EVERYONE on here !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! - OPERATION -
This procedure is not a fix all procedure, but a procedure for helping with neuropathic pain.
Dorsal Root Entry Zone Lesions
The superficial part of the grey matter in the dorsal horn of the spinal cord has a complex of neural networks that are thought to modulate pain pathways. Lesions have been made in the area where the dorsal root enters the spinal cord (dorsal root entry zone) in an attempt to control a variety of pain syndromes. The operation requires a laminectomy to expose the dorsal root entry zone, followed by either a series of radiofrequency coagulations or an incision and diathermy of the area. Dorsal root entry zone lesions have been used for the treatment of a variety of neuropathic pain syndromes but brachial plexus avulsion remains the best indication. It is useful but less effective in peripheral brachial plexus injuries. Other indications include boundary zone pain in spinal cord injury and some peripheral nerve injury pain syndromes. It has been used for post-herpetic pain but the results are variable. The nucleus caudalis, in the lower brainstem and upper spinal cord, forms part of the descending pathway of the trigeminal nerve. Dorsal root entry zone lesions of the nucleus caudalis have been used for the treatment of neuropathic facial pain.
Firstly, the source of the pain in Ruddaga's post needs to be identified.
When the guy gets into his wheelchair, does he get autonomic dysreflexia symptoms, ie, sweating, headaches, red blotches around his neck?
Does he have a healthy appetite?
Is his bowel and bladder management working ok?
Does this pain occur when he sits upright in bed?
There are many questions which need asking and answering before such a procedure as DREZ is performed.
