Radiographic Evaluation of Bony Ingrowth of Highly Porous Cups: A Study of 47 Patients Cadaveric Pelvises

Description

The presentation discusses research on bony in-growth of highly porous cups in 47 cadaveric pelvis samples. It begins with disclosures and shifts to the context, noting total hip arthroplasty as the standard treatment for chronic osteoarthritis yet experiencing significant lifetime revision rates (28%). The study aims to analyze osseointegration of uncemented acetabular implants using multimodal radiographic analysis (X-ray, CT, and MRI). X-rays provided limited 2D views while CT and MRI offered 3D views but differed in soft tissue and bone density visualization. The results showed an average bony in-growth of 82%, with a range from 50% to 100%. Notable findings included 36% of specimens showing medial wall perforation and 30% displaying posterior superior quadrant lucency. Despite the variations in bony in-growth, the study found no correlation between the years since the surgery and the degree of bony in-growth. The presentation concludes with the importance of future histological studies on bony in-growth and opens the floor for questions, inviting further discussion on technical aspects like implant specifications and bone remodeling.
