Spinal fractures associated with aquatic accidents

Abstract

Study design: Retrospective observational study.

Objective: The purpose of this study was to evaluate the prevalence of aquatic spine injuries presenting to a single academic level 1 trauma center.

Background: Aquatic and high-speed watercraft related accidents are associated with drownings, traumatic brain injuries, infections, extremity fractures, and spinal injury. Few prior studies have evaluated the association of aquatic accidents and spine injuries.

Methods: A prospectively collected database of patients involved in aquatic accidents presenting to a single level 1 trauma center in Miami, Florida between February 7, 1999, and December 30, 2020, was reviewed for patients who sustained spinal fractures. Baseline demographics along with accident and injury characteristics were obtained and statistical analysis was performed.

Results: Of 498 total patients admitted following an aquatic accident, 83 (16.7 %) patients sustained a spinal fracture. Non-locals were more likely to require spine surgery compared to locals (80.8 % versus 19.2 %, p < 0.001). The most common MOI was boating or Personal Watercraft (PWC) accident (33 patients, 39.8 %), followed by shallow water dive (SWD; 20 patients, 24.1 %), fall/ejection (FE; 16 patients, 19.3 %), and direct collision (DC; 14 patients, 16.9 %). Operative spine injuries were significantly associated with subaxial cervical spine injuries (p < 0.001) and Shallow Water Dive mechanism (p < 0.001).

Conclusion: Mechanism-dependent, thoracic and lumbar injuries are common in boating and personal watercraft accidents, while operative subaxial cervical spine injuries are common in shallow water dives. Additional research is needed to enhance safety measures, policies, and overall awareness of aquatic activities.
