Denervation for the treatment of acquired spasticity of the brachioradialis
RA Meals
University of California, Los Angeles School of Medicine 90024.
Spasticity of the brachioradialis developed in three adolescent boys after
an episode of intracranial bleeding. The spasticity resulted in paradoxical
contraction of the muscle during attempted active extension of the elbow.
The flexed posture of the elbow was both dysfunctional and embarrassing to
the patient. A block of the radial nerve with lidocaine at the mid-humeral
level confirmed the diagnosis of paradoxical spasticity. After denervation
of the brachioradialis, the ability to extend the elbow markedly improved,
and the improvement was maintained at the time of follow-up which ranged
from two to five years.
