title: The baseball bat: a popular mechanism of urban injury.
abstract: From January 1989 through December 1990, 74 patients were admitted to our urban level I trauma center with injuries inflicted by baseball bats. We investigated the demographics and dynamics of injury in these patients by retrospective analysis of the patient's medical record and Trauma Registry data. The average victim was 30 years old. Ninety-two percent of the patients were male, and approximately 89% tested positive for substance abuse. Injury to both the head and body occurred in 80% of our patients, isolated head injury occurred in 42%. Twenty percent suffered injury to the body only. On admission, 7% went directly to the operating suite, 16% were admitted to the trauma ICU, one patient was admitted to the pediatric ICU, and the remainder were admitted to the floor shock/trauma unit. These patients had a length of stay (LOS) that was not significantly different than the LOS for patients with penetrating trauma or the general trauma population. The mean Trauma Score was 13.8 (range, 6-16), and the average Injury Severity Score was 10.5 (range, 1-34). The mortality in our study was 3%. Four percent of the patients were left with some degree of permanent disability. Intentionally inflicted injury is most commonly seen in the thorax and abdomen. In contrast, head injury was evident in 80% of our patients with baseball bat injury. This represents a departure from classic patterns of violent injury.
