Patients older than 55 years presenting with acetabular fractures fulfilling the criteria for acute total hip arthroplasty (THA) were included. Cementless THA was done using the Octopus System and autologous bone grafting. 15 patients were available for latest follow up. The average follow-up was 81.5 months (62–122 months). Mean Harris Hip Score was 91.1. 10 patients were walking without any support while 5 were using a cane. There were no cases of acetabular or femoral component loosening. This method of treatment is promising in the older population as there is deficiency of bone stock which may lead to fixation failures. It is, therefore, worthwhile to recommend primary THA using the Octopus system in the successful management of selected types of acetabular fractures in the elderly.
