Conus Dorsal Root Entry Zone Rhizotomy for Lower Limb Spasticity

Abstract

Rhizotomy is commonly performed for lower limb spasticity. However, it requires neuromonitoring, which may not be available in the majority of neurosurgical centers in developing countries. In addition, it involves cutting of the dorsal roots, which may lead to sensory symptoms in patients. Conus DREZ-otomy (dorsal root entry zone rhizotomy) is an attractive alternative as it does not require any neuromonitoring and does not entail destruction of any roots. However, a meticulous surgical technique is required for performing this procedure. In this article, we have described the operative technique of Conus DREZ-otomy performed by the senior author (D.
