[Luxation of the prothesis after total hip arthroplasty]

In this report we evaluated the incidence of complications following the total hip arthroplasty. We have focused on the role of the surgical approach as thepatient cause of the luxation of the prosthesis. Retrospective analysis of 393 endoprosthetic surgeries performed in the Department of Orthopedics and Traumatology, Pomeranian Medical University, between April 2002 and December 2003 was conducted. Out of 9 patients with prosthesis luxation 6 patients were operated using the posterior approach. A comparative analysis of selected groups did not reveal any significant differences in clinical condition of the patient, the implantation technique or the type of the applied prosthesis. We suggest that the main cause of prosthesis luxation were mistakes that led to misaligment of the prosthetic elements, and the posterior approach was believed to be the the predisposing factor.
