A new method for shortsegment multi-rod posterior instrumental fixation of lumbar vertebral body fractures: development of the technology and a clinical case

Abstract

A new method of short segmental multi-rod posterior instrumental fixation of lumbar vertebral body fractures (groups A3 and A4 according to the AO classification) characterized by the combined use of two short transpedicular screws with maximum lateralization of their heads fixing the injured and adjacent vertebrae and two short laminar implants in the form of distractors and contractors installed according to a standard technique with their positioning symmetrically to the spinous processes was developed. If transpedicular fixation of the fractured vertebra is impossible, both laminar systems are installed in the form of staples with circular coverage of the corresponding half-arc of the adjacent vertebrae due to supra- and infralaminar arrangement of standard hooks. The method involves the use of standard vertebrological instruments as well as widely available licensed implants and the classic technique of their installation. A clinical case of surgical treatment of a 27-year-old victim with a comminuted compression fracture (group A3 according to the AO classification) of the 3rd lumbar vertebra is reported. An excellent clinical and radiological result was obtained.
