Early detection of osseointegration can make the clinician know prediction how the successful their operation. The aim of the study was to correlation a partial weight bearing with osseointegration using serial radiological examination where characteristics such as bone sclerosis and cortical-periosteal thickening. This study is a retrospective analytic-observational study conducted at Orthopaedic and Traumatology Surabaya Hospital, entailing 96 patients after cementless bipolar hemiarthroplasty operation from January 2012 to January 2021.
