- •
An intramedullary lengthening nail with a shape memory alloy (SMA) element as drive was constructed.
- •
Transcutaneous induced electromagnetical energy with a phase frequency of 25 kHz (13 V / 12 W) is required to drive the nail.
- •
Three prototypes were tested in cadaver lab in antegrade and retrograde femoral and tibial configuration.
- •
Additionally an acoustic feedback signal (“click”) was used as a check-up success.
- •
SMA as drive for active bone implants for limb lengthening opens up the prospect of a distraction method highly promising.
