Absent sensation in regimental badge area and inability to forward flex the arm


C.

Inability to abduct the arm


D.

Inability to forward flex the arm

Loss of deltoid function



4. An obese patient undergoes a total shoulder replacement through a deltopectoral approach. The surgeon states that large soft tissue retractors had to be used.


Given the history, the most likely neurological deficit would be which of the following?

Altered sensation in lateral forearm and weak supination


C.

Altered sensation in regimental badge area


D.

Altered sensation in regimental badge area and deltoid palsy


E.

Middle and anterior deltoid palsy



5. A 24-year-old athlete sustains a traumatic dislocation of the left shoulder. Following reduction, he is noted to have absent sensation in the deltoid area.


Which of the following is most likely to be positive?



A.

Empty can test


B.

External rotation lag sign


C.

Gerber’s lift-off test


D.

Hornblower sign


E.

O’Brien’s test



6. A 36-year-old woman sustained a fall 3 months ago and was referred by her GP to Physiotherapy. She was noted to have her arm in fixed internal rotation with reduced flexion.


What would be the most useful investigation at this stage?

MRI


B.

MRI arthrogram


C.

X-ray


D.

Diagnostic arthroscopy


E.

US



7. A 32-year-old male undergoes a distal biceps tendon repair.


The most likely neurological deficit with this procedure is which of the following?

B.

Inability to extend the thumb but wrist extension with radial deviation present


C.

Altered sensation in the lateral forearm


D.

Altered sensation in the lateral forearm and weak supination


E.

Inability to flex the thumb IPJ and index/middle fingers DIPJ



8. A 7-year-old child sustains a lateral mass fracture of the right elbow.


What is the most likely late onset functional deficit?



A.

Inability to abduct the thumb


B.

Inability to adduct the thumb


C.

Loss of forearm supination


D.

Loss of thumb IPJ flexion


E.

Weakness of wrist extension



9. A 9-year-old girl falls off a trampoline and sustains an injury to her elbow (Figure 10.1).


The most likely structure to be injured will result in which of the following deficits?

A.

Altered sensations over the lateral aspect of forearm


B.

Inability to flex DIPJ of the index finger


C.

Inability to extend the wrist


D.

Inability to flex DIPJ of ring finger


E.

Inability to oppose the thumb to little finger



10. A 30-year-old male presents to clinic with pain and bruising in the anterior aspect of his right elbow. He says that 3 days ago he was in the gym and felt a pop in his distal arm.


If he wishes to proceed with non-operative management, he will likely lose approximately which of the following?



A.

50% of grip strength


B.

40% of supination strength


C.

80% of supination strength


D.

60% of flexion strength


E.

10% of flexion strength



11. A 36-year-old body builder sustains a distal biceps tendon rupture and is offered surgical repair.


The more common complication encountered with a two-incision technique as compared to a 1-incision is which of the following?



A.

Lateral antebrachial nerve injury


B.

Musculocutaneous nerve injury


C.

PIN injury


D.

Radial nerve injury


E.

Synostosis



12. A 25-year-old rugby player sustains recurrent anteroinferior traumatic dislocations of the shoulder. Plain MRI scan was normal and at arthroscopy, no soft tissue or bony Bankart lesion was found. The patient continued to experience recurrent instability.


Which of the following was the most likely lesion that was missed?

GLAD


B.

HAGL


C.

Kim lesion


D.

Long head of biceps tendon rupture
