Abstract Background This systematic review was conducted to gather available evidence on the effectiveness of muscle pedicle bone flap transplantation in adult patients with femoral neck fractures. Methods Databases such as PubMed, EMBASE, IEEE, Web of Science, and Cochrane library were searched from their dates of inception until March 2021. Two reviewers independently selected the interventional studies on the assessment of the effectiveness of muscle pedicle bone flap transplantation for femoral neck fractures; data extraction and assessment of the methodological quality as per the Institute of Health Economics quality appraisal checklist were also performed by the reviewers. The effectiveness and complication outcomes were assessed by calculating the average rates. Results Overall, 20 studies with 1022 patients were included in this review. Notably, the methodologic quality of the included studies was typically poor. The average effective rates were as follows: good, 73.4%; fair, 15.4%; and poor, 10.9%. Moreover, the average nonunion rate, average avascular necrosis rate, average collapse rate, and the overall reoperation rate were 9.0%, 6.7%, 4.7%, and 7.3%, respectively. Conclusions This systematic review of heterogeneous studies with varying number of patients and varying surgical techniques indicated that muscle pedicle bone flap transplantation provides promising results with low rates of avascular necrosis and nonunion. Nevertheless, further controlled studies are required to ascertain the effectiveness of muscle pedicle bone flap transplantation in treating femoral neck fracture.

Abstract Background Avascular necrosis (AVN) after pediatric femoral neck fracture (PFNF) showed poor prognosis, but its clinical and radiographic characteristics remained unclear. Methods A systematic review and a retrospective study were performed to evaluate the clinical and radiographic characteristics of patients with AVN after PFNF. Results A total of 686 patients with PFNF and 203 patients with AVN from 21 articles were analyzed. Ratliff’s classification was used in 178 patients, with types I, II, and III AVN accounting for 58.4%, 25.3%, and 16.3%, respectively. Ratliff’s assessment was used in 147 patients, of whom 88.4% had an unsatisfactory prognosis. In retrospective study, 115 patients with a mean age of 13.6 ± 2.0 years were included. The mean interval between AVN and PFNF was 13.7 ± 9.5 months. At the time of diagnosis, 59.1% cases were symptomatic and 65.2% progressed to collapsed stage. Fifty (43.5%), 61 (53.0%), and 4 patients (3.5%) were defined as types I, II, and III , respectively, via Ratliff’s classification. Thirteen (11.3%), 40 (34.8%), and 62 patients (53.9%) showed types A/B, C1, and C2 disease, respectively, via the JIC classification. Multivariate analysis demonstrated a strong relation between collapsed stage and symptomatic cases (OR = 6.25, 95% CI = 2.39–16.36) and JIC classification (OR = 3.41, 95% CI = 1.62–7.17). Conclusion AVN after PFNF showed a tendency toward extensive necrotic lesions, presumably resulting in a rapid progression of femoral head collapse. And the symptoms and the JIC classification are other two risk factors of collapse progression.

Introduction. Femoral neck fractures in children and adolescents are rare. However, their complications are frequent - avascular necrosis, femoral neck pseudoarthrosis, premature physeal closure with consequent growth disturbance and coxa vara deformity. Case Outline. A 9.5?year?old boy was injured in a car accident, and femoral neck fracture was diagnosed. Prior to admission at our hospital he was surgically treated several times. He was admitted at our hospital eight months following the accident. On the X?ray transcervical pseudoarthrosis of the femoral neck was found, as well as coxa vara deformity and metaphyseal avascular necrosis. He was operated at our hospital; all previously placed ostefixation material was removed, valgus osteotomy of 30 degrees was done as well as additional local osteoplasty using the commercial osteoindactive agent (Osteovit?). Postoperatively, we applied skin traction, bed rest and physical therapy. At the final follow?up, the patient was recovered completely. He is now painless, the legs are of equal length, range of movements in the left hip is full, life activity is normal. The X?ray shows that the femoral neck pseudoarthrosis is fully healed. Conclusion. This case is presented in order to encourage other colleagues to challenge the problematic situation such as this one. Also, we would like to remind them what one should think about and what should be taken into consideration in the primary treatment of femoral neck fractures in children. Valgus femoral osteotomy, as a part of the primary treatment of femoral neck fracture in children (identically as in the adults) can prevent the occurrence of femoral neck pseudoarthrosis.

Background: The metabolic abnormalities that occur secondary to chronic kidney disease (CKD) increase the risk of femoral neck fractures compared to the general population. The purpose of this study is to determine whether impaired renal function is an independent risk factor for complications after surgery for femoral neck fracture. Methods: The ACS-NSQIP database was reviewed for patients who underwent total hip arthroplasty, hemiarthroplasty and open reduction internal fixation (ORIF) for femoral neck fractures between 2007 and 2018. Patients were split into cohorts based on calculated estimated glomerular filtration rate. Demographic information, comorbidities, and 30-day complications were analysed with univariate and multivariate analyses using chi-square, Fischer’s exact and analysis of variance testing. Results: The total number of patients for the study was 163,717. Patients with CKD stage 4 and 5 had an increased rate of any complication (39.1 and 36.7% respectively) compared with higher eGFRs ( p  < 0.001). Similarly, 30-day mortality was increased at 6.0% and 6.7% for both stage 4 and 5 ( p  < 0.001). By multivariate regression, those with CKD Stage 4 and 5 were at increased risk for any complication compared to patients with a normal preoperative eGFR of 90–120 ( p  < 0.001). Conclusions: This study demonstrated that patients with CKD Stage 4 and 5 are at increased risks of all complications, including death, renal, pulmonary and thromboembolic disease. Therefore, these patients should be cared for from a multidisciplinary approach with close attention to postoperative medications and fall prevention to help mitigate the risk of complications in the immediate postoperative period.

Fixation Techniques

The valgus-impacted (VI) 4-part fractures are a subset of fractures of the proximal humerus with a unique anatomic configuration characterized by a relatively lower incidence of avascular necrosis after operative intervention. We systematically reviewed clinical studies assessing the benefits and harms of least possible fixation techniques (LPFT) for this unique fracture type. Such information would be potentially helpful in developing an evidence-based approach in the management of these complex injuries. We performed analytic searches of PubMed, Embase, Web of Science, Google Scholar and the Cochrane Library, restricting it to the years 1991-2014. Included studies had to describe outcomes and complications after primary osteosynthesis with any type of LPFT apart from plate-screws and intramedullary nailing. Eligibility criteria were also included English language, more than 5 cases, minimum follow up of one year and report of clinical outcome using at least one relevant score (Constant, Neer or ASES). Based on 292 database hits we identified 12 eligible studies including 190 four-part valgus impacted fractures in 188 patients. All eligible studies were case series composed of min 8 to max 45 patients per study. The gender distribution was 60% (112) female and 40% (76) male. The average age of the patients at the time of injury was 54.5 years. In 8/12 studies an open reduction was used for fracture fixation using different surgical techniques including KW, cerclage wires, cannulated screws and osteosutures. Closed reduction and percutaneous fixation was used in 4 studies. Mean follow-up time ranged from 24 to 69 months. A good functional outcome (constant score &gt;80) was reported in 9/12 studies. The most common complication was avascular necrosis of the humeral head with an overall incidence of 11% (range, 0-26.3%). Total avascular necrosis (AVN) was found in 15/188 patients (7.9%) and was more common in percutaneous techniques and partial AVN in 6/188 (3.1%) being more common in open techniques. The overall re-operation rate was very low (3.7%). Insufficient study designs cannot provide definite treatment recommendations and quantitative data synthesis of outcome. In general, LPFT for 4-part VI fractures leads to satisfactory outcomes with low incidence of complications. A considerable risk of biases can be attributed to fracture classification, proper radiological control, mean age of patients, mixed types of fixation methods, nonage adjusted clinical scoring and small follow up periods. These factors are discussed in detail. Level of evidence: systematic review of literature (level IV) as most of the studies were level IV.

<p class="abstract"><strong>Background:</strong> The incidence of neck of femur fracture among elderly population is increasing day by day. Femoral neck fracture has always been an unsolved fracture<strong> </strong>as far as treatment and results are concerned. There are different views regarding the optimal method of internal fixation in femoral neck fractures.

Introduction. Smokers and nicotine users have a higher risk of femoral neck fracture non-union and prolonged time to fracture union. The impact of smoking resulting in revision surgery after fixation of femoral neck fractures, however, rarely has been studied. The aim of this retrospective study was to review if cigarette smoking had an influence on re-operation and revision after femoral neck fracture treatment. Methods. Three groups of patients (Group 1: active smokers; Group 2: former smokers; and Group 3: non-smokers) who sustained a femoral neck fracture from January 2012 through August 2018 were included. Outcomes investigated included femoral neck fracture type, operative fixation type, fixation failure, and time interval between initial fixation and revision. Results. A total of 1,452 subjects were identified (Group 1: 165 subjects; Group 2: 507 subjects; and Group 3: 780 subjects). In the male population, Groups 1 and 2 had higher rates of femoral neck fracture than Group 3. Twelve cases required revisions (Group 1: three cases (6%); Group 2: two cases (2%); Group 3: seven cases (4%)), with all but one revision within the first year following initial fixation. Group 1 patients tended to be younger than the other two groups. Conclusion. Smoking has a positive association with the risk of femoral neck fracture amongst active and former male smokers. This study concluded that active smokers have a higher risk of non-union compared with non-smokers or former smokers. Smoking history, especially heavy or long-term, should play a role in deciding which fixation construct type to use for femoral neck fractures.

Intracapsular Femoral Neck Fracture

Introduction Internal fixation of undisplaced intracapsular femoral neck fractures with cannulated hip screws is a widely accepted surgical technique, despite reported failure rates of 12%–19%. This study determined whether preoperative serum albumin levels are linked to fixation failure. Methods We retrospectively reviewed 251 consecutive undisplaced intracapsular femoral neck fracture patients treated with cannulated hip screws in a district general hospital. Preoperative albumin levels were measured, and the fixation technique, classification and posterior tilt on radiography assessed. Fixation failure was defined as a screw cut, avascular necrosis (AVN) or non-union. Results Of the patients, 185 were female and 66 male. The mean age was 77 years (range 60–101 years). Thirty seven (15%) patients had fixation failure: 10 (4%) due to AVN; 12 (5%) due to non-union; and 15 (6%) due to fixation collapse. Low serum albumin levels were significantly associated with failure (p=0.01), whereas gender (p=0.56), operated side (p=0.62), age (p=0.34) and screw configuration (p=0.42) were not. A posterior tilt angle greater than 20° on lateral radiography significantly predicted failure (p=0.002). Conclusions Preoperative serum albumin is an independent predictor of cannulated hip screw fixation failure in undisplaced femoral neck fractures. Nutritional status should therefore be considered when deciding between surgical fixation and arthroplasty to avoid the possibility of revision surgery, along with an increased risk of morbidity and mortality.
