INTRODUCTION The purpose of the present study was to investigate the role of short stem implants for primary total hip arthroplasty in middle-aged patients. For this purpose, a meta-analysis of the current literature was conducted. The focus was on clinical outcomes,radiological parameters, and further complications of both components. MATERIAL AND METHODS The study was performed according to the PRISMA guidelines. All randomized and non-randomized clinical trials comparing short stem versus standard stem prostheses for THA were considered for inclusion. Only studies reporting data concerning uncemented stems for primary total hip arthroplasty were included. Only studies reporting data concerning patients with a mean age of 45 to 69 were included. RESULTS A total of 2197 procedures in 2116 patients were analysed. The mean follow-up was 30.2 months. The short stem group showed a statistically significant higher WOMAC score and a reduced total estimated blood loss compared with the standard stem group. The short stem group showed a reduced rate of femoral fractures, dislocations, and revision, but without statistical significance. CONCLUSIONS According to the main findings of this meta-analysis and current evidence, we encourage the use of the uncemented short stems during primary total hip arthroplasty in middle-aged patients.

中年患者的全髋关节置换术的短茎。

引言本研究的目的是研究短茎植入物在中年患者初次全髋关节置换术中的作用。为此，对当前文献进行了荟萃分析。重点是临床结局，放射学参数以及这两个部分的进一步并发症。材料与方法根据PRISMA指南进行研究。所有比较THA的短茎假体和标准茎假体的随机和非随机临床试验均被认为包括在内。仅包括报告有关初次全髋关节置换术的非骨水泥化茎的数据的研究。仅纳入报告平均年龄为45至69岁患者的数据的研究。结果共分析了2116例患者的2197例手术。平均随访30次。2个月。与标准茎组相比，短茎组显示出统计学上显着更高的WOMAC评分，总估计失血量减少。短茎组显示股骨骨折，脱位和翻修率降低，但无统计学意义。结论根据这项荟萃分析的主要发现和现有证据，我们鼓励中年患者在初次全髋关节置换术中使用无骨水泥短茎。
