Lumbar Disc Replacement
Lumbar arthroplasty, also known as total disc replacement (TDR), is a surgical procedure designed to address lumbar disc degeneration by replacing a damaged or degenerated intervertebral disc with an artificial disc. This procedure aims to maintain motion at the affected vertebral segment while relieving pain and preserving spinal function. During lumbar arthroplasty, an incision is made in the abdomen or lower back, depending on the specific approach chosen by the surgeon.
The affected disc is removed, and the artificial disc is implanted in its place. This prosthetic disc is designed to replicate the natural movement and function of a healthy disc, allowing for continued flexibility and motion in the lumbar spine. Lumbar arthroplasty is considered an alternative to lumbar fusion, which involves joining two or more vertebrae together.
The goal of lumbar arthroplasty is to preserve motion at the treated level, potentially reducing the risk of adjacent segment degeneration that can occur after fusion surgery. This procedure is typically recommended for individuals with symptomatic lumbar disc degeneration who have not found relief from conservative treatments.

Conditions Related To Lumbar Disc Replacement
Scoliosis
A scoliosis curve can occur in the thoracic spine, the lumbar spine, or both areas at the same time.
Piriformis Syndrome
Piriformis syndrome occurs when the piriformis muscle, which runs from the lower spine to the top of the thigh bone, presses on the sciatic nerve.
Sciatica
The term sciatica refers to a type of radiculopathy, a pinching or compression of a nerve that occurs in the leg.
SI Joint Dysfunction
The sacroiliac (SI) joints are located where the sacrum (the triangular bone at the base of the spine) meets the iliac bones (the large pelvic bones).
Lumbar Stenosis
Spinal stenosis describes narrowing inside the spinal canal and mainly occurs from a combination of aging and degenerative changes in the spine.
