Total Hip Arthroplasty with Tantalum Constructions

Results of acetabular reconstruction with tantalum constructions were analyzed for 56 patients (25 men and 31 women) aged 35 to 70 years. Primary arthroplasty was performed in 30 and revision intervention in 26 patients. In case of primary total hip arthroplasty the following etiologic factors were considered: posttraumatic acetabulum deformity (21 patients), deficit of acetabular walls resulted from dysplasia (4), femoral head protrusion (5). Evaluation of the defect and selection of tantalum construction were made using defect classification by W.G. Paprosky. Results were assessed by Harris scale at terms 3,6 and 12 months after operation and every year thereafter. Excellent, good and satisfactory results were achieved in 96.8% of cases. The most common complication was the dislocation of hip implant head. It developed in 2 patients after revision arthroplasty and in 1 patient after primary total hip arthroplasty.
