Study Design
An analysis of volleyball-related trauma was conducted using the
National Electronic Injury Surveillance System (NEISS). The NEISS
database collects information from approximately 100 emergency
departments (EDs) under the United States Consumer Product Safety
Commission and provides data extrapolated to a nationally representative
sample. NEISS data consists of demographics (age, sex, and race),
medical injury information (diagnosis and injury location) and a
description of the event.
