Rhizotomy carries small but significant risks of nerve damage, permanent loss of sensation or altered sensation, weakness of the lower extremities, bowel and bladder dysfunction, increased likelihood of hip dislocation, and scoliosis progression. Anesthesia...
carries its own risks.
This narrated 3D animation shows the step-by-step process for removing a brain tumor using a new device called a neuroendoport. It is considered a minimally invasive brain surgery because the neuroendoport device requires a relatively small incision in the skull and underlying dura mater (covering of the brain).
A rhizotomy (É¹aÉªËˆzÉ‘tÉ™mi) is a neurosurgical procedure that selectively severs problematic nerve roots in the spinal cord, most often to relieve the symptoms of neuromuscular conditions such as spastic diplegia and other forms of spastic cerebral palsy. In extreme cases, a rhizotomy may also be considered for a person suffering from severe back pain or a pinched nerve.
The sensory nerve roots are first separated from the motor ones. Identification of the nerve fibers to be cut is then made by means of electrical stimulation. The one(s) producing the pain or other problems are identified in this way, then selectively cut.
Select comparative data from 1999 to 2006 include an 11 percent increase in the number of neurosurgeons with full-time academic appointments and a 6 percent increase in the number of female neurosurgeons.
