The treatment of cervical spine dysfunctions is mainly done through two procedures - Decompression and Fusion.
De-compression with fusion cervical spine surgery entails surgically removing the tissues which are pressing against the spinal cord or the nerves resulting in pain or other problems. The approach used for the surgery can be different depending where the tissue is being compressed. The approach used can be from the front (anterior) or back (posterior) of the spine.
There are seven steps to the procedure. The operation generally takes 1 to 3 hours.
The patient is anesthetised and prepared for procedure. Incisions of 2-inch length are made on right side or left side of the neck. The way is paved by retracting and moving muscles, oesophagus, trachea and other structures anatomically in the way to aid in the instrumentation for the procedure.
The damaged disc is located with the help of a fluoroscope and a thin needle is inserted to locate the damaged disc. The surgical instruments are introduced into the space to retract the adjacent discs and spread them apart.
The damaged disc, which is the reason for the pain, is removed thus decompressing the nerve. Bone spurs compressing the nerves are removed and the foramen carrying the spinal nerve is enlarged with a procedure known as foraminotomy.
The spinal cord is decompressed by removal of disc annulus and nucleus.
The preparations are then done for bone graft fusion. The bone graft is properly shaped and introduced into the space between the vertebrae. The graft is kept in place with metal plates and screws.
Instead of fusion or graft, an artificial disc replacement into the disc space can also be done. The incisions can then be closed and dressed.
