Since Offierski and MacNab reported a close association between the hip and spine as hip-spine syndrome in 1983, many studies on spinal alignment in hip disorders have been conducted. Notably, the pelvic incidence angle (PI) is the most important parameter and is determined by the anatomical variations in the sacroiliac joint and hip. Studies on the association of the PI with hip disorders can help in understanding the pathophysiology of hip-spine syndrome. A PI increase has been observed during the evolution of bipedal locomotion in humans and in the acquisition of gait during child development. Although the PI is a fixed parameter that is stable and unaffected by posture from adulthood onwards, it has become clear that it increases in the standing position in older people. While it may be associated with a greater risk of developing or progressing to spinal disorders, the association between the PI and hip disorders remains controversial because of the multifactorial nature of hip osteoarthritis (HOA) and the wide range of PIs in HOA (18-96°), making the interpretation of results difficult. However, several hip disorders (i.e., femoroacetabular impingement and rapid destructive coxarthrosis) have been shown to be associated with the PI. Further investigation on this topic is, therefore, warranted.
自1983年奥菲尔斯基和麦克纳布报道髋关节与脊柱之间存在密切关联，即髋-脊柱综合征以来，已经开展了许多关于髋关节疾病中脊柱排列的研究。值得注意的是，骨盆入射角（PI）是最重要的参数，它由骶髂关节和髋关节的解剖变异决定。对PI与髋关节疾病关联的研究有助于理解髋-脊柱综合征的病理生理学。在人类双足行走的进化过程以及儿童发育过程中步态的习得过程中，都观察到了PI的增加。虽然PI是一个固定参数，从成年起就稳定且不受姿势影响，但很明显，老年人站立时PI会增加。虽然它可能与发生或进展为脊柱疾病的风险增加有关，但由于髋骨关节炎（HOA）的多因素性质以及HOA中PI范围广泛（18°-96°），使得结果难以解释，PI与髋关节疾病之间的关联仍存在争议。然而，一些髋关节疾病（即股骨髋臼撞击症和快速破坏性髋关节炎）已被证明与PI有关。因此，有必要对这一主题进行进一步研究。
