Preoperative photo illustrating the area where the infiltration anesthesia was applied to a patient planned for lacertus tunnel release. Thirty milliliters of 1 % lidocaine with epinephrine was administered subcutaneously 30 min preoperatively. The dotted lines mark the area of subcutaneous infiltration, covering the area of the lacertus fibrosus and the medial/central aspect of the elbow and forearm. Skin pallor can be seen as a result of the vasoconstrictive effect from the epinephrine. BT = biceps tendon; ME = medial epicondyle
