Shoulder, infiltration origo caput longum biceps brachii
 Long head of biceps brachii, origin
PATIENT'S POSTURE The patient lies supine, the arm 90° abducted, elbow bent 90° ; an assistant grasps the forearm and holds the arm in 45° short of full lateral rotation.
PRODUCT 2 ml triamcinolone acetonide (10 mg/ml)
SYRINGE 2 ml syringe
NEEDLE 0.7x40 mm (22 G 1 ½)
TECHNIQUE In the position, described above, the bicipital groove lies level with the anterior edge of the acromion and with the origin of the long head of biceps.. The thumb of the free hand is put on the groove just beyond the acromion. The needle is inserted some 1 cm distal to the thumb and glides backwards and medially in the groove. After about 3 cm the tendinous resistance is felt, followed by bony contact. Here some twenty droplets are infiltrated into the origin of the tendon by slightly moving the needle in various directions. In this infiltration a strong resistance is encountered. If no resistance is felt before the bony contact, the needle lies too far on the scapula.
