[Hand injuries resulting from high-pressure injection: lesions specific to industrial oil].
Nineteen cases of high pressure injection injuries in the hand were treated between 1973 and 1998. Same surgical treatment plan was followed in all cases: excision of the penetration point, irrigation, debridement and synovectomy if opening of the flexor sheath was noted, and skin closure to allow early mobilisation. All cases concerned men, work injuries, and volar aspect of the hand. The elapsed time between injection and initial surgery ranged from 1 hour to 1 month with a mean of 6.5 days. Eighteen patients out of 19 were reviewed with a mean follow up of 12 years. In 11/19 cases, (58%) oil was injected. The results of oil injection cases have been analysed: the quantity of oil and the preoperative delay (if more ten hours) are associated with poor functional results or complications. Two amputations, two cases of skin necrosis at the injection point, and one case of infection are reported. One case of oleoma of the thumb is described. The specificity of injuries by industrial oil under pressure must be known: paint or white spirit are more toxic than oil which was in all cases injected in the dominant hand (no high pressure injection tool but a defect in the pipe). An important inflammatory reaction with functional sequelae is caused by foreign bodies in oil. Extraction of oil off the injured tissues is difficult because oil is not visible. A specific information is necessary for farmers and truck driver, very exposed population.
