Total hip arthroplasty in patients dialyzed or with renal transplants.

The authors present 15 cases of hyp arthroplasty implanted in patients affected with necrosis of the femoral head, which were undergoing periodic hemodialitic treatment, or with renal transplants. Ceramic-ceramic prostheses were prevalently used and only in 1 case was a metal-polyethylene prosthesis used. Because of precarious mineralization a cemented prosthesis was implanted in dialyzed patients; in renal transplants, instead, cemented or cementless prosthesis were used depending on the state of the bone. There was a high percentage of excellent results after 2-8 years (87%), and this confirms the validity of surgical indications for the use of arthroplasty in hips affected with epiphyseal necrosis in order to favor functional recovery: considering the young age od the patients, this helps them to go back to being a part of society, and to recover psychologically.
