Some cancers, such as sarcoma, can occur in the various parts of the soft tissue in and around the bone. Removing these tumors while saving the limb is important for both getting rid of the cancer and preserving function for the patient.

Bone tumor removals in children requires careful planning, in order to help save healthy (and still growing) bone. Special adjustable prostheses are used in these cases to help equalize limb length between both sides as the child grows.
