Back

The spine, also called the back bone, plays a vital role in stability, smooth movement and protection of the delicate spinal cord. It is made up of bony segments called vertebra with fibrous tissue called intervertebral discs between them. The vertebra and discs form the spinal column from the head to the pelvis, giving symmetry and support to the body.

A single vertebra is made up of two parts, the front portion is called the body and the back portion is referred to as the vertebral or neural arch. The body is cylindrical in shape, strong and stable. Two strong pedicle bones join the vertebral arch to the body of the vertebrae.

The laminae of the vertebra can be described as a pair of flat arched bones that form a component of the vertebral arch. The transverse processes spread out from the side of the pedicles, like wings, and help to anchor the surrounding muscle to the vertebral arch. The spinous process forms a steeple at the apex of the laminae, and is the part of our spine that is felt directly under the skin.

The spinal canal is formed by the placement of single vertebral foramina, one on top of the other, to form a canal. The purpose of the canal is to create a bony casing from the head to the lower back through which the spinal cord passes.

The spine can be divided into 4 parts: cervical (neck area), thoracic (mid-back), lumbar and sacral region (low back area). The thoracic spine has an outward curve called kyphosis, whereas the lumbar spine has a slightly inward curve, which is called lordosis.

Back Anatomy
Conditions
  •  
    Disc Herniation Herniated disc is a condition in which the outer fibers (annulus) of the intervertebral disc are damaged causing the soft inner material
     
  •  
    Degenerative Disc Disease Degenerative Disc Disease is a condition caused by wear and tear on the discs between the vertebrae causing them to lose their cushioning ability.
     
  •  
    Degenerative Disc Disease Spinal stenosis is the compression of spinal nerves caused by narrowing of spinal canal and it is one of the common causes of low back pain.
     
Surgical Procedures
  •  
    Spinal fusion Spinal fusion is the surgical technique of combining two or more vertebrae.
     
  •  
    Laminectomy Lumbar laminectomy, also known as decompression laminectomy, is a spinal surgery done to relieve excess pressure on the spinal nerve(s) in the lumbar (low back) region.
     
  •  
    Endoscopic Discectomy Endoscopic Discectomy is a minimally invasive procedure for the treatment of herniated disc, lower back and leg pain.
     
  •  
    Lumbar artificial disc replacements Lumbar artificial disc replacement is a surgical method of replacing the diseased or damaged intervertebral discs of the spinal column
