Intramedullary versus crossed pinning for paediatric distal radius fractures: clinical decision patterns and biomechanical validation integrating real-world practice with growth plate stress finite element analysis
Both techniques yielded excellent outcomes when applied per observed patterns (IM for younger/proximal; CP for older/distal fractures). Position-dependent FEA insights, showing enhanced CP torsional advantages proximally, support an observed clinical practice pattern suggesting an approximate 20-25 mm threshold that warrants prospective validation. Limitations include retrospective design, unmodeled cast effects, and FEA simplifications.
