Disc replacement surgery consists of a surgical replacement with a joint segment prosthesis, that is, the intervertebral disc.
In this article we are going to explain what are the options that we currently have available in the case of finding ourselves in front of a patient who has back pain because he has a diseased disc that does not respond to conservative treatment with medications and we have to think about operating.
There are different options to consider that we detail below, these are:
Classic option, spinal arthrodesis
Spinal arthrodesis (fusion) is to date the preferred technique for the treatment of spinal pathology. We can perform open surgery, or percutaneously (keyhole with camera), and using TLIF and XLIF posterior and lateral approaches respectively.
We proceed with a fixation that allows us to control the pain, but the patient loses mobility.
A promising technique: Disc replacement surgery
The second option is a promising technique that involves replacing the disc with a prosthesis that simulates the movement of the original disc.
With this option the patient’s pain is controlled and he continues to have mobility.
Analyzing the surgical tradition of surgery to joints, when a knee, a hip or a shoulder degenerates and provides pain, they are operated and replaced with prostheses that reproduce the original joint movement. We rarely begin treatment with a fixation of the joint. We should also remember this concept in the spine which is a mobile structure.
Advantages of disc replacement surgery
The advantages for the patient are remarkably beneficial and appreciable.
For Disc replacement surgery, an anterior approach to the spine is necessary.The vertebral musculature is very important in lumbar stability. Not damaging it makes the postoperative pain and hospital stay less for the patient. By accessing through a lumbar anterior route (through the abdomen), the posterior musculature remains intact.
Regarding the implant, since it is a prosthesis that is not fixed and that faithfully reproduces the mobility of the original disc, the patient will continue to have mobility in his spine, minimising the risk of relapse of spinal injuries due to deterioration of the level adjacent to a fixed space.
Disc replacement surgery is performed at the London Spine Unit in a first-class hospital environment with a complete team that includes a specialist disc replacement surgeon, an experienced anesthesiologist and a highly qualified nursing team.
Indications
This type of surgical intervention is aimed at patients with degenerative disc disease with young age, with physically demanding jobs, military, police, firefighters. Also for patients without obesity, and without bulky disc herniation or posterior root compression.
Patients with bulky disc hernias who present with severe radiculopathy are not suitable candidates for this intervention. Also those with highly evolved degenerative disease are better candidates for posterior fixation.
