Clinical Anatomy Of Elbow Joint By R M T
Bursitis of elbow • Subcutaneous olecranon bursitis causes: • Fall on elbow • Rub or scrap of skin over olecranon • Pressure and friction at olecranon. Also known as student’s elbow or miner’s elbow.
Subtendinous olecranon bursitis • Causes • friction between triceps tendon and olecranon. • Repeated flexion and extension. • Severe pain during flexion.
Avulsion of Medial Epicondyle • Fall that causes Abnormal abduction of extended elbow Causes: • Ulnar collateral ligament starting from medial epicondyle pulls the medial epicondyle distally (medial epicondyle do not fuse with humerus untill 20 years of age due to epiphysial plate)
Ulnar nerve damages in this condition as it passes posterior to medial epicondyle
Dislocation of Elbow Joint. • Posteror dislocation occurs when children fall on their hands with flexed elbow. • Radius and ulna dislocate posteriorly • Distally humerus is driven through anterior weak part of capsule.ulnar nerve coronoid process or olecranon process can be damaged.
Sublaxation and dislocation of Radial Head • Children suddenly lifted up,while forearm is pronated.child refuse to use the limb and protect by flexing and pronating elbow.radial head is sublaxated from annular ligament
