Question 5

Name the borders of the deltopectoral triangle.

Answer 5

Superior: Clavicle
Laterally: Deltoid
Medially: Pectoralis Major

Question 6

What passes through the deltopectoral triangle?

Answer 6

The Cephalic Vein and the deltoid branch of the thoracoacromial artery.

Question 7

What is located in the posterior axillary fold?

Answer 7

Latissimus Dorsi and Teres Major

Question 8

From where do you measure the arm?

Answer 8

From the acromial angle to the lateral condyle of the humerus

Question 9

What injuries are involved with the biceps brachii?

Answer 9

• Biceps tendonitis
• Dislocation of tendon
• Tendon rupture of the long head
  (From Lots of Throwing)
• Popeye Deformity (Forceful flexion like in Weight lifting or swimming)

Question 10

Which demographic has a higher percentage to receive a fracture/dislocation of the proximal humeral epiphysis?

Answer 10

• Teenagers (Boys less than 18 and Girls less than 16)

Question 11

What is significant about fracturing the nutrient humeral artery?

Answer 11

It would take relatively longer to heal that fracture than another in the humerus.

Question 12

How to control a hemorrhage or bleeding from a brachial artery?

Answer 12

Compress near the middle of the arm to control the bleeding.

Question 13

If the arm needed to be clamped due to the brachial artery, where should they be clamped?

Answer 13

Distal to the deep artery of the arm as it will prevent tissue damage.

Question 14

What should always be considered when there is a fracture of the humeral body?

Answer 14

The possibility of a radial nerve lesion

Question 15

What would be observed in a radial nerve lesion from a humeral body fracture?

Answer 15

• Triceps would weaken from loss of medial head only, so there would be just weak extension of the forearm/arm.

Question 16

What would occur with a supracondylar fracture?

Answer 16

Nerves or branches of the vessel may be affected near the triceps and brachialis

Question 17

What are the two main superficial veins?

Answer 17

The Cephalic and the Basilic veins

Question 18

If radial nerve is severed at the radial groove, what can occur?

Answer 18

Medial head of triceps and everything distal to it will not be innervated by the radial nerve.

Question 19

True or false? Can elbow flexion still occur if the musculocutaneous nerve is cut?

Bonus: What nerve innervates the brachioradialis?

Answer 19

True, it can still occur because there are muscles like the brachioradialis to perform elbow flexion. It will be a weak flexion.

Radial nerve

Question 20

What are the effects of an injury to the musculocutaneous nerve?

Answer 20

• Weakness in elbow flexion and in supination.

Question 21

What are the effects of an injury to the radial nerve?

Answer 21

Paralysis in triceps, brachioradialis, supinator, Extensors of the wrist and digits besides the ones innervated by the ulnar nerve.

Question 22

A main characteristic to radial nerve injuries?

Answer 22

• The wrist drop, however, they can still move their fingers at the PIPs and DIPs, NOT THE METACARPOPHALANGEAL

Question 23

What lies in the cubital fossa?

Answer 23

TAN
TENDON of the biceps brachii
Brachial ARTERY
Median NERVE

Question 24

What are the only flexors in the FOREARM that are not innervated by the Median Nerve?

Answer 24

Medial part of the Flexor digitorum profundus and the Flexor Carpi Ulnaris.

Question 25

The retinaculate ligament connects what two structures together in the hand?

Question 26

What is the name for tennis elbow?

Answer 26

Elbow Tendonitis or Lateral Epicondylitis

Question 27

What is lateral epicondylitis?

Answer 27

Inflammation of the extensor muscles and pain is felt across the lateral epicondyle. The pain radiates down the posterior surface of the forearm.

Question 28

What is the name of golfer’s elbow?

Answer 28

Medial epicondylitis

Question 29

What is Mallet or Baseball finger?

Answer 29

When the DIPs are put into forced flexion, tearing the tendon from the joint.

Question 30

What is always considered when there is a fracture of the olecranon?

Answer 30

Surgery should always be considered before consulting PT treatment.
