Wrist

Question 1

True or False: The wrist should accept and transfer force, place our hand in space for function (ROM), and have protective reflexes.

Answer 1

True

Question 2

True or False: The distal radio-ulnar joint (DRUJ) is highly relevant to function of the elbow

Answer 2

False: The distal radio-ulnar joint (DRUJ) is highly relevant to function of the wrist

Question 3

The TFCC is responsible for:

Answer 3

Transferring and dispersing force in the wrist

Question 4

What is the most common fracture in the wrist?

Answer 4

Distal radius fracture

Question 5

What are the types of distal radius fractures?

Answer 5

Colles, Smith’s, Barton’s, Chauffer’s, Die punch

Question 6

Colles DRF:

Question 11

Clinical considerations- loss of radial inclination leads to:

Answer 11

Loss of UD and grip strength

Question 12

Clinical considerations- loss of palmar tilt leads to:

Answer 12

Decreased ROM

Question 13

Clinical considerations- radial shortening leads to

Answer 13

Ulnar variance and ulnar sided pain
