Abstract

Hand injuries caused by the injection of grease under pressure have been previously reported. Smith1 presented the case of a mechanic who accidentally injected grease under 7,000 pounds of pressure into the volar aspect of the base of the left index finger.

The finger became numb immediately and 4 cc. of thick grease could be expressed from the small wound of entry. The next day the hand became swollen and intensely painful. Under gas-oxygen anesthesia, lateral incisions through the pulp along the middle and proximal phalanges were made and 15 cc. of grease was expressed. Several days later the hand was washed with ether in an attempt to wash out the grease. On the ninth day the finger was so gangrenous that a disarticulation was performed and 45 cc. of grease was milked down from the palm and wrist. The wound eventually healed.
