Abstract
The elbow joint is one of important joints of the upper extremity, because, it places the hand in space away from or toward the body. It provides the linkage, allowing the hand to be brought to the trunk, head, or mouth.
Normally, the arc of flexion extension ranges from 0 to 150 degrees and the arc of supination-pronation ranges from 85 degrees in supinalion to 75
•degrees in pronation. This range far exceeds what, is normally required lbr activities of daily living, which usually ranges from 30 degrees in extension to 130 degrees in flexion. Supination-pronation is from 50 degrees in pronation to 50 degrees in supination.
The post-traumatic elbow stiffness is considered as one of the most well recognized complication following elbow joint trauma and this due to specific anatomical features of the elbow joint and the way that periarticular tissues are responded to varying types of traumas. The causes of posttraumatic elbow stiffness can be classified into: extra-articular causes, iniraarticular causes and mixed causes.
For many years the post-traumatic elbow stiffness was belie\ ed to be unavoidable and almost untreatable but the more aggressive approach to the causes of the problem and recent advance in elbow arthroplasty have changed this opinion in recent years.
