Transitional lumbosacral vertebrae

Abstract

Transitional lumbosacral vertebrae in the form of SI lumbarization and LV sacralization are classified as spinal anomalies. 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.

The Use Carbon Composite Material For Replacement of Postresection Bone Defects

“…The use of composite materials is a whole direction in clinical traumatology [15 -23]. In parallel with other alternative studies, the direction of using carbon materials for bone void replacement is developing [11,12,24]. The choice among these materials is also differentiated for different patient groups.…”

“…We have not seen any reports on the use of such materials in pediatric practice. The advantage of implants made from this material is that its mechanical properties are close to those of native bone, the material is inert to living tissue, but no one has taken advantage of the possibility of using these already proven composite materials in children [5,12]. Our experience with the use of highly porous honeycomb carbon material in children has demonstrated its high efficacy, with clear boundaries for the use of this material in young patients [26].…”

“…The successful use of porous carbon in adult traumatology and orthopedics was the result of in-depth research and numerous studies. In clinical use, this material has proven itself well, which was sufficient reason to introduce this technology in children with a certain degree of caution and under mandatory dynamic monitoring [5,12,13,14].…”
