Valgus-impacted subcapital neck of femur fractures: a systematic review, meta-analysis with cost analysis of fixation in-situ versus nonoperative management. Hip Int 2024; 34:260-269. [PMID: 38116748 PMCID: PMC10935617 DOI: 10.1177/11207000231210240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 04/01/2023] [Indexed: 12/21/2023]
Abstract
BACKGROUND The management of the valgus-impacted neck of femur fracture (AO/OTA 31-B1) remains contentious. The objective of this study was to determine whether operative intervention is cost-effective. METHODS We conducted a systematic review using electronic databases (Medline, Embase, Cochrane, Ebsco, Scholar) identifying studies published in the English language concerning valgus-impacted neck of femur fractures until June 2022. Additional studies were identified through hand searches of major orthopaedic journals, and bibliographies of major orthopaedic textbooks. MeSH terms (hip fracture and femoral neck fracture) and keywords (undisplaced, valgus-impacted, valgus, subcapital, Garden) connected by the Boolean operators "AND" and "OR" were used to identify studies. 2 reviewers independently extracted the data using standardised forms and recording spreadsheet. Methodological validity prior to inclusion in the review using standardized critical appraisal instruments from the Joanna Briggs Institute Meta-analysis of Statistics Assessment and Review Instrument. Meta-analysis was undertaken. Outcome measures were rate of displacement, avascular necrosis, non-union, mortality and requirement of further operative intervention. A cost utility analysis was then conducted to compare the 2 groups on the basis of the cost of initial treatment and the potential requirement of secondary intervention to hemiarthroplasty. RESULTS 47 studies met the inclusion criteria. Meta-analysis data demonstrated a significant difference in the displacement rate of 22.8% and 2.8% between the nonoperative and internal fixation groups respectively (p = 0.05). The overall incidence of further operative intervention for each group was 23% and 10% respectively. There was no significant difference with respect to avascular necrosis, mortality or union rates. The cost utility analysis revealed nonoperative management to be approximately 60% more costly than initial internal fixation when the costs of subsequent surgery were included. CONCLUSIONS This meta-analysis of the existing literature concludes that whilst nonoperative management is possible for valgus impacted neck of femur fractures, it is associated with higher complication rates and greater expense than management by internal fixation.

Abstract
BACKGROUND Hip fracture is a common musculoskeletal injury in the elderly requiring surgery worldwide. The operative mainstay of intra-capsular hip fractures is arthroplasty with a smaller proportion for fixation. AIM To determine the most beneficial method of fixation for patients with intra-capsular hip fractures. METHODS A registered audit from 2012-2018 was conducted on all intra-capsular hip fractures treated with 2 commonly used fixation methods. Patient notes, electronic records and clinical codes for cost benefit were evaluated. A validated quality of life measure was collected at least 1 year after surgery. RESULTS A total of 83 patients were identified with intra-capsular fractures undergoing fixation during the retrospective period. There were 47 cannulated cancellous screw and 36 sliding hip screw fixations with the case mix comparable for age, gender, co-morbidities and fracture configuration. There was no significant difference in blood loss, tip apex distance, radiation exposure, length of stay, radiological union time, collapse, avascular necrosis or re-operation between fixation methods. Logistic regression analysis demonstrated displaced intracapsular hip fractures correlated significantly with an undesirable outcome conferring a relative odds ratio of 7.25. There were 9 (19%) and 4 (11%) patients respectively, who required re-operation. There was no significant difference in health resource group tariff and implant cost with comparable EQ-5D and visual analogue scores. CONCLUSION No significant advantage was identified with differing fixation type, but irrespective there were a high number of patients requiring re-operation. This was predicted by initial fracture displacement and patient age. Arthroplasty may need to be carefully considered for health economics and patient benefit.

Abstract
BACKGROUNDS This study aimed to analyze the clinical outcomes of femoral neck fractures (FNF) in patients treated with a femoral neck system (FNS, DePuy Synthes), which is a recently introduced device. METHODS This retrospective cohort study of 43 patients who underwent osteosynthesis using FNS for FNF between July 2019 and June 2021 with a minimum follow-up of 6 months. The researchers examined the patients' demographic factors and radiologically evaluated the fracture type and fixation status, bone union, and postoperative complications. RESULTS Of 43 patients, 25 were female, and the patients' mean age and body mass index were 62.1 years and 22.5 kg/m2, respectively. According to the Association of Osteosynthesis/Orthopaedic Trauma Association (AO/OTA) classification, the most common fracture types were 31B1.1 and B1.2 (13 cases each), followed by B2.3, B2.1, and B2.2 (seven, five, and four cases, respectively). Radiological bone union was confirmed in 39 patients (90.7%), and the mean time to union was 3.6 months. Two cases of nonunion, one case of lag screw cut-out, and one case of osteonecrosis were confirmed; all four cases later underwent arthroplasty. The mean time to reoperation was 4.5 months. Meanwhile, five patients underwent implant removal after the bone union, and distal locking screw stripping was noted in three patients. All three patients required metal plate cutting to remove the implants. CONCLUSIONS Osteosynthesis of FNF using the newly introduced FNS showed favorable clinical outcomes and no specific hardware-related complications were reported during the follow-up. However, attention must be paid to the issue regarding distal locking screw failure during hardware removal.

Abstract
BACKGROUND This study aimed to evaluate the clinical efficacy of the femoral neck system alone or in combination with a cannulated screw compared with other internal fixation methods for treating femoral neck fractures. We further investigated the predictive effects of tip-apex distance (TAD) on clinical efficacy. METHODS Data from 129 young adults with femoral neck fractures followed up at The Second Affiliated Hospital of Fujian Medical University between January 2016 and June 2022 were retrospectively collected. The patients were categorized into four groups based on the different internal fixation methods. Analysis and comparisons of the four group were performed according to age, ASA score, operation time, blood loss, fracture classification, fracture healing time, Harris score, TAD value, presence of complications (osteonecrosis of the femoral head, screw failure, and femoral neck shortening), and changes in the neck-shaft angle. RESULTS All 129 patients were followed up for at least one year. The group who received treatment with the femoral neck system combined with a cannulated screw exhibited the shortest fracture healing time. Differences were observed in the change of neck-shaft angle among the four groups (P < 0.001), with the smallest change observed in the aforementioned group (0.76 ± 0.54°). The femoral neck shortening was also lower in groups with the femoral neck system or combined with a cannulated screw. At the last follow-up surgery, the combined treatment group achieved the highest HHS score. Subgroup analysis revealed that when the TAD was less than 25 and 49 mm for the femoral neck system and combined groups, respectively, there was less femoral neck shortening, less change in the neck-shaft angle, and a higher HHS score. CONCLUSIONS The femoral neck system alone or combined with a cannulated screw demonstrated better short-term efficacy in the treatment of femoral neck fractures. Furthermore, TAD may serve as a predictive indicator of the potential success of femoral neck fracture treatment.

High Percentage of Complications and Re-Operations Following Dynamic Locking Plate Fixation with the Targon ® FN for Intracapsular Proximal Femoral Fractures: An Analysis of Risk Factors. Medicina (B Aires) 2022; 58:medicina58121812. [PMID: 36557015 PMCID: PMC9781073 DOI: 10.3390/medicina58121812] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 12/04/2022] [Accepted: 12/07/2022] [Indexed: 12/13/2022] Open
Abstract
The ideal surgical treatment of femoral neck fractures remains controversial. When treating these fractures with internal fixation, many fixation constructs exist. The primary aim of this study was to evaluate the incidence and specific risk factors associated with complication and re-operation following fixation of intracapsular proximal femoral fractures using the Targon-FN system (B.Braun Melsungen AG). A secondary aim was to identify if lateral prominence of the implant relative to the lateral border of the vastus ridge was a specific risk factor for elective plate removal. Methodically, a retrospective case series was conducted of all consecutive adult patients treated at a single level 1 trauma center in Switzerland for an intracapsular proximal femoral fracture with the Targon-FN. Demographic data were collected. Patients with a follow-up of less than three months were excluded. Complications as well as plate position were recorded. Statistical analysis to identify specific risk factors for re-operation and complications was performed. In result, a total of 72 cases with intracapsular femoral neck fractures were treated with the Targon-FN locking plate system between 2010 and 2017. Thirty-four patients (47.2%) experienced one or more complications. The most common complication was mechanical irritation of the iliotibial band (ITB) (23.6%, n = 17). Complications included intraarticular screw perforation (6.9%, n = 5), avascular necrosis (5.6%, n = 4), non-union (5.6%, n = 4) among others. In total, 46 re-operations were required. Younger age, fracture displacement and time to postoperative weight bearing were identified as risk factors for re-operation. In conclusion, intracapsular femoral neck fractures treated with the Targon-FN system resulted in a high rate of post-operative complication and re-operation. Statistical analysis revealed patient age, fracture displacement, time to postoperative full weight bearing were risk factors for re-operation. The main limitation is the limited number of cases and a short follow-up of less than 12 months in a subgroup of our patients.

Abstract
Background: Avascular necrosis (AVN) of the femoral head often requires surgical treatment and is often associated with femoral neck fractures. We conducted a systematic review and meta-analysis of recent research on the risk of AVN following the stabilization of fractured femoral neck with implants in PubMed. We assessed the effect of age on AVN incidence among patients aged > 50 and younger, depending on fracture type, Garden stage, Pouwels degree, Delbet stage, and age category. We followed PRISMA guidelines. Relevant studies were defined as research articles describing real-world studies reporting on the risk of AVN following primary surgical fracture stabilization with implants, published between 1 January 2011 and 22 April 2021. Fifty-two papers met the inclusion criteria, with a total of N = 5930 with surgically managed fractures. The pooled mean AVN incidence was significantly higher among patients with displaced fractures (20.7%; 95% CI: 12.8−28.5%) vs. those with undisplaced fractures (4.7%; 95% CI: 3.4−6.0%). No significant correlation was observed between AVN incidence weighted by sample size and time interval from injury to surgery (p = 0.843, R2 = 0.01). In conclusion, the risk of AVN following femoral neck fractures was generally high, especially in patients with displaced fractures. The time from injury to surgery did not correlate with AVN incidence.

Abstract
Avascular necrosis (AVN) of the femoral head is caused by disruption of the blood supply to the proximal femur. The alterations in the blood supply may occur following a traumatic event or result from a non-traumatic cause. Femoral neck fracture and hip dislocation and associated surgical procedures, corticosteroid therapy, and alcohol abuse frequently lead to AVN development. Type of fracture (displaced or undisplaced) and time between injury and surgery are the most critical factors in assessing the risk of developing AVN. Diagnosis of AVN can be established based on patients’ complaints, medical history, and radiographic findings. There is no consensus on the treatment of patients with AVN to date. Non-surgical methods are dedicated to patients in the early pre-collapse stages of the disease and consist of pharmacotherapy and physiotherapy. Surgery is recommended for patients with advanced disease.

Abstract
Objective To investigate the efficacies of Femoral Neck System (FNS) and the three cannulated screws fixation (3CS) as therapeutic options for femoral neck fractures. Method This was a retrospective study involving 69 patients (26 males and 43 females; mean age of 54.9 years (range, 28–66 years)) subjected to either FNS or 3CS for femoral neck fracture therapy. These patients were treated in our hospital from October 2019 to May 2020. Patient follow up was done at 1, 2, 3 and 6 months. During the short‐term (6 months) follow‐up period, surgical procedures for the two groups and incidences of complications were analyzed. Perioperative parameters were recorded and analyzed. Postoperative hip joint functions were measured and compared using the Harris score. The assessed perioperative parameters included surgical time, hemoglobin loss, fluoroscopy duration, hospitalization length and hospitalization cost. The main complications at last follow‐up (6 months) included varus tilting, femoral neck shortness, and implant removal. Results Differences in the number of patients, age, Garden type of fracture and time from injury to surgery between the two groups were not significant (P > 0.05). With regards to perioperative parameters, compared to 3CS, FNS treatment performed better in surgical time (60.00 ± 12.44 vs 76.81 ± 13.10 min, P = 0.000), blood loss (13.67 ± 8.02 vs 16.58 ± 4.16 g/L, P = 0.059) and fluoroscopy time (39.73 ± 9.57 vs 58.14 ± 9.15 s, P = 0.000). Differences in hospitalization length and cost between the groups were not significant (P > 0.05). During the whole follow‐up period, all patients did not exhibit dysfunction, pulmonary embolism or even death as a result of long‐term immobilization of affected limbs. Surgical incisions for all patients healed well without infections. During the 6‐month follow‐up period, the FNS group exhibited a higher Harris score (84.61 ± 3.42 vs 78.67 ± 3.72, p = 0.000). In addition, treatment‐associated complications (FNS vs 3CS) included femoral neck varus tilt (3.03% vs 11.11%), femoral neck shortness (6.06% vs 13.89%), and implant removal (0% vs. 13.89%). Implant removal rate for the FNS group was significantly less than that of the 3CS group (P = 0.026). Differences in incidences of femoral neck varus tilt (P = 0.196) and femoral neck shortness (P = 0.282) between the two groups were not significant. However, the difference in number was significant (FNS group was less). Conclusion FNS treatment is associated with a smaller surgical trauma, stronger stability, and reductions in post‐operative complication incidences, therefore, it is a potential therapeutic option for femoral neck fractures.

Osteosynthesis of non-displaced femoral neck fractures in the elderly population using the femoral neck system (FNS): short-term clinical and radiological outcomes. J Orthop Surg Res 2021; 16:477. [PMID: 34348753 PMCID: PMC8336369 DOI: 10.1186/s13018-021-02622-z] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 07/17/2021] [Indexed: 12/29/2022] Open
Abstract
Background Femoral neck fractures (FNF) are frequent in the elderly population, and surgical management is indicated in the vast majority of cases. Osteosynthesis is an alternative to arthroplasty for non-displaced FNF. Triple screw construct (TS) and the dynamic hip screw system (DHS) are considered gold standards for osteosynthesis. The newly available femoral neck system (FNS) currently lacks evidence as to whether it is a valid alternative to TS and DHS. The purpose of this study was to evaluate the short-term clinical and radiological outcomes after non-displaced (Garden I and II) FNF osteosynthesis using TS, DHS, and FNS. Methods All the patients of the author’s institution aged ≥ 75 years with a non-displaced (Garden I and II) FNF eligible for osteosynthesis between November 2015 and December 2019 were included in this single-center retrospective non-randomized study. Patients were treated with either TS, DHS, or FNS depending on the surgeon’s preference. Clinical data (age, gender, ASA score, duration of surgery, need for blood transfusion and number of packed red blood cells transfused, surgical site complications, length of stay, discharge location, postoperative medical complications and readmission within 30 days, and mortality within 3 months) were extracted from the patients’ charts. The radiological analysis assessed the fracture classification, fracture impaction, and proximal femur shortening at 3 and 6 months using the institutional imaging software. Results Baseline characteristics in the TS (n = 32), DHS (n = 16), and FNS (n = 15) groups were similar with respect to age (mean 85 years), gender (female to male ratio 4:1), and ASA score. There were no significant differences across the groups for the need for blood transfusion, surgical site complications, length of stay, postoperative medical complications and readmission within 30 days, discharge location, and mortality within 3 months. The duration of surgery was significantly lower in the FNS group (43.3 vs 68.8 min; p < 0.001). The radiological assessment found similar impaction (5.2 mm ± 4.8) and shortening (8.6 mm ± 8.2) in all groups that did not seem to progress after 3 months. Conclusion The FNS appears to be a valid alternative implant for FNF osteosynthesis and is associated with a shorter operative time than TS and DHS. Short-term clinical and radiological outcomes of FNS are similar to TS and DHS implants. Further long-term multicenter randomized studies are however necessary to confirm these first results.

Abstract
Introduction There is no consensus regarding the optimal device for displaced intracapsular hip fractures. This retrospective study compared two techniques (1) cannulated cancellous screw (CCS), and (2) Targon Femoral Neck (TFN) plate. Materials and methods Data regarding gender, operational data, complications, pain, Quality of life and function scores were retrieved. Results 103 patients were included, 42 were treated using CCS, compared to 61 treated using TFN. Operative time shorter for CCS (p = 0.019). Complication rates were not different (p > 0.05). Conclusion As CCS method take shorter operating time and reduced costs, CCS should be used for the treatment of displaced ICHF.

Current Trends in the Evaluation and Management of Nondisplaced Femoral Neck Fractures in the Elderly. J Am Acad Orthop Surg 2021; 29:e154-e164. [PMID: 33201046 DOI: 10.5435/jaaos-d-20-00349] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Accepted: 09/14/2020] [Indexed: 02/01/2023] Open
Abstract
Nondisplaced (Garden I and II) femoral neck (FN) fractures are commonly encountered by the practicing orthopaedic surgeon. Although these fractures are primarily classified based on the AP radiograph, the lateral radiograph should be closely scrutinized as well because posterior tilt has emerged as a consistent predictor of fixation failure. Internal fixation has for many years been the standard of care, with both cannulated screws and the sliding hip screw representing acceptable options. However, the outcomes after fixation of Garden I and II FN fractures have not been uniformly positive, with the rates of revision surgery ranging from 8% to 27%. Complications after fixation of nondisplaced FN fractures include nonunion, fixation failure, osteonecrosis, and femoral shortening causing inferior hip function. For these reasons, arthroplasty is increasingly considered a viable option in the treatment of these fractures, especially in the presence of factors that predispose to failure after fixation. Novel devices for FN fixation have recently been developed, although clinical data supporting their use are sparse at the present time.

Comparison of Ordinary Cannulated Compression Screw and Double-Head Cannulated Compression Screw Fixation in Vertical Femoral Neck Fractures. BIOMED RESEARCH INTERNATIONAL 2020; 2020:2814548. [PMID: 33457404 PMCID: PMC7787733 DOI: 10.1155/2020/2814548] [Citation(s) in RCA: 40] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Revised: 12/07/2020] [Accepted: 12/15/2020] [Indexed: 12/16/2022]
Abstract
Background The treatment of vertical femoral neck fractures in young patients remains a challenge. This study is aimed at comparing ordinary cannulated compression screw (OCCS) and double-head cannulated compression screw (DhCCS) fixation in vertical femoral neck fractures both clinically and biomechanically. Materials and Methods Clinically, the radiographs of 81 patients with Pauwel's III femoral neck fractures, including 54 fractures fixed with three parallel OCCSs and 27 fractures fixed with three parallel DhCCSs, were reviewed retrospectively. Complications consisting of fixation failure (screw loosening, obvious fracture displacement, varus deformity, or femoral neck shortening), bony nonunion, and avascular necrosis (AVN) were determined. Biomechanically, twenty synthetic femur models of vertical femoral fractures with an 80° Pauwel's angle were divided into two groups and subsequently fixed with three parallel OCCSs or DhCCSs. All specimens were tested for axial stiffness, load to 5 mm displacement, and a maximum load to failure with a loading rate of 2 mm/min. Results Clinically, 22 fractures in the OCCS group experienced fixation failure, including 19 screw loosening, 18 femoral neck shortening, 14 varus deformities, and 8 obvious fracture displacements, whereas only 4 fractures experienced fixation failure in the DhCCS group, including 3 screw loosening, 3 femoral neck shortening, 3 varus deformities, and 1 obvious fracture displacement. Additionally, 11 fractures in the OCCS group exhibited nonunion, whereas only 3 in the DhCCS group exhibited nonunion. Nine fractures with AVN were noted in the OCCS group, whereas only 1 was observed in the DhCCS group. Biomechanically, the axial stiffness of the DhCCS group was greater than that of the OCCS group (154.9 ± 6.81 vs. 128.1 ± 7.41 N/mm), and the load to 5 mm displacement was also significantly greater in the DhCCS group (646.1 ± 25.87 vs. 475.8 ± 21.46 N). Moreover, the maximum load to failure in the DhCCS group exhibited significant advantages compared with that of the OCCS group (1148 ± 39.47 vs. 795.9 ± 51.39 N). Conclusion Our results suggested that using three DhCCSs improved the outcome of vertical femoral neck fractures compared to three OCCSs, offering a new choice for the treatment of femoral neck fracture.

Abstract
The aim of this case report is to present an unusual mechanism of failure of a dynamic locking plate (DLP), previously reported in dual lag screw proximal femoral nails. A 78-year-old female patient experienced a displaced right femoral neck fracture (FNF) which was managed with DLP. At the postoperative sixth- week appointment, her hip radiographs showed that two of three telescoping screws had slid within the telescrew barrel, and one screw was fully extended and cutting through the femoral head. At the third-month checkup, radiographs revealed an unhealed FNF and 12 mm sliding on all three telescoping screws. At the final 11th-month follow-up, two screws were completely collapsed and the previously nonpenetrating screw was partially extended and cutting through the femoral head. Femoral neck shortening and femoral neck nonunion were noticed as well. In conclusion, the postoperative course of the case supports the hypothesis of a specific pattern of DLP failure resembling reversed Z- and Z-effects found in dual lag screw proximal femoral nails.

A Comparison of Dynamic Hip Screw and Two Cannulated Screws in the Treatment of Undisplaced Intracapsular Neck Fractures-Two-Year Follow-Up of 453 Patients. J Clin Med 2019; 8:jcm8101670. [PMID: 31614881 PMCID: PMC6832900 DOI: 10.3390/jcm8101670] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Accepted: 10/02/2019] [Indexed: 12/01/2022] Open
Abstract
One of the most common fractures is that of the intracapsular femoral neck; however, the optimal implant for head-preserving treatment remains controversial. The aim of the study was to compare the outcomes of treating undisplaced intracapsular femoral neck fractures with either the dynamic hip screw (DHS) or the double cannulated screw fixation (CSFN). This retrospective cohort study analysed the data of 453 patients, with a mean age of 76.9 years, whose intracapsular fractures were treated with the DHS or CSFN between 2005 and 2013. The analysis focused on the rates of revision surgeries and complications; however, the impact of confounding exogenous factors, such as smoking and alcohol, were also considered. No significant difference was observed between the revision rates of DHS and CSFN (15.0% vs. 13.1%; p = 0.565). According to the complication rate, the advantage in favour of the CSFN was not significant (20.5% vs. 13.1%, p = 0.038). The use of the DHS was associated with a 13 min longer surgery (p < 0.0001) and a one day longer hospitalization (p = 0.242). Excessive consumption of alcohol was associated with an increased incidence of avascular necrosis (18.6% vs. 8.7%, p = 0.035). The choice of implant showed no significant impact on rates of revision surgery and complications. In terms of socioeconomic factors, the fixation with two cannulated screws was more favourable, making it the more cost-effective and less stressful method.

Abstract
INTRODUCTION The purpose of this study was to determine factors that affect the early failure of femoral neck fracture healing after internal fixation with a dynamic locking plate implant. PATIENTS AND METHODS Retrospective analysis of all cases of femoral neck fracture (FNF) primarily treated with dynamic locking plate implant from 04/2014 to 04/2017 with a minimum of 6 month follow-up. For the purpose of the study age, sex and time from admission to surgery were retrieved from the hospital medical database. Patient's pre- and postoperative hip radiographs were reviewed by the authors. Radiographically detected fracture healing failure (non-union and screw cut-out) was recorded. RESULTS For the period of the study, there were 77 consecutive FNF (76 patients) treated with the dynamic locking plate implant. Eight (10%) patients were lost to follow-up, 13 (17%) patients died within 6 months after surgery. Healing failure was identified in 23 (41%) of remaining 56 cases. Three of four (75% failure rate) failures were observed in cases with fair-quality reduction and two of two (100% failure rate) failures were noticed in the case of none telescoping screw located within subchondral bone. Multiple logistic regression showed an increased risk of fracture failure in cases with at least one completely collapsed telescoping screw (OR = 73.2; 95% CI 9.4-568.5, p < 0.01), while telescoping screws' location around centre of the femoral head reduces the risk of failure (OR = 14.7; 95% CI 1.6-135.1, p = 0.02). CONCLUSION In our group of patients, fracture healing failure of the FNF treated with dynamic locking plate reached 41%. This high failure rate was associated with poor fracture reduction, not subchondrally and centrally placed telescoping screws and in the case of complete collapse on at least one of the telescoping screws.

Abstract
Femoral neck fractures in young patients are uncommon but are often associated with surgical challenges and complications. The quality of reduction, more than time to surgery, has the most impact on optimizing outcomes and function. There is no consensus in the best fixation construct for these fractures. Neck shortening and varus collapse are the most common challenges of current fixation options. Use of newer implants is being reported with cautious optimism, and further studies are needed. LEVEL OF EVIDENCE:: Therapeutic Level V.

Abstract
Fractures of the femoral neck can occur in young healthy individuals due to high loads occurring during motor vehicle accidents, impacts, or falls. Failure forces are lower if impacts occur sideways onto the greater trochanter as compared with vertical loading of the hip. Bone density, bone geometry, and thickness of cortical bone at the femoral neck contribute to its mechanical strength. Femoral neck fractures in young adults require accurate reduction and stable internal fixation. The available techniques for fracture fixation at the femoral neck (cannulated screws, hip screw systems, proximal femur plates, and cephallomedullary nails) are reviewed with respect to their competence to provide biomechanical stability. Mechanically unstable fractures require a load-bearing implant, such as hip screws, with antirotational screws or intramedullary nails. Subcapital or transcervical fracture patterns and noncomminuted fractures enable load sharing and can be securely fixed with cannulated screws or solitary hip screw systems without compromising fixation stability.

Abstract
BACKGROUND We studied the safety and efficacy of dynamic locking plate vs. other implants (cannulated cancellous screws [CCS] or sliding hip screw [SHS]) in patients undergoing intracapsular hip fracture (ICHF). METHODS We searched Pubmed, Embase, Web of Science, Cochrane library and Google database from inception to March 25, 2018. We selected any studies comparing dynamic locking plate for treatment ICHF. Non-union rate, osteonecrosis rate, cutout rate, revision rate, the replacement rate, and Harris hip scores were the outcomes. Stata 12.0 was used for meta-analysis. RESULTS Four studies involving 419 patients (143 patients in the dynamic locking plate group and 276 patients in the other implants group) were finally included. Compared with CCS or SHS, dynamic locking plate was associated with a reduction of nonunion rate, revision rate, replacement rate (P <.05). Furthermore, dynamic locking plate was also associated with an increase of the Harris hip scores (P <.05). There was no significant difference between the osteonecrosis rate and cutout rate (P >.05). CONCLUSIONS Current meta-analysis revealed that dynamic locking plate has a benefit role in improving postoperative clinical outcome than CCS or SHS in ICHF patients. Further high quality and large-scale randomized controlled trials (RCTs) are needed to further identify the efficacy of dynamic locking plate for ICHF.

Abstract
OBJECTIVES Surgical treatment of femoral neck fracture in young adults is clinically challenging due to the high incidence of avascular necrosis of femoral head and fracture nonunion. The objective of this study is to evaluate the effectiveness of cannulated screws with deep circumflex iliac artery bone grafting (DCIABG) by comparing to the routinely used method in the treatment of femoral neck fracture in young adults. METHODS From March 2006 to December 2012, a total of 185 patients with femoral neck fracture were admitted to the hospital for internal fixation surgery, 103 patients (61 males and 42 females, mean age of 39.1 years) were treated with three cannulated screws with DCIABG (group A), and 82 patients (49 males and 33 females, mean age of 35.5 years) were treated with three cannulated screws without DCIABG (group B). RESULTS All patients were followed up for at least 24 months after the surgery. The patients in group A had a significantly higher Harris Hip Score (p < 0.001), shorter fracture healing time (p < 0.001), lower occurrence rate of avascular necrosis of femoral head (p = 0.008) and fracture nonunion (p = 0.012) compared to the patients in group B. However, the operation time and intraoperative blood loss were significantly lower in patients in group B than those in group A (p < 0.001). CONCLUSIONS Cannulated screws with DCIABG significantly reduced femoral head osteonecrosis and fracture nonunion. Therefore, it is a feasible and effective method in the treatment of young adult patients with femoral neck fracture.

Abstract
Aims The objective of this study was to investigate bone healing after internal fixation of displaced femoral neck fractures (FNFs) with the Dynamic Locking Blade Plate (DLBP) in a young patient population treated by various orthopaedic (trauma) surgeons. Patients and Methods We present a multicentre prospective case series with a follow-up of one year. All patients aged ≤ 60 years with a displaced FNF treated with the DLBP between 1st August 2010 and December 2014 were included. Patients with pathological fractures, concomitant fractures of the lower limb, symptomatic arthritis, local infection or inflammation, inadequate local tissue coverage, or any mental or neuromuscular disorder were excluded. Primary outcome measure was failure in fracture healing due to nonunion, avascular necrosis, or implant failure requiring revision surgery. Results In total, 106 consecutive patients (mean age 52 years, range 23 to 60; 46% (49/106) female) were included. The failure rate was 14 of 106 patients (13.2%, 95% confidence interval (CI) 7.1 to 19.9). Avascular necrosis occurred in 11 patients (10.4%), nonunion in six (5.6%), and loss of fixation in two (1.9%). Conclusion The rate of fracture healing after DLBP fixation of displaced femoral neck fracture in young patients is promising and warrants further investigation by a randomized trial to compare the performance against other contemporary methods of fixation.

Abstract
AIM This study compares the outcome of intracapsular hip fracture fixation using the Targon Femoral Neck (TFN) locking plate system with the standard fixation using cannulated cancellous screws (CCS). PATIENTS AND METHOD Analyses of a prospectively collected data of all patients treated for intracapsular hip fractures using the TFN system and CCS at our department over a period of 28 years. Baseline characteristics and specific outcome measures where compared. The primary outcome measure was fracture revision during the 1st year. Secondary outcome measures were fracture complications, any revision surgery, mortality and mobility status at one year after surgery. RESULTS A total of 2004 fractures were included, a third (n=725, 36.2%) were treated using the TFN system. There were higher rates of non-union (19.5% vs 9.5%) and revision surgery (19% vs 9%) during the first year in the CCS cohort. Revision surgery was also higher in the same group during the whole of the follow-up period (22.2% vs 14.9%). The first year's mortality rate was higher in the CCS cohort (21.1% vs 17.5%) but the reduction in mobility and mobility scores was the same in both cohorts. CONCLUSION This study includes the largest cohort of cases treated for intracapsular hip fractures using the TFN system. It demonstrated that the TFN system was associated with lower rates of non-union, revisions and re-operations for any cause.

Prognostic value of dynamic MRI positive enhancement integral color mapping in osteosynthesis of undisplaced femoral neck fractures. J Orthop Sci 2017; 22:722-725.

Abstract
AIMS The common treatment for an undisplaced femoral neck fracture is osteosynthesis. Two major complications of osteosynthesis are non-union and late collapse of the femoral head. We speculated that femoral head perfusion is one of the most important factors that affect the outcome of osteosynthesis after femoral neck fracture. We have preoperatively estimated femoral head perfusion by dynamic MRI positive enhancement integral color mapping (PEICM). The purpose of this study was to evaluate the outcomes of undisplaced femoral neck fractures based on PEICM. PATIENTS AND METHODS Sixty-eight patients participated in this prospective study. All patients underwent PEICM in a 1.5-Tesla MRI machine using coronal fast spoiled gradient echo imaging sequences with gadopentetate dimeglumine as the contrast agent. Femoral head perfusion was displayed via color mapping using PEICM. Three types were distinguished. For type A, the color was identical to unaffected side indicated normal perfusion. For type B, the color was darker than unaffected side indicated decreased perfusion. For type C, the color was black indicated complete absence of perfusion. All patients underwent osteosynthesis with three cannulated screws. The rates of non-union and late collapse for each type were calculated. RESULTS Sixteen patients were classified as Type A, 43 as Type B, and 6 as Type C. The non-union rates were 0% for Type A, 6.7% for Type B, and 50.0% for Type C. The late collapse rates were 0% for Type A, 4.4% for Type B, and 0% for Type C. CONCLUSION PEICM precisely detected femoral head perfusion. Primary prosthetic replacement should be considered for older patients with Type C to minimize the chances of revision surgery, even in undisplaced femoral neck fractures.

Abstract
Currently, there is a lack of effective early screening and detection methods for femoral head necrosis. Current research on most orthopedic diseases focuses on proteomics in the preliminary stage. The recent fluorescence differential in gel electrophoresis (DIGE) has advantages such as a high reproducibility, high sensitivity, high throughput, and high dynamic range. It is currently one of the most widely used quantitative proteomic research means. We conducted this study to investigate the pathogenesis of non-traumatic femoral head necrosis using the fluorescence DIGE to screen non-traumatic femoral head necrosis based on proteomics and provide a theoretical basis for screening possible biomarkers and molecular targeted treatment. The DIGE technique was used to separate the protein. An electrophoretogram was established on the basis of scanning and analysis. Identification and a bioinformatics analysis were conducted for the differential protein. The protein with differential expression of over 2-fold was excavated and ionized by means of substrate assisted laser desorption. The flight time was identified with a mass spectrometer (matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, MALDI-TOF/TOF). The formation on sequences, structures and functions of these proteins were obtained through database retrieval. Western blot analysis was used to verify the differential protein expression and the reliability of the DIGE result was verified. DIGE was used to successfully separate 1,500±40 protein spots. There were 252 significant differential protein spots. The Ettan™ Spot Picker automatic work station was used to excavate 49 significant differential protein spots with expression difference over 2-fold. The MALDI-TOF/TOF mass spectrometer was used to identify these differential protein spots. Six proteins were identified in total, which include apolipoprotein A1 (APOA1), fibrous protein original chain, fibrous protein original chain, serum albumin, sulfur-oxygen protein peroxiredoxin 2 (PRDX2) and actin. APOA1 and PRDX2 were subject to western blot analysis detection; results were consistent with the DIGE result. Based on an analysis of the biological information, these proteins may be associated with the incidence and progression of femoral head necrosis.

Abstract
BACKGROUND It remains unclear whether conservative treatment should be used to treat the common undisplaced femoral neck fractures that develop in the elderly. Herein, we systematically review the rates of union and avascular necrosis after conservative and surgical treatment of undisplaced femoral neck fractures. METHODS We searched the EMBASE, PubMed, OVID, Cochrane Library, Web of Science, and Scopus databases for randomized controlled trials or observational studies that assessed the outcomes of conservative or surgical treatments of undisplaced femoral neck fractures. No language or publication year limitation was imposed. Statistical analyses were performed with the aid of the chi-squared test. We evaluated the quality of each publication and the risk of bias. RESULTS Twenty-nine studies involving 5071 patients were ultimately included; 1120 patients were treated conservatively and 3951 surgically. The union rates were 68.8% (642/933) and 92.6% (635/686) in the former and latter groups, respectively (p < 0.001). The avascular necrosis rate in the conservatively treated group was 10.3% (39/380), while it was 7.7% (159/2074) in the surgically treated group (p = 0.09). CONCLUSIONS Surgery to treat undisplaced femoral neck fractures was associated with a higher union rate and a tendency toward less avascular necrosis than conservative treatment.

Abstract
BACKGROUND The decision between open reduction and internal fixation (ORIF) and arthroplasty for a displaced femoral neck fracture in a patient ≤65 years old can be challenging. Both options have potential drawbacks; if a fracture treated with ORIF fails to heal it may require a revision operation, whereas a relatively young patient who undergoes arthroplasty may need revision within his/her lifetime. The purpose of this study was to employ decision analysis modeling techniques to generate evidence-based treatment recommendations in this clinical scenario. METHODS A Markov decision analytic model was created to simulate outcomes after ORIF, total hip arthroplasty (THA), or hemiarthroplasty in patients who had sustained a displaced femoral neck fracture between the ages of 40 and 65 years. The variables in the model were populated with values from studies with high-level evidence and from national registry data reported in the literature. The model was used to estimate the threshold age above which THA would be the superior strategy. Results were tested using sensitivity analysis and probabilistic statistical analysis. RESULTS THA was found to be a cost-effective option for a displaced femoral neck fracture in an otherwise healthy patient who is >54 years old, a patient with mild comorbidity who is >47 years old, and a patient with multiple comorbidities who is >44 years old. The average clinical outcomes of THA and ORIF were similar for patients 40 to 65 years old, although ORIF had a wider variability in outcomes based on the success or failure of the initial fixation. For all ages and cases, hemiarthroplasty was associated with worse outcomes and higher costs. CONCLUSIONS Compared with ORIF, primary THA can be a cost-effective treatment for displaced femoral neck fractures in patients 45 to 65 years of age, with the age cutoff favoring THA decreasing as the medical comorbidity and risk of ORIF fixation failure increase. Hemiarthroplasty has worse outcomes at higher costs and is not recommended in this age group. LEVEL OF EVIDENCE Economic and decision analysis Level III.

Abstract
The degree of femoral neck collapse that occurred after 519 patients with an intracapsular hip fracture treated by internal fixation with a Targon FN implant was measured. Mean femoral neck collapse was 8.0mm and this was increased for displaced fractures in comparison to undisplaced fractures (9.5mm versus 5.9mm, p<0.0001) and for those patients that subsequently developed fracture healing complications (11.6mm versus 7.1mm, p<0.0001). At one year from injury femoral neck collapse in excess of 15mm was associated with an increase in the degree of residual pain (p=0.01). A clear relationship between increased collapse and increased loss of mobility was demonstrated (P<0.0001). This study confirms previous smaller studies that excessive femoral neck collapse (of more than 15mm) is more common for displaced fractures and presents new data to demonstrate that excessive femoral neck collapse is associated with an increased risk of fracture healing complications and increased loss of function. Future studies are now justified that consider methods to reduce fracture collapse.

Abstract
We report a peri-implant fracture after transtrochanteric rotational osteotomy. Preservation of the nutrient artery of the femoral head is important. The entry point of an anterograde nail would have been very close to the artery. A locking plate is preferable to ante-grade nailing to avoid damaging the artery. The operation resulted in satisfactory results without any complications.
Introduction Transtrochanteric anterior rotational osteotomy of the femoral head (TRO) was developed as a joint preserving surgery for osteonecrosis of the femoral head. To the best of our knowledge, peri-implant fractures after femoral osteotomy have rarely been reported. Presentation of case We report a 58-year-old female who suffered a peri-implant femoral shaft fracture following a fall from a stepladder eight years after TRO. Fracture union was achieved six months after a preferred proximal femoral locking plate. Discussion The entry point of the ante-grade femoral nail would have been very close to the new position of the nutrient artery of the femoral head occasioned by the TRO and to avoid injury, we chose proximal femoral locking plate. Conclusion It is important to consider the new position of the nutrient artery of the femoral head in the surgical planning of peri-implant fracture after TRO.

Abstract
INTRODUCTION At the present time, it is generally recommended to use hip replacement in dislocated fractures to avoid failure after internal fixation. A problem is that previous research has demonstrated that observers have problems in discriminating between dislocated and undislocated fractures. A possible solution to this problem would be to use arthroplasty in the majority of the cases. However, this also means that many fractures with the potential for uneventful healing would be replaced. MATERIALS AND METHODS In the current investigation, the mid-term outcome was recorded for patients with intracapsular hip fractures who were treated with either internal fixation or arthroplasty. A novel treatment algorithm was employed. After careful exclusion of cases with known risk factors for failure after internal fixation, a technique called on-table decision was used to identify suitable patients for internal fixation. RESULTS A total of 72 patients with intracapsular hip fractures were studied with a median follow-up time of 12 months (IQR 8-15.25 months). Nineteen (19) patients (26 %) were excluded in the selection process, leaving 53 (74 %) for on-table decision-making. Thirty patients (42 %) were identified as suitable for internal fixation and gave anatomically stable closed reductions. Two of these patients (7 %) exhibited non-unions and one (3 %) avascular necrosis. CONCLUSIONS The mid-term outcome after internal fixation is promising. The careful selection process may be helpful in identifying fracture patterns for which internal fixation may be considered as a safe and less invasive alternative to hip arthroplasty.

Abstract
OBJECTIVE Operative stabilization is recommended even for non-displaced or only slightly displaced femoral neck fractures. In addition to the known osteosynthetic procedures, an angular stabile implant system (Targon® FN) has been established since 2006 for treatment of such fractures. INDICATIONS Displaced femoral neck fractures (Garden III and IV) and non-displaced fractures (Garden I and II). CONTRAINDICATIONS Fractures close to the hip joint, which are not classified as typical medial femoral neck fractures and patients with advanced osteoarthritis of the hip who would profit from an endoprosthetic procedure. SURGICAL TECHNIQUE The operative procedure is shown after fracture reposition and central positioning of the guide wire as a standard course. POSTOPERATIVE MANAGEMENT Early postoperative mobilization under guidance of a physiotherapist. Initially, partial weight bearing only in selected cases with severe displacement. RESULTS In our patients collective the Targon® FN has been implanted in over 100 cases. Revision indications and secondary endoprosthesis were documented in only 9 % of the cases. This angular stable screw osteosynthesis system is a safe procedure to achieve patient mobility if the indications are adhered to and implantation is correctly carried out.

Abstract
OBJECTIVE The purpose of this study was to present the surgical technique and clinical results of percutaneous compression plate (PCCP) for the treatment of femoral neck fractures. METHODS Between December 2010 and April 2013, 74 consecutive patients with 74 femoral neck fractures were treated by closed reduction and PCCP implants in our university hospital. Their mean age was 51.3 years (range, 15-83 years); 38 (51.4%) were male and 46 (62.2%) of the fractures were on the left. The patients' clinical and radiographic data were analyzed retrospectively. RESULTS There were 45 undisplaced (60.8%) and 29 displaced fractures (39.2%). Eight patients (10.8%) were lost to follow-up. The mean duration of follow-up was 18.8 months for the remaining 66 patients. At the last follow-up, mean Harris hip score was 92.9 (range, 75-100), and 65 patients (98.5%) had excellent and good outcomes. Sixty-five patients (98.5%) were able to walk independently and one (1.5%) with walking-sticks. The mean time to clinical fracture healing was 3.9 months. There were no cases of nonunion. Two patients (3.0%) had delayed union and two (3.0%) developed avascular necrosis, one of 29 (3.7%) with a displaced fracture and one of 45 (2.6%) with an undisplaced fracture. There were no other complications or prosthetic replacement. CONCLUSIONS PCCP is a stable internal fixation device that resists axial and rotational stresses. Our PCCP procedure has a low incidence of nonunion and avascular necrosis.

Abstract
INTRODUCTION Intracapsular hip fractures (ICHF) are a common cause of morbidity and mortality and pose a great economic burden on the health care systems. Appropriate surgical treatment requires balancing optimal outcomes with the cost of treatment to the health care system. While in elderly patients with displaced ICHF arthroplasty became the standard of care, the internal fixation method for conserving the femoral head in younger patients or in nondisplaced ICHF is still in debate. We compared a dynamic locking plate with the standard cancellous cannulated screws (CCS) for treatment of nondisplaced ICHF. METHODS All patients treated with internal fixation for nondisplaced ICHF between July 2009 and December 2012 at our level one trauma center were included in this study. Patients treated with Targon FN (Aesculap) implants and CCS (Synthes) were compared. Charts were reviewed for demographics, intraoperative data and peri/post operative complications retrospectively. Radiographical analysis, pain (VAS), quality of life (SF12) and function (MHHS) data were prospectively gathered. RESULTS One hundred and fifteen non-displaced ICHFs were treated with internal fixation, 81 with CCS and 34 with Targon FN implant; the mean follow-up was 19 and 28 months, respectively. Group fracture characteristics (Garden/Powel classification), and demographics, excluding age, were not significantly different. Post-operative revision rates of the Targon FN and CCS groups, perioperative complications were not statistically different (p>0.05). Quality of life (SF-12), function (Modified Harris Hip Score) and Visual Analogue Scale (VAS) pain scores were not statistical different. CONCLUSIONS Complication rates and clinical outcomes for the treatment of nondisplaced ICHF with Targon FN and SCC showed no significant differences. Based on this evidence in consideration of the substantial cost differential between the Targon FN and SCC we suggest SCC for treatment of nondisplaced ICHF. LEVEL OF EVIDENCE III.

Abstract
The incidence of femoral neck fractures increases exponentially with rising age. Young patients are rarely affected but when they are it is mostly due to high energy accidents, whereas older patients suffer from femoral neck fractures by low energy trauma due to osteoporotic changes of the bone mineral density. Treatment options have not essentially changed over the last few years. Non-operative treatment may be a choice in non-dislocated and impacted fractures. Due to the high risk of secondary fracture displacement prophylactic screw osteosynthesis is recommended even in Garden type I fractures. Osteosynthetic fracture stabilization with cannulated screws or angle stable sliding screws, is usually applied in non-displaced fractures and fractures in younger patients. Older patients need rapid mobilization after surgery; therefore, total hip arthroplasty and hemiarthroplasty are commonly used with a low incidence of secondary complications. In addition to sufficient operative treatment a guideline conform osteoprosis therapy should be initiated for the prophylaxis of further fractures and patients should undertake a suitable rehabilitation.

Abstract
INTRODUCTION The National Institute for Health and Care Excellence (NICE) currently recommends the use of total hip replacement (THR) for displaced intracapsular hip fractures in patients who meet certain mobility, cognitive and health criteria. METHODS A multicentre prospective audit was conducted within a defined geographic region to assess current practice and variation in provision of THR for displaced intracapsular hip fractures. RESULTS A total of 879 patients with hip fractures, admitted to 8 acute trauma units, were included in this study. Of 462 patients with displaced intracapsular hip fractures, 169 fulfilled the NICE criteria for THR. THR was performed for only 49 of (29%) the eligible patients. There was significant variation in THR provision between the eight units (0% to 50% THR usage, p<0.001). There were statistically significant differences in age, ASA (American Society of Anesthesiologists) grade, abbreviated mental test score and walking ability prior to the injury between patients who underwent fixation, THR or hemiarthroplasty (all p≤0.05). There was a significantly increased chance of not undergoing THR if a patient was older than 77 years (median age for the THR eligible cohort; relative risk [RR]: 7.9, 95% confidence interval [CI]: 2.8-22.0, p<0.001). There was also a trend for this with patients who were ASA grade 3 compared with ASA grade 1 or 2 (RR: 2.7, 95% CI: 1.0-7.3, p=0.06). The surgeons gave multifactorial reasons for not performing THR in eligible patients. CONCLUSIONS There is significant variation in the provision of THR for eligible hip fracture patients, which is influenced by both patient demographics and the unit to which a patient is admitted.

Abstract
Optimizing stability of femoral neck fracture fixation is important in obtaining a successful outcome. The mechanical problems and strategies for achieving optimal stability differ depending on patients' age and degree of osteoporosis. Femoral neck fractures in younger adults usually result from high-energy trauma and have a vertical fracture pattern. Strategies for optimizing fixation stability in this group include placing additional screws at right angles to the fracture plane and medial buttress plate augmentation. In elderly patients, screw position relative to the intact cortical femoral neck bone is of critical importance. Additional strategies for optimizing fixation stability in this group include the concept of length stable fixation, use of adjunctive calcium phosphate cement, and use of novel fixed angle fixation implants.

Abstract
A total of 56 male patients with a displaced intracapsular fracture of the hip and a mean age of 81 years (62 to 94), were randomised to be treated with either a cemented hemiarthroplasty (the Exeter Trauma Stem) or reduction and internal fixation using the Targon Femoral Plate. All surviving patients were reviewed one year after the injury, at which time restoration of function and pain in the hip was assessed. There was no statistically significant difference in mortality between the two groups (7/26; 26.9% for hemiarthroplasty vs 10/30; 33.3% for internal fixation). No patient treated with a hemiarthroplasty required further surgery, but eight patients treated by internal fixation did (p = 0.005), five requiring hemiarthroplasty and three requiring total hip arthroplasty. Those treated by internal fixation had significantly more pain (p = 0.02). The restoration of mobility and independence were similar in the two groups. These results indicate that cemented hemiarthroplasty gives better results than internal fixation in elderly men with a displaced intracapsular fracture of the hip.

Abstract
BACKGROUND This study compared the rates of mortality, medical complication, and reoperation after fixation surgery for displaced femoral neck fracture with those after hemiarthroplasty surgery for undisplaced femoral neck fracture using competing risk analysis in inpatients aged 60 years and above from a population database in Taiwan. METHODS We identified 13,772 subjects who underwent fixation for undisplaced cervical fracture and 13,772 matched controls who underwent hemiarthroplasty for displaced cervical fracture from 1998 to 2007, and followed them up until the end of 2009. The outcomes of patients who received internal fixation for undisplaced fracture and those of patients who received hemiarthroplasty for displaced fracture were compared. RESULTS The 3-month, 2-year, and 10-year mortality rates were 4.9%, 22.1%, and 67.1% for fixation, and 5.6%, 23.8%, and 71.0% for hemiarthroplasty, respectively. The 3-month, 2-year, and 10-year cumulative incidence rates of the first reoperation were 7.4%, 18.1%, and 27.7% for fixation and 6.3%, 12.0%, and 22.3% for hemiarthroplasty, respectively. The 3-month cumulative incidence rates of the first medical complication were 14.4% for fixation and 15.4% for hemiarthroplasty, respectively. Hemiarthroplasty had a 1.09 times (95% CI: 1.05-1.12) higher hazard ratio for overall death than fixation. However, fixation had a 1.36 times (95% CI: 1.29-1.43) higher subdistribution hazard ratio for first reoperation than hemiarthroplasty after adjusting for gender, age, and comorbidities. CONCLUSIONS The short-term overall mortality and medical complication rate of fixation for undisplaced fracture were slightly lower than those of hemiarthroplasty for displaced fracture. However, the short-term cumulative incidence of first reoperation after fixation was significantly higher than that for hemiarthroplasty. Further prospective studies or clinical trials based on the competing risk model, and which include important risk factors, are necessary to quantify the adjusted effects more precisely.

Abstract
BACKGROUND In this work, we present relatively long-term results of femoral head fractures with a specific focus on Pipkin type I fractures. METHODS Fifty-nine femoral head fractures were treated according to modified Pipkin's classification as follows: type I, small fragment distal to the fovea centralis (FC); type II, large fragment distal to the FC; type III, large fragment proximal to the FC; type IV, comminuted fracture. There were 15 cases of type I, 28 of type II, 9 of type III, and 7 of type IV fractures. Conservative treatment with skeletal traction was performed in 4 type II cases, excision of the fragment in 15 type I and 10 type II cases, fixation of the fragment in 14 type II and all 9 type III cases, and total hip replacement in all 7 type IV cases. The overall clinical and radiographic outcomes were evaluated using previously published criteria, focusing on the results in Pipkin type I fractures with relatively large fragments. RESULTS Based on Epstein criteria, in type II fractures, excellent or good clinical results were seen in 6 of 10 patients (60.0 %) treated by excision of the fragment and 12 of 14 patients (85.7 %) treated by internal fixation (p = 0.05). Also, excellent or good radiologic results were seen in 4 of 10 (40.0 %) patients treated by excision of the fragment and 12 of 14 (85.7 %) patients treated by internal fixation (p = 0.03). CONCLUSIONS Even in Pipkin type I fractures, if the fragment is large (modified Pipkin type II), early reduction and internal fixation can produce good results.

Abstract
Intracapsular femoral neck fractures are common in the elderly population after a simple fall. However, femoral neck fractures in the physiologically young are less common. Regardless, femoral neck fractures can be a source of significant morbidity and mortality if not treated correctly. Multiple management strategies have been described. The decision for the ideal treatment involves careful consideration of the patient's age, activity, and medical comorbidities. Plating techniques of femoral neck fractures continue to evolve. The authors describe the current indications and plating options for the treatment of femoral neck fractures.

Abstract
Background The Targon FN implant was developed in 2007 to treat intracapsular neck of femur fractures. Early results from the design centre have shown good results in terms of fracture complications. We wished to see if these results can be reproduced in an independent institution. Methods The records of consecutive patients, treated with this implant between 2008 and 2011 at Queen Elizabeth Hospital, were identified and collected for this study. Operations were performed by all grades of surgeons under supervision as appropriate. These patients went on to have both clinical and radiological assessment for fracture healing and function. Results Fifty-one patients were identified with 43 patients available for final follow-up. The average age was 66 years with a minimum follow-up of 24 months. A non-union rate of 0% in the undisplaced fracture group and 1 in 12 (8%) in the displaced fracture group was observed. An avascular necrosis rate of 6% and 8% was observed for undisplaced and displaced fracture types, respectively. No significant change in premorbid to postoperative ambulation was observed and there was no wound complication. Conclusions Our study shows similar results with those of the design centre and which are superior to those currently found in the literature for the more traditional fixation methods. It also shows that the promising results with this new implant as seen from the design institutions can be reproduced by all cadres of surgeons in non-specialist practice.

Abstract
Femoral neck fractures are a commonly encountered injury in orthopaedic practice and result in significant morbidity and mortality. It is essential that surgeons are able to recognize specific fracture patterns and patient characteristics that indicate the use of particular implants and methods to effectively manage these injuries. Use of the Garden and Pauwels classification systems has remained the practical mainstay of femoral neck fracture characterization that help dictate appropriate treatment. Operative options include in situ fixation, closed or open reduction and internal fixation, hemiarthroplasty, and total hip arthroplasty. Recent reports demonstrate diversity among orthopaedic surgeons in regard to the optimal treatment of femoral neck fractures and changing trends in management. The present discussion focuses on the current indications and methods for femoral neck fracture management to provide direction with respect to appropriate and effective care of these injuries.

Abstract
We compared a new fixation system, the Targon Femoral Neck (TFN) hip screw, with the current standard treatment of cannulated screw fixation. This was a single-centre, participant-blinded, randomised controlled trial. Patients aged 65 years and over with either a displaced or undisplaced intracapsular fracture of the hip were eligible. The primary outcome was the risk of revision surgery within one year of fixation. A total of 174 participants were included in the trial. The absolute reduction in risk of revision was of 4.7% (95% CI 14.2 to 22.5) in favour of the TFN hip screw (chi-squared test, p = 0.741), which was less than the pre-specified level of minimum clinically important difference. There were no significant differences in any of the secondary outcome measures. We found no evidence of a clinical difference in the risk of revision surgery between the TFN hip screw and cannulated screw fixation for patients with an intracapsular fracture of the hip.
