METHODS: The peripheral nerve and skeletal muscle of 25 patients with spastic cerebral palsy were observed by gross examination during operation, and under microscope and electron microscope. RESULTS: Gross examination showed that peripheral nerve and skeletal muscle was normal during operation. Microscope showed that some skeletal muscle fibers degenerated, and the connective tissue proliferated. electronmicroscopically the damage of demyelination was extensive on the peripheral nerve; the pathological changes of Schwann's cell were sooner and more severe than axons; the pathological changes of myelinated nerve fiber were more obvious than the nonmyelinated nerve fiber; the lymphocyte were found around the microvasculature within the perineurium; the mitochondrion of skeletal muscle fiber increased in number, the sarcoplasmic reticulum and transverse tubule decreased and developed badly, the degenerative muscle fiber showed cell edema or the pathological changes of myofibril. All the peripheral nerve and skeletal muscle fiber affected had no repair and regeneration. CONCLUSIONS: The demyelination of the peripheral nerve of patients with spastic cerebral palsy is primary, and the skeletal muscle of patients with spastic cerebral palsy is secondary pathological change. The activity of nerve and muscle regeneration is bad.
