Biochemical Modelling Identifies Fracture-Specific Pin Configurations for Paediatric Elbow Fixation .

Does the optimal Kirschner-wire configuration change with supracondylar humeral fracture height? Researchers evaluated 27 finite-element models comparing crossed-wire fixation angles across low, middle and high fracture levels. Smaller insertion angles appeared favourable for low fractures, mixed angles for middle fractures and larger bilateral angles for high fractures. The findings offer a biomechanical rationale for tailoring pin placement to fracture morphology. However, computational stability does not establish improved fracture healing, fewer complications or better functional outcomes in children.
