Middle Glenohumeral ligament

Question 2

Answer 3

G-H joint inferior glide, posterior glide, and anterior glide

Question 4

What is the distal attachment of the subscapularis muscle?

Answer 4

Lesser tubercle of the humerus

Question 5

Which of the following resists/restricts superior migration of the clavicle? (multiple answers)

Answer 5

Costoclavicular lig.
Conoid lig.
Acromioclavicular lig.

Question 6

Which ligaments are most powerful at resisting superior migration of clavicle?

Answer 6

Trapezoid and Conoid ligaments (Coracoclavicular lig.)

Question 7

Which of the following is the primary stabilizer of the G-H joint at 90 deg of abduction?

Answer 7

Inferior glenohumeral ligament complex

Question 8

Which of the following are a function of the TFCC (Triangular Fibrocatrilage Complex) at the wrist? (multiple answer)

• Stabilize the distal radioulnar joint
• Distribute/attenuate compressive forces on the ulnar side of the wrist
• Restrict flexion ROM at the wrist
  -Distribute/attenuate compressive forces on the radial side of the wrist

Answer 8

• Stabilize the distal radioulnar joint
  -Distribute/attenuate compressive forces on the ulnar side of the wrist

Question 9

Which of the following ligaments resists valgus force at the elbow?

Answer 9

Ulnar Collateral ligament

Question 10

Your patient is lacking 20 degrees of forearm supination and you suspect it is a result of joint accessory motion deficits, assuming the convex-concave rule holds true, which joint mobilization would you try to improve supination? (consider mobilization of the radius at the proximal radioulnar joint.)

Answer 10

Anterior (volar) glide of the radius on the ulna

[proximal radius is convex on concave ulna]

Question 11

Which of the following would be considered a hinge joint? (multiple answer)
-Humeroulnar joint
-Metacarpophalangeal joint of digits 2-5
-Carpometacarpal joint of digits 2-5
-Proximal interphalangeal joint of digits 2-5

Answer 11

-Humeroulnar joint
-Proximal interphalangeal joint of digits 2-5

[MCP are condyloid joints
and CMC are ellipsoid]

Question 12

Which of the nerves listed below provide innervation of the elbow joint via articular branches? (multiple answer)

Axillary?
Radial?
Ulnar?
Median?

Answer 12

Radial
Ulnar
Median

Question 13

Your patient is lacking ulnar deviation motion of the hand/wrist, assuming the convex-concave rule holds true at the wrist, what direction would you glide the proximal carpal row (carpals moving on distal radius) to help improve this motion?

Answer 13

Toward the radius (lateral glide in anatomical position)

Question 14

Which of the following muscle would be a secondary extensor of the wrist? (choose one)
Extensor carpi radialis brevis?
Extensor carpi radialis longus?
Brachioradialis?
Extensor digitorum?

Answer 14

Extensor Digitorum can help to extend wrist if fingers kept straight/extended

Primary (Extensor carpi radialis longus, brevis; Extensor carpi ulnaris)

Question 15

Which of the following would be a primary elbow flexor? (multiple answers)
Brachialis?
Brachioradialis?
Extensor carpi radialis?
Supinator?

Question 16

You note a deficit in passive hip ER motion for your patient that you are treating for lateral hi pain, which direction of joint mobilization would be most beneficial in improving this motion?

Answer 16

Anterior glide (figure 4)
Inferior glide

Question 17

What is the primary function of the sacroiliac joint?

Answer 17

distribute forces from the trunk through the ring of the pelvis

Question 18

Which of the following ligaments a the femoroacetabular joint restricts/limits hip extension

Answer 18

Iliofemoral
Ischiofemoral

Question 19

your 60 yr old patient that you are treating for knee pain is lacking 15 deg passive knee extension, assuming the convex-concave rule holds true, which of the following mobilizations would improve extension ROM?

Answer 19

Anterior glide of tibia on femur

Question 20

which of the following structures would be put under tension with a valgus force at the knee?

Answer 20

MCL

Question 21

Which of the following would increase the risk of patellar instability/dislocation?

Answer 21

Trochlear dysplasia

Question 22

Your patient arrives lacking 15 degrees of passive ankle plantar flexion following immobilization for a now well healed fibular fracture. Assuming the convex-concave rule holds true, what joint mobilization would be most beneficial to regain this ROM ?

Answer 22

Anterior Glide of the talus on the tibia

Question 23

Which of the following ligaments is most crucial in maintaining the medial longitudinal arch of the foot?

Answer 23

Plantar Calcaneonavicular ligament (spring ligament)

Question 24

Which mobilization would help to improve eversion of the calcaneus on the talus? (multiple answer)

Answer 24

Distraction of calcaneus
Medial glide of calcaneus
Lateral glide of calcaneus

Question 25

Pronation of the foot/ankle is commonly considered to be a combination of what three motions?

Answer 25

Dorsiflexion, eversion, abduction

[closed-chain: lock calcaneus and forefoot in place, so front of the talus will plantarflex and swing toward center]

Question 26

What structures provide stability to the distal (inferior) tibiofibular joint? (multiple answers) (think high ankle sprain)

Answer 26

• Interosseus membrane/ligament
• Anterior inferior tibiofibular ligament
