Instead of an isolated nerve, when the entire spinal cord is pressed from a slip disc, osteophyte (bony overgrowth) or ligamentous overgrowth; this condition is referred to as Cervical Myelopathy. This is a serious condition, which needs to be recognized and addressed as early as possible. Otherwise, it can result in irreversible paralysis.
These patients may complain of tingling or numbness in their hands. They may have difficulty with their balance (can be tested by trying to walk along a straight line. They may find it difficult to perform fine motor activities with their hands (like buttoning their shirt, messaging on a mobile or typing on a computer). Rarely, they may report an electrical sensation going down their body on movement of their neck. They may even report a change in their ability to control their urine or motion.
As this is an irreversible and progressive condition, the treatment for this condition is always surgical. Depending on whether the compression is from front of the neck or behind the neck, decompression can either be done from the front (ACDF or ACDR) or from behind (Cervical Laminectomy with or without fusion or Cervical Laminoplasty).
