End of Year 1 (EoY1) Mock Paper
15 SAQs (15 x 10 = 150 marks)
,A 25-year-old man presents to A&E with significant pain in his left hand, specifically in the
anatomical snuffbox area. After an X-ray scan of the hand, it is determined by the clinician
that a scaphoid fracture has occurred.
An image of the anatomical snuffbox is shown below:
1. What forms the medial and the lateral border of the anatomical snuffbox? (2 x mark)
(State clearly which is medial and lateral)
There are many neurovascular structures located in this region.
2. Name the nerve and its corresponding branch that is located within the anatomical
snuffbox? (2 x ½ mark)
,An X-ray of the fracture is shown below.
There has been a fracture of the waist of the scaphoid bone.
3. With reference to the vasculature of the scaphoid bone, explain why avascular
necrosis can occur? (2 x marks)
Alongside this injury, the patient is being tested for any further nerve injury. This is called the
Froment’s sign. This is a test where you are testing for adduction of the thumb.
4. Name the muscle that can carry out adduction of the thumb and the nerve responsible
for the innervation of this muscle? (2 x ½ marks)
, The histology of cortical bone is shown below:
A is a structure and B is a cell part of the bone.
5. Name structure A? (1 x mark)
6. What substance does cell B deposit? (1 x mark)
There are many cells involved in healing bone fractures.
7. Name the 4 stages involved in the healing of bone fractures in chronological order
(4 x ½ marks)
