臀中肌对于步态和髋关节稳定性至关重要。髋关节发育不良（DDH）患者臀中肌发生的变化尚不清楚。更好地了解DDH相关的变化将对髋关节软组织重建产生积极的影响。对19例单侧DDH拟行全髋关节置换术的成人患者进行了评估：横截面积（CSA）、放射学密度（RD）和臀中肌长度，采用计算机断层摄影（CT）（THA前扫描）。通过髋关节前后位X线片测量髋外展肌力臂和臀中肌激活角。患侧臀中肌CSA和RD均较对照组显著降低（p < 0.05）。患侧臀中肌长度缩短8- 11%（p < 0.05），臀中肌激活角增大（p <0.05），髋外展肌力臂减小（p < 0.05）。髋关节发育不良患者的臀中肌CSA、RD明显减少，长度缩短。在DDH患者的髋关节重建和术后康复训练中应考虑这些变化。
The gluteus medius muscle is essential for gait and hip stability. Changes that occur in the gluteus medius muscles in patients with developmental dysplasia of the hip (DDH) are not well understood. A better understanding of DDH related changes will have positive repercussions toward hip soft tissue reconstruction. 19 adult patients with unilateral DDH scheduled for total hip arthroplasty were assessed for: cross-sectional area (CSA), radiological density (RD) and the length of gluteus medius using computed tomograhpy(CT) (scanned before THA). Hip abductor moment arm and gluteus medius activation angle were also measured via hip anteroposterior radiographs. Both CSA and RD of gluteus medius muscle were significantly reduced (p < 0.05) in the affected hip compared to the control. In the affected hip, the length of the gluteus medius muscle was reduced by 8-11 % (p < 0.05) while the gluteus medius activation angle was significantly increased (p < 0.05) and the hip abductor moment arm was decreased (p < 0.05). The gluteus medius showed substantial loss of CSA, RD as well as decreased length in patients with DDH in the affected hip. These changes should be considered in both hip reconstruction and postoperative rehabilitation training in patients with DDH.
