FSPR surgery is performed by selectively blocking the posterior root of the spinal nerve, which is a sensory branch, not a motor nerve. By cutting the posterior root of the spinal nerve, muscle tone can be significantly reduced. FSPR surgery has the following three main advantages: I. Small wound and quick recovery: the surgical incision is small, only 3 cm, and easy to recover. Second, the postoperative effect is obvious: the patient’s spasticity is completely lifted after surgery, and the effect of reducing muscle tone is good; it will not affect the motor function of the limb; it has little effect on sensory function; it can prevent the occurrence and development of limb deformity; there is obvious overall functional improvement and correction of power deformity. Third, safety: under the role of multilead electrophysiological monitoring, the application of intraoperative continuous recording of electromyography and somatosensory evoked potentials of multiple muscles of the limb, spinal evoked potentials make SPR surgery more scientific and objective basis, avoiding empirical surgery, subjective factors determine the failure of the proportion of the root after resection, minimize the risk of complications of surgery, further improve the efficacy of surgery, so that muscle tone is comprehensively reduction, and improved balance function. FSPR is a comprehensive adjustment of the patient’s muscle tone through the treatment of the posterior roots of the spinal nerves, so that the muscle tone of the spastic muscles 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.
