UNASSIGNED: Background. The S-ROM-A prosthesis has been designed for the Asian proximal femur with a small deformed shape and narrow canal. In this study, the clinical and radiological results using the S-ROM-A prosthesis for Japanese @entity1 with @entity85 due to @entity1141 and excessive posterior pelvic tilt were examined. Methods. 94 hips were followed up for a mean of 55 months, with a mean age at surgery of 61 years. The primary diagnoses were 94 coxarthritis cases, including 51 @entity1141 and 37 primary OA, 1 avascular @entity39 , 2 @entity625 , and 3 Perthes disease. Thirty-one hips had been treated with @entity572 . Preoperative intramedullary canal shapes were stovepipe in 23 hips, normal in 51 hips, and champagne-flute in 5 hips. The maximum pelvic inclination angle was 56  . Results. The mean JOA score improved from 46 points preoperatively to 80 points at final follow-up. On radiological evaluation of the fixation of the implants according to the Engh classification, 92 (97%) hips were classified as "bone ingrown fixation." Conclusion. In primary THA, using the S-ROM-A prosthesis for Asian @entity1 with proximal @entity85 , even after osteotomy and with posterior pelvic tilt, provided good short- to midterm results.
