A comparative biomechanical study of the Distal Tibia Nail against compression plating for the osteosynthesis of supramalleolar corrective osteotomies

Résumé

The Distal Tibia Nail (DTN; Mizuho, Japan) has demonstrated higher biomechanical stiffness to locking plates in previous research for A3 distal tibia fractures. It is here investigated as a fixation option for supramalleolar corrective osteotomies (SMOT). Sixteen Sawbones tibiae were implanted with either a DTN (n=8) or Medial Distal Tibia Plate (MDTP; n=8) and a SMOT simulated. Two surgical outcome scenarios were envisaged: 'best-case' representing an intact lateral cortex, and 'worst-case' representing a fractured lateral cortex. All samples were subjected to compressive (350N, 700N) and torsional (±4 Nm, ±8 Nm) testing. Samples were evaluated using calculated construct stiffness from force-displacement data, interfragmentary movement and Von Mises' strain distribution. The DTN demonstrated a greater compressive stiffness for the best-case surgical scenario, whereas the MDTP showed higher stiffness (p
