Abstract

Objectives: to evaluate the short-term performance of a type of implant manufactured inBrazil.Methods: this study analyzed a cohort of 60 patients who underwent implantation of MD-4®acetabular components during primary hip arthroplasty procedures performed betweenJanuary 1, 2010, and August 1, 2012. The patients were studied retrospectively with regardto clinical behavior, stability and radiological osseointegration. The patients were followed up for a minimum of 12 months and a maximum of 42 months (mean: 27) and were evaluated by means of the Harris Hip Score, SF-36 questionnaire and serial conventional radiographs. Results: all the components were radiologically stable, without evidence of migration or progressive radiolucency lines. On average, the Harris Hip Score evolved from 36.1 to 92.1 (p < 0.001) and the SF-36 showed significant increases in all its domains (p < 0.001). No differences were observed among patients with osteoarthrosis, osteonecrosis, hip dysplasia or other conditions. Conclusions: the short-term results showed clinical and radiological signs of stability and osseointegration of the implants, which may represent a predictive factor regarding medium-term survival of this acetabular component.
