High-pressure injection injuries of the hand

High pressure injection trauma to the upper extremity is a rare but potentially limb-threatening injury. The index finger on the non-dominant hand of young male workers is most commonly involved. Injected materials include paint, grease and diesel oil. Prompt recognition and initiation of treatment is necessary if a disastrous outcome is to be avoided. Primary treatment consists of surgical decompression and debridement. Amputation may be necessary. With early aggressive treatment, satisfactory results can be obtained. The use of high-pressure devices in industry has resulted in an unusual but potentially limb-threatening injury to the upper extremity known as the "high-pressure injection injury." This injury is a surgical emergency that demands prompt diagnosis and treatment if a disastrous outcome is to be avoided. The purpose of this paper is to present our recent experience and review the clinical features, evaluation and treatment principles.
