Are short femoral nails superior to the sliding hip screw? A meta-analysis of 24 studies involving 3,279 fractures.

ABSTRACT: The purpose of this meta-analysis was to compare the fixation outcome between the sliding hip screw (SHS) and intramedullary nails (IMN) in stable and unstable extracapsular proximal femoral fractures. All randomised controlled studies comparing IMNs with a SHS were considered for inclusion. Data was independently extracted and trial methodology assessed. Twenty-four randomised trials involving 3,202 patients with 3,279 fractures were included. Pooled results gave no statistically significant difference in the cut-out rate between the IMN and SHS (41/1,556 vs 37/1,626; relative risk 1.19; 95% confidence interval 0.78-1.82). Total failure rate (1,03/1,495 and 58/1,565, relative risk 1.83; 95% confidence interval 1.35-2.50) and re-operation rate (57/1,357 and 35/1,415, relative risk 1.63; 95% confidence interval 1.11-2.40) were greater with the IMN compared with the SHS. There was no evidence for a reduced failure rate with IMN in unstable trochanteric fractures.

Project description:BackgroundThe aim of this meta-analysis was to evaluate the advantages and disadvantages of proximal femoral nail anti-rotation (PFNA) versus dynamic hip screw (DHS) for the treatment of unstable intertrochanteric fractures, including the available evidence drawn from the literature.MethodsA systematic search was conducted to identify available and relevant randomized controlled trials and retrospective comparative observational studies regarding PFNA compared against DHS in treating unstable femoral intertrochanteric fractures in Embase, PubMed, Cochrane Library, Web of Science, and Scopus Online up to February 12, 2022. Data from the included studies were extracted independently by 2 reviewers and analyzed using RevMan 5.3, and the quality of the studies was assessed.ResultsFive randomized controlled trials and 12 observational studies were recruited and met the inclusion criteria, which consisted of 1332 patients with PFNA and 1271 patients with DHS. The results of the meta-analysis showed that, compared with the DHS, PFNA exhibited a beneficial role in postoperative Harris Hip Scores, operation time, intraoperative blood loss, length of hospital stay, fracture healing time and full weight-bearing time, limb shortening, cutout, reoperation, union problems, the varus collapse of the femoral head/neck, and infection; however, DHS was superior to PFNA in hidden blood loss (relative risk [RR] = 139.81, 95% confidence interval [CI] [136.18, 143.43], P < .00001), postoperation drainage (RR = -17.85, 95% CI [-30.10, -5.60], P = .004), total blood loss (RR = 50.34, 95% CI [42.99, 57.69], P < .00001), and femoral shaft fracture (RR = 4.72, 95% CI [1.15, 19.32], P = .03) treated by DHS were significantly decreased, compared with those by PFNA; however, no significant differences were observed in tip-apex distance, fixation failures, screw migration, or other complicants between the 2 surgical methods.ConclusionAnalysis of a large number of relevant clinical indicators available shows that PFNA has better clinical manifestation than DHS in treating unstable femoral intertrochanteric fractures.

Project description:INTRODUCTION:Sliding hip screw fixation is well established in the treatment of trochanteric fractures of the hip. The X-Bolt Dynamic Hip Plating System builds on the successful design features of the sliding hip screw but differs in the nature of the fixation in the femoral head. A randomised pilot study suggested that the X-bolt Dynamic Hip Plating System might provide similar health-related quality of life while reducing the risk of revision surgery when compared with the sliding hip screw. This is the protocol for a multicentre randomised trial of sliding hip screw versus X-Bolt Dynamic Hip Plating System for patients 60 years and over treated for a trochanteric fracture of the hip. METHODS AND ANALYSIS:Multicentre, multisurgeon, parallel, two-arm, randomised controlled trial. Patients aged 60 years and older with a trochanteric hip fracture are potentially eligible. Participants will be randomly allocated on a 1:1 basis to either sliding hip screw or X-Bolt Dynamic Hip Plating System. Otherwise, all care will be in accordance with National Institute for Health and Care Excellence guidance. A minimum of 1128 patients will be recruited to obtain 90% power to detect a 0.075-point difference in EuroQol-5D health-related quality of life at 4 months postrandomisation. Secondary outcomes include mortality, residential status, revision surgery and radiographic measures. The treatment effect will be estimated using a two-sided t-test adjusted for age, gender and cognitive impairment based on an intention-to-treat analysis. ETHICS AND DISSEMINATION:National Research Ethics Committee approved this study on 5 February 2016 (16/WM/0001). The study is sponsored by the University of Oxford and funded through an investigator initiated grant by X-Bolt Orthopaedics. A manuscript for a high-impact peer-reviewed journal will be prepared, and the results will be disseminated to patients through local mechanisms at participating centres.

Project description:ObjectiveTo investigate the effects of postoperative femoral neck shortening in patients with femoral neck fractures fixed with femoral neck system screws (FNS) and to explore the factors influencing femoral neck shortening.MethodTo retrospectively analyze the data of 113 patients with femoral neck fractures admitted to the Second Hospital of Fuzhou City, affiliated with Xiamen University, between December 2019 and January 2022. Of these, 87 patients were followed up for more than 12 months, 49 men and 38 women: 36 cases of Garden I and II fractures and 51 cases of Garden III and IV fractures, to record the patient's hip Harris score at 12 months postoperatively. Patients were divided into femoral neck shortening group and femoral neck no shortening group according to their regular postoperative follow-up radiographic measurements. To count the incidence of femoral neck shortening, a comparison of postoperative complication rates and hip Harris scores between the two groups was made. Statistical comparison of the two groups and a multifactorial logistic regression analysis were also performed to analyze the factors affecting femoral neck shortening.ResultsAll 87 patients were followed up for more than 12 months after surgery. In 34 of these cases, neck shortening occurred, and the incidence rate was 39.1%. 15 cases of severe shortening, incidence of 17.2%; fracture healing 84 cases, fracture healing rate of 96.5%. The hip Harris score was 83.99 (81.95, 89.20) in the neck shortening group at 12 months postoperatively, 90.87 (87.95, 94.80) for the group without neck shortening; the difference between the two groups was statistically significant (P < 0.01). 32 cases of fracture healing in the neck shortening group at 12 months after surgery, fracture healing rate of 94.1%; 52 cases healed without neck shortening group, fracture healing rate of 98.1%. The difference between the two groups was not statistically significant (P = 0.337). High incidence of neck shortening after FNS fixation of femoral neck fractures, cortical comminution of the severed end, fracture fractionation and quality of reduction were significantly correlated with neck shortening.ConclusionHigh incidence of postoperative neck shortening after internal fixation of femoral neck fractures with the femoral neck system, the cortical comminution, the type of fracture, and the quality of fracture reduction are the influencing factors; femoral neck shortening can affect postoperative hip function, but does not affect fracture healing.
