Abstract
Patients with substantial skeletal dysplasia and hip arthritis are poor candidates for noncustom total hip arthroplasty (THA) because of hip size and deformity. To determine the efficacy of THA via modified prostheses and surgical techniques in this population, the authors analyzed 9 consecutive THAs in 7 small-stature adults (mean height, 118.6 cm; mean weight, 47.5 kg). The Student t-test was used to test for significant (P < 0.05) differences in outcome variables. Seven hips received custom femoral components based on imaging studies. Five hips required extensive soft-tissue releases secondary to severe contractures. Follow-up radiographs (range, 24-56 months) showed adequate position of all prostheses and no loosening. Follow-up mean pain and function scores (Harris Hip Score and WOMAC Arthritis Index) showed significant improvement from preoperative levels.
