Functional and radiological outcomes of impaction grafts and cemented cup for treatment of acetabular bone deficiency in total hip arthroplasty.

Maysara Abdelhalim Bayoumy*, Mohamed Mosa Mohamed

Background: Acetabular bone defects are one of the most difficult problems in both primary and revision Total Hip Replacement (THR). Many techniques have been described to deal with acetabular bone defects in THR, including the use of cement with or without cages and rings, structural bone grafting, and impaction bone grafts with cementless or cemented cups. The aim of this study was to investigate the use of impaction bone grafts to reconstruct the deficient acetabulum with cemented cups. Our hypothesis was that the use of impaction bone grafts with the cemented cups will provide favorable outcomes in patients with acetabular bone defects for both primary and revision procedures. Methods: We retrospectively assessed the outcomes in 26 patients (mean age at surgery 45.3 years) who underwent THR with acetabular bone defect reconstruction using grafting and cemented cups. We performed 12 primary THRs and 14 revision THRs. Morselized grafts alone were used in eight patients, combined strut grafts and morselized grafts were used in five patients, acetabular rim mesh and morselized grafts were used in 12 cases, and a Kerboul cross ring and morselized grafts were used in one patient. All cases were clinically evaluated with the Harris Hip Score (HHS) in addition to radiological evaluation.
