Failures with the Judet noncemented total hip.

Primary failures with 36 noncemented Judet total hip arthroplasties are reported. Steep-cup inclination in 7 cases resulted in two dislocations, two migrations, one skew insertion, and two painful hips. Moreover, two migrations were encountered in patients with rheumatoid arthritis. Femoral shaft fractures occurred intraoperatively in 7 cases and postoperatively in another 2 cases. In addition, major fractures of the greater trochanter occurred in 3 cases. The reoperation rate was 11/36, due to primary failures 8-37 months postoperatively. Consequently, the Judet design cannot be recommended for noncemented use.
