Unilateral Vo thalamotomy in peripheral posttraumatic dystonia with complex regional pain syndrome

Intraoperative video during unilateral ventro-oral (Vo) thalamotomy in a middle-aged woman for peripheral posttraumatic dystonia with complex regional pain syndrome. An electrode was inserted into the right Vo nucleus, and coagulation was performed after electrical test stimulation. There were no apparent adverse reactions, and the patient showed improvement in symptoms, especially in the left leg, during the operation. Symptomatic improvement has been maintained postoperatively. (From: Kuramoto Y, Taira T, Tsuji S, Kubo T, Yoshimura S.
