Brief summary
Objective. To define the effective surgical management of posttraumatic kyphotic deformities in the thoracic and lumbar spine basing on experimental biomechanical and clinical studies. Experi-mental biomechanical study was performed in 60 spine specimens. Anterior wedge osteotomy and fix-ation of a specimen in a kyphotic position modeled kyphotic deformity. Deformity correction with var-ious instrumentation systems was firstly performed by maximal extension of segments adjacent to ky-phosis-producing block, and carried on after crossing of intervertebral anatomical structures. Clinical study consisted in X-ray and instrumental examinations of 245 patients operated on for thoracic and lumbar spine trauma. The magnitude of true posttraumatic deformity was defined as a difference be-tween measured Cobb angle and mean physiological kyphosis value in the studied spine level. De-formity rigidity, character of spine mobilization at the level of correction and size of posttraumatic de-formity are the most significant factors determining the efficacy of posttraumatic kyphosis correction. The study resulted in defining rational approach to surgical correction of posttraumatic deformities in the thoracic and lumbar spine. Key words kyphotic deformity, thoracic and lumbar spine, correction, mobilization, fixation. (The article in PDF format. For preview need Adobe Acrobat Reader)  Open article in new window
