The elbow is a joint extremely susceptible to stiffness, even after a trivial trauma. As for other joints, several factors can generate stiffness such as immobilization, joint incongruity, heterotopic ossification, adhesions, or pain. Prolonged joint immobilization, pursued to assure bony and ligamentous healing, represents the most acknowledged risk factor for joint stiffness. Consequently, increasing efforts have been channeling to achieve as much as possible elbow stability, thereby avoiding unfavorable prolonged immobilization. Nonetheless, immobilization time as well as energy of incipit trauma cannot predict the degree of joint stiffness suggesting as other elements may play significant role in contracture development. The elbow is a common site of nerve entrapment syndromes. The reasons are multifactorial but peculiar elbow anatomy and biomechanics play a role. Passing from the arm into the forearm, the ulnar, median, and radial nerves run at the elbow in close rapport with the joint, fibrous arches, and through narrow fibro-osseous tunnel. The elbow joint, in fact, has a large range of flexion which expose nerves lying posterior to the axis of rotation to traction and those anterior to compression.
