Early Degradation of Resurfacing Prostheses

Abstract

The resurfacing arthroplasty is a new method, superior techniques used in hip arthroplasty, through the immediate post-operative recovery and distance, followed by a complete reversal of limb function and a minimum rate of postoperative complications. Performance of this prosthesis is evident in well selected cases (young patients with physical activity) after a surgical indication correctly formulated. 39 patients with aseptic necrosis of the femoral head prosthesis underwent surgery with total hip resurfacing type in Clinical Orthopaedics-Traumatology, University Hospital Bucharest between 2005-2009. The diagnosis was established by X-ray and MRI examination. Sex ratio was: 22 men and 17 women. Age groups: 11 patients 20-30 years, 30-40 years 16 patients, 12 patients over 40 years... Approach was developed by postero-lateral joint capsule being maintained to preserve femoral vasculature. Recovery was fast in a short amount of time patients. All patients were reviewed clinically and radiographically at 4 weeks, 6 weeks, 3 months, 6 months, and 12 months, then annually. There were 5 cases of revision after resurfacing arthroplasty type of causes independent of design and composition of these prostheses. Revision surgeries of these prostheses have gone easier than in the case of conventional prostheses. Most times it is enough just replacing the stem, keeping torque meta-metal large head with all its benefits. The importance of this type of arthroplasty is that: are aimed at young people, preserves bone capital, maintain femoral vasculature, rapid, resumption of intense physical activity, complete recovery of movement in the hip joint, lack of formidable complications in hip arthroplasty dislocation represented.
