Elbow Osteokinematic & Arthokinematic Relationships

Question 1

Radiohumeral Flexion Arthokinematics

Answer 1

0-150deg
0:45: anterior roll, anterior glide
45-135: cephalic roll, cephalic glide
135-150: posterior roll, posterior glide

Question 2

Radiohumeral Arthokinematics Extension

Answer 2

150-135: anterior roll/anterior glide
135-45: caudal roll/caudal glide
45-0: posterior roll/posterior glide

Question 3

Capsular pattern of elbow

Answer 3

greater loss of flexion than extension

Question 4

LPP of Humeroradial joint

Answer 4

full supination, full extension

Question 5

LPP of humeroulnar joint

Answer 5

70deg of elbow flexion, 10-30 deg of supination

Question 6

LPP of superior/proximal Radioulnar joint

Answer 6

70deg of elbow flexion

10-30deg of supination

Question 7

LPP of Distal/inferior radioulnar joint

Answer 7

10-30 supination (doesn’t matter what elbow is doing; because this joint is not involved in the elbow)

Question 8

Superior/proximal radioulnar joint arthokinematics pronation

Answer 8

Anterior roll

Posterior glide

Question 9

superior/proximal radioulnar joint arthokinematics supination

Answer 9

roll: posterior
glide: anterior

Question 10

inferior/distal radioulnar joint arthokinematics pronation

Answer 10

anterior roll/anterior glide

Question 11

inferior/distal radioulnar joint arthokinematics supination

Answer 11

posterior roll/posterior glide

Question 12

Pronation normal ROM

Answer 12

75-85 deg

Question 13

Supination normal ROM

Answer 13

85-90deg
