Osteointegration analysis with serial radiography as a predictor of successful cementless bipolar hemiarthroplasty at surabaya orthopaedic and traumatology hospital

Osteointegration is a direct structural relationship between the bone and implant surface, properly osseointegration can function without mobility. We aim to evaluate this process using serial radiological examinations, where characteristics such as sclerosis cortical-periosteal thickening will be investigated. A retrospective analytic-observational study was conducted on 96 patients after cementless bipolar hemiarthroplasty operation from January 2012 2021, examined for standing pelvic or hip anterior-posterior radiographs six weeks, months, year post-procedure at Surabaya Orthopaedic Traumatology Hospital. Two musculoskeletal radiology consultants blindly evaluated sclerosis, femoral stem positioning angulation, thickening, leg length discrepancy. The 24 male subjects (25%) 72 female (75%). Bone significantly appeared in six-month evaluation. There no difference positioning. Cortical-periosteal found medial side according valgus position of began appear 6-month evaluation became more prominent one year. No significant discrepancy found.
