Trabecular titanium tailored implants in complex acetabular revision surgeries: our experience at minimum 3 years follow-up
Vol 34, Issue 5S1, 2020
Abstract
Hip revision surgery in cases with previous multiple reconstructive procedures is a challenging procedure. A custom-made product could be useful to obtain good results. Four cases (2 men and 2 women) of acetabular customized Trabecular Titanium (TT) implants made by 3D printed technology were performed. The mean age at surgery was 51.5 years (range 25-72). Patients were reviewed clinically and radiographically at follow-up. Mean Harris Hip Score increased significantly from 13.9 (range 6.9-20.6) preoperatively to 75.8 (range 53.9-94) at last follow-up (mean 43.5, range: 36-59), showing an improvement in terms of both pain relief, function and joint mobility. Radiographically neither signs of instability, migration nor tilting were observed. TT custom-implant made by high performance of the 3D-printing technology, system modularity, and patient-specific surgical tools permitted good clinical results and an effective restoration of the biomechanical joint parameters in these complex revision cases
