Abstract
BACKGROUND
Hemiarthroplasty is the standard treatment for patients with femoral neck fractures (FNFs). Controversy exists over the use of bone cement in hip fractures treated with hemiarthroplasty.
OBJECTIVE
We performed an updated systematic review and meta-analysis to compare cemented and uncemented hemiarthroplasty in patients with femoral neck fractures.
METHODS
A literature review was conducted using Cochrane Library, ScienceDirect, PubMed, Embase, Medline, Web of Science, CNKI, VIP, Wang Fang, and Sino Med databases. Studies comparing cemented with uncemented hemiarthroplasty for FNFs in elderly patients up to June 2022 were included. Data were extracted, meta-analyzed, and pooled as risk ratios (RRs) and weighted mean differences (WMDs) with a 95% confidence interval (95% CI).
RESULTS
Twenty-four RCTs involving 3471 patients (1749 cement; 1722 uncemented) were analyzed. Patients with cemented intervention had better outcomes regarding hip function, pain, and complications. Significant differences were found in terms of HHS at 6 weeks (WMD 12.5; 95% CI 6.0-17.0; P < 0.001), 3 months (WMD 3.3; 95% CI 1.6-5.0; P < 0.001), 4 months (WMD 7.3; 95% CI 3.4-11.2; P < 0.001), and 6 months (WMD 4.6; 95% CI 3.3-5.8; P < 0.001) postoperatively. Patients with cemented hemiarthroplasty had lower rates of pain (RR 0.59; 95% CI 0.39-0.9; P = 0.013), prosthetic fracture (RR 0.24; 95% CI 0.16-0.38; P < 0.001), subsidence/loosening (RR 0.29; 95% CI 0.11-0.78; P = 0.014), revisions (RR 0.59; 95% CI 0.40-0.89; P = 0.012), and pressure ulcers (RR 0.43; 95% CI 0.23-0.82; P = 0.01) at the expense of longer surgery time (WMD 7.87; 95% CI 5.71-10.02; P < 0.001).
CONCLUSION
This meta-analysis demonstrated that patients with cemented hemiarthroplasty had better results in hip function and pain relief and lower complication rates at the expense of prolonged surgery time. Cemented hemiarthroplasty is recommended based on our findings.
