Validation of a proposed radiographic bone defect classification system.

Objectives: To clinically validate a recently proposed classification scheme of post-traumatic bone defects.

Methods And Materials: Open fractures were classified utilising a newly introduced classification system. This classification system is based on plain radiographs, assessing the extent and local geometry of bone loss, including: D1 - Incomplete Defects; D2 - Minor/Sub-Critical (Complete) Defects (<2 cm); and D3 - Segmental/Critical Sized Defects (≥2 cm).
