Epicôndilo: Entendendo Projeções Ósseas e Formação de Articulações

An epicondyle is a rounded bony prominence on the distal femur or humerus, superior to the condyle, serving as attachment for muscles and ligaments.

• Medial Epicondyle (Humerus): Origin of forearm flexors/pronators (common flexor tendon); ulnar nerve runs posteriorly (cubital tunnel).
• Lateral Epicondyle (Humerus): Origin of forearm extensors/supinators (common extensor tendon); site of tennis elbow (lateral epicondylitis).
• Medial/Lateral Femoral Epicondyles: Attachments for collateral ligaments, gastrocnemius, popliteus.

Epicondylar fractures (especially humeral) are common in children; require anatomic reduction to prevent growth arrest or nerve injury.
