With age, degenerative changes accumulate in the human body and in particular in the spine, the degree of damage to the intervertebral discs, vertebrae, facet joints and ligaments increases, which can lead to compression of nerve roots and severe clinical manifestations.
One of the important problems of vertebral surgery is the treatment of segmental instability, which in turn is one of the pathogenetic stages of the development of degenerative lesions of the spine. To date, the “gold standard” in the treatment of instability is the stabilization of the segment by creating spondylodesis, for which many different surgical techniques have been proposed.
