title: Hand infections secondary to fish bone injuries.
abstract: Hand injuries associated with fish bones and fin spines are not common but can cause morbidity out of proportion to the original injury. This is because such injuries often leave residual fragments of foreign organic matter in the tissues, leading to troublesome secondary infections. This report details 1 year's experience with nine hand infections after fish bone injury in a busy regional hand surgery referral centre. There were five males and four females with an average age of 45 years. Radiographs taken on presentation in five patients revealed a radiolucent foreign body in only two patients. Two patients presented with a flexor tendon sheath infection, three with a pulp space infection, one with infection of the hypothenar space, one with a subungual infection, one with cellulitis of the dorsum of the hand and one with an abscess on the dorsum of the hand. Antibiotics were prescribed for six patients and all patients except the one with cellulitis of his hand underwent surgical débridement. A single surgical procedure was adequate in five patients. One patient with a hypothenar space infection only had the foreign body removed during the third surgical débridement. The two patients with flexor tendon sheath infections required ray amputation. Fish bones cause a number of different infections in the hand. A foreign body should always be sought even if not present on the radiograph. Antibiotic selection should be tailored to eradicate the causative organism.
