APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The surgeon removes the bony arch of the posterior part of the vertebra (lamina) to ease 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 done at the same time.

Detailed explanation-2: -A laminectomy is a surgical incision into the backbone to obtain access to the spinal cord. One of the most common reasons for laminectomy is a prolapsed or herniated intervertebral disc. Occasionally, the operation doesn’t work and the original symptoms remain.

Detailed explanation-3: -Posterior laminectomy is an effective surgery for lumbar and cervical stenosis from any cause, but particularly when the spinal cord is being compressed from the back by infolding or abnormally enlarged ligamentum flavum, a ligament which runs down the inside of the roof of the spinal canal.

Detailed explanation-4: -During a laminectomy, a surgeon takes out most or all of the lamina. This is considered major surgery and typically isn’t performed unless more conservative treatment options have failed. Laminectomy may be performed on the cervical, lumbar, sacral, or thoracic spine.
