Heading: Traumatology and Orthopedics Article type: Case report
Authors: Stepukhovich S.V., Zaretskov V.V., Arsenievich V.B., Likhachev S.V., Shul'ga A.E., Zaretskov V.V.
Organization:
Summary:

Aim: to demonstrate clinical case of surgical treatment of scoliotic deformity of the spine in a 17-year-old child. It is shown that the correction of sagittal profile achieved by 2-stage intervention and normalized global balance parameters in combination with circular spine anchorage allows providing earliest and fullest rehabilitation of a child.

Biomechanical aspects of circular spondylosynthesis of transitional thoracolumbar spine

Year: 2018, volume 14 Issue: №3 Pages: 560-566
Heading: Traumatology and Orthopedics Article type: Original article
Authors: Likhachev S.V., Zaretskov V.V., Arsenievich V.B., Shul'ga A.E., Shchanitsyn I.N., Skripachenko K.K.
Organization:
Summary:

Aim: to present the potential of biomechanical modeling in individual choice of optimal surgical correction method for transitional thoracolumbar spine injury. Material and Methods. We built solid-base 3-dimensional model of the investigated spine segment in Mimics13 on the basis of CT data of injured thoracolumbar spine. Cage and anchorage models were created in CAE system SolidWorks. Numeric modeling was performed in ANSYS in Workbench medium. We analyzed full movement fields, their maximum values for each model as well as equivalent stress in vertebra and anchorage systems. Results. The analysis of equivalent stress and full movement fields emerging in the models under seven basic types of load revealed the most stable spondylosynthesis model which is circular spine

Long-term results of posterior anchorage of subaxial vertebra in acute unstable trauma

Year: 2018, volume 14 Issue: №3 Pages: 501-504
Heading: Traumatology and Orthopedics Article type: Original article

Summary:

Aim: to study long-term results of posterior anchorage of subaxial vertebra in acute trauma. Material and Methods. We conducted an analysis of long-term results of posterior anchorage of subaxial vertebra in 17 patients with acute unstable trauma which had undergone complex clinical neurological and instrumental investigation, surgical treatment performed from dorsal approach, and the estimation of long-term results in preoperative period. Results. The obtained data indicate the method of transarticular anchorage to be effective and safe and not to have any negative effect on biomechanical properties of cervical spine in the long-term postoperative period. Conclusion. The use of posterior anchorage in acute unstable trauma is most reasonable in subaxial injuries accompagnied by the deformities of medial and posterior spinal columns.

On the issue of surgical reconstruction in complicated aggressive hemangiomas of sacrolumbar transitional spine

Year: 2018, volume 14 Issue: №3 Pages: 487-492
Heading: Traumatology and Orthopedics Article type: Author's opinion
Authors: Arsenievich V.B., Zaretskov V.V., Likhachev S.V., Stepukhovich S.V., Mizyurov S.A., Sadchikov D.D.
Organization: Saratov State Medical University
Summary:

We presented surgical results of complicated aggressive hemangioma treatment in transitional sacrolumbar spine. It has been stated that individual peculiarities of decompressive stabilizing surgery depend on the volume of vertebral lesions and their results improve in the combination with presurgical X-ray therapy.

Decompressive stabilizing operations in the treatment of complicated aggressive hemangiomas of transitional spine.

Year: 2017, volume 13 Issue: №3 Pages: 746-751
Heading: Traumatology and Orthopedics Article type: Original article
Authors: Likhachev S.V., Arsenievich V.B., Salina E.A., Stepukhovich S.V., Norkin A.l., Mizyurov S.A., Zaretskov V.V.
Organization: Saratov State Medical University
Summary:

The aim: to study the efficiency of surgical treatment of complicated aggressive hemangiomas in transitional spine. Material and Methods. Decompressive stabilizing operations were made to 26 patients aged 35-52 years with hemangiomas of vertebral bodies. Individual surgical features varied due to the character and level of the injury. Results. In the experimental patients' group in admission there was neurological deficit of compressional origin associated with the critical values of luminal narrowing due to the epidural component of the neoformation. Stable antalgic effect and decrease in neurological deficit were seen postsurgically. Conclusion. While choosing the surgical option of decompressive stabilizing treatment a surgeon should take into account roentgenomorphometric features of the injured vertebrae. Adequately planned intervention fulfilled with the account of the injury character allows obtaining favorable outcomes as well as LQ improvement, neurological deficit decrease and the elimination of pain syndrome.

Transpedicular fixation in comminuted fractures of bodies of thoracic and lumbar vertebrae

Year: 2014, volume 10 Issue: №3 Pages: 441-446
Heading: Traumatology and Orthopedics Article type: Original article
Authors: Zaretskov V.V. Arsenievich V.B, Likhachev S.V., Shulga A.E., Titova Ju.l..
Organization:
Summary:

Research Objective: improvement of transpedicular fixation technique in cases with spine injuries accompanied by vertebral body splintering. Material and Methods. Transpedicular spondylosynthesis was performed in 52 patients aged 18-49 years with comminuted fractures of thoracic and lumbar vertebral bodies. Individual peculiarities of the operation depended on the character of the injury ascertained during the preoperative examination. Standard roentgenography and computer tomography were used. Results. Lasting antalgic effect was observed in 94,2% of the operated patients. In cases with type A3 fractures according to F. Magerl the rate of the surgical correction of the pathologic posttraumatic kyphotic deformity averages 87%. Injuries classified as type A2, B2 or C2 were the indication for transpedicular os-teosynthesis by advanced techniques. Conclusion. Transpedicular spondylosynthesis is one of the effective methods of treatment of patients with comminuted fractures of thoracic and lumbar vertebral bodies, and the choice of carrying out of the procedure depends on the injury character. In cases with comminuted fractures of type A2, B2, C2 it is reasonable to perform transpedicular spondylosynthesis with introduction of the transpedicular screws into the injured vertebral body, and the technique of their use depends on the injury character.
