A laminectomy consists of the resection of the posterior arch of a vertebra to relieve pressure on the spinal nerves and spinal cord caused by injury or by the appearance of a herniated disc, spinal stenosis or a tumor.
The procedure is performed through an incision in the lumbar area through which the surgeon removes the “foil”, the bony arch at the back of the vertebra that is pressing on the nerve. He may also remove bony spurs and part or all of the intervertebral disc.
The procedure can be performed under general or spinal anesthesia and lasts between one and three hours. Patients should be hospitalised about three days after surgery.
BEFORE THE PROCEDURE
Patients should undergo a preliminary test to evaluate the specific characteristics of their intervention.
Furthermore, they must undergo a standard preoperative study that includes blood tests, electrocardiogram, etc.
Also, if they have any chronic illness or regularly take medications, especially anticoagulants, they should inform the surgeon before surgery.
AFTER THE PROCEDURE:
For some time, patients should wear a lumbar corset and compression stockings.
Patients should walk for a while every day and avoid sitting or being immobile for a long time. They need to be very careful with their movements to avoid damage in the wound or the operated area. They must avoid actions like driving, bending or climbing stairs for a few days.
