A study of structures which obstruct reduction of hip dislocation was performed on 15 hips by magnetic resonance imaging (MRI). Before treatment started, MRI studies were performed on 10 patients, six of whom were treated conservatively, after which further MRI studies helped to establish a concentric reduction. In the other four conservative treatment failed and they were operated on; in them the MRI studies were compared with arthrographic and surgical findings. In all but one of these 10 patients, MRI enabled us to differentiate between an everted and an inverted limbus. In five other patients with unsatisfactory development of the hip following closed reduction, MRI was compared with earlier arthrographic studies. MRI provided accurate anatomical information which would not have been obtained by arthrography. It clearly has great potential in assisting the surgeon to select the appropriate form of treatment.
我们通过磁共振成像（MRI）对15例髋关节脱位复位受阻的结构进行了研究。在开始治疗前，对10例患者进行了MRI检查，其中6例接受了保守治疗，之后进一步的MRI检查有助于实现同心圆复位。另外4例保守治疗失败后接受了手术治疗；对他们的MRI检查结果与关节造影及手术所见进行了比较。在这10例患者中，除1例之外，MRI均使我们能够区分翻转的和内翻的髋臼缘。在另外5例闭合复位后髋关节发育欠佳的患者中，将MRI检查结果与早期的关节造影检查结果进行了比较。MRI提供了准确的解剖学信息，而关节造影无法获得这些信息。显然，MRI在协助外科医生选择合适的治疗方式方面具有巨大潜力。
