What is Disc Replacement Surgery?
‘Disc Replacement’ is known by many names such as disc prosthesis or spine arthroplasty device or artificial disc which is a type of arthroplasty. This surgical procedure which replaces degenerated intervertebral discs of spine with artificial devices in the lumbar or cervical spine is known as disc replacement surgery. It is an ultimate solution for treating severe & chronic lower back pain or cervical pain caused by degenerative disc disease. This surgery is an alternative to spinal fusion & also for symptomatic disc herniation with associated arm & hand symptoms.
Artificial Disc Replacement Surgery
Artificial disk replacement is a newer surgical procedure designed to relieve lower back pain. In lumbar disc replacement surgery the degenerated or totally worn out disk of spine’s lower portion is replaced with an artificial replacement. This disc is made up of tissue just like cartilage that consists of annulus which is an outer portion & the nucleus which is the inner portion. It is much flexible so as to allow spine to bend. This prosthetic device is fixed between vertebras & into the spine so that it functions like a normal disc restoring mobility.
Artificial disk surgery is divided into two sections –
- Total Disc Replacement
- Disc Nucleus Replacement
After Surgery Benefits Include
- Motion is restored to normal
- Artificial disc performs the same function as original one like absorption of stress
- There is no need of complex bone graft which has a risk of infection transmission
- Adjacent spinal discs won’t have to bear stress in cervical disc replacement
- Patients recover more quickly in ADS than spinal fusion
- Fewer or rare chances of revision surgical procedure
- Fewer chances of device failures
- Patients who undergo cervical disc replacement hardly need a hard collar surgery
- Quick healing time
ADR Surgical Procedure
Patient has to take supine position i.e. lying on the back. During surgery, anesthesia is given & ‘endotracheal’ a breathing tube is placed & patient breathes with the help of ventilator. Antibiotics are given through vein or intravenous. Region which has to be operated is cleansed with cleaning solution. Surgical team maintains a bacteria free environment by wearing sterile attires, gloves& putting surgical drapes.
A transverse or oblique incision which is 3- 8 centimetre is made on the left portion of belly button & abdominal muscles are gently moved. The peritoneal sacis are pulled back to the side because they are large blood vessels. Special retractors are used by the surgeon for visualizing the anterior part of intervertebral disc. Later an X-ray helps to confirm the level of spine.
Then with special surgical instruments (like pituitary rongeur, Kerrisonrongeur, & curettes) intervertebral disc is removed. A distractor instrument restores the normal height of disc & also determines the appropriate size of artificial disc that is to be implanted. Prosthesis is carefully adjusted & placed in the disc space with instrument. To confirm its position whether it’s correct or not, Fluoroscopic x-rays are taken.
Later, sterile water containing antibiotics is used to wash out & clean wound area. Strong sutures are used to close deep fascial layer & subcutaneous layers & special surgical glue is used to close the skin. This leaves minimal scar & require no bandage. Surgery usually takes 3-4 hours which again depends on the number of discs to be replaced.

Cervical Disc Replacement
Damage is most likely to happen at C4-C5, C5-C6, or C6-C7 levels of cervical discs. This damage may occur due to cervical disc herniation or osteophyte (bone spurs) that encroach upon nerve roots. Other is the age factor, after 60 years of age discs begin to collapse & bulge. In cervical disc replacement surgery after the removal of damaged cervical disc in the process of decompressing the nerve root, an artificial disc is inserted between 2 cervical vertebrae. This disc or device adjusts, restores its height & preserves normal motion. This surgery is an alternative to the other technique like bone grafting that eliminates motion at the operated disc space in the neck. After 2-3 days, patients can leave the hospital but should restrict or avoid few routine activities.
Lumbar Disc Replacement
It is a type of back surgery involving replacement of a worn out or degenerated disk of lower portion of spine with medical-grade artificial replacement disc. It relieves 95-97% back pain & acts as an alternative to spinal fusion surgery which connects two vertebrae together in the procedure.
LDR is recommended by doctors if –
- Source of back painis from 1 or 2 disks in the spine
- Patient has no significant joint disease
- Patient has no compression on the nerves
- Patient is not excessively overweight
- Patient has not done any spinal surgery previously
- Patient has noscoliosis or another spinal deformity
Patient has to be in hospital for approximately 3-4 days. As it doesn’t require any bone to heal recovery period is quicker compared to other back surgeries. The lumbar disk replacement surgery reduces the pain but in a gradual manner.
Artificial Spinal Disk Replacement Surgery
This is arthroplasty, which involves removing of worn out inter-vertebral disc in spinal column & replacing it with artificial disc. It treats chronic & severe lower back pain & cervical pain which happens due to worn out disc disease.
Recovery After Artificial Disc Replacement Surgery
Patients are advised to stay back in the hospital for observation for 3-4 days. Doctors may tell patients to stand on feet on very first day after surgery. Within or after a week patients can resume normal activities with few restrictions & after 6-8 weeks they can do whatever work they want to.
Disc Replacement Surgery Success Rate
Success rate in India for disc replacement surgery is high & up to 89-92%. This also depends on the severity of the damaged disc.
