What Is A “FOOSH” Injury?

It may happen while snowboarding or skateboarding. It can also just randomly occur while walking through a parking lot or in your own home. All of a sudden, you find yourself on the ground. It happens so unexpectedly. This is a FOOSH, an acronym which stands for “fall on outstretched hand”. This type of upper limb injury occurs when you try and break a fall with your outstretched hand.


An RSI (Repetitive Stress Injury) occurs when stress is placed on a joint, pulling on the tendons and muscles around the joint. When the stress occurs repeatedly, the body does not have time to recover and becomes irritated. The body reacts to the irritation by increasing the amount of fluid in that area to reduce the stress placed on the tendon or muscle. If not treated, it can lead to injuries to the soft tissues, tendons/muscles, and nerves.
As a certified hand therapist, I hear this story often. It may be a little ache, pain in their elbow, forearm, maybe their wrist, or even just one finger. They ignore it, thinking it subside on its own. Over time, it becomes more nagging, and may affect how long they can type on a keyboard or use a mouse. It is insidious and reaches a point where they realize it is not going away. This may lead to an injury called RSI.
