Clinical study of modular external fixator for distal humeral metaphyseal-diaphyseal junction fractures in children

Modular external fixation demonstrated promising outcomes for pediatric distal humeral MDJ fractures, providing a minimally invasive treatment option with favorable functional recovery, and no second surgery is required to remove the internal fixation device. Low-position MDJ fractures (<20 mm) with a linear configuration can be sufficiently stabilized with K-wires, and the "triangular" configuration is more suitable for high-level fractures (≥20 mm).
