ECRL Muscle: Crucial for Hand & Wrist Movements, Commonly Injured
The Extensor Carpi Radialis Longus (ECRL) muscle plays a crucial role in hand and wrist movements. It extends the wrist and flexes the elbow. Injuries to this muscle, such as lateral epicondylitis, are common and typically treated by orthopedic surgeons or sports medicine physicians.
The ECRL is part of a muscle group that includes the extensor carpi radialis brevis. It is controlled by the radial nerve and supported by the radial artery and vein for blood circulation. The ECRL originates along the lateral supracondylar ridge of the humerus and inserts at the posterior base of the second metacarpal, connecting to the index finger's phalanges.
Lateral epicondylitis, or 'tennis elbow,' is a common injury associated with the ECRL. It occurs due to overworking tendons in the elbow from repetitive forearm or hand movements. Specialist doctors, such as orthopedic surgeons or sports medicine physicians, treat this condition.
The ECRL is a vital muscle for hand and wrist movements, with its function controlled by the radial nerve. Injuries like lateral epicondylitis can occur, but specialist doctors can provide effective treatment.
