髋关节和轴骨之间的运动关系是动态的，可以根据个体解剖变化。已有研究表明，骨盆发生率（骶骨斜率+骨盆倾斜）可作为确定骨盆适应矢状面平衡变化能力的指标。个体骨盆发病率不同，因此可能适应不同的退行性和/或医源性脊柱变化。这是一例报告手术改变腰骨盆脊柱导致慢性后路髋关节周围假体不稳定。本次讨论的重点反映了髋关节和脊柱之间的密切关系，并强调了矢状面平衡和髋臼位之间的作用，特别是在全髋关节置换术中。
The kinematic relationship between the hip and the axial skeleton is dynamic and can be variable based on individual anatomy. It has been shown that pelvic incidence (sacral slope + pelvic tilt) can be used as a proxy to determine the ability of the pelvis to accommodate changes in sagittal balance. Individuals have varied pelvic incidence and thus may adapt differently degenerative and/or iatrrogenic to changes that occur in the axial spine. This is a case report in which surgical changes to the lumbopelvic spine resulted in chronic posterior periprosthetic hip instability. The focus of this discussion reflects the intimate relationship between the hip and spine and highlights the role between sagittal balance and acetabular version, specifically as it pertains to total hip arthroplasty.
