a trochanteric stabilisation plate (DHS w/ TSP). However, a robust meta-analysis does not exist in the current literature comparing the two fixation methods. Purposes Management of these kinds of injuries is very challenging in orthopaedic practice, yet no strong evidence is in place to delineate which implant gives the best results. This meta-analysis is the first to determine the efficacy of CMN versus DHS w/ TSP. Methods An up-to-date literature search was performed using a predetermined search strategy and eligibility criteria. All suitable literature was appraised for methodological quality using the Cochrane’s collaboration tool. Hospital stay, operative time, intra-operative complication rate, mechanical failure rate, infection rates, revision rates and functional outcomes were all considered. Results A total of five studies were included in the meta-analysis. The results of this analysis suggest that CMN is only associated with lower revision rates when compared to DHS w/ TSP; however, no significant difference was found in terms of hospital stay, operative time, blood transfusion, complications rate and functional outcome. Conclusion Both CMN and DHS w/TSP proved to be reliable in the management of unstable per-trochanteric fractures; however, more extensive datasets are required to draw robust conclusions.

Abstract
Introduction Trochanteric femoral nail-advanced (TFNA) was introduced in the market with better nail design, better alloy (titanium molybdenum) and both sliding and static locking options of the helical blade. Although, it was devised to overcome the shortcomings of roximal Femoral Nail Anti-rotation (PFNA), it still can have complications, if the principles of fracture management are not met. Here, we report a case of a TFNA implant failure with helical blade cut-out in an elderly osteoporotic patient treated for inter-trochanteric femur fracture. To the best of our knowledge, this is the first report of helical blade cut-out wit TFNA nail in world literature. Case Report An 83-year-old female patient was treated with a TFNA nail for inter-trochanteric femur fracture (AO 31A2.1). An acceptable reduction and stable fixation were achieved. The position of the helical blade in the head was in the optimal position with a tip apex distance (TAD) of 29 mm. The patient presented to us 6 weeks later with implant failure with helical blade cut out after a history of fall. Cemented bipolar hemiarthroplasty with calcar reconstruction using a mesh was done. The patient was clinically asymptomatic and was walking full weight-bearing till her last follow-up at 14 months. Conclusion We can associate the failure seen in our case with an increased TAD of 29 mm, osteoporotic bone and a neutral to negative variance. Helical blade cut-out was seen as the blade was locked onto the nail with insufficient hold onto the osteoporotic head fragment which collapsed into varus, leading to cut-out. This case report emphasizes the importance of TAD, valgus reduction, and positive variance in avoiding implant failures, even with a newer implant like TFNA which was developed to improvise onto the shortcomings of PFNA nail.

[PMID: 33084250 PMCID: PMC7767684 DOI: 10.1111/os.12828] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 09/12/2020] [Accepted: 09/16/2020] [Indexed: 11/30/2022] Open
Abstract
Objective At present, cephalomedullary nail is the most frequently used implant in the management of intertrochanteric fractures around the world. The implant design and fixation techniques of the cephalomedullary nail have been continuously improved to ensure uncomplicated bone union during the past decade. However, a degree of reduction loss during bone healing is still not rare in clinical work. Many attributed this complication to misoperation during the surgery and hold that a series of techniques and tips could help to avoid the loss of reduction. However, until now there has been no research to explore whether the reduction loss after the operation can be fully prevented in the best cases. The purposes of the study are as follows: (i) to evaluate the efficiency of the current established CMN techniques; (ii) to quantify the loss of reduction under an appropriately implanted CMN to anatomically realigned intertrochanteric fractures; and (iii) to explore the possible underlying causes for the inevitable loss of reduction. Methods In the retrospective study, 163 consecutive cases with the intertrochanteric fractures fixed with standard cephalomedullary nail technique were reviewed. The anatomical reduction and optimal positioning of the nail were confirmed by postoperative imaging. The fracture types ranged from 31‐A1.1–2.3 according to the OTA/AO fracture classification. One hundred and fifteen cases with stable fracture types (31A1.1–2.1) were allocated to Group A, and 48 cases with unstable 31A2.2–2.3 fracture types were allocated to Group B. The radiological measurements included femoral neck shortening, loss of the neck‐shaft angle, cutout, and cut‐through of the blade. The outcomes between postoperative and 1 year after the operation were evaluated and compared. Results The patients consisted of 66 males and 97 females with an average age of 69.4 (range: 46–78, SD: 14.6) years. At the 1‐year follow‐up, no fixation failure or nonunion was observed in each group. The mean femoral neck shortening and loss of the neck‐shaft angle were 4.47 mm (range: 0.43–17.68, SD: 3.71) and 5.4° (range: 0.51–19.10, SD: 3.58) separately. The mean cutout and cut‐through were 1.84 mm (range: 0.24–11.30, SD: 2.33) and 1.25 mm (range: 0.51–10.29, SD: 1.74). The average femoral neck shortening and loss of the neck‐shaft angle were higher in Group B than Group A. Among the 23 cases with the femoral neck shortening more than 10 mm, 19 cases (16.5%) were from Group A and four cases (8.3%) were from Group B. There were nine (7.8%) cases with the loss of the neck‐shaft angle more than 10° in Group A and six (12.5%) cases in Group B. Conclusions Current established CMN techniques are efficient in treating intertrochanteric femoral fracture. However, even with currently consensual techniques of cephalomedullary nail, the process of fracture healing still risks the loss of reduction, although the migration of the blade could be minimized. This situation may associate with the intrinsic design of the CMN and further improvement is still needed.
