In the past, the treatment of cerebral palsy was mainly conventional physical therapy and rehabilitation training. However, due to the high muscle tone of the child’s limbs and the severely restricted joint movement, they often have fear and resistance to these conventional treatments, and the treatment effect is not good. In recent years, functional neurosurgery has been developed to reduce the muscle tone of the child and improve the degree of joint movement, thus improving the effectiveness of rehabilitation treatment. Currently, in addition to Achilles tendon lengthening, functional neurosurgery is able to perform the following types of procedures: 1) intramuscular injections with BOTOX neuroelectric navigation; 2) selective posterior nerve root dissection (SDR); and 3) BACLOFEN continuous intrathecal injections. These types of procedures are suitable for different patient types and the postoperative results are satisfactory.
