Question 2

What strengths the radio carpal jointe

Answer 2

Anterior and posterior ligament

Question 3

What movements does the radio carpal joint produce

Answer 3

Flexion, extension, abduction, addiction, circumduction

Question 4

Explain carpal tunnel ,including symptoms, aetiology, treatment and what structures are included

Answer 4

Symptoms: pain and pins and needles in distribution of median nerve (lateral 3 digits)
Aetiology: overuse, swelling of tendons and tendon sheaths, cysts arising from carpal joint
Structures: created from flexor retinaculum going between pisiform and hamate
Stuck between carpal bones, tendons hypertrophy and median nerve becomes trapped
4 tendons of flexor digitorium profundus
4 tendons of flexor digitorium long us
Tendon of flexor policy’s longus

Question 5

What is median nerve palsy

Answer 5

Inability to flex thumb, index and middle finger at MVP

Ring finger and little finger can still flex

Question 6

What is ulnar nerve palsy

Answer 6

Inability to flex the dip joint of ring and little finger

Can’t extend interphalangesl joints

Question 7

What is radial nerve palsy

Answer 7

Denier action of extensor muscle in forearm
Blood vessels compressed
Because forearm flexor muscles no longer opposed, wrist drops

Question 8

What kind of joint is the proximal radio ulnar joint and how is it held in place

Answer 8

Pivot joint, radius pivots about the ulna during pronation

Held in place by annular ligament

Question 9

What type of joint is the distal radio ulnar joint

Answer 9

Synovial pivot joint

Annular ligament holds radius head when turning

Question 10

What causes the radius to pop out in children

Answer 10

The distal radio ulnar joint makes the radius pop out of annular ligament as there is not much muscle reinforcement

Question 11

How is pronation of the forearm produced and what is it innervates by

Answer 11

Rotation of radius on capitulum of humerous
Enclosed by annular ligament
Produced by pronation quadrant us and pronation there’s

Innervated by median nerve

Question 12

How is supination of the forearm produced and what is it Innervated by

Answer 12

Produced by supinator and biceps brachial

Innervated by radial and musclulocutaneous nerve

Question 13

What type of joint is the elbow joint and how is it supported

Answer 13

Synovial hinge joint

Ulnar collateral ligament and radial collateral ligament

Question 14

What makes up the cubical fossa and what goes in it

Answer 14

Superior: elbow articulation between humerus, radius and ulna
Lateral and medial: brachial radialis pronation

Includes: tendon for biceps brachii, brachial artery, median nerves

Question 15

What are the anterior forearm muscles Innervated by

Answer 15

Median nerve

Question 16

What are the posterior forearm muscles Innervated by

Answer 16
