| Abstract | ||||
| Background: It can be difficult to reconstruct acetabular flaws among revision hip arthroplasty cases. Tantalum acetabular augments are a novel strategy approach for treating uncontained acetabular deformities. This material has a higher coefficient of friction against bone and a lower bulk stiffness than conventional porous materials like titanium. This study aimed to evaluate clinical, and radiographical outcomes as well as complications of modular tantalum augment in hip arthroplasty. Subjects and methods: In a prospective cohort study, that was conducted on 12 cases who underwent fixation of tantalum augment in hip arthroplasty at Orthopedic Surgery Department, Faculty of Medicine, Zagazig University. Tantalum acetabular augments were used as a new approach for managing uncontained acetabular defects. Clinical and radiological outcomes were assessed of modular tantalum augment for 2 years post-operation. Results: There was a highly significant improvement in quality of life (WOMAC Osteoarthritis Index for function, pain, and stiffness) as well as SF-12 mental component after treatment (p<0.01), there was highly significant improvement of the UCLA Satisfaction scores after treatment (p<0.01). Conclusion: Satisfactory clinical as well as radiographic outcomes were obtained by modular Tantalum Augments for the reconstruction of acetabular defects in Total Hip Arthroplasty. This approach increases the rate of stable fixation | ||||
