Ulnar groove Anterior Lateral

The ulnar groove is a deep channel on the surface of the front of the elbow joint. It separates two muscles that help in flexion and extension of the elbow: the flexor carpi longus and the pronator teres.

The anterior lateral groove is located on the outside of the elbow, on the side opposite the big toe. It is located between the pronator teres muscle and the flexor carpi longus muscle, and runs along the entire length of the ulnar groove.

The ulnar groove and the anterior lateral groove play an important role in the function of the elbow. They allow the muscles to flex and extend the arm and also provide stability to the joint. Additionally, these grooves help maintain proper arm posture and prevent elbow injuries during sports or physical activity.

For the proper functioning of the elbow joint, it is important to monitor the condition of these grooves and keep them healthy. If the grooves are damaged or excessively worn, it can lead to pain and limited movement. In such cases, it is recommended to consult a doctor for advice and treatment.

The anterior lateral ulnar groove (sulculus cubitalis anterolateralis) is a bony depression on the lateral surface of the elbow, which is located between the base of the medial and the base of the lateral epicondyle. This groove separates two sections of the bone: medial and lateral.

Anatomical location: The anterior lateral ulnar groove is located on the inner side of the radius from the outer root of the lateral condyle of the humerus to the radial edge of the lateral tendon. It begins as a flat lateral groove on the surface of the radius. The location of the anterior lateral ulnar groove can be felt on the radial surface of the shoulder at a distance of 4-5 cm from the elbow joint. Inner border: starts at the level of the middle of the upper border of the elbow
