Study of Custom-Made Acetabular Implants Using 3D Printing for Adults Undergoing Hip Revision Surgery with Severe Bone Loss

What this Trial Is About

This research evaluates custom-made acetabular implants designed for adults undergoing revision hip surgery due to severe bone loss, specifically Paprosky 3 defects, for non-cancerous reasons. The study aims to validate this personalized implant technology made using additive manufacturing based on pre-operative CT scans to address challenges in complex hip revisions. It focuses on clinical and radiological outcomes, perioperative complications, and implant survival in patients with severe acetabular bone damage. Participants receive a custom implant tailored to their bone defect using a CT scan to create a personalized device with a porous surface to support bone integration. The implant is accompanied by specialized tools for surgery and produced by an external company following approved manufacturing practices. Preoperative evaluations include clinical scoring and bone loss assessment, with data collected on surgical complications and postoperative recovery. Participants attend follow-up visits at 1, 3, 12, 24, and 36 months after surgery for clinical and radiographic evaluations. Assessments include the Harris Hip Score, patient-reported outcomes, satisfaction levels, and detailed imaging to measure implant positioning and bone integration. Researchers track complications, implant stability, and revision rates, providing comprehensive monitoring of outcomes up to 18 months and beyond.
