Introduction: High-energy femoral neck fractures in young patients can be devastating, with the risk of osteonecrosis, nonunion, malunion and lifelong morbidity. The aim of this study is to define the effects of patient, fracture and surgical factors on the outcome of high-energy femoral neck fractures in patients aged from 15 to 50 years. Methods: A retrospective review was conducted of high-energy femoral neck fractures in patients aged 15–50 managed surgically at a Level 1 Trauma Centre, using a prospectively recorded trauma database. Low energy trauma (including falls from <1 m), medical conditions adversely affecting bone density, and pathological fractures were excluded. A clinical and radiological review was performed. The primary outcome measures were the development of osteonecrosis or nonunion leading to total hip arthroplasty (THA). Secondary outcome measures included osteotomy or other surgical procedures, quality of reduction and malunion. Results: 32 patients meeting the inclusion criteria were identified between January 2008 and July 2015. The mean follow-up was 58.5 months (range 980–3,048 days). 3 patients (9.4%) required THA. No other surgical procedures were performed. None of the 29 other patients developed radiologically apparent osteonecrosis. Fracture type, displacement, anatomical reduction and fixation type were not statistically significant risk factors affecting these outcomes. For all patients, an average of 8% loss of femoral neck height and 10% femoral neck offset were seen. Conclusions: At a mean 4.9-year follow-up, the incidence of high-energy femoral neck fractures leading to THA was 9.4%, as a consequence of osteonecrosis or nonunion. Malunion was common.

Abstract Background Despite being a commonly encountered injury in orthopedic practice, controversy surrounds the methods of optimal internal fixation for femoral neck fractures (FNF) in young patients. The objective of the present study is to compare complication rates and failure mechanisms for surgical fixation of FNF using fully threaded headless cannulated screws (FTHCS) versus partial threaded cannulated screws (PTS) in young adults. Methods A total of 75 patients (18–65 years old) with FNF were prospectively treated with close reduction and internal fixation using three parallel FTHCS and compared to a historical control case-matched group (75 patients) with FNF treated by PTS fixation. After 2 years follow-up, rates of fixation failure (including varus collapse, fracture displacement, and femoral neck shortening), nonunion, and avascular necrosis of the femoral head (ANFH) were compared between the two cohorts. The demographic, follow-up information, and radiological images were assessed by independent blinded investigators. Results Patient demographics and fracture patterns were similar in the two patient groups. The overall fixation failure rates were 8% (6/75) in the FTHCS cohort, which was significantly lower than the 25.3% (19/75) seen in the PTS group. Rates of nonunion and ANFH were significantly lower in the FTHCS group when compared to the PTS control group. When stratified by injury severity (high-energy vs. low-energy fractures), the rate of fixation failure was significant lower with the use of FTHCS when compared with PTS for high-energy fractures while there was no difference in the rates of nonunion or ANFH for high or low-energy fracture patterns. Unique to the FTHCS cohort was an atypical screw migration pattern with varus collapse (6/75, 8%). Conclusions The results show that FTHCS fixation could significantly reduce the complication rate of young patients with FNF, especially in high-energy fracture patterns (Garden III–IV, Pauwels III, or vertical of the neck axis (VN) angle ≥ 15°). There was also confirmation that the modes of fixation loosening in the FTCHS group, including screw “medial migration” and superior cutout, were different from the screw withdrawal pattern seen in the PTS cohort. Trial registration The study was retrospectively registered at www.Chictr.org.cn (ChiCTR-IPR-1900025851) on September 11, 2019.

Abstract Background Femoral neck fractures in adults younger than age 50 years are uncommon and often the result of high energy trauma. They account for only 2-3% of all femoral neck fractures. Femoral neck fractures are associated with aging and osteoporosis and can occur after relatively trivial trauma in elderly patients. femoral neck fractures are associated with higher incidences of femoral head osteonecrosis and nonunion. Fixation options include cannulated screws, non parallel cannulated screws, medial augmentation plate, and fixed angle femoral neck fixation implants. A systematic review of literature done to evaluate which technique is better. Methods After literature search thirteen articles were found and were reviewed to evaluate final outcome of fixation of neck femur fractures by cannulated screws, non parallel cannulated screws, medial augmentation plate, and fixed angle femoral neck fixation implants. Results After evaluation of all studies the incidence of nonunion, osteonecrosis of femoral head, implant failure & revesion surgery is lower in comparing Targon plate with multiple cannulated screws while we need further studies for application of non parallel screws and medial plate. Conclusion Targon plate recorded low incidence of complications in the final outcome in comparison with multiple cannulated screw while we need further studies for application of Non parallel screws and medial plate.

Purpose: Femoral neck fractures in young patients are associated with increase complication risk. The objective of this study was to evaluate the results of quadratus femoris muscle pedicle grafting in the treatment of ununited femoral neck fractures. Methods: This study includes 16 patients with ununited femoral neck fractures treated with quadratus femoris muscle pedicle graft. 7 patients had neglected femoral neck fractures while 9 had ununited femoral neck fractures after fixation. Quadratus femoris muscle with 2 × 1 × 1 cm (length-width-height) bone in its insertion was elevated and placed in the posterior cortex of the femoral neck with additional cancellous graft from the posterior iliac bone. The graft was fixed with 3.5-mm cortical screws. Results: The average follow-up period was 96 weeks and the radiological union occurred at an average of 7 months. The femoral inclination of all patients was 128.5° ± 3.9° with an average 7 (range 0–35) mm thigh atrophy in the last follow-up visit. Only 1 patient (6%) had avascular necrosis of the femoral head and was treated with hip arthroplasty. Conclusions: Quadratus femoris muscle pedicle grafting provides better stability and blood supply in ununited femoral neck fractures. Achieving fracture union provides better clinical and functional results in the treatment of femoral neck fractures.

Abstract BackgroundThe femoral neck system (FNS) is a novel internal fixation system for the treatment of femoral neck fractures (FNFs). However, there is a paucity of literature looking at the factors associated with early failure of the FNS (EFFNS) in patients with FNFs. In this study, we aimed to investigate the prevalence of EFFNS and identify risk factors for EFFNS in patients with FNFs.MethodsWe retrospectively analysed 62 patients who presented with intracapsular neck femur fractures and underwent FNS fixation between 2019 and 2021. Demographic, clinical characteristics and radiographic features are described. Multifactor logistic regression analysis was used to analyse the different influencing factors.ResultsOf the 62 FNFs, 10 patients (16.1%) developed early failures after FNS fixation, including 6 cases of severe femoral neck shortening, 1 case of avascular necrosis of the femoral head, 1 case of nonunion, and 2 cases of screw-out. In the failure group, all patients were younger than 65 years old. The proportion was significantly higher than the 59.6% in the healing group (P = 0.012). However, we found that Garden classification (P = 0.464) and age (P = 0.128) were not statistically significant risk factors for EFFNS. ConclusionsOur study demonstrated that age was an important factor influencing EFFNS. However, we cannot determine whether age and Garden classification are independent risk factors for EFFNS in the treatment of FNFs.Trial registration: ChiCTR2100051360.

Objective To compare the clinical outcomes of primary metal-on-metal total hip replacement (MoM-TR) converted to uncemented total hip replacement (UTR) or cemented total hip replacement (CTR) in patients with femoral neck fractures (AO/OTA: 31B/C). Methods Patient data of 234 UTR or CTR revisions after primary MoM-TR failure from March 2007 to January 2018 were retrospectively identified. Clinical outcomes, including the Harris hip score (HHS) and key orthopaedic complications, were collected at 3, 6, and 12 months following conversion and every 12 months thereafter. Results The mean follow-up was 84.12 (67–100) months for UTR and 84.23 (66–101) months for CTR. At the last follow-up, the HHS was better in the CTR- than UTR-treated patients. Noteworthy dissimilarities were correspondingly detected in the key orthopaedic complication rates (16.1% for CTR vs. 47.4% for UTR). Statistically significant differences in specific orthopaedic complications were also detected in the re-revision rate (10.3% for UTR vs. 2.5% for CTR), prosthesis loosening rate (16.3% for UTR vs. 5.9% for CTR), and periprosthetic fracture rate (12.0% for UTR vs. 4.2% for CTR). Conclusion In the setting of revision of failed primary MoM-TR, CTR may demonstrate advantages over UTR in improving functional outcomes and reducing key orthopaedic complications.

OBJECTIVEA multicenter, prospective, randomized equivalence trial comparing a thoracolumbosacral orthosis (TLSO) to no orthosis (NO) in the treatment of acute AO Type A3 thoracolumbar burst fractures was recently conducted and demonstrated that the two treatments following an otherwise similar management protocol are equivalent at 3 months postinjury. The purpose of the present study was to determine whether there was a difference in long-term clinical and radiographic outcomes between the patients treated with and those treated without a TLSO. Here, the authors present the 5- to 10-year outcomes (mean follow-up 7.9 ± 1.1 years) of the patients at a single site from the original multicenter trial.METHODSBetween July 2002 and January 2009, a total of 96 subjects were enrolled in the primary trial and randomized to two groups: TLSO or NO. Subjects were enrolled if they had an AO Type A3 burst fracture between T-10 and L-3 within the previous 72 hours, kyphotic deformity < 35°, no neurological deficit, and an age of 16–60 years old. The present study represents a subset of those patients: 16 in the TLSO group and 20 in the NO group. The primary outcome measure was the Roland Morris Disability Questionnaire (RMDQ) score at the last 5- to 10-year follow-up. Secondary outcome measures included kyphosis, satisfaction, the Numeric Rating Scale for back pain, and the 12-Item Short-Form Health Survey (SF-12) Mental and Physical Component Summary (MCS and PCS) scores. In the original study, outcome measures were administered at admission and 2 and 6 weeks, 3 and 6 months, and 1 and 2 years after injury; in the present extended follow-up study, the outcome measures were administered 5–10 years postinjury. Treatment comparison between patients in the TLSO group and those in the NO group was performed at the latest available follow-up, and the time-weighted average treatment effect was determined using a mixed-effects model of longitudinal regression for repeated measures averaged over all time periods. Missing data were assumed to be missing at random and were replaced with a set of plausible values derived using a multiple imputation procedure.RESULTSThe RMDQ score at 5–10 years postinjury was 3.6 ± 0.9 (mean ± SE) for the TLSO group and 4.8 ± 1.5 for the NO group (p = 0.486, 95% CI −2.3 to 4.8). Average kyphosis was 18.3° ± 2.2° for the TLSO group and 18.6° ± 3.8° for the NO group (p = 0.934, 95% CI −7.8 to 8.5). No differences were found between the NO and TLSO groups with time-weighted average treatment effects for RMDQ 1.9 (95% CI −1.5 to 5.2), for PCS −2.5 (95% CI −7.9 to 3.0), for MCS −1.2 (95% CI −6.7 to 4.2) and for average pain 0.9 (95% CI −0.5 to 2.2).CONCLUSIONSCompared with patients treated with a TLSO, patients treated using early mobilization without orthosis maintain similar pain relief and improvement in function for 5–10 years.
