Minimally invasive lumbar arthrodesis (MISS)

The term arthrodesis refers to blocking a joint. This is necessary in some diseases of the spine, the most frequent of them is "spondylolisthesis", which is the displacement of one vertebra over another, creating an abnormal shear movement in the joint that causes the pain.

Minimally invasive fusion consists of blocking the affected joint with 2 mechanisms:

• Fastening with screws in both vertebrae, they are introduced percutaneously, that is, through small incisions.
• The intervertebral disc is removed and in its place a device is implanted that maintains the space and favors the formation of bone bridges between both vertebrae, this procedure is performed using tubular workports, similar to that described in lumbar microdiscectomy or MISS lumbar laminectomy.

Finally, this procedure resolves the "spondylolisthesis" and "canal stenosis" when present, using a minimally invasive technique with a faster and less painful recovery than traditional techniques.
