intercalary graft
A bone graft placed between two remaining bone segments to bridge a defect after tumor resection.
Full Definition
An intercalary graft is a reconstructive technique used in orthopedic oncology to bridge segmental bone defects created after tumor resection. The graft is placed between two intact bone ends, preserving adjacent joints and maintaining limb length and function. Intercalary grafts may be autografts (commonly vascularized fibula), allografts from bone banks, or synthetic implants. The choice depends on defect size, patient age, expected activity level, and available donor sites. Successful integration requires adequate soft tissue coverage and appropriate internal fixation.
Usage
Usage note: Specify graft type (autograft, allograft, or prosthetic) for clarity in documentation.
