There are more than 6 million cerebral palsy patients in China who need treatment and rehabilitation. There are 8 types of cerebral palsy, 75% of which are spastic cerebral palsy, whose movement disorders can involve the whole body, and the clinical involvement of both lower limbs is the most common, mainly manifesting as knee and hip flexion in the lower limbs, toeing on the ground when standing, tiptoeing and heel not touching the ground when walking. Early detection and rehabilitation are needed for pediatric cerebral palsy. Some children with satisfactory rehabilitation results do not even need surgery. However, for children older than 3 years old, especially those with spastic cerebral palsy, which has the highest incidence, general rehabilitative treatment can no longer achieve functional rehabilitation. At present, the international standardized diagnosis and treatment process should be rehabilitation → FSPR surgery → orthopedic surgery → rehabilitation, and one-sided emphasis on the efficacy of a certain method or a certain technique is unscientific and undesirable. For older children who have developed joint deformities, FSPR surgery alone is not enough, and orthopedic treatment may be required to achieve a more desirable result, so that the child can be as close to a normal child as possible, with a normal walking gait and no more “tiptoeing”. As children with spastic cerebral palsy get older, the dystonia becomes higher and the deformity becomes more severe. Therefore, FSPR surgery is needed to locate and quantitatively cut the posterior roots of the crestal nerve, so that the muscle tone can be reduced to a level close to normal, in order to ensure the effectiveness of rehabilitation, avoid recurrence of spasticity, improve motor function, and enable them to return to society. Treatment principle of FSPR surgery The Chinese name of FSPR surgery is functional selective crural nerve heel dissection. Simply put, FSPR is to comprehensively adjust the patient’s muscle tone by treating the posterior roots of the crural nerve, so that the muscle tone of the spastic muscle is as close to normal as possible. The muscle spasm in cerebral palsy patients is not limited to a single muscle, but often manifests as spasm of multiple muscles or muscle groups, and this procedure can achieve a comprehensive adjustment of muscle tone, and can provide a long-term, stable and complete solution to the patient’s muscle spasm pain, providing a prerequisite for the maximum recovery of his motor function. FSPR surgery is performed under the role of multilead electrophysiological monitoring, applying intraoperative continuous recording of EMG and somatosensory evoked potentials of multiple muscles of the limb, and cremaster evoked potentials make FSPR surgery more scientifically and objectively based, avoiding empirical surgery, the failure of subjective factors to determine the proportion of the root after resection, minimizing the risk of complications of surgery, further improving the efficacy of surgery, enabling muscle tone to be The overall reduction of muscle tone and improvement of balance function. Three characteristics of FSPR surgery 1, effective: FSPR surgery is performed by selectively blocking the posterior root of the cremaster nerve, which is a sensory branch, not a motor nerve, with significant antispasmodic effect and no recurrence, creating a good basis for further rehabilitation. 2. Safety: By cutting the posterior roots of the cremaster nerve, muscle tone can be significantly reduced, but it will not cause paralysis in children after surgery. Very few children may have transient abnormalities of urination and defecation, which are caused by the stimulation of the cremaster nerve during surgery and can be recovered after surgery. Through the modified way, the crestal stability and force line will not be greatly affected. 3, selective: functional selective cremasteric nerve posterior root dissection (FSPR) has three meanings: one is to select the appropriate case, the other is to select the nerve distribution segment that releases the spasm, and the third is to selectively cut the posterior root with small bundles with low threshold by electrical stimulation.
