Epicondylitis


FIGURE 6.27 Medial view of muscular structures at right elbow. (From Tank PW, Gest TR. Lippincott Williams & Wilkins Atlas of Anatomy. Philadelphia, PA: Lippincott Williams & Wilkins, 2009.)



PATIENT POSITION



  • Supine on the examination table with the head of the bed elevated 30 degrees.
  • Shoulder at 30 degrees of abduction and full external rotation.
  • The affected elbow is flexed at 90 degrees.
  • The wrist is in a neutral position.
  • The elbow is supported with the placement of chucks pads or towels.
  • Rotate the patient’s head away from the side that is being injected. This minimizes anxiety and pain perception.

LANDMARKS


1.  With the patient supine on the examination table, the clinician stands lateral to the affected elbow.


2.  Identify and mark the point of maximal tenderness adjacent to the medial epicondyle.


3.  At that site, press firmly on the skin with the retracted tip of a ballpoint pen. This indention represents the entry point for the needle.


4.  After the landmarks are identified, the patient should not move the elbow.


ANESTHESIA



  • Local anesthesia of the skin using topical vapocoolant spray.

EQUIPMENT



  • 3-mL syringe
  • 25-gauge, 1-in. needle
  • 1 mL of 1% lidocaine without epinephrine
  • 0.5 mL of the steroid solution (20 mg of triamcinolone acetonide)
  • One alcohol prep pad
  • Two povidone–iodine prep pads
  • Sterile gauze pads
  • Sterile adhesive bandage
  • Nonsterile, clean chucks pad

TECHNIQUE


1.  Prep the insertion site with alcohol followed by the povidone–iodine pads.


2.  Achieve good local anesthesia by using topical vapocoolant spray.


3.  Position the needle and syringe perpendicular to the skin with the needle tip directed laterally toward the medial epicondyle.


4.  Using the no-touch technique, introduce the needle at the insertion site (Fig. 6.28).


5.  Advance the needle to the bone of the medial epicondyle.


6.  Withdraw the needle 1 to 2 mm.


7.  Inject the steroid solution steadily into this area. If increased resistance is encountered, advance or withdraw the needle slightly before attempting further injection.


8.  Following injection of the corticosteroid solution, withdraw the needle.


9.  Apply a sterile adhesive bandage.


10.  Instruct the patient to move his or her wrist and elbow through their full range of motion.


11.  Reexamine the elbow in 5 min to confirm pain relief.
