我们的目的是调查影响髋关节表面置换术后屈曲范围的因素。在平均43个月时，对由一名外科医生手术的82例病例进行了评估。髋臼杯软件的Einzel-Bild-Roentgen分析用于测量髋臼窝方向。屈曲范围与髋臼杯前倾呈中度正相关（R = 0.26，P = 0.017），与股骨颈直径呈弱但显著的负相关（R = 0.23，P = 0.042），与股骨头颈前偏移无关。采用多变量分析，调整年龄、性别、髋臼杯前倾和倾斜度、头颈偏心距比、头颈比和颈部直径，屈曲的唯一显著相关性是髋臼杯前倾（P = 0.017）。在放置髋臼杯时应小心，以便在伯明翰髋关节表面置换术中保持足够的前倾，因为这可能影响屈曲活动范围。
We aimed to investigate the factors affecting range of flexion after hip resurfacing. A total of 82 cases, operated by a single surgeon, were assessed at a mean of 43 months. The Einzel-Bild-Roentgen-Analysis for the acetabular cup software was used to measure socket orientation. Range of flexion had a moderate positive correlation with cup anteversion (R = 0.26, P = .017), weak but significant negative correlation with neck diameter (R = 0.23, P = .042), and none with anterior femoral head-neck offset. Using multivariate analysis that adjusted for age, sex, cup anteversion and inclination, head-neck offset ratio, head-neck ratio, and neck diameter, the only significant correlate of flexion was cup anteversion (P = .017). Care should be taken during cup placement to allow adequate anteversion to be maintained in Birmingham hip resurfacing because this can affect flexion range of motion.
