Selective resection and denervation of cervical muscles in the treatment of spasmodic torticollis: results in 60 cases.

The author presents a series of 60 patients with torticollis who were treated successfully by operation. He describes the clinical types of torticollis: rotational torticollis, retrocollis, antecollis, lateroflexional torticollis, and combined types. The muscular mechanism of torticollis is detailed, and the operative technique of resecting or denervating only the principal or motive muscles is explained and illustrated for each type of torticollis. The results in this series were very good: 83.3% recovered completely or were improved markedly, and there were no complications.
