The Triangular Fibrocartilage Complex (TFCC) affects a group of cartilage and ligaments found near the smallest finger by the side of the wrist. The TFCC enables your wrist to manipulate your hands and carry out movements like gripping and hand rotation. It also bears the weight when you’re holding something, or putting force on your hand.
The TFCC is what keeps the bones in the forearms, called the radius and ulna, from pulling apart. It works like a shock absorber for the joints on your hands, therefore, a tear, lesion or injury in the TFCC may cause extreme and chronic wrist pain.
