The association between hip and spine abnormalities is frequent, and limitation in hip extension has been linked with low back pain. The purpose of this study was to assess the radiographic osseous findings in nonarthritic hips of patients with hip pain, low back pain, and limited hip extension. Ninety patients (92 hips) were included in this study. Hip extension was tested in the contralateral decubitus position with the hip in neutral abduction/adduction and neutral rotation. In sequence, hip extension was tested by adding passive abduction, followed by internal/external rotation of the hip. A hip extension limitation was defined as less than zero degrees of extension. Imaging studies were assessed for the following osseous morphologies: decreased ischiofemoral space (≤17 mm), increased femoral torsion (≥30°), decreased femoral torsion (≤5°), and posterior acetabular overcoverage. Fifty-seven out of 92 hips (62%) had at least one osseous imaging finding for limitation in hip extension: decreased ischiofemoral space (38/92, 41%), increased femoral torsion (5/92, 5%), decreased femoral torsion (24/92, 26%), and posterior acetabular overcoverage (21/92, 23%). Decreased ischiofemoral space, femoral torsional abnormalities, and/or posterior acetabular wall overcoverage are observed in imaging studies of most individuals with limitation of hip extension and low back pain.
髋部与脊柱异常之间的关联很常见，髋部伸展受限与腰痛有关。本研究的目的是评估髋部疼痛、腰痛且髋部伸展受限患者的非关节炎性髋部的影像学骨质表现。本研究纳入了90例患者（92个髋部）。在对侧卧位下测试髋部伸展，髋部处于中立位外展/内收和中立位旋转。依次通过增加被动外展，然后进行髋部内旋/外旋来测试髋部伸展。髋部伸展受限定义为伸展角度小于零度。对影像学研究评估以下骨质形态：坐骨股骨间隙减小（≤17毫米）、股骨扭转增加（≥30°）、股骨扭转减小（≤5°）以及髋臼后倾覆盖增加。92个髋部中有57个（62%）至少有一项髋部伸展受限的骨质影像学表现：坐骨股骨间隙减小（38/92，41%）、股骨扭转增加（5/92，5%）、股骨扭转减小（24/92，26%）以及髋臼后倾覆盖增加（21/92，23%）。在大多数髋部伸展受限和腰痛患者的影像学研究中观察到坐骨股骨间隙减小、股骨扭转异常和/或髋臼后壁覆盖增加。
