Artificial spine lumbar disc replacement is one of the most advanced surgical procedures. It replaces the worn or degenerated disk in the lower part of the spine with an artificial one made of metal or a combination of metal and plastic.
To elucidate further, this artificial disc replacement is a spine or back surgery to relieve back pain whilst also maintaining a more normal motion than other procedures like Spinal Fusion. The spine is made of bones called vertebrae and in between these bones are discs that work like a cushion to rotate and move without the bones rubbing against each other. The lumbar vertebrae and discs are situated at the bottom of the spine.
Sometimes bones degenerate because of old age, gender, excessive weight or overuse due to high impact sports or strenuous activities causing reduced mobility in the spinal area.
