High-pressure injection injuries to the hand: A 14-year descriptive study.

Background: High-pressure injection (HPI) injury is an unusual type of injury in hand trauma, which could lead to a serious morbidity. We aimed to assess the clinical presentation, management, and outcome with HPI injury of the hand.

Methods: A retrospective study was conducted between 2001 and 2015 for patients with HPI injuries who were admitted to a Level 1 trauma center. We reviewed the medical records, imaging files, and demographic data including gender, age, mechanism of injury, and site of hand injury. The kind of injected materials, time to first treatment procedure, clinical management, and complications were also described.

Results: A total of 32 cases of HPI injuries were included in the study. The average age of the patients was 32.7 ± standard deviation 8.3 years, and all the patients were right handed. The most common material involved was grease (53%), followed by paints (25.0%), chemicals (9.4%), and air (6.3%). The most commonly affected part of the hand was the palm (31.3%), followed by index finger (25.0%). The average delay in the presentation was 12 h (range 3-96 h), and the mean hospital stay was 5.8 days. Management included debridement (90.6%) or conservative treatment (9.4%). Complications included chronic pain (9.4%), followed by amputation (3.1%).

Conclusions: HPI injury is not uncommon, usually underestimated, and needs more community awareness, particularly laborers. Delay of treatment could increase the risk of amputation. Therefore, it is important to inform the risk groups about the seriousness of such injuries and to take preventive measures.
