Diskectomy

Spinal microdiskectomy; Microdecompression; Laminotomy; Disk removal; Spine surgery - diskectomy; Discectomy

Diskectomy is surgery to remove all or part of the cushion that helps support part of your spinal column. These cushions are called disks, and they separate your spinal bones (vertebrae).

Herniated nucleus pulposis

Herniated nucleus pulposus is a condition in which part or all of the soft, gelatinous central portion of an intervertebral disk is forced through a weakened part of the disk, resulting in back pain and nerve root irritation.

Skeletal spine

The spine is divided into several sections. The cervical vertebrae make up the neck. The thoracic vertebrae comprise the chest section and have ribs attached. The lumbar vertebrae are the remaining vertebrae below the last thoracic bone and the top of the sacrum. The sacral vertebrae are caged within the bones of the pelvis, and the coccyx represents the terminal vertebrae or vestigial tail.

Spine supporting structures

The spine is surrounded by many muscles and ligaments which give it great strength and flexibility. If these muscles or ligaments become damaged, back pain results.

Cauda equina

The spinal cord ends in the lumbar area and continues through the vertebral canal as spinal nerves. Because of its resemblance to a horses tail, the collection of these nerves at the end of the spinal cord is called the cauda equina. These nerves send and receive messages to and from the lower limbs and pelvic organs.

Spinal stenosis

Spinal stenosis is a narrowing of the lumbar or cervical spinal canal. The narrowing can cause compression on nerve roots resulting in pain or weakness of the legs. Medications or steroid injections are often administered to reduce inflammation. If the pain is persistent and does not respond to these conservative measures, surgery is considered to relieve the pressure on the nerves.

Microdiskectomy - series

The appearance of a normal intervertebral disk is compared to a herniated disk.
