Radiofrequency lesions of the dorsal root ganglion in the treatment of hip flexor spasm: a report of 2 cases

Abstract

The current popular model of spasticity is that the abnormalities are primarily due to increased sensitivity of the reflex arc at the segmental level of the spinal cord. Neurosurgical procedures, such as open selective dorsal rhizotomy for the reduction of spasticity, have been based on this assumption. We describe two patients with hip flexor spasm of different origin treated with radiofrequency lesions of the dorsal root ganglion.
