本文对86例患者术后至少1年的全髋关节置换术(THA)患者进行了标准的髋关节和骨盆正位X线片及活动度和等长外展力的测量，股骨偏移量与外展范围呈正相关(p=0.046)。外展力量与股骨偏移量(p=0.0001)和外展肌臂长度(p=0.005)呈正相关。通过多元回归分析，外展力与身高(p=0.017)、性别(p=0.0005)、屈曲范围(p=0.047)和外展肌杠杆臂(p=0.060)相关。我们的研究结果表明，全髋关节置换术后股骨偏移量越大，外展范围越大，外展肌力越强。
At a minimum of one year after operation, we studied 64 patients with 86 total hip arthroplasties (THA) by standard anteroposterior hip and pelvic radiographs and measurement of range of motion and of isometric abduction strength.The femoral offset correlated positively with the range of abduction (p=0.046). Abduction strength correlated positively with both femoral offset (p=0.0001) and the length of the abductor lever arm (p=0.005). Using multiple regression, abduction strength correlated,vith height (p=0.017), gender (p=0.0005), range of flexion (p=0.047) and the abductor lever arm (p=0.060).Our findings suggest that greater femoral offset after THA allows both an increased range of abduction and greater abductor strength.
