Traumatic dislocation of the hip is associated with considerable morbidity due to the risk of aseptic necrosis and post-injury arthritis, which is greater in the presence of an associated fracture. Computed tomography after a traumatic dislocation may reveal loose bone fragments within the weight-bearing area of the joint. We advocate the early arthroscopic retrieval of loose bone fragments to preserve the articular surface, as the retention of such fragments may lead to a less satisfactory long-term result. Arthroscopic surgery is associated with less morbidity than open arthrotomy.
创伤性髋关节脱位因存在无菌性坏死和伤后关节炎的风险而伴有相当高的发病率，在伴有骨折时这种风险更高。创伤性脱位后进行计算机断层扫描可能会发现关节承重区域内有游离骨碎片。我们主张早期通过关节镜取出游离骨碎片以保留关节面，因为保留这些碎片可能导致长期效果欠佳。与开放性关节切开术相比，关节镜手术的发病率更低。
