Mechanical hip pain typically has been associated either with dynamic factors resulting in abnormal stress and contact between the femoral head and acetabular rim when the hip is in motion or with static overload stresses related to insufficient congruency between the head and acetabular socket in the axially loaded (standing) position. Compensatory motion may adversely affect the dynamic muscle forces in the pelvic region, leading to further strain and pain. Hip pain related to static overload stresses may also be localized to the anteromedial groin, but compensatory dysfunction of the periarticular musculature may lead to muscular fatigue and associated pain throughout the hip. As our understanding of hip joint mechanics has advanced, it has become increasingly apparent that hip pain in the absence of osteoarthritis may be due to a complex combination of mechanical stresses, both dynamic and static. With an emphasis on findings in the recent literature, this review will describe the dynamic and static factors associated with mechanical hip pain, the combinations of dynamic and static stresses that are commonly identified in hip pain, and common patterns of compensatory injury in patients with femoroacetabular impingement.
运动时股骨头与髋臼缘之间的动态因素导致异常的应力和接触，或者轴向负荷（站立）时头部与髋臼窝之间的静态过载应力导致的不匹配。代偿运动可能会对骨盆区域的动态肌肉力量产生不利影响，导致进一步的紧张和疼痛。与静态过载相关的髋部疼痛也可能局限于前内侧腹股沟区域，但关节周围肌肉的代偿功能障碍可能导致肌肉疲劳和整个髋部相关疼痛。随着我们对髋关节力学的理解的提高，越来越明显的是，在没有骨关节炎的情况下，髋部疼痛可能是由于多种机械应力的复杂组合，包括动态和静态的。本文重点介绍了近期文献中的发现，将描述与机械性髋痛相关的动态和静态因素、髋痛中常见的动态和静态应力组合以及股骨髋臼撞击症患者常见的代偿性损伤模式。
