tumor prosthesis
Specialized orthopedic implant designed for reconstruction after oncological bone resection.
Full Definition
A tumor prosthesis is a custom or modular orthopedic implant specifically engineered to reconstruct large skeletal defects created by oncological resection. These prostheses differ from conventional joint replacements in their ability to span extensive bone defects, often incorporating both joint surfaces and significant portions of bone shaft. Modern tumor prostheses feature modular designs allowing intraoperative customization, specialized attachment mechanisms for soft tissue reconstruction, and materials selected for longevity in young patients. They represent the most common reconstructive option for metaphyseal and osteoarticular defects in orthopedic oncology.
Usage
Usage note: Specify whether custom or modular design in surgical documentation.
