Selective spinal nerve root resection

Selective posterior rhizotomy (SPR) can effectively relieve limb spasm and lay the foundation for limb orthopedics and functional rehabilitation. As early as the beginning of this century, Foerster (1908) first used spinal nerve posterior root resection to treat limb spasms. He used a complete posterior root cut to completely cut off the limbs. Although this could successfully relieve limb spasms, the complete posterior root nerve was completely removed. Cutting does not preserve the feeling of the limbs, so this operation is not acceptable to most scholars. Half a century later, French scholar Gros (1967) improved the previous operation of Foerster. According to a certain proportion, he cut off only a part of the posterior root fibers. As a result, although the physical integrity of the limb was preserved, the spasm was not completely relieved. Therefore, the operation has not been promoted. In the late 1970s, Italian scholar Fasano (1978) first reported that selective electrical spinal nerve root resection was performed using electrical stimulation. While completely relieving spasm, he successfully retained the sensation of the limbs and found that a considerable part The case had significant functional improvement. This successful experience has gradually attracted widespread attention from scholars in various countries. Fasano also called this operation a functional posterior root resection. In the 1980s, SPR surgery was introduced into North America. Peacock (1988) further improved Fasano's surgical method, and lowered the SPR operation plane from thoracolumbar (chest 12 and lumbar 1.2) to lumbosacral (L2-S1). Performing the operation at the horsetail level reduces the risk of trauma to the spinal cord cone, reduces the difficulty of the operation, and promotes the operation in North America. Chinese scholar Professor Xu Lin first launched SPR surgery for cerebral palsy in China and Asia in May 1990. The Department of Orthopaedics, Zhongyuan Oilfield General Hospital successfully carried out this operation in 1999 and achieved satisfactory results.
