“…In their report, a total of 12 patients were treated with thalamotomy, and their mean WCRS significantly decreased from 13.1 to 0.8 at 3-33 months after surgery. Surgical results of thalamotomy in the other 13 patients were very similar (table 1) [17,18,19,20,24,25]. Thus, the clinical symptoms resolved in 21 patients and improved in 3.…”

“…Since 1969, there have been 11 publications, including this report, in which a total of 31 patients who underwent stereotactic surgery for writer's cramp have been treated (table 1) [15,17,18,19,20,21,22,23,24,25]. They included 21 males and 5 females; the gender of the other 5 was not described.…”

“…The mean disease duration in 26 cases was 7.1 years, ranging from 2 to 25 years. Stereotactic surgery included 25 thalamotomies since 1969 [15,17,18,19,20,23,24,25] and 6 DBS since 2007 [21,22]. The target was the Vo in 17 cases, the Vim in 3, both Vo and Vim in 7, and unknown region of thalamus in 4.…”

“…Subsequently, deep brain stimulation (DBS) has also been applied to treat dystonia [16]. The first stereotactic surgery for writer's cramp was reported in 1969 [17]. Since then, the ventral oral nucleus (Vo) [18,19,20,21,22,23] and/or ventral intermediate nucleus (Vim) [21,24] of the thalamus are the common surgical targets.…”

Background: Writer's cramp is a specific movement disorder with hand muscle cramps in writing, being classified into focal and action-specific dystonia. Stereotactic surgery, such as thalamotomy and deep brain stimulation (DBS), has been reported for writer's cramp; however, the number of reported cases is still scarce and surgical procedures are also controversial. Objectives: In this study, therefore, we present 2 patients who underwent thalamotomy for writer's cramp and systematically review the literature on stereotactic surgery for writer's cramp. Methods: Case reports and literature review are presented. Results: Both patients underwent ventral oral nucleus (Vo) thalamotomy safely. Their symptoms completely disappeared after surgery and did not recur during follow-up periods. In the literature, a total of 31 cases were surgically treated for writer's cramp. Stereotactic surgery included thalamotomy in 25 cases and DBS in 6. The target included the Vo in 17 cases, the ventral intermediate nucleus (Vim) in 3, and both Vo and Vim in 7. Both procedures markedly improved or resolved the symptoms. Transient neurological deficits were observed in 16.0% of patients after thalamotomy. Conclusions: The Vo may be the most effective target to treat writer's cramp. Both thalamotomy and DBS are feasible and effective, but thalamotomy would be a better option, especially in younger or high-risk patients.

J Korean Neurosurg Soc 46 : [52][53][54][55] 2009 Writer's cramp is a type of idiopathic focal hand dystonia characterized by muscle cramps that accompany execution of the writing task specifically. There has been renewed interest in neurosurgical procedures for the treatment of dystonia over the past several years. In particular, deep brain stimulation (DBS) has received increasing attention as a therapeutic option for patients with dystonia. However, to date, limited reporters made investigations into DBS in relation to the Writer's cramp. In this case, unilateral Ventro-oralis complex (Vo) DBS resulted in a major improvement in patient's focal dystonic movement disorders. Her post-operative Burke-Fahn-Marsden Dystonia Rating (BFMDR) scale demonstrated 1 compared with pre-operative BFMDR scale 4. We conclude that thalamic Vo complex DBS may be an important neurosurgical therapeutic option for Writer's cramp.
