摘　　要：目的比较压配型假体和填充型假体对股骨前倾角的影响。方法对64例髋关节置换患者进行前瞻性临床对照研究,其中,32例患者使用强生Tri-lock假体(压配型);32例患者使用强生Summit假体(填充型)。术前及术后分别行CT扫描,计算患者术前自身股骨颈前倾角及术后股骨假体前倾角。分别比较两组患者术前前倾角、术后股骨假体前倾角以及术前、术后前倾角的差值。从而比较不同假体对股骨前倾角的影响。结果所有患者术后股骨假体前倾角均比术前股骨前倾角增大,差异有统计学意义(P<0.01);Tri-lock组与Summit组比较,术后股骨假体前倾角差异无统计学意义(P>0.05)。结论生物固定型股骨假体,无论是填充型还是压配型,其调整股骨前倾角的能力无显著性差异。术后的股骨假体前倾角比术前患者自身的前倾角增大。Objective To explore the influence of Tri-lock and Summit prosthesis on femoral anteversion angle. Methods A comparative prospective study was performed on 64 patients with total hip arthroplasty（ THA）,32 cases with Tri-lock prosthesis and other 32 cases with Summit prosthesis. CT images were used to calculate the preoperative autologous femoral anteversion angles and postoperative femoral-prosthesis angles,and they were compared between the two groups. Meanwhile,the anteversion angles between preoperative CT image and postoperative image were also compared in each case. Results Postoperative femoral-prosthesis angle increased when compared with preoperative autologous femoral anteversion angle in all cases（ P〈0. 01）. While,there were no statistical differences of the femoral-prosthesis angles between Tri-lock group and Summit group（ P〉0. 05）. Conclusion Tri-lock and Summit prosthesis have the equivalent effect on the adjustment of femoral angle in THA.
