SDR is a surgical procedure that has been used for many years but has not been routinely available within the NHS. The SDR procedure is used to improve spasticity in children with cerebral palsy and involves dividing nerve fibres running from the muscles back to the spinal cord. While it is believed that SDR is effective, there are no definitive data. In July 2014 NHS England commissioned five NHS Trusts to undertake SDR surgery in eligible children for a two year period, and to collect detailed information on their outcomes. A database has been developed by the KiTEC in conjunction with NHS England and the national clinical SDR steering committee. The proposed database will aggregate these data from the five centres and analyse them to provide overall evidence on the clinical effectiveness of SDR.
