Background

We performed a meta-analysis to compare the efficacy and safety of the femoral neck system (FNS) with cannulated cancellous screws (CCSs) in treating femoral neck fractures (FNFs) in controlled clinical trials.

Methods

Eligible scientific articles published prior to September 2021 were retrieved from the PubMed, Web of Science, Springer, ScienceDirect and Cochrane Library databases. The statistical analysis was performed with RevMan 5.1.

Results

Seven retrospective studies met the inclusion criteria. Meta-analysis showed that there were significant differences in perioperative blood loss, the postoperative Harris score, healing time, fluoroscopy frequency, total complications, femoral head necrosis, femoral neck shortening and screw cutout. No significant differences were found regarding operation time, length of hospital stay or nonunion between the two groups.

Conclusion

Compared with CCSs, the FNS showed better clinical efficacy and fewer complications in treating FNFs. Due to the limited quality and data of the currently available evidence, more high-quality randomized controlled trials are needed.

股骨颈系统与空心松质骨螺钉治疗股骨颈骨折的比较：Meta 分析

背景

我们进行了一项荟萃分析，在对照临床试验中比较了股骨颈系统 (FNS) 与空心松质骨螺钉 (CCS) 在治疗股骨颈骨折 (FNF) 中的疗效和安全性。

方法

从 PubMed、Web of Science、Springer、ScienceDirect 和 Cochrane 图书馆数据库中检索了 2021 年 9 月之前发表的符合条件的科学文章。使用 RevMan 5.1 进行统计分析。

结果

七项回顾性研究符合纳入标准。Meta分析显示，围手术期失血量、术后Harris评分、愈合时间、透视频率、总并发症、股骨头坏死、股骨颈缩短和螺钉切断有显着差异。两组在手术时间、住院时间或骨不连方面无显着差异。

结论

与CCSs相比，FNS在治疗FNFs方面表现出更好的临床疗效和更少的并发症。由于目前可用证据的质量和数据有限，需要更多高质量的随机对照试验。
