Juvenile, focal dystonia, post-traumatic tremor disorder (PTTD), and choreoathetoid cerebral palsy (CACP) after a moderately severe closed head injury are uncommon conditions. Medical treatment has been largely unsuccessful. Stereotactic thalamotomy has been the most frequently used treatment for medically refractory PTTD and dystonia, with reasonable success. However, a particularly high rate of complications has been reported with thalamotomies in the treatment of these conditions (up to 30%). Limited data seem to suggest that ventral posterior pallidotomy offers a valid option without the significant complications associated with thalamotomy. Patients referred to the Arkansas Children's Hospital for surgical treatment of PTTD (6), dystonia (2), and CACP were reviewed for details regarding their neurological presentation, clinical and radiographic findings, and post-operative follow-up. All patients underwent stereotactic pallidotomy with radiofrequency lesioning following a macro-electrode stimulation mapping of the globus pallidus. Preliminary localization of the lesion target was determined with magnetic resonance imaging and ventriculographic...
