This study study was conducted on 20 patients undergoing total hip replacements due to various hip pathologies in adults aged from 20 to 55 years . All patients who had undergone noncemented THR using 36-mm ceramic femoral heads and highly cross-linked polyethylene liners were identified . Indications for use of a ceramic femoral head were young (aged 55 years or younger) and/or active patients. The study excluded any patient with any dislocations, acetabular fractures, infections, or any revision or reoperation as indications for hip joint replacement. All the patients of the study were subjected to the following after an informed consent 1) Full history taking. 2) Clinical assessment , To correlate radiographic readings with patient satisfaction and clinical symptoms, the patients answered a questionnaire, concerning pain and patient satisfaction according to Harris hip score. 3) Radiographic assessment. Duration of the study was 18 months, Preoperative clinical assessment and harris hip score and radiological evaluation and the same protocol for each visit post operatively The results showed that The Harris Hip Score increased from a preoperative mean of 38.2 points to 94.2 points.And range of motion improved from mean 122.35 to 204.15? after 18 months follow-up. These values are higher than those of two other comparable running studies with 28 mm femoral head. Increasing the femoral head size increase the stability and range of motion of the hip joint in THA but with convensional bearing surfaces this cause increased wear rate and decrease the longivity of the prothesis. With new articulatig bearing surfaces as ceramic on highly cross linked poly ethylene we can get the benefit of increasing the head size and increase the longivity of the joint prothesis specially in young adults.
