rotationplasty
A limb salvage procedure where the ankle is rotated 180 degrees to function as a knee joint after tumor resection or congenital deficiency.
Full Definition
Rotationplasty, also known as Van Nes rotation or Borggreve rotation, is a specialized limb salvage procedure primarily performed for bone tumors of the distal femur or proximal tibia, or in cases of severe congenital limb deficiencies. The procedure involves removing the affected bone segment and rotating the remaining lower leg 180 degrees, so that the ankle joint functions as a knee joint. The foot, now pointing backward, fits into a prosthetic limb that provides excellent functional outcomes. While the cosmetic appearance may be challenging for some patients, rotationplasty offers superior function compared to above-knee amputation.
Usage
Usage note: Often written as one word, though 'rotation plasty' (two words) is also acceptable.
