Reconstruction Cages/Rings

Revision acetabular cages and rings represent a critical class of implants in the orthopedic surgeon’s armamentarium for addressing severe acetabular bone loss during total hip arthroplasty (THA) revision.

Unlike standard hemispherical cups or modular augments, these devices function as structural “scaffolds” or “internal fixation plates” that bridge massive defects, protect underlying bone grafts, and restore the native hip center of rotation. Their product features are funda- mentally oriented toward providing mechanical stability in the absence of biologic fixation, versatility in addressing diverse defect patterns, and durable load distribution until graft incorporation occurs.
