Tóm tắt

Eight baseball players developed digital ischemia as a result of repetitive ball impact. Symptoms and signs were coolness, numbness, cyanosis, paleness, and a positive reaction to the digital Allen's test. Seven of the eight players developed digital ischemia between the ages of 16 and 17. Angiograms of four patients with an occluded index digital artery are presented. Thermo- grams of four patients with a cool area of the left index finger are also presented. We investigated the incidence of digital ischemia by administration of a questionnaire. The respondents were 578 players belonging to clubs in junior high schools, high schools, and colleges. No digital ischemia was found in 207 junior high school baseball players. The incidence increased in high school (66 of 299) and college (29 of 72). The probability of developing digital ischemia corresponded to the accumulated playing time. Digital ischemia occurred characteristically in the left index finger.
