Cerebral palsy is also known as cerebral palsy, or cerebral palsy for short. It refers to the damage of brain cells caused by the stimulation of various injury factors before or within one month after birth, resulting in upper motor neuron damage, which can lead to mental retardation, motor ataxia, motor and sensory impairment, etc. The most common postural abnormalities include head tilting back, eye strabismus, inward rotation of the upper limbs with hands behind the back, and inward tiptoeing of the lower limbs. Most of the mothers have a history of difficult delivery, and most of the children have hypoxia and asphyxia before and after birth. Up to 75% of children with cerebral palsy are spastic, and their tone is significantly higher than that of similar normal children. When the child is exposed to various stimuli such as exertion, agitation, loss of balance, fear or anxiety, this can further increase muscle tone. Children with more severe spasticity have significantly reduced limb movements, and their movements are stereotyped and awkward, often with their heads not in a central position, often turned to the side or tilted back, with their hands and shoulders rotated, flexed or extended downward; their hands are often in a fist shape, with the thumb against the palm and the other four fingers holding the thumb, with the back of the hand facing forward and the palm downward; the spine is often kyphotic or scoliosis to varying degrees, and the hip joint is often not fully extended but The lower extremities are often crossed and the Achilles tendon is tense, resulting in the sole of the foot being unable to be flattened when standing and can only land on the toes. At present, we have improved and upgraded the traditional SPR surgery with the new FSPR (Functional Selective Spinal Nerve Partial Dissection) for children with spastic cerebral palsy, and achieved excellent results: the use of intraoperative evoked potentials and electromyographic recording technology to monitor the entire operation makes the operation more objective and maximally overcomes the subjectivity of total reliance on experience; It also makes the surgical treatment of cerebral palsy more scientific and becomes another leap forward in the treatment of cerebral palsy. In detail, FSPR is to comprehensively adjust the patient’s muscle tone by treating the posterior roots of spinal nerves, so that the muscle tone of several spastic muscles or muscle groups of the patient is as close to normal as possible, and it can solve the pain of muscle spasm of the patient in a long-term, stable and thorough way, providing the prerequisite for the maximum recovery of their motor function. It is worth mentioning that FSPR only selectively blocks part of the patient’s posterior nerve root fibers, without affecting the anterior nerve roots that govern muscle movement and motor function. The specific site of surgery can depend on the patient’s specific condition: surgery in the lumbar spine can address lower extremity spasticity, and surgery in the cervical spine can address upper extremity spasticity. Currently, FSPR in the lumbosacral segment is mainly used in clinical practice for treatment, with restrictive resection of the spinous processes and laminae of L2 to L5 to preserve each small intervertebral joint (open window method and jump method). Compared with the previous treatment methods, we have made some improvements, such as: identifying and separating the anterior and posterior spinal nerve roots from L2 to S1, dividing the posterior spinal nerve roots into small bundles; electrical stimulation by nerve threshold measuring instrument to induce spasm in both lower limbs, determine the threshold, and cut off the nerve bundle branch with higher threshold; adopting intraoperative electrophysiological monitoring technology and continuous intraoperative recording of polysomnography to make the operation more scientific and objective, overcoming the blindness of subjective experience, and improving the efficacy and reducing complications. Improve the efficacy and reduce complications; unilateral hemivertebral plate incision with preserved spinous process 0.6cm method to treat unilateral limb spasticity. At present, FSPR has become the first choice for the treatment of spastic cerebral palsy patients at home and abroad, and the results are most direct and significant. It should be noted that a set of scientific and reasonable individualized treatment plan should be established for each pediatric cerebral palsy patient before surgery, including preoperative evaluation and selection of appropriate methods, and long-term formal rehabilitation training should be adhered to after the implementation of FSPR to ensure the rehabilitation efficacy. In addition, it should be remembered that cerebral palsy treatment is a multi-stage long-term work that requires the collaboration of different professionals, teamwork, active participation of parents, and social support to achieve effective control of disease symptoms and functional improvement more quickly.
