- 1.AMBRI stands for Atraumatic Multi-directional Bilateral Rehabilitation Inferior Capsular Shift and is most common in young women who are systemically hypermobile. To be considered multidirectional, the instability can be anterior or posterior, but must also be superior.
- A.
True
- B.
False
- 2.A patient who has instability will always have laxity.
- A.
True
- B.
False
- 3.Which of the following is not true regarding the articulating surfaces of the GHJ?
- A.
It has 160* coverage.
- B.
The glenoid inclination angle is 95*.
- C.
There is 5* retroversion.
- D.
Humeral retroversion is 30*.
- 4.What is the most common secondary complication after dislocation?
- A.
Recurrent dislocation.
- B.
HillSach's lesion.
- C.
Long Head of biceps Tear.
- D.
Neurovascular Injury.
- 5.The circle concept states that for instability to occur, changes must occur on both sides of the capsule. Therefore, when the humeral head goes anterior, the 1st restraint is the anterior capsule, but plastic deformation must occur on the posterior capsule for true instability to occur.
- A.
True
- B.
False
- 6.The SGHL acts to prevent inferior displacement of the humeral head when the arm is abducted to 45*. The coracohumeral ligament behaves much like the SGHL.
- A.
True
- B.
False
- 7.SLAP II is the most common type of SLAP lesion and is the only SLAP with the biceps detached.
- A.
True
- B.
False
- 8.If you want to best visualize shoulder instability, which 2 radiograph views are the best?
- A.
True AP, Y view
- B.
Scapular AP, Axillary
- C.
Axillary, True AP
- D.
Y, Scapular AP
- 9.A Grade III AC dislocation means that both the AC and CC ligaments are torn. The patient will have slighy ecchymosis and will have a large step-off deformity.
- A.
True
- B.
False
- 10.What is lucatio erecta?
- A.
A cord-like MGHL with a hole in the anterior superior labrum.
- B.
Capsulolabral tear of the superiro labrum.
- C.
When the humeral head becomes stuck under the glenoid.
- D.
A sublabral foramen found in 12% of shoulders
- 11.Open Bankart Repair is superior to Arthroscopic. Suture Tacks are superior to transglenoid sutures. If the labrum is cut it makes the shoulder 20% more unstable. The shoulder has a negative pressure inside. The cut for a Bankart if made in the deltopectoral region. There are subscap takedown precautions when the cut is vertical.
- A.
True
- B.
False
- 12.All of the following are mechanisms of a dislocation, EXCEPT:
- A.
AbD/Er
- B.
Forced flexion
- C.
FOOSh
- D.
Traction
- 13.The jerk test tests the intergrity of:
- A.
Anterior capsule
- B.
Posterior capsule
- C.
SGHL
- D.
IGHL
- 14.Which of the following statements is NOT TRUE?
- A.
A SLAP lesion has better healing potential than a Bankart lesion.
- B.
Posterior dislocations are uncommon.
- C.
The superior 1/2 of the labrum is loosely attached to the glenoid.
- D.
A Grade III Hillsachs means that there is a large defect of the subchondral bone.
- E.
The temperature for thermal capsulorraphy is typically between 65 and 75 * C.
- 15.Paralabral ganglion cysts can occur with a TYPE II SLAP lesion. They occur in the suprascapular notch and often affect the Axillary nerve.
- A.
True
- B.
False
- 16.When treating AC joint arthrosis, one should try an injection before they try iontophoresis.
- A.
True
- B.
False
- 17.O'Briens is a test for instability.
- A.
True
- B.
False
