Microsurgical ablative procedures in the peripheral nerves and dorsal root entry zone for relief of focal spasticity in the limbs.

When spasticity is harmful and localized in the limb(s), ablative procedures in the peripheral nerves or the dorsal root entry zone (DREZ) can be useful. The authors report on the long-term results of (1) selective tibial neurotomy in a series of 62 spastic feet, and (2) microsurgical DREZ-tomy in a series of 69 patients affected with hyperspasticity in the entire upper or lower limb(s).
