Focal Dystonia in Hemiplegic Upper Limb: Favorable Effect of Cervical Microsurgical DREZotomy Involving the Ventral Horn - A Report of 3 Patients.
Abstract
[BACKGROUND] Focal dystonia in hemiplegic upper limbs is poorly responsive to medications or classical neurosurgical treatments. Only repeated botulinum toxin injections show efficacy, but in most severe cases effects are transient.
[OBJECTIVES] Cervical DREZ lesioning, which has proven efficacious in hyperspasticity when done deeply (3-5 mm) in the dorsal horn, may have favorable effects on the dystonic component when performed down to, and including, the base of the ventral horn (5-6 mm in depth).
[METHODS] Three patients underwent deep cervical microsurgical DREZotomy (MDT) for focal dystonia in the upper limb.
[RESULTS] Hypertonia was reduced, and sustained dystonic postures were suppressed. Residual motor function (hidden behind hypertonia) came to the surface.
[CONCLUSIONS] Cervical MDT may be a useful armamentarium for treating refractory focal dystonia in the upper limb.
