The aims of the present study were to describe the technique of hip arthroscopy for osteochondral loose body removal after posterior hip dislocation and report its preliminary results.
We reported consecutive patients undergoing hip arthroscopy for osteochondral fragment after sustaining fracture-dislocations. Seven patients who sustained traumatic hip dislocation with incarcerated osteochondral were included in this study. All patients had standard AP pelvis x-rays and 3D-CT scans. After closed reduction, all patients underwent hip arthroscopy in which loose bodies were removed and labral pathology debrided.
The mean follow-up was 15.7 months. The average Harris Hip Score was 89.8. No patient developed any of the complications commonly associated with arthrotomy including avascular necrosis, heterotopic ossification, and nerve injury.
Arthroscopic treatment of intra-articular loose bodies after hip fracture-dislocations allows excellent visualization of the joint and facilitated straightforward removal of the fragment.
本研究的目的是描述髋关节镜治疗髋关节后脱位后骨软骨游离体取出的技术，并报告其初步结果。
我们报告了连续接受髋关节镜治疗骨折脱位后骨软骨碎片的患者。本研究纳入了7例创伤性髋关节脱位合并嵌顿性骨软骨的患者。所有患者均进行了标准的骨盆前后位X线片和三维CT扫描。闭合复位后，所有患者均接受髋关节镜检查，取出游离体并清理盂唇病变。
平均随访15.7个月。平均Harris髋关节评分为89.8分。没有患者出现任何与切开手术常见相关的并发症，包括缺血性坏死、异位骨化和神经损伤。
髋关节骨折脱位后关节内游离体的关节镜治疗能很好地观察关节，并便于直接取出碎片。
