The interbody cage is used to replace the intervertebral space after disc removal. The cage is placed between the vertebral bodies, which fills the height of the disc lumen and expands the space through which the nerve endings exit. This eliminates their tightness and pain. Indications for cage implantation are stabilization of the lumbar spine after removal of the intervertebral disc, spinal deformities, injuries, destructive changes, as well as degenerative processes. The implant is made in the form of a support with a special sliding mechanism that allows you to intraoperatively adjust the height of the cage from 8 mm to 11 mm. The surfaces in contact with the vertebrae have a sufficient area and are made with a notch, which increases the stability of the position and reduces the possibility of migration. The rounded contours of the cage facilitate its introduction into the intervertebral space. The cage is made of titanium alloy, which provides bioinertness of the structure. The effectiveness of the cage for spondylodesis is proven by the fact that this implant provides a low risk of complications, leads to less severe pain, stabilization of the spine, reduces the duration of the rehabilitation period due to less tissue trauma during surgery.
