STUDY DESIGN: Retrospective cross-sectional study. OBJECTIVES: To investigate the characteristics of posttraumatic symptomatic @entity1644 after @entity1566 ( @entity1566 ). SETTING: Swiss Paraplegic Centre, Nottwil, Switzerland. METHODS: The @entity1 database was screened for @entity1 diagnosed with posttraumatic @entity1644 . Syrinx characteristics were determined on T2-weighted magnetic resonance images. Binary logistic regression analysis was used to investigate the effects of age, injury level, injury severity and syrinx location on early @entity8233 and syrinx extending @entity129 . RESULTS: The data of 138 @entity1 were analyzed. The majority of the @entity1 (78.3%) suffered from motor and sensory complete @entity1566 (American @entity3510 Association Impairment Scale (AIS) A). @entity1644 was diagnosed a median 15.0 years after @entity1566 at a median age of 42 years. The cervical spine was involved in >57% of the @entity1 , and @entity1644 extended over a median seven vertebral levels. Complete @entity1566 (P=0.035) and age (P=0.001) were significant predictors of early syrinx formation. @entity1644 occurred significantly earlier in older (>30 years) @entity1 (P   0.002) and those with complete @entity1566 (P=0.027) compared with younger @entity1 (   30 years) and those with incomplete @entity1566 (AIS B-D), respectively. Age, injury level, injury severity ( @entity73 ) and syrinx location did not have any significant (P>0.9) effect on syrinx extending cranially or syrinx length. CONCLUSIONS: @entity1644 mainly occurs in @entity1 with complete @entity1566 ( @entity73 ) and involves the cervical spine in 6 of the 10 @entity1 . @entity1 with complete @entity1566 and those age >30 years have an increased risk of syrinx formation within 5 years after injury.Spinal Cord advance online publication, 1 December 2015; doi:10.1038/sc.2015.218.
