Summary

Interlocking nails have been shown to be an effective means to stabilise long bone fractures. When used in non-load sharing fracture repairs with minimal medullary canal filling, the authors noted instabilityofthe main fracture fragments. The addition of multiple intramedullary pins in stack pin fashion eliminated the instability. ILN and ILN/SP constructswere loaded in four-point bending using an unstable osteotomy model. The gap between the ILN and ILN/SP groups was compared. Significant changes were seen with the ILN/SP constructs in the cranial to caudal plane.
