In the domestic medical literature, there are few publications devoted to these pathological conditions. In the course of a study of the available literature on the problem of transitional lumbosacral vertebrae, it was found that the frequency of cases of transitional lumbosacral vertebrae diagnosis ranges from 4 to 30% of clinical cases. The share of patients with lumbar vertebrae accounts for an average of 40% of cases, the share of patients with sacralization of the vertebrae is 60% of clinical observations. Mutations in the Hox gene are considered to be the trigger for the development of pathology, and pain is usually the leading clinical symptom. Plain radiography, computed tomography and magnetic resonance imaging are used to diagnose the pathology. Radiation imaging of the entire spine is required to eliminate errors in vertebrae counting. The type of pathology is determined using various classifications. As conservative therapeutic agents, drug blockades applying anesthetics and hormonal drugs are used. The arsenal of surgical interventions includes resection of the enlarged transverse process of the supracacral vertebra, decompression of stenotic intervertebral foramina, impulsive radiofrequency ablation, and posterior fusion. Measures for the prevention of pathology are not currently developed.</p>transitional lumbosacral vertebraeSI lumbarizationLV sacralizationreviewпереходные пояснично-крестцовые позвонкилюмбализация позвонка SIсакрализация позвонка LVобзор[Holm EK, Bunger C, Foldager CB.
