What is a crush injury?
It all begins with an idea.
Crush injuries are the result of three forces upon the hand: compression (increase in pressure), avulsion (tearing away), and shearing (friction). Although the skin may be left intact there can be extensive damage to the structures underneath.
Sometimes in crush injuries, surgery may be required to reconstruct damaged structures and remove dirt, debris or dead tissue in the hand. Fractured bones may need to be pinned or plated, and tendons may need to be reattached. Early movement of specific joints may be prescribed if the bones are rigidly fixed and tendons are not damaged or they have been repaired with sufficient strength.
Treatment for crush injuries can include splinting, heat, retrograde massage with elevation, range of motion exercises and functional activities. Continuing activities of daily living, such as combing your hair, buttoning a jacket, etc. is good for maintaining function and should be done as advised by your therapist.
Scar tissue formation is important to provide stability to your healing structures. Sometimes a scar can form adhesions that attach to tendons, bones, skin, etc. and this may limit your ability to move your fingers and wrist. Your therapists will give you instructions on how to carry out the appropriate scar management techniques.
