Bilateral cervical posterior rhizotomy: effects on dystonia and athetosis, on respiration and other autonomic functions.
Appl Neurophysiol, 40 (1):
26--40 (1977)Abstract
Bilateral cervical posterior rhizotomy of C1 through C4, C5 or C6 was performed in 16 patients affected by dystonia and athetosis resulting from infantile cerebral palsy. The majority showed decreased muscle spasms and athetoid movements, with some improvements in their posture and voluntary mobility. 5 patients suffered from uneven and irregular breathing associated with lethargy immediately postoperatively, and 4 also showed reduced diaphragmatic activity; all 4 of these patients developed pneumonia, transitory in 3, but fatal to the other. Urinary retention lasting for a maximum of 3 months occurred in 4 of the 5 patients. The authors suggest that the lesion of ascending reticular fibers in the cervical posterior roots could have been responsible for the observations.
