11. Clinical Concerns Clinical Concerns Tennis Elbow
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 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

12. Surface Anatomy Lateral Epicondyle Medial 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

13. Surface Anatomy Radial styloid process Ulnar 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.

14. Superficial dissection
Surface Anatomy
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
Olecranon
A large, thick, curved bony eminence of the forearm that projects behind the elbow.

15. Surface Anatomy Carrying Angle
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.

16. Surface Anatomy Medial bicipital groove Triceps tendon Biceps tendon
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

18. Arteries Brachial artery Ulnar artery Radial 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.

19. Arteries 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 .
