image Injection to and into the Brachial Artery













Indications:


Circulatory disturbances, causalgia, post-traumatic osteoporosis of the upper extremity.


Materials:


Size 2 needle, 1 ml procaine or lidocaine.


Technique:


Point of insertion:


a: Palpate the artery a little above the antecubital fossa and inject intra- and para-arterially.


b: The artery can also be readily palpated in the axilla, where it issues from beneath the greater pectoral muscle and runs along the medial biceps groove.

image Injection to the Subclavian Artery
















Indications:


Circulatory disorders, cellulitis, abscesses, frostbite, burns to the upper extremity.


Materials:


40-mm-long needle, 2 ml procaine or lidocaine.


Technique:


Point of insertion: The pulsating artery can be palpated 10 mm above the mid-point of the clavicle.


As an alternative: stellate ganglion, brachial artery.



CAUTION: To avoid the risk of perforating the pleural apex, do not insert the needle further than 15 mm.

image Injection into the Elbow Joint






















Indications:


All disorders in the region of the joint.


Materials:


Size 12 needle, 2 ml procaine or lidocaine.


Technique:


The patient lays the forearm on a table to form approximately a right angle between the forearm and upper arm.



Point of insertion: Midway between olecranon and lateral epicondyle.



Direction of needle: Toward the antecubital fossa.



Injection depth: Approximately 10–20 mm.

image Injection into the Wrist Joint



















Indications:


Arthrosis, arthritis, post-traumatic joint disorders.


Materials:


Size 12 needle, 1 ml procaine or lidocaine.


Technique:


Point of insertion: Midway between the end of the ulna and the styloid process or between the distal end of the radius and the scaphoid bone.



Direction of needle: Perpendicular to the skin.



Injection depth: 5–10 mm.

image Injection into the Shoulder Joint






















Indications:


Arthrosis deformans, humeroscapular periarthritis, subacromial bursitis; conditions following contusion of the shoulder.


Materials:


40-mm-long needle, 2–5 ml procaine or lidocaine.


Technique:


Injection from the front:



Point of insertion: The patient lets the arm hang down, palm to the front; medially from the head of the humerus, the joint line can be palpated. The needle should enter just below the clavicle.



Direction of needle: Just below the acromion in an outward direction.



Injection depth: After overcoming the resistance from the ligaments, the needle slides easily into the joint.

image Injection to the Median Nerve






















Indications:


For disorders of the hand in the area supplied by this nerve; carpal tunnel syndrome.


Materials:


Size 12 needle, 1–2 ml procaine or lidocaine.


Technique:


a: In the antecubital fossa, the median nerve lies on the ulnar side of the palpable brachial artery.



b: Above the wrist.



Point of insertion: About three fingerbreadths above the line of the wrist joint, the nerve lies in a radial direction from the tendon of the palmaris longus muscle and is clearly visible in volar flexion of the hand.



Direction of needle, injection depth: Perpendicular to the skin until the patient reports paresthesia in the region supplied by this nerve.

image Injection to the Radial Nerve






















Indications:


Disorders of the hand in the area supplied by the radial nerve.


Materials:


Size 12 needle, 1–2 ml procaine or lidocaine.


Technique:


a: The radial nerve is accessible above the elbow.



Point of insertion: About four fingerbreadths above the lateral epicondyle.



Direction of needle: Perpendicular to the skin.



Injection depth: If the needle’s position is correct, the patient reports electrifying pain in the thumb and the back of the hand.

b: In the region of the wrist, feel for the pulse of the radial artery about three fingerbreadths above the joint line.


Point of insertion: Radially from the radial artery.


Injection depth: Until the patient reports paresthesia.


c: Distribution of a local anesthetic in the dorsoradial region of the wrist at snuffbox level blocks the branches of the superficial radial nerve.


Direction of needle, injection depth: Perpendicular to the skin, subcutaneous.

image Injection to the Ulnar Nerve



















Indications:


Disorders affecting the area supplied by this nerve, e. g., pain, vasospasm.


Materials:


Size 12 needle, 2 ml procaine or lidocaine.


Technique:


a: Point of insertion: The ulnar sulcus is palpable between the medial humeral epicondyle and the olecranon.



Direction of needle: Perpendicular to the skin.



Injection depth:
