ABSTRACT
OBJECTIVE:
Brachial plexus injury can produce a intractable chronic neuropathic pain. This study was undertaken to assess the long term outcome of microsurgical dorsal root entry zonotomy(MDT).METHODS:
Between October 1997 and December 2002, 21 patients received MDT because of a intractable pain resulting from brachial plexus injury. Of these, 19 patients were followed for more than 2 years. Fourteen of 19 patients were male and patient ages ranged from 22 to 69 years. Mean pain duration was 36.8 months and all patients had severe pain of 9~10 visual analogue scale. To achieve complete destruction of abnormal dorsal horns, thermocoagulation of the posterolateral sulcus were performed and careful gluing was done to prevent postoperative adhesion and pain recurrence.RESULTS:
Of the 19 patients, 15 patients had excellent (>75% reduction in pain) and good (51~75% pain relief) results in a average postoperative period of 4.1 years. One patient had a poor (less than 25% pain relief) result. Three patients were considered to have a fair result (26~50% pain relief). Postoperative complications were 2 transient ipsilateral ataxia and 1 CSF fistula that resolved without surgical revision.CONCLUSION:
These results indicate that MDT provides excellent long-term pain relief in medically intractable chronic neuropathic pain following brachial plexus injury without significant complications.
