ABSTRACT
Spastic palsies are still a challenge to the surgeon. In fact the various surgical techniques of the so-called ‘classical’ surgery still end up in failure in a great number of patients. Spasticity depends on central neurological lesions involving the pyramidal system at various levels. (Lusskin et al 1968, Dujovny et al 1980). The etiology includes perinatal encephalitis, brain diseases in children, and vascular or traumatic hemiplegia in adults.
