E N D
Lateral Epicondylitis(Tennis Elbow) • Lateral epicondylitis is a repetitive strain injury of the common extensor tendon at thelateral epicondyle of the humerus. • Symptoms persist because of constant traction movement of the wrist and hand.
Lateral Epicondylitis(Tennis Elbow) • Clinical Signs and Symptoms • Local lateral elbow pain • Weakness of the forearm
Cozen’s Test • Procedure: Patient seated. Stabilize forearm. Patient should make a fist and extend it against resistance. • Rationale: The tendons that extend the wrist attach to the lateral epicondyle. Forcing the extended wrist into flexion will exacerbate the pain if the tendons are inflamed.
Mill’s Test • Procedure: Patient seated. Instruct the patient to pronate the arm and flex the wrist. Then, instruct them to supinate against resistance. • Rationale: The supinator tendon is attached to the lateral epicondyle. If pain is elicited, suspect inflammation of the lateral epicondyle.
Medial Epicondylitis(Golfer’s Elbow) • Medial epicondylitis is a repetitive injury of the common flexor tendon at the medial epiconsyle of the humerus. • Symptoms persist due to constant traction and movement of the wrist and hand.
Medial Epicondylitis(Golfer’s Elbow) • Clinical Signs and Symptoms • Local medial elbow pain • Weakness of the forearm
Golfer’s Elbow test • Procedure: Patient seated. Instruct the patient to extend the elbow and supinate the hand. Then, instruct the patient to flex the wrist against resistance. • Rationale: The tendons that flex the wrist are attached to the medial epicondyle. If pain is elicited, suspect inflammation of the medial epicondyle.
Ligamentous Instability • Ligamentous instability of the elbow is relatively uncommon. • The injury may be caused by forced elbow hyperextension, forced abduction of the extended arm, or forced adduction of the extended arm.
Ligamentous Instability • Forced adduction will damage the radial collateral ligament. • Forced abduction will damage the ulnar collateral ligament.
Ligamentous Instability • Clinical Signs and Symptoms • Medial or Lateral elbow pain • Local swelling
Adduction Stress Test • Procedure: Patient seated. Stabilize the medial arm and place adduction pressure on the patient’s lateral forearm. • Rationale: Adduction pressure will stress the radial collateral ligament. Gapping and pain indicate radial collateral ligament instability.
Abduction Stress Test • Procedure: Patient seated. Stabilize the lateral arm and place abduction pressure on the medial forearm. • Rationale: Abduction pressure on the medial forearm applies stress to the ulnar collateral ligament. Gapping and pain indicate ulnar collateral ligament instability.
Neuropathy / Compression Syndromes • Neuropathy and compression syndromes of the elbow are peripheral neurological disorders. • They are caused by trauma, overuse, arthritis, and postural considerations.
Neuropathy / Compression Syndromes • Paresthesia and weakness of the forearm and/or hand. • The ulnar nerve is most often affected. • Compression occurs in the groove between the olecranon process and the medial epicondyle or the cubital tunnel.
Neuropathy / Compression Syndromes • Clinical Signs and Symptoms • Forearm and/or hand paresthesia • Forearm and/or hand weakness
Tinel’s Sign • Procedure: Patient seated. Tap the ulnar nerve in the groove between the olecranon process and the medial epicondyle with a neurological reflex hammer. • Rationale: If pain is elicited, it suggests a neuritis or neuroma of the ulnar nerve.
Causes of Ulnar Nerve Damage • Excessive use or repetitive motion injuries. • Arthritis of the elbow joint. • Cubital tunnel compression, between the heads of the flexor carpi ulnaris muscle. • Postural habits that compress the nerve, such as sleeping with elbows flexed and hands under head. • Recurrent nerve subluxations or dislocations.
