Articulations of the humerus, radius, and ulna. [ olecranon process ]Medial collateral ligament: 3 portions, anterior, posterior, oblique
The anterior fibers are tight in extension, while the posterior fibers are tight in flexion [ beyond 90 degrees ] The posterior fibers are fan shaped and thin when compared to the anterior fibers.
Symptoms: Point tenderness @ lateral epicondyle; radiating pain to mid forearm and into the middle and ring finger; stiffness in elbow.
Elbow: flexion - extension
Wrist: supination - pronation - ulnar and radial deviation flexion and extension
Flexion and extension originate at the humeroradial and humeroulnar joints while pronation and supination occur from the radio scaphoid (Navicular)
articulations at the wrist and the radioulnar joint at the elbow.
6. Dislocations (fractures of the coronoid process occur in approx. 35-40% of elbow dislocations)
Dislocations of the elbow are infrequent occurrences in intercollegiate athletics.
However, when they do occur, the are often serious injuries due to the potential for fractures and impaired distal circulation.
