Confusion regarding mechanisms of injury in the setting of thoracolumbar spinal trauma: a survey of The Spine Trauma Study Group (STSG).

摘要: The Spine Trauma Study Group (STSG) developed the thoracolumbar injury severity score to direct management of spine injuries. original system is based on 3 variables: mechanism as determined by imaging studies, integrity posterior ligamentous complex, and neurologic status patient. Considerable controversy exists among treating physicians in classifying mechanisms. purpose this study was survey STSG case examples related injury. A 2-question regarding mechanisms scoring distributed members STSG. total 27 completed surveys defining Data from these were analyzed using a 2-tailed Fisher exact test chi2 contingency table. Sixty-seven percent preferred definition incorporating complex disruption without vertebral body retropulsion over location axis rotation differentiating flexion-distraction advanced stage flexion-compression injuries, representing statistically significant difference (P=0.0285). There no statistical consensus emphasizing primary secondary patterns. Despite 1 question, there seems be dominating opinion distinguishing Perhaps identifying objective findings studies clinical examination place guessing may allow for more reliable valid classification system.
