Acetabular reinforcement

Overview Reconstruction cages and rings restore the hip center of rotation in cases of severe acetabular bone loss encountered during revision total hip arthroplasty (THA).

Product description Revision acetabular cages and rings are structural implants used to bridge major bone defects, protect and contain bone grafts, and provide mechanical stability when biologic fixation is insufficient. These devices act as internal fixation constructs that distribute load and maintain hip geometry until graft incorporation or secondary fixation occurs.

Intended use Indicated for use in revision THA to manage severe acetabular bone loss and to restore the native hip center of rotation.

Typical clinical function

• Bridge massive acetabular defects
• Protect and contain bone grafts
• Restore the native hip rotation center
• Provide immediate mechanical stability in the absence of adequate biologic fixation

Notes Selection is based on defect pattern and load-distribution requirements; devices serve as structural scaffolds/internal fixation elements.

Characteristics / technical specifications

• Indication: Revision THA for severe acetabular bone loss
• Function: Structural scaffold / internal fixation to bridge defects and protect grafts
• Mechanical objective: Restore hip rotation center and ensure stable load distribution until graft incorporation
• Design intent: Versatility to address diverse defect patterns and to provide stability when biologic fixation is limited
