A new myelotomy knife is described and a procedure, designed to sever certain reflex connections while preserving as many corticospinal connections as possible, is presented. Through intermittent dorsal midline incisions the gray matter lateral to the central canal is severed bilaterally under the microscope from L-1 to S-1. This procedure relieved mass spasms and hyperactive reflexes in 14 paraplegic or tetraplegic patients, but preserved postural reflexes and whatever voluntary motor power the patients had prior to myelotomy. Before myelotomy all patients were bedridden. Afterward nine patients were able to use a wheel chair and five were able to walk with the use of parallel bars or crutches.
本文描述了一种新型脊髓切断刀，并介绍了一种旨在切断某些反射连接同时尽可能保留更多皮质脊髓连接的手术方法。通过间歇性的背侧中线切口，在显微镜下从L-1至S-1双侧切断中央管外侧的灰质。该手术缓解了14例截瘫或四肢瘫患者的全身性痉挛和反射亢进，但保留了姿势反射以及患者在脊髓切断术前拥有的任何自主运动能力。在进行脊髓切断术之前，所有患者均卧床不起。术后，9例患者能够使用轮椅，5例患者能够借助双杠或拐杖行走。
