Who is suitable for SDR surgery? SDR surgery is for spastic cerebral palsy. Cerebral palsy is brain damage that occurs in an immature brain either prenatal, during birth or post-natal up to two years of the baby's life. Spasticity is described as "stiff muscles" as there is an increase in tension resulting in a continuous resistance to stretch. There are 3 main types of spastic cerebral palsy: Diplegic- where the spasticity affects just the lower limbs. Upper limbs can be mildly affected but it doesn't usually affect function Hemiplegic- Where the spasticity just affects one side of the body Quadriplegic- is where all 4 limbs are affected by spasticity. SDR surgery is the only surgery that results in a permanent reduction in spasticity. In the UK neurosurgeons only operate on diplegic children but in America they operate on all 3 types of Spastic Cerebral palsy but only treat the lower limb spasticity. SDR surgery is most effective between the ages of 3-11 years.
