intercalary reconstruction
A surgical technique that replaces a segment of bone while preserving adjacent joints, commonly used in diaphyseal tumor resections.
Full Definition
Intercalary reconstruction refers to the surgical replacement of a bone segment while preserving the joints at both ends of the resected bone. This technique is primarily used for tumors located in the diaphysis (shaft) of long bones, where joint preservation is possible and desirable. Reconstruction options include massive allografts, vascularized autografts (such as fibular grafts), metallic implants, or composite reconstructions combining multiple techniques. Intercalary reconstruction aims to maintain joint function while providing adequate tumor resection margins. The choice of reconstruction method depends on factors including patient age, bone quality, expected lifespan, and functional requirements. This approach often provides better long-term function compared to joint replacement alternatives.
