Rhizotomy Surgery at the Conus Medullaris.

Selective dorsal rhizotomy (SDR) has been an important surgical treatment for spasticity for decades. Broadly, there are two surgical technique options-via a multilevel laminotomy/laminectomy or via a single-level laminectomy and conus approach. This latter approach is described in detail in this chapter, with discussion of patient selection and a focus on surgical techniques including the integration of electromyography (EMG).
