Spraining your wrist entails injuring the ligamentous structures surrounding the joint. The TFCC is one of the supporters of the wrist, supporting the hand and connection of the two forearm bones, radius and ulna. The TFCC stands for triangular fibrocartilage complex. In literature the TFCC is termed the “meniscus of the wrist,” because it functions similarly to the meniscus in the knee, distributing the load and partially absorbing the load in the wrist.
The humerus is the long bone of your upper arm. There are many muscles, ligaments, and nerves found along the humerus. Humerus fractures are named based upon the location of their fracture. Fractures which occur close to shoulder joint, injuring the ball and socket are proximal humerus fractures. Fractures which occur to the middle portion are called mid-shaft fractures and those along the lower portion are distal humerus fractures. With proximal humerus fractures, the majority are treated with a sling for 2-3 weeks and then exercises to regain function of the arm. More severe injuries of the proximal humerus may require surgical measures.
