Cerebral palsy is a common neurological disability syndrome in childhood, and it is a disease that seriously affects the survival and quality of life of children, and the number of children with cerebral palsy is increasing year by year, which brings great pain and burden to families and society. We timely applied the latest functional selective lumbosacral posterior roots resection (FSPR) to treat local children with cerebral palsy, which has changed the status quo of patients in Fujian having to travel to Shanghai and Beijing for surgical treatment. Recently, a 5-year-old girl from Xiamen, Xiao Yue (pseudonym), was successfully treated with FSPR and is currently undergoing post-operative rehabilitation. She was born with cerebral palsy due to the umbilical cord wrapped around her neck. She has multiple body deformities, severe muscle atrophy, and is unable to take care of herself. This is a kind of polyarticular contracture caused by congenital cerebral palsy: we performed this surgery in two sessions, the first one did all three of her joints together so that the legs could be separated, the legs straightened and the feet flattened. And after undergoing FSPR, Xiaoyue was able to straighten her legs, her foot surfaces have been flattened, and has been able to try to sit up after a period of rehabilitation. The FSPR procedure (functional selective lumbosacral posterior rhizotomy), which successfully helped Xiao Yue sit up and see the hope of standing, was developed based on the SPR procedure (selective posterior spinal nerve rhizotomy), which elevates the procedure from the anatomical level to the functional level. Specifically, the FSPR procedure is performed by intraoperative monitoring through multi-conductor electrophysiological technology to determine the proportion of posterior spinal nerve roots to be removed, making the scope and proportion of sensory nerves to be removed more scientific and objective. The patient’s muscle tone is adjusted comprehensively so that the muscle tone of spastic muscles is as close to normal as possible. Because 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 surgery can achieve comprehensive adjustment of muscle tone, and can provide long-term, stable and complete solution to the pain of muscle spasm in patients, providing the prerequisite for maximum recovery of their motor functions. In addition, it is worth mentioning that the FSPR procedure only selectively blocks part of the 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. We make a set of scientific and reasonable individualized treatment plans including preoperative evaluation and selection of appropriate methods before each surgery for different conditions of patients, and we should also insist on long-term formal rehabilitation training after the implementation of FSPR so as to ensure the rehabilitation efficacy. In addition, some patients should also undergo orthopedic surgery after FSPR, such as corrective treatment for deformities such as scissor gait and foot pronation. Spastic cerebral palsy is the most common form of cerebral palsy, and the current treatment mechanism consists of three steps: release of spasticity, correction of deformity, and rehabilitation training. This has led to a new breakthrough in the surgical treatment of cerebral palsy and has enabled many children with cerebral palsy to have a “new life”!
