The paper presents the early results of surgical treatment of osteoarthritis secondary to hip dysplasia with CDH hip prosthesis. Between 2001 and 2002 fourteen cases of hip arthritis secondary to dysplasia were treated with CDH prosthesis. Surgery was performed in women, age ranging from 22 to 52 years (average age: 40 years). In 8 cases a cementless CDH femoral component was used. In all cases cementless Taperloc (Biomet) acetabulum components were used. Weight-bearing was allowed 7-14 days post-op. Final patient assessment was done 6-26 months post-op, using the Merle d'Aubigne classification. Patient satisfaction was also taken into account. Functional assessment using this classification yielded 7 points (range: 5-9 points) pre-op, and 11 points post-op (range: 10-12 points). In the post-op assessment, patients reported less pain and an increased range of motion of the hip. No infections were noted. In 1 case deep rein irritation was noted on the second day post-op. In 10 cases there was no limb length discrepancy post-op, while in 4 cases it ranged from 1.5 cm to 3.0 cm. CDH prosthesis allows secure hip replacement procedure, especially in cases with narrow femoral canals.
