Abstract
The elbow is a hinge joint that is composed of the following articulations: humeroradial articulation, which is formed by the radial head and the capitulum of the humerus; humeroulnar articulation, which is formed by the ulnar notch and trochlea of the humerus, and the superior radioulnar articulation, which is formed by the proximal part of the ulna and radius. Muscles and ligaments connect the structures. A fibrous capsule surrounds the joint, and the radial and ulnar collateral ligaments reinforce it (De Smedt et al., 2007).
The elbow can be injured by direct trauma, or (frequently) from overuse due to repetitive arm, and hand movement, while both types of injuries can be quite individual and complex, several common elbow injury patterns are usually identified:
Elbow injuries are quite common in sports, especially those which use handheld equipment. Repetitive movements and cumulative microtrauma cause the tendon to damage. Many of these injuries are named after the sport in which they most often occur e.g.
Rehabilitation and prevention of elbow injuries are differing aspects of the same challenge. So, an appropriate and progressive rehabilitation program should be started early and the clinician must be aware of the priorities of rehabilitation which are:
1) Prevention of further damage.
2) Restoration of motion and strength.
3) Returning to ordinary activity.
If the patient is made aware of these principles, they will be more likely to progress at the best possible rate (Placzek et al., 2007).
The rehabilitation program for elbow injuries mainly depends on:
(1) Determination of the cause of the injury.
(2) Restriction or modification of the activities to prevent further damage.
(3) Massage should be applied after the acute stage-lightly at first, below pain level.
(4) Stretching exercises should begin as soon as possible, gently at first and continue throughout the rehabilitation process and after.
