Abstract
We present the case of a 6-month-old infant with flexor tenosynovitis of the ring finger after penetration of a splinter in the distal interphalangeal fold. Thorough irrigation and debridement were necessary after ineffective conservative antibiotic treatment of 48 hours. This is the youngest case ever described in literature. Children present differently from adults in terms of route of inoculation and causative pathogens. The Kanavel signs and inflammatory blood markers have a lower sensitivity than in adults. A high index of suspicion is needed because of the poor clinical and biochemical reliability in infants.
