EVALUATION OF THE BIOMECHANICS OF THE VERTEBRAL-MOTION SEGMENT IN PATIENTS WITH MULTIPLE HERNIAS OF THE CERVICAL SPINE OPERATED USING THE METHOD OF PUNCTURE LASER MICRODISCECTOMY

Introduction. According to the literature, the stability of the vertebral-motion segment by 40–60% is provided by the intervertebral disc . Disruption of the structure of the intervertebral disc leads to a disruption in the stability of the vertebral-motion segment. Puncture laser microdiscectomy opened the era of outpatient surgery in the treatment of patients with discogenic neurocompression syndromes. Regression of pain syndrome in discogenic spine syndromes occurs as a result of the creation of decompression, derepression, and microfenestration of the intervertebral disc. Performing laser vaporization also stimulates the development of fibrosis in the intervertebral disc, and subsequently contribute to the stabilization of the vertebral-motion segment.

The aim of the study. To evaluate the biomechanics of the vertebral-motion segment in patients with discogenic neurocompression syndromes, caused by multiple hernias of the cervical spine, operated by the method of puncture laser microdiscectomy.

Case presentation. We analyzed the basic parameters of the vertebral-motion segment in 55 patients operated in the period from 1997 to 2016, for multiple hernias of the cervical spine .

The results of our study indicate a lack of biomechanical changes in the operated vertebral- motion segment, at different times of observation. Thus, the method of puncture laser microdiscectomy is a minimally invasive method of surgical treatment of patients with multiple hernias of the cervical spine, and does not cause a change in biomechanics at the level of the operated vertebral-motion segment.

Conclusions. The method of puncture laser microdiscectomy is a minimally invasive method of surgical treatment of patients with multiple hernias of the cervical spine, and does not cause a change in biomechanics at the level of the operated vertebral-motion segment.
