RECONSTRUCTION OF THE DEFICIENT ACETABULUM WITH AN OBLONG PROSTHESIS - 3-YEAR TO 7-YEAR RESULTS

A retrospective review was conducted to determine the intermediate-ter m results of a noncustomized, oblong, porous-coated, cementless, aceta bular component designed to obtain stability on host bone while mainta ining an anatomic hip center. The clinical and radiographic results we re reviewed in 18 patients (3 primary, 15 revision). AU patients had s ubstantial acetabular rim defects before reconstruction with the Johns on and Johnson E-15 or E-25 oblong components. The average follow-up w as 4.5 years (range, 3.4-6.9 years), with an average postoperative Har ris Hip Score of 91 points. Radiographic analysis revealed no prosthet ic migration and near anatomic restoration of the hip center.
