Anatomy of Lumbar Spondylosis

Before we study about any disease, we shall thoroughly know about the part of body where the disease takes place. This is known as the anatomy of the disease. Similarly if we go through the anatomy of Lumbar Spondylosis, we will firstly come to know about the vertebral column, its classification and the respective functions.

When we study about the vertebral column we know that vertebral column is a framework of small bones, discs and cartilages which protect the spinal cord and the entire network of nerves present on the back of the body. The bones which fuse and join to each other and make up the vertebral column are referred as the ‘vertebrae’ (sing = vertebra). These vertebrae are vertically positioned and located one on the top of the other. The vertebrae are classified into 5 regions due to their positions where they are located.

The top most region of the spinal cord or the vertebral column which supports the head and the neck is known as the Cervical Vertebrae. This region comprises of seven (7) small bones. These vertebrae support the head and neck and make the nodding movements of the head. After that, arises the Thoracic Vertebrae, which contains twelve (12) bones. These bones make up the rib cage. The next region is the Lumbar Vertebrae which is made of five (5) bones. This is the lower region of the back. It bears the most of the weight of body and muscle articulation. The last two regions are collectively known as the tail spine. These contain 7-8 bones altogether and are known as the Sacrum Vertebrae and the Coccygeal Vertebrae.

As the name directs, Lumbar Spondylosis is a condition in which the Lumbar Vertebrae are degenerated due to slippage of discs and occurrence of osteophytes commonly known as the bone spurs. This disease is mostly common in old-aged people.
