Abnormal femoral version is a deformity in the angle between the femoral neck and the transcondylar axis of the knee. Both femoral anteversion and retroversion alter passive and active rotation of the hip and are associated with intra-articular or extra-articular impingement. However, little is known about the effect of abnormal femoral version on intra-articular hip contact stresses. To quantify the effect of femoral version on hip contact stress, five cadaveric pelvis specimens were mechanically tested with a hip-specific Tekscan sensor inserted in the joint space. Specimens were oriented in a heel-strike position and loaded with 1000 N of compressive force. Pressure measurements were recorded by the Tekscan sensor with the femur oriented in 0°, 15°, and 30° of version. At the completion of testing, specimens were locked into place at 0° and post-test CT scans were obtained to register the pressure sensor measurements to the joint anatomy. There were minor changes in contact area (<7%) and translation of the peak contact stress location (8.8 ± 7.6 mm). There was no significant change in peak contact stress (p = 0.901) in either the retroverted (0°) or anteverted (30°) conditions relative to normal version (15°) under identical gait-related loading conditions. While abnormalities in patient gait and resultant joint loading caused by femoral version abnormalities may contribute to hip pain, the present findings would suggest that future joint degeneration in hips with version abnormalities are not simply the result of abnormal contact stress induced by joint incongruity due to femoral version abnormalities.

异常股骨版本是股骨颈和膝关节经髁轴之间的角度畸形。股骨前倾和后倾都会改变髋关节的被动和主动旋转，并与关节内或关节外撞击有关。然而，关于异常股骨版本对髋关节内接触应力的影响知之甚少。为了量化股骨版本对髋部接触应力的影响，五个尸体骨盆标本用插入关节空间的髋部特定 Tekscan 传感器进行了机械测试。样本以足跟撞击位置定向并加载 1000 N 的压缩力。压力测量值由 Tekscan 传感器记录，股骨以 0°、15° 和 30° 的角度定向。在测试完成时，标本以 0° 锁定到位，并获得测试后 CT 扫描以将压力传感器测量值记录到关节解剖结构。接触面积 (<7%) 和峰值接触应力位置的平移 (8.8 ± 7.6 mm) 有微小变化。在相同的步态相关负载条件下，相对于正常版本 (15°)，在后倾 (0°) 或前倾 (30°) 条件下，峰值接触应力 (p = 0.901) 没有显着变化。虽然股骨版本异常引起的患者步态异常和由此产生的关节负荷可能导致髋部疼痛，但目前的研究结果表明，未来版本异常的髋关节退化不仅仅是由于股骨不协调引起的异常接触应力的结果。版本异常。
