Spine trauma due to diving: Main features and short-term neurological outcome

Abstract

Study design:This is a retrospective study.Objectives:The aim of this study is to examine the main features and short-term neurological outcomes associated with injuries to the spine due to diving into water in a Latin American country.Setting:Salvador, Brazil.Patient sample:A total of 1324 subjects were admitted with spinal trauma between 1991 and 2006 (inclusive). Subjects aged between 14 and 65 years who sustained diving injuries corresponded to 10.6% (N=140) of the cases.Outcome measures:Neurological status was determined by the Frankel Functional Scale (FFS) on admission and discharge. The FFS was secondarily converted to the American Spinal Injury Association impairment scale.Methods:This study is a patient record database review that examines demographic and injury-related characteristics, details of hospital treatment and neurological status at the time of discharge.Results:Males (N=129) outnumbered females (N=11) in a proportion of 12:1 (mean age: 28.62 years). The cervical spine region was the most affected area (92.1%) and 45% of the cases presented with tetraplegia. On admission, neurologically complete lesions accounted for 32.1% of the overall cases and 45.7% were neurologically intact. The mean length of stay (7.7 weeks) did not differ with regard to treatment option (P=0.83). During hospitalization, patients with incomplete neurological impairment had shorter lengths of stay and showed more neurological improvement than those with complete lesions (P=0.26 and 64.5 versus 2.2%, P<0.0001).Conclusion:Diving spine injuries have a high tetraplegia rate. Neurological recovery and shorter length of stay are associated with incomplete lesions. © 2011 International Spinal Cord Society All rights reserved.
