USING TRABECULAR METAL AUGMENTS FOR TOTAL HIP REPLACEMENT IN PATIENTS AFTER ACETABULAR FRACTURES

Abstract

The authors presented the experience of treatment of two patients with hip arthritis after acetabular fracture. Both patients were treated with total hip replacement. During the operation, to manage posterior-superior bone defects of the acetabulum, augments of trabecular metal were used. Pain and limitation of motions in hip were indications for operative treatment. After a year of follow up there was no pain in hip; also recovery of motion and improved quality of life were observed.
