UNASSIGNED: The aim of this study is to determine if thoracolumbar vertebral body collapse or canal compromise (CC) is associated with reposition of bone fragment. We retrospective review medical charts of @entity1 with thoracolumbar burst @entity174 from July 2010 to September 2013. The @entity174 were classified according to the Arbeit Fuer Osteoosynthese (AO) classification system. Neurological status was classified according to American @entity3510 Association (ASIA). @entity1 were divided into two groups (reposition group and non-reposition group) according to whether the bone fragments were reposition or non-reposition after surgery. Mimics measured @entity17323 ( @entity17323 ), @entity5562 ( @entity5562 ), @entity1513 ( @entity1513 ) and @entity2850 ratio (AVBCR), middle vertebral body compression ratio (MVBCR), posterior vertebral body compression ratio (PVBCR), and @entity17323 compression ratio (MSDCR) on the preoperative CT image. The results indicated that 55 @entity1 were included in the study. There are 35 @entity1 with reposition of bone fragment and 20 @entity1 with non-reposition of bone fragment after surgery. There were significant difference on @entity17323 (t = 3.258, P = 0.002), @entity5562 (t = 2.197, P = 0.032), AVBCR (t = -2.063, P = 0.044), MVBCR (t = -2.526, P = 0.015), PVBCR (t = -2.211, P = 0.031), MSDCR (t = -4.975, P = 0.000) between two groups before surgery. There was a significant correlation between reposition of bone fragment and AO classification (OR = 5.251, P = 0.022), and MSDCR (OR = 7.366, P = 0.007). There was no significant correlation between reposition and AVBCR, MVBCR, PVBCR, @entity1513 , @entity17323 and @entity5562 . In conclusion, this study indicates that AO classification and MSDCR are predictors of reposition of bone fragment.
