A hip flexion contracture (HFC) results in an inability to extend the hip by reducing the ROM of the affected hip. The condition affects one in four patients with above-knee amputations on the amputation side. While HFC in other disorders is known to decrease hip ROM and increase pelvic tilt during gait, its impact on the gait of patients with above-knee amputations remains unexplored. Typically, prosthetists design the socket with a flexion angle matching the HFC, potentially leading to compensations during the posterior stance phase of the gait cycle. To our knowledge, little is known about how or whether these compensations relate to the socket's flexion alignment.

臋窝屈曲对线是否与膝上截肢和髋关节屈曲挛缩个体的步态参数变化有关？


髋关节屈曲挛缩 （HFC） 导致无法通过减少受影响髋关节的 ROM 来伸展髋关节。这种情况影响了四分之一的膝盖以上截肢患者。虽然已知其他疾病中的 HFC 会减少步态期间的髋关节活动度并增加骨盆倾斜，但其对膝上截肢患者步态的影响仍未得到探索。通常，修复师设计的接受腔的屈曲角度与 HFC 相匹配，这可能会导致在步态周期的后站位阶段进行补偿。据我们所知，关于这些补偿如何或是否与窝的屈曲对齐有关知之甚少。
