The problem with percutaneous and even stereotactic cordotomy is the difficulty in obtaining sufficiently high analgesic levels without autonomic complications, although the problem seemed to apply to relatively few patients since percutaneous and stereotactic spinal procedures achieved sufficiently high analgesic levels to encompass most patients' pain. There is a group of patients, however, with high pain in the shoulder and neck where conventional percutaneous and stereotactic spinal procedure are dangerous. From the standpoint of achieving high levels of analgesia with a low incidence of dysaesthesia, pontomedullary lesions appear to have advantages.
经皮甚至立体定向脊髓切断术的问题在于，难以在不引发自主神经并发症的情况下获得足够高的镇痛水平，尽管自从经皮和立体定向脊柱手术能够达到足够高的镇痛水平以涵盖大多数患者的疼痛以来，这个问题似乎仅适用于相对较少的患者。然而，有一组患者肩部和颈部疼痛剧烈，传统的经皮和立体定向脊柱手术对他们来说很危险。从实现高镇痛水平且感觉异常发生率低的角度来看，脑桥延髓病变似乎具有优势。
