[Clenched fist injuries from teeth: not to be disregarded].
During the delivery of a blow to the jaw, two men, 33 and 34 years of age, suffered an injury at the level of the right metacarpophalangeal joint in, respectively, the 4th and 3rd digit. In both cases, purulent arthritis and destruction of the MCP-joint developed. Clenched-fist injuries are known for their severe complications such as septic arthritis, osteomyelitis and persistent infection leading to amputation. These complications are due to the easy perforation of the MCP-joint capsule and the fact that the patients do not seek medical treatment until a significant inflammatory process has developed. Exploration of the wound on a flexed hand is crucial to exclude perforation of tendon, joint and bone. The wound should be left open to avoid infections. In case of infections, which can be caused by a variety of aerobic and anaerobic bacteria, the recommended treatment is immediate debridement and administration of broad-spectrum antibiotics.
