Clinical Concerns Tennis Elbow (elbow tendinitis) Inflammation, soreness, or pain on the outside (lateral) side of the upper arm near the elbow. There may be a partial tear of the tendon fibers, which connect muscle to bone. The tear may be at or near where these fibers begin, on the outside of the elbow Cure Put ice on the outside of your elbow 2 - 3 times a day. Take nonsteroidal anti-inflammatory medications An occupational therapist can show you exercises to stretch and strengthen the muscles of your forearm Cause The part of the muscle that attaches to a bone is called a tendon. Muscles in your forearm attach to the bone on the outside of your elbow. When you use these muscles over and over again, small tears develop in the tendon. Over time, this leads to irritation and pain where the tendon is attached to the bone

Slide 12

Surface Anatomy Lateral Epicondyle A small, tuberculated eminence, curved a little forward, and giving attachment to the radial collateral ligament of the elbow-joint, Medial Epicondyle Larger and more prominent than the lateral epicondyle, It gives attachment to the ulnar collateral ligament of elbow joint. The ulnar nerve runs in a groove on the back of this epicondyle

Slide 13

Surface Anatomy Radial styloid process A projection of bone on the lateral surface of the distal radius bone. It extends obliquely downward into a strong, conical projection. The radial collateral ligament of the wrist attaches at its apex. Ulnar styloid process Projects from the medial and back part of the bone; it descends a little lower than the head, and its rounded end affords attachment to the ulnar collateral ligament of the wrist-joint.

Slide 14

Cubital fossa The shallow triangular depression on the anterior surface of the elbow. The cubital fossa contains four main vertical structures (from lateral to medial: Radial Nerve, Biceps brachii tendon, Brachial artery, Median nerve. Superficial dissection Deep dissection Surface Anatomy Olecranon A large, thick, curved bony eminence of the forearm that projects behind the elbow.

The way the forearm angles away from the body when something is carried, such as a pail of water. More pronounced in women than men. Carrying Angle Surface Anatomy

Slide 16

Medial bicipital groove On the surface anatomy of the upper arm. It is formed by the hollow between the biceps and triceps muscles Tendons are tough strips of tissue that connect muscles to bones and allow us to move our limbs. Triceps tendon Attaches the ulnar bone at the elbow Biceps tendon Attaches to the radius bone at the elbow Surface Anatomy

Nerves Median Nerve Radial Nerve Ulnar Nerve Musculocutaneous Nerve

Slide 18

Brachial artery Provides the main arterial supply to the arm and is the continuation of the axillary artery. Ulnar artery Decends through the anterior compartment of the forearm, deep to the pronator teres. Radial artery Leaves the forearm by winding around the lateral aspect of the wrist and crossing the floor of the anatomical snuff box to reach the hand. Arteries

Slide 19

Recurrent interosseous artery Anterior interosseous artery Posterior interosseous artery Superficial palmar arch Formed predominantly by the ulnar artery with a contribution from the superficial palmar branch of the radial artery. Deep brachial artery (Profunda) Largest branch of the brachial artery in the upper part of the arm. Arteries
