UMU Polls Flashcards
Which of the following structures is the primary restraint against G-H joint ER with the arm at 45 deg abduction?
Middle Glenohumeral ligament
During protraction of the shoulder girdle, what glide occurs at the Sternoclavicular joint? (describing motion of clavicle on manubrium)
Anterior glide (concave on convex)
[elevation glides inferior and depression glides superior - would be convex on concave]
Your patient is lacking G-H internal rotation on the right compared to the left that you suspect is capsulo-ligamentous in nature, based on what you now know about the glenohumeral joint, what mobilizations might you try to improve this motion?
G-H joint inferior glide, posterior glide, and anterior glide
What is the distal attachment of the subscapularis muscle?
Lesser tubercle of the humerus
Which of the following resists/restricts superior migration of the clavicle? (multiple answers)
Costoclavicular lig.
Conoid lig.
Acromioclavicular lig.
Which ligaments are most powerful at resisting superior migration of clavicle?
Trapezoid and Conoid ligaments (Coracoclavicular lig.)
Which of the following is the primary stabilizer of the G-H joint at 90 deg of abduction?
Inferior glenohumeral ligament complex
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
- Stabilize the distal radioulnar joint
-Distribute/attenuate compressive forces on the ulnar side of the wrist
Which of the following ligaments resists valgus force at the elbow?
Ulnar Collateral ligament
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.)
Anterior (volar) glide of the radius on the ulna
[proximal radius is convex on concave ulna]
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
-Humeroulnar joint
-Proximal interphalangeal joint of digits 2-5
[MCP are condyloid joints
and CMC are ellipsoid]
Which of the nerves listed below provide innervation of the elbow joint via articular branches? (multiple answer)
Axillary?
Radial?
Ulnar?
Median?
Radial
Ulnar
Median
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?
Toward the radius (lateral glide in anatomical position)
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?
Extensor Digitorum can help to extend wrist if fingers kept straight/extended
Primary (Extensor carpi radialis longus, brevis; Extensor carpi ulnaris)
Which of the following would be a primary elbow flexor? (multiple answers)
Brachialis?
Brachioradialis?
Extensor carpi radialis?
Supinator?
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?
Anterior glide (figure 4)
Inferior glide
What is the primary function of the sacroiliac joint?
distribute forces from the trunk through the ring of the pelvis
Which of the following ligaments a the femoroacetabular joint restricts/limits hip extension
Iliofemoral
Ischiofemoral
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?
Anterior glide of tibia on femur
which of the following structures would be put under tension with a valgus force at the knee?
MCL
Which of the following would increase the risk of patellar instability/dislocation?
Trochlear dysplasia
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 ?
Anterior Glide of the talus on the tibia
Which of the following ligaments is most crucial in maintaining the medial longitudinal arch of the foot?
Plantar Calcaneonavicular ligament (spring ligament)
Which mobilization would help to improve eversion of the calcaneus on the talus? (multiple answer)
Distraction of calcaneus
Medial glide of calcaneus
Lateral glide of calcaneus
Pronation of the foot/ankle is commonly considered to be a combination of what three motions?
Dorsiflexion, eversion, abduction
[closed-chain: lock calcaneus and forefoot in place, so front of the talus will plantarflex and swing toward center]
What structures provide stability to the distal (inferior) tibiofibular joint? (multiple answers) (think high ankle sprain)
- Interosseus membrane/ligament
- Anterior inferior tibiofibular ligament
