Implant Failure after Externally Magnetic-controlled Nail Lengthening

Leg length discrepancy (LLD) has variable causes, such as congenital malformations, posttraumatic growth arrest, fracture, malunion, malignancies or infections. Besides aesthetic issues, significant LLD may cause an asymmetry of weight distribution [1] that leads to joint pain over time. Hip, knee and the lower back are affected particularly [2]. A first approach with external devices had acceptable results but showed a variety of complications, e.g. pin-tract infections, pin side pain and scarring [3, 4].
