Background: The amount of total hip arthroplasty (THA) surgeries conducted yearly is on the rise, and this trend is also noticeable in revision hip procedures. However, reconstructing acetabular defects during revision THA can be difficult. Successful revision surgery requires achieving press-fit of the implant, bridging bony defects, and restoring the center of rotation of the hip. Various approaches have been implemented to attain these objectives. Aim: to evaluate early functional and radiological outcomes in patients undergoing revision THA with acetabular defects using trabecular metal augments for reconstruction of the acetabulum. Patients and methods : A prospective cohort study was conducted in Benha university hospital including twenty patients undergoing revision THA with acetabular defects that necessitate reconstruction between April 2019 and December 2022 in using trabecular metal augment. Results: The average age of the patients examined was 59 years old. The majority of the patients were found to have a Paprosky type 2B defect (45%) according to classification. Out of the total patients, 55% (11 patients) had excellent results as per the Oxford Hip Score, 40% (8 patients) showed good results, and only 5% (1 patient) showed fair results. The average time of postoperative follow-up was 16 months. Conclusion: porous metal augments are considered a valuable method in the management of acetabular defect due to its modularity and the ability to reconstruct different types of defects with no fear of bone resorption. |
