A systematic review was conducted for studies of any design. ⋯ Reviewed studies indicate promising results from dorsal root entry zone lesioning for the treatment of central neuropathic pain in selected patients with traumatic spinal cord injury. However, the strength of the evidence provided by the studies was poor in terms of study design, outcome measures, reports on the severity of adverse effects, patient selection criteria, and patient description. For these reasons, the evidence is weak for the use of dorsal root entry zone lesioning to relieve central neuropathic pain in patients with traumatic spinal cord injury.
