Q

56 year old woman falls and sustains a fracture of the midshaft of her humerus. The doctor assessing her in the Emergency Department wishes to test the function of one of the nerves of the upper limb that is particularly vulnerable to injury due to its anatomical proximity to this location on the humerus.

Which of the following muscles could be tested to assess the function of the nerve that the doctor is concerned about?

A

Extensor carpi radialis longus

Q

23-year-old man sustains an injury to his upper limb. The doctor assessing him in the Emergency Department wishes to test the function of his ulnar nerve. Which movements could the doctor ask the patient to perform to test this nerve?

A

Abduction of the fingers is performed by the dorsal interossei muscles which are supplied by the ulnar nerve, so this would be a suitable test.

Q

An 83-year-old man is known to have osteoarthritis of his cervical spine. He begins to experience some altered sensation over the medial border of his left hand and his left little finger. He also complains of some weakness in his hand. He attends his GP practice, where the doctor assessing him suspects impingement of one of the nerve roots exiting his cervical spinal cord. Which nerve root is most likely implicated?

A

C8

17
Q

Which important bony landmark at the end of the iliac crest can be felt through the skin when a patient is supine, and is an attachment point for the inguinal ligament?

A

Anterior superior iliac spine

18
Q

An 89-year-old woman attends the emergency department having fallen on her left side. She cannot move her left hip and is in a lot of pain. An x-ray shows she has fractured part of her femur which has likely torn the retinacular arteries. Which is the most likely area to have fractured?

A

Neck

19
Q

A 28-year-old female rugby player attends an orthopaedic clinic with an acutely swollen painful knee after being tackled during a recent game. The orthopaedic surgeon examines the knee and notices that she is able to pull the patient’s tibia anteriorly whilst the femur is fixed.
Which structure has been damaged?

A

Anterior cruciate ligament

20
Q

A 45 year old patient books an appointment to see their GP as they have been struggling with weakness in their posterior hip muscles. They have noticed they are struggling to stand from sitting in a chair and on examination, they have bilateral weakness when extending and externally rotating their hips. Which muscle is responsible for these movements?

A

Gluteus maximus

21
Q

12-year-old boy is kicked in the anterior thigh during a football game and sustains a large bruise over this area. For the next few days he struggles to extend his knee and in the emergency department, the doctor suspects he has damage to the quadriceps femoris group of muscles. Which of the following muscles is part of the quadriceps?

A

Vastus intermedius

22
Q

72 year old woman strains her posterior thigh muscles whilst doing a workout class at the gym. Which nerve supplies the hamstring muscles?

A

Sciatic

23
Q

A 56 year old man is walking across a zebra crossing when a car fails to stop for him. The car’s front bumper strikes his leg on the lateral aspect, just below the knee. When he attends the emergency department, the doctor notices he is unable to dorsiflex his foot.

Which nerve that travels superficially over the lateral aspect of the leg, immediately inferior to the knee, supplies the muscles responsible for dorsiflexion?

A

Common fibular nerve

24
Q

A 23 year old athlete injured their calcaneal (Achilles) tendon during a race. They feel pain around their heel, and cannot plantarflex their foot.

Which of the following muscles inserts onto the calcaneus via the calcaneal tendon?

A

Soleus

Soleus combines with the tendons of gastrocnemius and plantaris to form the calcaneal tendon.

25
Q

A 45 year old woman suffers a prolapsed (‘slipped’) intervertebral disc in her spine and develops altered sensation in her leg. She reports partial numbness and tingling in her little toe and along the lateral border of her foot.

Which nerve root supplies sensation to this dermatome?

A

S1

26
Q

78 year old man has peripheral vascular disease and poor arterial circulation to his extremities. He is referred to the vascular surgery team and the surgeon attempts to palpate the pulses in the patient’s lower limb.

Which anatomical landmarks are used to locate the dorsalis pedis pulse?

A

between the tendons of extensor hallucis longus and extensor digitorum longus on the dorsum of the foot.

27
Q

Which anatomical landmarks are used to locate the great saphenous vein

A

Anterior to the medial malleolus, but medial to the tendon of tibialis anterior.

28
Q

Which anatomical landmarks are used to locate the femoral artery

A

Just below the midpoint of the inguinal ligament, between the anterior superior iliac spine and the pubic tubercle.

29
Q

Which anatomical landmarks are used to locate the posterior tibial artery

A

Posterior and inferior to the medial malleolus, but anterior and inferior to the calcaneus

30
Q

Which anatomical landmarks are used to locate the popliteal artery

A

Posterior to the knee joint, within the popliteal fossa.
