The efficiency of using individual 3D models of the spine in decompressive-stabilizing operations on the lumbosacral spine

SUBSTANTIATION. A detailed study of the individual anatomy of the spine plays a key role in preoperative planning. To achieve this task, there is a growing interest in the use of individual 3D models of the spine in world practice. Regardless of the positive reviews about the use of individual biomodels of the spine, the question of scientific substantiation of the advantages of the technique remains open. In this regard, we consider it appropriate to conduct research on common typical pathological processes, such as degenerative lesions of the spine.

THE PURPOSE – the evaluation the efficiency of using an individual 3D model of the spine when performing transforaminal spinal fusion surgery in the lumbar region, depending on the individual experience of the surgeon.

METHODS. The study evaluated the effectiveness of using 3D models of the spine when performing a typical decompression-stabilizing operation using the TLIF technique in the lumbosacral region by a more experienced surgeon (more than 150 similar operations) and by a surgeon with isolated cases of performing similar independent operations. The results were evaluated on the basis of the criteria for the safety of implantation according to the Raneyama and AbulKasim methods, the frequency of repeated operations, the number of X-rays performed during the operation, the time of the operation and its individual stages. The obtained data were compared between groups and between surgeons.

RESULTS. The use of individual 3D models of the spine during transforaminal spinal fusion operations in the lumbar spine increased the safety of implantation for both surgeons, but the significance of the differences was greater for a surgeon with little experience. The use of an individual 3D model reduced the operation time and reduced the risks of repeated operations associated with screw positions. To a greater extent, this tendency was observed for beginner surgeons.

CONCLUSION. The using of individual 3D models of the spine in typical decompression-stabilizing operations on the lumbosacral spine is a useful tool for perioperative planning, which increases the safety of implantation, reduces the time of individual stages of the operation and radiation load.
