Objective : 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.
Material and Method: 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.
Results : 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.
Conclusion : Arthroscopic treatment of intra-articular loose bodies after hip fracture-dislocations allows
excellent visualization of the joint and facilitated straightforward removal of the fragment.
