What is a selective rear rhizotomy?
Selective rear rhizotomy is a surgery to relieve muscle tightness or spasticity that occurs in patients with brain palsy. During this procedure, the back nerve roots in the lower area of the spinal cord are identified and cut, which contribute to muscle spasticity. Prevention of excess signals from these nerves can allow the patient to control muscle movement and improve the quality of life. This injury is usually permanent and may disrupt the electrical signals that are sent back and forth between the brain and the muscles. Two types of nerve fibers must work together to send and receive signals to and from the muscles: sensory fibers send signals from the muscle to the spinal cord, while the engine fibers of the nerve fibers send signals from the brain to the muscle.
Motor nerve fibers in brain palsy patients do not work rightly, leading to an increase in signals from sensory nerves on the spinal cord. This increase causes muscle tightness, which in turn causes patients to have poor muscle coordination. To dIsposed are various forms of surgical and physical therapy that help patients regain muscle control. Selective rear rhizotomy is once a surgical therapeutic option that can reduce signals from sensory nerve fibers and improve the patient's mobility.
Selective rear rhizotomy is usually performed in children aged two to five years. Patients must undergo a number of tests before surgery to determine the range of muscle spasticity. Once the patient is a candidate, the child can be admitted to the hospital. Surgery is performed while the patient is under general anesthesia.
For selective rear rhizotomy, surgeon is a cut of Thdrny skin of the lower back. One or more vertebrae in the lumbar or sacral area of the spine is exposed. Lamin removal, bone process on vertebrae, must be done to detect all nerve roots. The roots of the sensory nerve andThe roots of the motor nerve are separated from each other and the roots of the engine are covered to ensure that they are not disturbed.
Sensory roots are stimulated by electric probes to determine which nerves cause spasticity in the patient. These roots are then interrupted so that the signals can no longer travel along these nerves. It is a permanent surgery, so the surgeon must carefully decide which nerves to reduce. Once the nerves are reduced, the patient may experience muscle weakness, even if the tightness has disappeared. The muscle strength can be re -created through a strict physical therapy program and the patient should have more control over muscle movement.
