The present article is devoted to the analysis of the results of surgical treatment of degenerative-dystrophic spine diseases using posterior access and polyetheretherketone (PEEK) intervertebral implants. The study included 50 patients who underwent transpedicular fixation with PEEK placement and autograft. Analysis of the results showed a significant reduction in pain syndrome, restoration of intervertebral disc height, and stable fixation of the spinal segments. The mean Visual Analog Scale scores decreased from 7.74 ± 0.9 to 2.04 ± 1.56 in the postoperative period, and the Oswestry Disability Index decreased from 53.86 ± 15.11 to 12.8 ± 6.96, which confirms the improvement of the patients’quality of life. Clinical and radiological data 2 years after surgery demonstrated a high level of fusion, stability of results, and minimal complications. PEEK has shown high efficacy and safety in the surgical treatment of degenerative-dystrophic spine diseases, acting as an alternative to traditional metal implants. Their advantages include a modulus of elasticity close to that of bone tissue, which reduces the risk of adjacent segment syndrome, and X-ray negativity, which simplifies diagnosis. Despite some limitations due to reduced osseointegration, PEEK remains a promising and reliable solution.
