[A classification of implants for reconstruction of the anterior and middle supporting columns of the spine].

Objective: The study objective was to classify implants for anterior interbody fusion, depending on their design features and functional capabilities, to optimize the choice of endoprosthesis designs for reconstructive surgery of the spin.

Material And Methods: We analyzed information provided in advertising brochures, annotations, and communications describing the designs of vertebral body endoprostheses. To study the design features of various implants, we selected 25 implant types with the structural designs of major units typical of vertebral body replacement systems.

A telescopic vertebral endoprosthesis for subaxial cervical fusion.

Purpose: The study purpose was to develop an anterior subaxial cervical fusion technique using a new telescopic vertebral graft (VG) construction and to introduce the technique into clinical practice.

Material And Methods: We analyzed existing VG constructions used in anterior interbody fusion at the cervical spine level and developed our own variant of a vertical, cylindrical, telescopic, mesh, vertebral endoprosthesis as well as a technique of its placement to replace bodies of the cervical vertebrae. The technique was used in 11 patients with spinal trauma.
