Abstract

Three-dimensional assessments of unilateral developmental dysplasia of the hip (DDH) have not been performed yet. Using computed tomography scanning, this study aimed to determine the morphological and rotational abnormalities of the innominate bone in female patients with unilateral DDH. Patients with unilateral and bilateral DDH were compared with healthy patients. The distances between two points along each anatomical part of the pelvis and femur in the coronal plane were measured. The angles of each measurement line for the anterior pelvic plane (APP) and its perpendicular axis were investigated in the sagittal and horizontal planes. The distance between the acetabular centre and anterior inferior iliac spine was longer on both sides in the unilateral DDH group than in the bilateral DDH group. Values of several angles measured on the APP in the horizontal or sagittal plane differed between the unilateral DDH and bilateral healthy groups. The distance between the centres of the femoral head was longer in the unilateral DDH group than in the bilateral healthy group. The distance between the femoral head and middle of the pelvis was longer on the affected side than on the unaffected side in the unilateral DDH group. The iliac bone morphology was similar in both unilateral DDH and bilateral healthy groups; the rotation of the innominate bone was comparable to that in bilateral DDH. The femoral head on the affected side was shifted more laterally than that on the unaffected side in unilateral DDH.

评估单侧髋关节发育不良患者的髂骨形态和髂骨旋转。
目前尚未对单侧髋关节发育不良(DDH)进行三维评估。本研究旨在通过计算机断层扫描确定单侧 DDH 女性患者髂骨的形态和旋转异常。单侧和双侧 DDH 患者与健康患者进行了比较。研究人员测量了骨盆和股骨每个解剖部位两点之间在冠状面上的距离。在矢状面和水平面上,研究了骨盆前平面(APP)的每条测量线与其垂直轴的角度。与双侧DDH组相比,单侧DDH组两侧髋臼中心与髂前下棘之间的距离更长。单侧DDH组和双侧健康组在水平面或矢状面上测量的APP上的几个角度值不同。单侧DDH组的股骨头中心间距长于双侧健康组。单侧DDH组患侧股骨头与骨盆中部之间的距离长于未患侧。单侧DDH组和双侧健康组的髂骨形态相似;髂骨的旋转与双侧DDH组相当。单侧DDH患侧的股骨头比未受影响侧的股骨头更偏向外侧。
