Mechanism of Injury

The classic stor y is of a climber cr imping when the f inger is loaded rapid ly due to either a foot-slip or pul ling dynamically to make a dif f icult move. There is often a gr uesome, audible “pop” at the time of injur y which is cal led an acute r upture. Another cause results from working a project or tr ying the same move multiple times. Then, sometime during the climbing, or shor tly thereafter, pain and tender ness is felt at the base of the f inger.
