MCQs of Joints of the Upper & Lower Limbs


  1. After ramming the point of his shoulder into a practice dummy, a football player suffered a severe shoulder separation. Although this is a dislocation of the acromioclavicular joint, several structures could be torn, including the one that gives the joint its greatest strength and stability, namely the:
    Acromioclavicular ligament
    Coracoacromial ligament
    Coracoclavicular ligament
    Supraspinatus tendon
    Tendon of the long head of biceps
    Ans: C
  2. While doing arthrography of the shoulder joint it was noted that the contrast material flowed into the subacromial (subdeltoid) bursa, along the tendon of the subscapularis and along the proximal part of the tendon of the long head of the biceps. The finding of contrast in which area was abnormal?
    into the subacromial (subdeltoid) bursa
    along the tendon of the subscapularis
    along the proximal part of the tendon of the long head of the biceps
    Ans: A
  3. While performing an arthrogram to study an apparent rotator cuff injury, it was noted that the contrast material had spread from the shoulder joint onto the anterior lateral surface of the scapula near the joint. When asked, the first year resident responded that this was due to an anterior tear in the cuff. Having just studied the shoulder joint you respond that the contrast is in a normal extension of the joint cavity called the:
    bicipital bursa.
    olecranon bursa.
    subacromial bursa.
    subscapular bursa.
    ulnar bursa.
    Ans: D

  4. Which muscle contributes to the “rotator cuff”?
    Latissimus dorsi
    Pectoralis Minor
    Teres major
    Ans: D
  5. A patient presented to his physician with chronic shoulder pain. It was noted that when asked to abduct his arm, he initially leaned laterally, and then straightened up. When iodinated contrast was injected into his shoulder joint it was found to be in the subdeltoid bursa as well as in the joint cavity. Which structure was damaged to produce the shoulder pain?
    Acromioclavicular ligament
    Long head of the biceps brachii muscle
    Subscapularis muscle
    Superior glenohumeral ligament

  7. A two year old child will not go to take her nap. Her mother tightly holds her left hand as she leads her to the bedroom. Refusing to go further, the child suddenly attempts to jerk away and then sits down screaming and holding her left elbow. In a attempt to calm her down her mother offers her a cookie, but she cannot supinate her left hand to receive it. Which joint was dislocated?
    the glenohumeral joint
    the humero-ulnar joint
    the humero-radial joint
    the proximal radio-ulnar joint

  8. You are in the emergency room when a student is brought in with a shoulder injury sustained while playing touch football. In comparing the symmetry of his two shoulders, you notice a marked elevation of the distal end of his clavicle with respect to the acromion on the injured side. X-ray exam reveals a grade III shoulder separation. In order for this to have occurred, which ligament must be torn?
    superior glenohumeral
    transverse humeral
    Ans: B
  9. A 3-year-old child walking hand-in-hand with her father screams in pain as he jerks her quickly up onto the curb to dodge a speeding car. The examining physician calls it a case of “pulled elbow”, a dislocation sometimes seen in young children and caused by:
    The head of the radius slipping part way out of the annular ligament
    Tear of the common extensor tendon
    Stretching of the radioulnar interosseous membrane
    Tear of the ulnar collateral ligament
    Ans: A
  10. A “pulled elbow” in a young child results when the radial head is dislodged from the:
    Annular ligament
    Insertion of biceps brachii
    Olecranon process
    Radial collateral ligament
    Ulnar collateral ligament
    Ans: A
  11. The shoulder is most often dislocated in which direction?
    Ans: A
  12. It was determined that a football player tore his coracoclavicular ligament. This is an example of a:
    Pulled elbow
    Rotator cuff tear
    Separated shoulder
    Dislocated shoulder
    Colles’ fracture
    Ans: C
  13. A father and child are about to step off a curb to cross a street when a car suddenly turns around the corner. In panic the father yanks on the child’s arm to pull him out of the way of the car. Safe on the curb, the child screams in pain and holds his elbow. The diagnosis is “pulled elbow;” the head of the radius has been pulled out of the socket holding it against the radial notch of the ulna. In order for the head of the radius to be dislocated in this way, what ligament must be stretched or torn?
    Glenoid labrum
    Radial collateral
    Ulnar collateral
    Ans: A

  14. While walking to class on an icy winter morning, a student slips and falls on her outstretched hand. The intense pain forces her to go to the emergency room. After X-rays of her wrist are taken, the attending says,” You were lucky, there is no Colles’ nor scaphoid fractures, but you have dislocated the middle carpal bone of the proximal row.” Which bone was dislocated?
    Ans: B
  15. The fibrocartilaginous structure which deepens the shoulder socket is the:
    Articular capsule
    Articular cartilage
    Glenoid labrum
