Question 1

Question
Which of these is not true about rotator cuff tears?
Answer
  • a massive tear a tear larger than 5 cm
  • highest incidence occurs in the geriatric population
  • most rotator cuff tears are caused by progressive, degenerative microtrauma
  • subscapularis tears occur with teres minor tears
  • most commonly torn rotator cuff muscle is supraspinatus

Question 2

Question
Impingement syndrome occurs when the [blank_start]suprasinpatus tendon[blank_end] is trapped between the [blank_start]humeral head[blank_end] and the [blank_start]acromion[blank_end].
Answer
  • suprasinpatus tendon
  • labrum
  • biceps long head tendon
  • humeral head
  • glenoid fossa
  • acromion
  • corocoid process

Question 3

Question
Which of these is true about the causes of impingement syndrome?
Answer
  • a misshapen acromion can narrow the subacromial space further increasing the likelihood of the supraspinatus tendon entrapment
  • repeated rubbing on top of humeral head can form a callus which narrows space where supraspinatus tendon sits
  • excessive lordosis can bring humeral head closer to acromion, decreasing space for supraspinatus tendon
  • rotator cuff insufficiency leads to inferior movement of the humeral head

Question 4

Question
Which of these is true about impingement syndrome?
Answer
  • Pain past 140 degrees of abduction is a sign of this syndrome
  • the subacromial space closes up during the top abduction resulting in less pain
  • the painful arc sign is between 80 and 135 degrees
  • the painful arch sign is between 135 and 170 degrees

Question 5

Question
Tendonitis of the biceps long head tendon may develop with impingement syndrome.
Answer
  • True
  • False

Question 6

Question
Detachment of the biceps tendon from the labrum most often occurs in the baseball players. It is usually very painful and is always repaired with surgery.
Answer
  • True
  • False

Question 7

Question
A SLAP tear occurs at the [blank_start]labrum[blank_end]; the tear happens from [blank_start]anterior[blank_end] to [blank_start]posterior[blank_end].
Answer
  • labrum
  • glenoid fossa
  • biceps tendon long head
  • anterior
  • superior
  • lateral
  • posterior
  • inferior
  • medial

Question 8

Question
During a SLAP tear the supraspinatus tendon may be torn.
Answer
  • True
  • False

Question 9

Question
Conservatively most SLAP tears are repaired with debridement.
Answer
  • True
  • False

Question 10

Question
Debridement and labral repair surgeries both require very conservative movement and have difficult course of rehab.
Answer
  • True
  • False

Question 11

Question
A dislocation is a partial subluxation of the shoulder joint as a result of a structural instability.
Answer
  • True
  • False

Question 12

Question
Frozen shoulder...
Answer
  • is self limiting and symptoms disappear in 6 months
  • comes on after a traumatic event, lasts 12-18 months and requires surgery
  • the first 3-4 months are minimal pain with limited PROM, followed by a great deal of pain with limited AROM
  • after initial period of limited movement due to pain, there is a lot of stiffness and then it goes away

Question 13

Question
Which of these is not true about surgical neck fractures?
Answer
  • occurs more in elderly population
  • can be set with closed reduction
  • may happen as a result of a fall
  • the hardware for ORIF stays in the bone

Question 14

Question
Which of these is true about epicondylitis?
Answer
  • lateral epicondylitis occurs due to excessive wrist flexion against resistance
  • epicondylitis usually occurs as result of a fall
  • medial epicondylitis occurs due to excessive wrist flexion with no resistance
  • A right handed golfer may develop medial epicondylitis on their right wrist.

Question 15

Question
Which of these is not true about olecranon fractures and dislocations?
Answer
  • olecranon dislocations may occur with olecranon fractures
  • olecranon dislocations happen due to a fall with an outstretched hand with a rotational component
  • olecranon fracture occurs as an avulsion with the biceps tendon
  • olecranon fractures can happen due to a direct blow to elbow

Question 16

Question
Which of these is not true about radial head dislocation?
Answer
  • cannot bend elbow
  • cannot supinate/pronate
  • happens to children due to large anular ligament and small radial head
  • occurs when someone distract radial head from ligament

Question 17

Question
True carpal tunnel syndrome is the median nerve compression at the carpal tunnel due to a traumatic injury.
Answer
  • True
  • False

Question 18

Question
Which of these is true about rheumatoid arthritis?
Answer
  • diagnosis made from x-rays
  • chronic inflammation of tendons
  • MCPs of hand look subluxed
  • fingers drift radially

Question 19

Question
Which of these is true about orthopedic conditions that affect the hand?
Answer
  • De Quervain's tenosynovitis occurs due to swollen tendon sheath of extensor pollicis longus and brevis
  • Person's suffering from trigger finger do not have passive range of motion in the affected fingers.
  • Person's with Dupuytren's deformity have a contracture of the joints, commonly in the 4th and 5th digits.
  • Boutennier's deformity is exhibited by flexion at the DIP, extension at PIP and some extension at MCP.
  • Persons with Boutennier's deformity, swan neck deformity and mallet finger do not have PROM in the affected joints.

Question 20

Question
Which of these is true about open and closed reduction of colles fracture?
Answer
  • possible median nerve damage with open reduction
  • open reductions are indicated for well reduced fractures
  • open reductions are indicated for fractures with cartilage damage
  • closed reduction is more difficult to perform

Question 21

Question
Which of these is not true of CTS after colles fracture?
Answer
  • the median nerve was severed
  • fractured ends of radius put pressure on median nerve
  • median nerve was injured during reduction
  • carpal tunnel shows stiffness and swelling after casting

Question 22

Question
Which of these is true about shoulder dislocations?
Answer
  • most common type of shoulder dislocation occurs due to an anterior structural weakness
  • the most common type is an anterior dislocation
  • an inferior dislocation occurs due to electric shock
  • an anterior dislocation occurs when arm is elevated and internal rotated

Question 23

Question
The most commonly injury nerve in a shoulder dislocation is the...
Answer
  • axillary nerve because it wraps around head of humerus
  • axillary nerve because it is behind the head of humerus
  • median nerve because it wraps around head of humerus
  • radial nerve because it is behind the head of the humerus
