This study was conducted to compare cemented and cementless bipolar hemiarthroplasty in elderly patients with unstable intertrochanteric fractures via meta-analysis and systematic review of relevant studies.
Systematic review and meta-analysis were performed on 31 available clinical studies; 19 of these studies used cemented stems, 12 used cementless stems, one used both types of stems, and two studies involved a comparative analysis of both stem types.
There were statistically significant differences in rates of leg length discrepancy (LLD) greater than 1 cm between the cemented (event rate, 0.089) and cementless groups (event rate, 0.015 and 0.047; =0.03).
Cemented bipolar hemiarthroplasty and cementless bipolar hemiarthroplasty performed on elderly patients with unstable intertrochanteric fracture revealed similar mortality and complication rates; however, the rate of LLD greater than 1 cm was significantly higher in the cemented group compared with the cementless group.
通过对相关研究的荟萃分析和系统评价，比较骨水泥型和非骨水泥型双极半髋关节置换术治疗老年不稳定型转子间骨折的效果。
对31项现有的临床研究进行系统评价和荟萃分析；其中19项研究使用骨水泥型假体柄，12项使用非骨水泥型假体柄，1项同时使用两种类型的假体柄，2项研究涉及两种假体柄类型的对比分析。
骨水泥型组（事件发生率，0.089）与非骨水泥型组（事件发生率，0.015和0.047；P = 0.03）相比，腿长差异（LLD）大于1 cm的发生率存在统计学显著差异。
骨水泥型双极半髋关节置换术和非骨水泥型双极半髋关节置换术治疗老年不稳定型转子间骨折的死亡率和并发症发生率相似；然而，骨水泥型组腿长差异大于1 cm的发生率显著高于非骨水泥型组。
