Question 1

Which nerve passes through the cubital tunnel at the elbow and is most vulnerable to compression there?

Accepted Answer

Ulnar nerve

Answer

The ulnar nerve passes posterior to the medial epicondyle through the cubital tunnel, making it highly susceptible to entrapment and compression.

Question 2

The anatomical snuffbox is bordered radially by which tendon?

Accepted Answer

Extensor pollicis longus

Answer

The ulnar (medial) border of the anatomical snuffbox is formed by the extensor pollicis longus tendon, while the radial border is formed by abductor pollicis longus and extensor pollicis brevis.

Question 3

Which of the following is the primary stabilizer of the distal radioulnar joint (DRUJ)?

Accepted Answer

Triangular fibrocartilage complex (TFCC)

Answer

The triangular fibrocartilage complex (TFCC) is the primary stabilizer of the distal radioulnar joint and also distributes load across the ulnar side of the wrist.

Question 4

The lateral compartment of the leg contains which muscles?

Accepted Answer

Peroneus longus and peroneus brevis

Answer

The lateral compartment of the leg contains the peroneus (fibularis) longus and peroneus brevis, both innervated by the superficial peroneal nerve.

Question 5

Which bone of the foot articulates with both the talus proximally and the navicular distally?
