Hand injury
Intense photo of patient that got his hand stuck in a wood grinder!! The injury happened when the operator lost control of the grinder as a result of his taking one hand off it whilst it was still turning at high speed. He had taken one hand off the grinder because he was attempting to prevent the piece of wood on which he was working from falling when it came out of a support stand. The grinding wheel was still turning at high speed and the gyroscopic precessing force acting on the tool was too great for the operator to handle with one hand. This led to the grinder being deflected into his other arm causing an injury. Fortunately maximum restoration of the injured hand can be accomplished by careful extrication, followed by preservation and reconstruction of all viable tissues. Perioperative antibiotics and wound irrigation with antibiotic solution are recommended.
