RESUMO
A decrease in bone mineral density is the most common cause of complications in the long-term period of postoperative observation. The purpose of the study was to study the prevalence of vitamin D deficiency in elderly patients who are planning to perform spine surgical procedures. The study included 63 elderly patients hospitalized in spine surgical clinics in order to perform planned surgical procedures for degenerative diseases of the cervical and lumbar spine (34 women, 29 men, average age 63,6±3,2 years). The construction of a binary logistic regression model showed that the following parameters are reliably associated with a deficiency of the active form of vitamin D in patients who are planning to perform surgical interventions on the spine: male gender, age (over 65 years), body mass index (more than 30 kg/m2) and diabetes. The identification of risk factors associated with the presence of vitamin D deficiency and the study of markers of bone metabolism represent the most important stage in the preoperative preparation of older patients who are planning to perform surgical interventions on the spine.
