[Bisegmental anterior interbody spondylodesis, using rigid plates, in surgical treatment of cervical vertebral column traumas and diseases].

Results of surgical treatment of 34 patients, suffering cervical vertebral column traumas and diseases, are analyzed. In all the patients bisegmental anterior interbody spondylodesis was conducted, using cervical rigid plates and vertical cylindrical net implants. The existing and newly obtained information about changes in the radiological indices dynamics while the method application by its authors is presented. The interbody synostosis was achieved in 82.4% patients in 1 yr after the operation. The complications rate while the implants application have constituted 23.3%, and the total rate of complications--29.1%.

[The analysis of changes bioelectrical activity of the muscles of the upper extremities in patients with traumatic deformation of the cervical spine].

The analysis of changes in bioelectrical activity of the muscles of the upper extremities was held with the help of electromyography in 37 patients with traumatic deformation of the cervical spine in order to identify its dependence on the nature of the initial damage, the amount of deformation and the terms of its existence. It was revealed that in the instrumental evaluation of patients with uncomplicated traumatic deformation of the cervical spine in 33.3 % of cases determined subclinical signs of neurological disorders in the form of changes in the bioelectric activity of the muscles of the upper extremities, most often in the DF and CF types. Frequency of manifestation of peripheral neurologic symptoms is possible with all types of traumatic deformation equally. Violation of bioelectric activity of the muscles of the upper extremities may occur at any value of the angular deformation in the sagittal plane and at different terms of its existence.

[Improvement of stabilization technique of cervical vertebrae using cylindrical implants].

The algorithm for cervical interbody stabilization with the use of vertical cylindrical mesh implant was improvement. Implementation of the developed method allows to reduce the load per unit area of bone bodies of recorded vertebrae in contact with the terminal part of the implant, which reduces the risk of loss of correction of the deformity after surgery. Results of surgical treatment of 5 patients for diseases and injuries of the cervical spine show the effectiveness of the method and the possibility of its application in clinical practice.
