Abstract
Objective: Analysis of the results of the study of mineral metabolism and bone formation markers in patients with idiopathic scoliosis, depending on the magnitude of the deformity.Material and methods: Based on the retrospective single‑center study in 30 patients diagnosed with scoliosis the preoperative parameters of calcium metabolism (total and ionized calcium, parathyroid hormone, 24‑hour urine calcium), phosphorus, bone formation markers (alkaline phosphatase, osteocalcin, P1NP in the blood), deoxypyridinoline in morning urine, blood levels of 25(OH)D have been analyzed. The patients were divided into 3 groups: with a deformity of 25–40 ° (group 1), 40–60 ° (group 2) and 60–80 ° (group 3) (n = 30). The mean age in all groups was 18.5 ± 4.7.Results: In patients with idiopathic scoliosis, alkaline phosphatase and P1NP significantly exceeded normal values in the first group, which indicated a more high‑turnover type of bone remodeling with a deficient level of 25(OH)D. A higher excretion of deoxypyridinoline and a decrease in phosphorus in blood in patients with a deformity of 60–80 ° suggest a violation of the ratio of the processes of synthesis and resorption in bone tissue.Conclusion: The study of mineral metabolism and all the main markers of bone formation made it possible to obtain a more complete picture of the state of metabolic processes in bone tissue, to obtain reliable data on the effect of some of them on the nature of bone remodeling and the magnitude of spinal deformity.
