intercalary defect
Segmental bone defect requiring reconstruction of the diaphyseal or metaphyseal region while preserving adjacent joints.
Full Definition
An intercalary defect refers to a segmental bone defect created after tumor resection that involves the diaphyseal or metaphyseal region while preserving one or both adjacent joints. This type of defect commonly occurs after resection of diaphyseal tumors and requires specialized reconstruction techniques to restore skeletal continuity and function. Reconstruction options include intercalary allografts, modular endoprostheses, or vascularized autografts. The term distinguishes this defect type from osteoarticular defects that involve joint surfaces and require different reconstructive approaches.
Usage
Usage note: Specify the anatomical location and length when documenting intercalary defects.
