  1. The Elbow

  2. Important Anatomical Facts • Median nerve and brachial artery lie medial to the biceps tendon and superficial to brachialis muscle • The radial nerve and its branch posterior interosseus nerve lie lateral to the biceps tendon • Ulnar nerve at the elbow lies behind (posterior) to the medial epicondyle • The main extensor muscles of the hand originate from lateral epicondyle • The main flexor muscles of the hand originate from medial epicondyle

  3. Tennis Elbow Commonest cause for elbow pain 35-50 age group Pain on lateral side of elbow History of lifting heavy object, recent excessive over activity- dusting, sweeping, playing tennis Golfer’s Elbow: Similar history but the pain is at the site of flexor tendons origin Less common than tennis elbow

  4. Elbow Tests • The chair test: Ask the patient to attempt the chair (3.5kg) with the elbows extended. Difficulty or pain confirms tennis elbow. • Flex the elbow and fully pronate the hand. Pain over lateral epicondyle. • Pain can also be elicited by pronating the arm with elbow fully extended.

  5. Thomsen’s Test: Ask the patient to clench the fist, dorsiflex the wrist and extend the elbow. Then force to palmar flex the wrist against resistance. Severe pain over lateral epincondyle . Same can be done with extended middle finger trying to flex it against resistance. Golfer’s elbow: Flex the elbow,supinate the hand, and then extend the elbow. Pain occurs over medial epicondyle
