360º pedicle arthrodesis



360° circumferential arthrodesis with artificial disc and pedicle screws to achieve long-lasting stabilization in spines with significant instability.
In many cases, screws are necessary for advanced spondylolisthesis, spondylosis, scoliosis, and many other conditions. However, traditional arthrodeses work very well when combined with discs, as they create a very solid construct. The biggest failure of spinal surgery, which also generates many erroneous myths in this condition, is the placement of screws and rods alone without associating them with discs. This only provides 180° stabilization, and we know from statistics that between 30 and 40% of these surgeries will fail, and patients may continue to experience the same or worse symptoms than before surgery. Therefore, whenever possible, minimally invasive surgeries with disc placement via a lateral or abdominal approach should be sought, as well as hybrid dynamic stabilization without screws. And when necessary, screws should always be placed in conjunction with a disc.

¿Qué es una artrodesis?

When we talk about arthrodesis, we refer to the fixation of several segments of the spine. This involves using pedicle screws associated with rods that can be shaped like the spine.

When is arthrodesis recommended?

Screw arthrodesis is often necessary for conditions such as spondylolisthesis, spondylosis, and scoliosis. It is generally necessary when there is significant instability in certain spinal segments.


They can also work in degenerative disc diseases, provided they are accompanied by an interbody disc.

Why can arthrodesis fail?

It is the most common problem in spinal surgery.



Screw placement without discs fails in approximately 40% of cases. This is because, on the one hand, by severely blocking that segment, it places a significant strain on the adjacent discs. On the other hand, the screws often either break or create looseness and micromovement within the vertebrae, which can be very painful.

Will I lose mobility after arthrodesis?

Patients fear losing mobility in their spine after arthrodesis, although this isn't truly the case. Ninety percent of the work of bending is done by the hips. Therefore, with arthrodesis surgery, the risks are greater due to the looseness caused by the screws and the workload at adjacent levels. That's why we never tire of repeating that arthrodesis, indicated for the right patient after a thorough diagnosis, is a good solution, provided that a cage or interbody disc is inserted.
