AbstractThis study was carried out to discover the prevalence, characteristics and severity of neuropathic pain after wide resection of chordoma of the sacrum by the use of posterior approach. Patients who had chordoma of their sacrums and underwent wide resection via posterior approach, during 1990-2002, were followed up as a prospective cohort. Pain assessment was carried out in terms of onset, characteristics, intensity (numerical rating scale), response to pain medication and associated symptoms. The correlation between patients' biographic data, preoperative neuropathic pain, type and levels of surgery and pain were analyzed. There were 21 patients; 14 male and 7 female patients. Their ages ranged between 29 and 75 years. Subtotal sacrectomy was carried out in 9 patients and total sacrectomy was carried out in 12 patients. All patients survived the operation. Neuropathic pain was found in 11 patients (52.4%). Male patients and presentation of preoperative neuropathic pain were significantly related to postoperative neuropathic pain. The other factors were not related to the postoperative pain. Recurrent of severe pain with different characteristics after the operation might indicate tumor recurrent. Early detection of the pain and proper treatment could minimize pain intensity and improved pain management satisfaction.
