A laminectomy is a surgical procedure in which a portion of the bony arch, or lamina, on the dorsal surface of a vertebra, is removed. It is done to relieve back pain and pressure on the nerve roots, that has not been helped by more conservative treatments, as in Herniated disc, Spinal stenosis, injury, Cauda Equina Syndrome, etc.
PROCEDURE
Under general or spinal anaesthesia, an incision is given over the selected vertebra. The muscles and fatty tissue overlying the spine are retracted and the lamina (bony arch of the posterior part of the vertebra) is removed to relieve the pressure on the nerves in the area. This may involve removing bone spurs or growths, or removing all or part of a disk. In some cases, spinal fusion may be performed at the same time, to stabilize the spine. The incision is then closed in layers.
DURATION
The entire procedure takes one to three hours. Hospital stay of one to three days may be needed.
RECOVERY
Physiotherapy to improve strength and flexibility is advised. Certain activities like bending, stooping, lifting, long car rides, etc are to be avoided for few weeks. Routine activities may be resumed in two to six weeks.
