Background:
There is conflicting evidence as to whether the femoral head should be preserved or replaced in elderly patients with displaced intracapsular femoral neck fractures. In this article, we performed a systematic review and meta-analysis to compare the short- and long-term effectiveness of arthroplasty (AR) and internal fixation (IF).
Methods:
PubMed, Embase, and the Cochrane Library were searched systematically up to January 2016. All randomized controlled trials directly comparing the effectiveness of AR and IF for displaced intracapsular fracture were retrieved with no limitation on language or publication year.
Results:
In total, eight prospective randomized studies involving 2206 patients were included. The results of our study showed that patients in the AR group reported significantly lower complication (risk ratio: 0.56, 95% confidence interval [CI] = 0.38-0.80), re-operation (risk ratio: 0.17, 95% CI = 0.13-0.22), revision rates (risk ratio: 0.11, 95% CI: 0.08-0.16), and better function compared with their IF counterparts, and they were less likely to suffer postoperative pain. No statistically significant differences for the rates of mortality, infection, and/or deep vein thrombosis between AR and IF were found.
Conclusions:
Based on our analysis, we recommend that AR should be used as the primary treatment for displaced intracapsular femoral neck fractures in the elderly. However, IF may be appropriate for those who are very frail.
