Surgery may be needed to lessen muscle tightness or correct bone abnormalities caused by spasticity. These treatments include:
Children with severe contractures or deformities may need surgery on bones or joints to place their arms, hips or legs in their correct positions.
Surgical procedures can also lengthen muscles and tendons that are proportionally too short because of severe contractures. These corrections can lessen pain and improve mobility. The procedures may also make it easier to use a walker, braces or crutches.
In some severe cases, when other treatments haven't helped, surgeons may cut the nerves serving the spastic muscles in a procedure called selective dorsal rhizotomy. This relaxes the muscle and reduces pain, but can also cause numbness.
