Rotationplasty

Rotationplasty is a unique surgical procedure that is used to treat bone cancers, particularly in the lower limbs. It involves the removal of a portion of the limb, usually the knee, and the rotation and reattachment of the lower limb. This procedure is often used in cases where limb-sparing surgery is not possible, or where the patient's quality of life would be significantly improved by the procedure.

Procedure

The procedure begins with the surgical removal of the diseased portion of the limb. This is typically the knee, but can also include portions of the thigh or lower leg. Once the diseased portion has been removed, the remaining lower limb is rotated 180 degrees and reattached. This rotation allows the ankle to function in place of the removed knee, providing the patient with a functional, albeit shorter, limb.

Indications

Rotationplasty is most commonly used to treat bone cancers, such as osteosarcoma and Ewing's sarcoma. It is often used in cases where limb-sparing surgery is not possible, or where the patient's quality of life would be significantly improved by the procedure. It is also used in cases where the patient is a child and future growth is a consideration.

Benefits and Risks

The primary benefit of rotationplasty is the preservation of limb function. By using the ankle as a functional knee, patients are often able to regain a significant amount of mobility and independence. However, there are also risks associated with the procedure. These can include infection, nerve damage, and psychological distress related to the altered appearance of the limb.
