Ventral intermediate thalamotomy for posttraumatic hemiballismus.
An unusual case of hemiballismus following closed head injury is presented. The abnormal movement persisted for 16 years despite medical treatment. Preoperative studies did not reveal a specific lesion within the subthalamic nucleus or within the basal ganglia. A stereotactic ventral intermediate thalamotomy was performed producing a complete resolution of the ballistic movement which persisted for the length of our 12-month follow-up.
