髋臼外展角顶区与髋臼横韧带引导髋臼杯植入的效果观察

Top region of acetabular abduction angle and transverse acetabular ligament as reference signs for acetabular implantation

目的观察髋臼外展角顶区与髋臼横韧带引导髋臼杯植入的效果。方法全髋关节置换患者35例,以髋臼横韧带为参照标志确定髋臼杯的前倾角,髋臼杯的外展角是以髋臼外展角顶区和髋臼横韧带为参照标志确定髋臼杯的外展角完成髋臼杯植入。术后测量髋臼杯的外展角和前倾角,观察关节脱位及其它并发症,其末次随访时的髋关节功能评分。结果 Harris 35例均获随访12~23个月,平均(13.0±3.2)个月。术后髋臼杯外展角为(40.11±5.02)°,前倾角为(29.51±7.94)°。1例术后第1天出现髋关节脱位。无深部感染、术后假体周围骨折、髋臼和股骨假体无菌性松动等情况出现。术后末次随访髋关节功能Harris评分优良率为94.3%。结论髋臼外展角顶区与髋臼横韧带可作为髋臼杯植入的可靠参照标志。

Objective To explore the effect of top region of acetabular abduction angle and transverse acetabular ligament（TAL） as reference signs for acetabular implantation. For 35 patients who underwent total hip arthroplasty, the Methodsacetabular abduction angle was positioned with the top region of acetabular abduction angle and transverse acetabular ligament as reference signs, and the acetabular implantation was thus completed. After the operation, the acetabular abduction angle and anteversion angle were measured, joint dislocation and other complications were observed, and the hip function was assessed by Harris scale at the last follow-up. Results All patients were followed up for 12-23 months, a mean duration of（13.0±3.2） months. After the operation, the mean acetabular abduction angle was（40.11±5.02）° and the anteversion anglewas（29.51±7.94）°. 1 case had dislocation of hip joint on Day 1 after the operation. There was no deep infection, periprosthetic fracture and aseptic loosening of acetabula and femoral prosthesis. Harris scale of hip function at the last follow-up had good rate of 94.3%. Conclusion The top region of acetabular abduction angle and transverse acetabular ligament can be used as reliable reference signs for the acetabular implantation.
