Imaging observation of percutaneous compression plate use in promoting femoral neck fracture healing.

ABSTRACT:

Objective

To examine the imaging evidence of the use of percutaneous compression plate (PCCP) in promoting femoral neck fracture healing compared with cannulated screws (CS).

Methods

This retrospective study enrolled patients with femoral neck fractures undergoing internal fixation procedures. The patients were divided into a PCCP group and a CS group with imaging as the primary outcome and Harris hip score (HHS) as the secondary outcome.

Results

This study included 162 patients: 80 in the PCCP group and 82 in the CS group. There were no significant differences between the patients in their preoperative baseline characteristics. Patient follow-up ranged from 24-56 months (mean 30.7 months). Differences in reduction quality, screw slipping, neck shortening and avascular necrosis (AVN) were not significant between the two groups. There were significant differences between the treatment groups in bone absorption, nonunion, healing time, screw withdrawal and fixation failure in favour of the PCCP group. Postoperative HHS at 6 and 12 months were significantly better for the PCCP group than the CS group, but the differences were not significant at 24 months and last follow-up.

Conclusion

Stable internal fixation with dynamic compression was the key to PCCP promoting femoral neck fracture healing.

Project description:ObjectiveThis meta-analysis aimed to compare the relative safety and efficacy of cannulated compression screw (CCS) and femoral neck system (FNS) in treating patients with femoral neck fractures and to provide evidence-based medical evidence for FNS in treating femoral neck fractures.MethodsPubMed, Embase, Cochrane, and China National Knowledge Infrastructure databases were searched to collect outcomes related to femoral neck fractures treated with FNS and CCS, including time to fracture healing, incidence of non-union, incidence of osteonecrosis of the femoral head, incidence of failure of internal fixation, rate of femoral neck shortening, Harris hip score, Barthel index, operative time, intraoperative blood loss, fluoroscopy frequency, and complications. A meta-analysis was performed using RevManv5.4 (The Cochrane Collaboration) and Stata v14.0 software.ResultsThis analysis included 21 studies involving 1,347 patients. The results showed that FNS was superior to CCS in terms of fracture healing time [mean difference (MD) = -0.75, 95% CI = (-1.04, -0.46), P < 0.05], incidence of bone non-union [odds ratio (OR) = 0.53, 95% CI = (0.29, 0.98), P = 0.04], incidence of osteonecrosis of the femoral head [OR = 0.49, 95% CI = (0.28, 0.86), P = 0.01], incidence of internal fixation failure [OR = 0.30, 95% CI = (0.18, 0.52), P < 0.05], rate of femoral neck shortening [OR = 0.38, 95% CI = (0.27, 0.54), P > 0.05], Harris hip score [MD = 3.31, 95% CI = (1.99, 4.63), P < 0.001], Barthel index [MD = 4.31, 95% CI = (3.02, 5.61), P < 0.05], intraoperative bleeding [MD = 14.72, 95% CI = (8.52, 20.92), P < 0.05], fluoroscopy frequency [OR = 0.53, 95% CI = (0.29, 0.98), P = 0.04], and complications [OR = 0.31, 95% CI = (0.22, 0.45), P < 0.05]. The difference between FNS and CCS in operative time was not statistically significant [MD = -2.41, 95% CI = (-6.88, 2.05), P = 0.29].ConclusionFNS treatment of femoral neck fracture can shorten the fracture healing time; reduce the incidence and translucent rate of bone non-union, osteonecrosis of the femoral head, and internal fixation failure; reduce intraoperative blood loss and postoperative complications; and improve hip joint function and activity. We are confident in the findings that FNS, an effective and safe procedure for internal fixation of femoral neck fractures, is superior to CCS.

Project description:BackgroundHyperbaric oxygen therapy (HBOT) consists of intermittently administering 100% oxygen at pressures greater than one atmosphere absolute (ATA) in a pressure vessel. This technology has been used to treat a variety of diseases and has been described as helping patients who have delayed healing or established non-union of bony fractures. This is an update of a Cochrane Review first published in 2005, and previously updated in 2008.ObjectivesThe aim of this review is to assess the evidence for the benefit of hyperbaric oxygen treatment (HBOT) for the treatment of delayed bony healing and established non-union of bony fractures.Search methodsWe searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (July 2012), the Cochrane Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 7), MEDLINE (1946 to July Week 1 2012), EMBASE (1974 to 2012 July 16), CINAHL (1937 to 17 July 2012), the Database of Randomised Controlled Trials in Hyperbaric Medicine (accessed July 2012), the WHO International Clinical Trials Registry Platform (17 July 2012) and reference lists of articles.Selection criteriaWe aimed to include all randomised controlled trials comparing the clinical effects of HBOT with no HBOT (no treatment or sham) for healing of bony fractures and fracture non-unions.Data collection and analysisTwo review authors independently screened electronic search results, and all three authors independently performed study selection. We planned independent data collection and risk of bias assessment by two authors using standardised forms.Main resultsNo trials met the inclusion criteria. In this update, we identified three ongoing randomised controlled trials. Among the eight excluded studies were three randomised trials comparing HBOT with no treatment that included patients with fractures. One of these trials had been abandoned and the other two did not report on fracture healing outcomes.Authors' conclusionsThis systematic review failed to locate any relevant clinical evidence to support or refute the effectiveness of HBOT for the management of delayed union or established non-union of bony fractures. Good quality clinical trials are needed to define the role, if any, of HBOT in the treatment of these injuries. There are three randomised controlled trials underway and we anticipate these will help provide some relevant clinical evidence to address this issue in the future.
