Cordotomy should be reserved for patients with intractable pain resistant to conservative treatment that is not of a dysaesthetic type. The high cervical percutaneous technique permits exploitation of the principles of stereotactic surgery, especially physiological localization of the lesion site. The induction by 100 Hz stimulation of a warm or cool tingling in some portion of the contralateral half of the body without muscle tetanization ensures location within the spinothalamic tract while attention to the somatotopographic organization of the responses permits a certain degree of tailoring of the extent of analgesia to the patient's needs. During 264 consecutive procedures the spinothalamic tract was successfully located in 99% with a 0.3% incidence of significant persistent paresis.
脊髓切开术应仅用于对保守治疗无效且非感觉异常型的顽固性疼痛患者。高颈段经皮技术可利用立体定向手术的原理，尤其是病变部位的生理定位。通过100赫兹刺激对侧身体半部的某些部位诱发温暖或凉爽的刺痛感而无肌肉强直，可确保定位在脊髓丘脑束内，同时关注反应的躯体定位组织，可根据患者需求对镇痛范围进行一定程度的调整。在连续264例手术中，脊髓丘脑束成功定位率为99%，严重持续性轻瘫的发生率为0.3%。
