Question 5

How to measure Acromiohumeral space

Answer 5

Distance from inferior surface of acromion process to superior articular surface space of humeral head.

Question 6

Measurements for Acromiohumeral space

Answer 6

• 7-11 mm
• <7mm: rotator cuff tear
• > 11mm: subluxation, joint effusion, neuropathy

Question 7

How to measure Glenohumeral joint space

Answer 7

measure and average joint space at superior, middle and inferior aspects.
Use anterior glenoid margin

Question 8

Measurements for glenohumeral joint space

Answer 8

• Normal 4-5mm
• <4mm: arthritis
• > 5mm: dislocation

Question 9

acromioclavicular joint space

Answer 9

Best in A-C view

Question 10

Measurement for Acromioclavicular joint space

Answer 10

– Average 3mm; should be <2-3mm difference R to L
– < with arthritis
– > with dislocation, subluxation, resorption

Question 11

• A line through the shaft of the radius should extend through the radial head and mid-capitellum
• Can be used on essentially any elbow view to identify radial head dislocation

Answer 11

Radiocapitellar line

Question 12

• Line tangential to anterior humeral cortex should intersect at middle 1/3 of capitellum
• Capitellum posterior to this line indicates supracondylar fracture (especially useful in children)

Answer 12

Anterior humeral line

Question 13

• Line through and parallel to shaft of radius; second line tangential to distal articular surface of radius; measure proximal palm side angle

Answer 13

Lateral radius angle

Question 14

Lateral radius angle measurement

Answer 14

• Normal: 79-94° (Distal articular surface of the radius is tilted palmar)

Question 15

Ulnar variance measurement

Answer 15

• Distal radius projects 0-3 mm beyond the ulna
• > 3mm = negative ulnar variance
• Ulna more distal = positive ulnar variance

Question 16

Carpal row alignment

Answer 16

On the PA wrist (or hand), the alignment of the carpals should be evaluated.
The proximal articular surface of the proximal row.
The distal articular surface of the proximal row, and
The proximal articular surface of the distal row should be roughly parallel.

Question 17

Measurement for Coracoclavicular distance

Answer 17

Normal 11-13 mm and there should be no greater than 5 mm difference between the left and right side

Question 18

How to measure Coracoclavicular distance

Answer 18

From superior aspect of coracoid process to closest point on clavicle.

Question 19

How to measure carrying angle

Answer 19

Two lines are drawn, one through he midshaft of humerus and the other through the midshaft of the ulna.

Question 20

Measurement of Carrying angle

Answer 20

Normal angle is 154-178 degrees, with the average at 169 degrees.

Question 21

How to measure humeral angle

Answer 21

Humeral shaft line and humeral articular line.

Measure medial side

Question 22

How to measure ulnar angle

Answer 22

Ulnar shaft line and humeral articular line.

Measure medial angle (distal)
