ABSTRACT
Forearm injuries Forearm injuries are not common in sports but can occur from overuse in racquet sports or from high-energy falls in other sports.
The forearm serves as an anchoring point for the muscles and tendons that pass to the wrist and hand and to the fingers. The two bones of the forearm (radius and ulna) can rotate over each other. This provides power and allows for precise hand positioning for specialized functions. The forearm can therefore internally rotate (pronate) in the wrist and externally rotate (supinate) in the wrist (Fig. 13.1).
