High-pressure injection injuries of the hand in a Chinese population.

We performed a retrospective review of 28 digits in 28 patients who suffered high-pressure injection injuries of the hand during the last 10 years. They were all men, with a mean age of 36 years. All were work injury and the injuries were classified into mild, moderate and severe and were either treated conservatively or surgically. There were seven patients with mild injuries and six of these were successfully treated by conservative methods. Sixteen patients had moderate injuries and all were successfully treated with repeated debridement and delayed direct closure. The index fingers of two severely injured patients were salvaged with digital artery flaps and the remainder of the involved fingers were amputated. The authors advocate proper identification of mild injuries to allow conservative treatment, the application of digital artery flaps for resurfacing large finger defects and have formulated a treatment protocol according to the severity of the injury.
