BACK PAIN AND SPINE SURGERY

Episodes of back pain may be acute, sub-acute, or chronic depending on the duration. The pain may be characterized as a dull ache, shooting or piercing pain, or a burning sensation. The pain may radiate into the arms and hands as well as the legs or feet, and may include paresthesia (tingling with no apparent cause), weakness or numbness in the legs and arms. The anatomic classification of back pain follows the segments of the spine: neck pain (cervical), middle back pain (thoracic), lower back pain (lumbar) or coccydynia (tailbone or sacral pain) with the lumbar vertebrae area most common for pain.

The pain may originate from the muscles, nerves, bones, joints or other structures in the vertebral column (spine). Internal structures such as the gallbladder and pancreas may also cause referred pain in the back.

Back pain is common with about nine out of ten adults experiencing it at some point in their life, and five out of ten working adults having it every year. However, it is rare for it to be permanently disabling, and in most cases of herniated disks and stenosis, rest, injections or surgery have similar general pain resolution outcomes on average after one year.




SPINE SURGERIES

Surgery may sometimes be appropriate for people with:

  •       Lumbar disc herniation or degenerative disc disease
  •        Lumbar spinal stenosis from lumbar disc herniation, degenerative joint disease
  •       Scoliosis
  •        Compression fracture

    Surgery is usually the last resort in the treatment of back pain. It is usually only recommended if all other treatment options have been tried or in an emergency situation.

    The main procedures used in back pain surgery are discetomies, spinal fusions, laminectomies, removal of tumors, and vertebroplasties.

    here are different types of surgical procedures that are used in treating various conditions causing back pain. Nerve decompression, fusion of body segments and deformity correction surgeries are examples. The first type of surgery is primarily performed in older patients who suffer from conditions causing nerve irritation or nerve damage. Fusion of bony segments is also referred to as a spinal fusion, and it is a procedure used to fuse together two or more bony fragments with the help of metalwork. The latter type of surgery is normally performed to correct congenital deformities or those that were caused by a traumatic fracture. In some cases, correction of deformities involves removing bony fragments or providing stability provision for the spine. Another procedure to repair common intervertebral disc lesions which may offer rapid recovery (just a few days) involves the simple removal of the fibrous nucleus of the affected intervertebral disc.

    A discectomy is performed when the intervertebral disc have herniated or torn. It involves removing the protruding disc, either a portion of it or all of it, that is placing pressure on the nerve root. The disc material which is putting pressure on the nerve is removed through a small incision that is made over that particular disc. The recovery period after this procedure does not last longer than 6 weeks. The type of procedure in which the bony fragments are removed through an endoscope is called percutaneous disc removal. Microdiscetomies may be performed as a variation of standard discetomies in which a magnifier is used to provide the advantage of a smaller incision, thus a shorter recovery process.

    Spinal fusions are performed in cases in which the patient has had the entire disc removed or when another condition has caused the vertebrae to become unstable. The procedure consists in uniting two or more vertebrae by using bone grafts and metalwork to provide more strength for the healing bone. Recovery after spinal fusion may take up to one year, depending greatly on the age of the patient, the reason why surgery has been performed and how many bony segments needed to be fused.

    In cases of spinal stenosis and disc herniation, a laminectomy can be performed. During this procedure, pressure on the nerves is reduced, thereby relieving some pain. A specifically designed exercise program during recovery can increase functional status and decrease low back pain as compared to the common recommendation to "stay active".

    Back surgery can be performed to prevent the growth of benign and malignant tumors. In the first case, surgery has the goal of relieving the pressure from the nerves which is caused by a benign growth, whereas in the latter the procedure is aimed to prevent the spread of cancer to other areas of the body. Recovery depends on the type of tumor that is being removed, the health status of the patient and the size of the tumor.
