RESUMEN
Rotation-plasty provides useful knee function and permits use of what is essentially an end-weight-bearing below-the knee prosthesis. This principle of rotating the foot was first used by Borggreve in 1930(3), in a patient with a short femur secondary to infection. Since then, this procedure has been used in congenital short femurs(4,6,7,), malignant bone tumors of the distal femur(1,5)and compound fracture with wide bone defect around the knee(2) We have performed this procedure in a case of focal femoral deficiency with 14cm shorter than the opposite femur due to long standing persistant chronic osteomyelitis in the mid-shaft femur of a nine-year old Korean boy and gave the good result with a conventional but slightly modified below- the-knee brace. The inverted foot was good to control the brace as a below-knee stump and heel functioned as a patella to support the body weight.

Rotation-plasty procedure was first done by Borggreve, in 1930 for the congenital short femur. Recently this procedure was used for the malignant bone tumor at the distal femur by Kotz and Salzer in 1982. In spite of its cosmetic problem of the distal stump, this procedure has great functional advantage of converting the above-knee amputation to the below-knee amputation. The authors applied this procedure in case of severe soft tissue crushing and large bone defect from the distal femur to the proximal tibia by the rail-road accident. Conventional below-knee prosthesis with thigh corset gave him normal ambulation. The inverted foot was good to control the prosthesis as a below-knee stump and heel functioned as a patella to support the body weight.
