This was a freak accident, at the climber's regular gym, on a wall that she had climbed many times. Several factors contributed to the injuries: trying to hold on whilst falling caused the right arm to be forcefully pulled above the head, the awkward angle of the fall onto new bouldering matting from height was unfortunate, and the hardness of the matting for an average height and weight female climber resulted in a harder impact. The route was a dynamic, comp style boulder, but was within the climber's ability. This accident was bad luck, but has raised awareness that overhead traction of arms can be a cause of traumatic nerve injuries, leading to long term injury. The climber's extreme joint hyper-mobility was potentially a contributing factor.
