Abstract
Surgical destruction of a portion of the ventrolateral nucleus of the thalamus is currently the procedure of choice for the treatment of incapacitating tremor and rigidity of parkinsonism. Seventy-three patients were treated by 105 thalamotomies at the University of Alberta Hospital and assessed one to four years later for improvement of function in everyday activities. Fifty-six patients were improved, 12 were unchanged, and five had died. Only two of the deaths were related to the operation. Paresis was permanent in only one patient. Twenty-five patients had bilateral operations and 22 of these showed improvement of function. Contraindications to operation include serious cardiovascular disease, mental deterioration, and those parkinsonian patients whose disability is chiefly due to akinesia, oculogyric crisis, dysphasia or dysarthria.
