A severe condition in your spine when one vertebra slips either forward or backward in comparison with the next vertebra is called spondylolisthesis. This condition often leads to a kind of deformity in your spine and can be treated with a number of spinal fusion surgeries. When the vertebra slips forward, the condition is known as anterolisthesis. And when the vertebra slips backward it is known as retrolisthesis.
The spinal canal can also be narrowed due to this condition and in some case the nerve roots that exist can also be compressed due to spondylolisthesis. To recover from this condition, the types of spondylolisthesis surgeries which are available are given below.
Types Of Spondylolisthesis Surgery
Posterolateral Gutter Spine Fusion
In this type of surgery, which is considered the gold standard in spine fusion surgery, a bone graft is placed in the posterolateral section of your spine and it is often considered the most potent of all surgery options available for spondylolisthesis.
It has been historically successful in this ailment. Surgeons administer this surgery option from the back where a midline incision, generally three to six inches long, is made. To take care of this ailment, most surgeons trust this method of surgery.
Transforaminal Lumbar Interbody Fusion (TLIF)
This surgery option is useful when you want to stabilise the vertebra and the disc. A solid bone can be created between the vertebra using this technique and it reduces both pain and nerve irritation. Patients suffering from spondylolisthesis or disc herniations which are recurring find this surgery successful. This is an effective method as the hardware is applied to the spine so that the fusion rate can be enhanced. With the help of a bone graft, the vertebra, both above and beyond can be healed and merged as one long bone.
Posterior Lumbar Interbody Fusion (PLIF)
In PILF, a bone graft is added to the area of the spine where the bone can grow and stop the motion in that part. This generally happens because of a biological response.
The bone grows between toe vertebras and this is how it stops the slipping of the vertebra either forward or backward. In PILF, surgeons use a cage made with allograft bone or PEEK or titanium and this is inserted in the lower back and directly in the hollow of the disc.
Anterior and Posterior Lumbar Fusion
Among the types of spondylolisthesis surgery the Anterior and Posterior Lumbar Fusion is quite popular because of the advantages it offers. It provides a lot of stability as both the front and the back of the spine can be used using this technique. It is particularly suitable for patients suffering from fractures and in the cases when initial fusion does not set up. As a primary technique also this surgery is quite popular among surgeons.
Anterior Lumbar Interbody Fusion (ALIF)
ALIF was first performed in the 1950s to treat lower back pain and though it had non-union rates of 30% – 40% and hence it did not gain immediate favour, it is now used in combination with anterior or posterior fusions.
ALIF is useful and efficient when you have a huge collapse in the disc space and instability. This type of surgery gained popularity with the development of threaded cages in titanium as they had a higher fusion rate.
These types of spondylolisthesis surgery are helpful in treating a severe and painful condition like spondylolisthesis. The most important structure of your body, the spine, can benefit from these surgeries and post surgery you can bid pain goodbye for good.
