Forty hips (39 patients) were submitted to metal-on-metal hip replacement (resurfacing) between 2002 and 2005. Evaluation was provided by clinical examination and X-ray tests. The authors performed clinical evaluations before and after surgery. The specific criterion applied was the D'Aubigné and Postel's classification. X-ray images showed radiolucent lines around the acetabular component on the zones described by DeLee and Charnley and around the femoral component on the zones described by Amstutz et al. The mean age was 54.40 years. The minimum follow-up period was 14 months (range:12 to 51 months). The outcomes of 94.44% of the patients in the study were postoperatively rated as satisfactory. There were 2 cases of aseptic loose and no neck-femoral fractures during the follow-up period. The authors concluded that this technique and implant alternative is satisfactory, with good early outcomes in a mean follow-up time of three years.
