Lumbar Spinal Fusion

Lumbar spinal fusion is the procedure which is used for the treatment of lumbar spinal instability.
Indications for Surgery:
  1. Severe pain.
  2. Pain more than 3 weeks, not relieved by medications.

Procedure
Anaesthesia: The surgery is performed under general anaesthesia with the patient lying face down on the operating table.
Surgery: After cleaning the area of surgery thoroughly, the level of surgery is confirmed under X ray machine. An incision is made of about 4-5 cm at the level of surgery. Muscles are retracted to one side by dissection to expose the bone. Pedicle screws are inserted into the bones of the involved spinal level. A small portion of bone is removed (laminotomy or laminectomy) along with the ligaments to enter into the spinal canal and expose the spinal nerves and achieve decompression of the spinal nerves. The screws are connected with help of rods and an interbody cage inserted to restore alignment of the spinal column. The bone which is removed during the surgery in crushed into small pieces and is placed along the rods to induce fusion between the two bones.
