Preoperative planning

Diameter, length and depth of ILN insertion are determined by preoperative planning using the radiograph of the opposite intact femur if available. The nail’s largest diameter should be approximately 75% of the medullary cavity at the femoral isthmus. The longest possible nail should be selected to optimize construct stability (Dejardin et al: Interlocking nail and minimally invasive osteosynthesis Vet Clin Small Anim 42 (2012) 935–962).
