摘要: Background In total hip arthroplasty (THA), short-stem prostheses (SS) were designed to achieve better preservation of proximal femoral bone stock and stability than conventional stem (CS), however these effects are controversial. We aimed perform a systematic review meta-analysis evaluate the effectiveness SS CS in primary THA. Methods Relevant randomized controlled trials (RCTs) involving comparison THA screened using electronic databases PubMed, Embase Web Science. Data analyzed with RevMan 5.3 software program evaluated mean difference (MD), risk ratio (RR) 95% confidence intervals (CIs) by random or fixed-effect models. Results Sixteen RCTs 1,233 patients (1,486 hips) included. Compared CS, incidence thigh pain was significantly reduced Proxima (RR 0.13, CI, 0.03-0.51; P=0.004). Bone mineral density (BMD) neck-preserved [SS (I)] showed less decrease Gruen zone 1 (MD 14.60, 10.67-18.54; P<0.00001) 7 9.72, 5.21-14.23; P<0.0001) CS. However, changes BMD not different between without neck group (II)] group. addition, no significant differences found revision rate, Harris Hip Score (HHS), maximum point motion (MTPM) groups. Conclusions The results this study that compared decreased (I) provided remodeling But rates, HHS, MTPM similar. findings require further verification high-quality RCTs.
