The document details Mobelife's workflow for patient-specific acetabular revision implants. CT data is converted to 3D bone models, implants are designed with surgeon input, and Abaqus finite element analysis evaluates mechanical integrity, screw placement, and bone loading before additive manufacturing. A real patient case with pelvic discontinuity demonstrates reduced pain and faster recovery after surgery.

Key takeaways

CT-derived 3D models enable precise reconstruction of deficient pelvic bone stock for revision implants.

Abaqus FEA simulates patient-specific muscle forces, cortical and trabecular properties, and implant-bone interaction.

Preoperative planning includes screw trajectory optimization and porous structure design to restore stability.

Additive manufacturing produces ISO 13485-certified titanium implants and surgical jigs from validated designs.

Simulation reduces risk of stress shielding and mechanical failure in complex revision hip arthroplasty.
