CCEP Peripheral Nerve Entrapments & Neurological Conditions 3

Question 1

Which clinical finding best differentiates pronator teres syndrome from carpal tunnel syndrome?

Accepted Answer

Symptom reproduction with resisted forearm pronation

Answer

In pronator teres syndrome, median nerve compression occurs at the pronator teres, so resisted pronation reproduces symptoms; positive Phalen's test and nocturnal worsening are more characteristic of carpal tunnel syndrome.

Question 2

The sural nerve is typically formed by contributions from which two nerves?

Accepted Answer

Tibial and common peroneal nerves

Answer

The sural nerve is typically formed by the medial sural cutaneous nerve (from the tibial nerve) and the lateral sural cutaneous nerve (from the common peroneal nerve).

Question 3

Wartenberg's syndrome (cheiralgia paresthetica) involves entrapment of which nerve at the distal forearm?

Accepted Answer

Superficial radial nerve

Answer

Wartenberg's syndrome involves entrapment of the superficial branch of the radial nerve where it emerges between the brachioradialis and extensor carpi radialis longus tendons at the distal forearm.

Question 4

Posterior interosseous nerve (PIN) syndrome produces which characteristic clinical finding?

Accepted Answer

Inability to extend the fingers and thumb with preserved wrist extension

Answer

The PIN supplies the finger and thumb extensors but not the extensor carpi radialis longus (innervated proximal to PIN branching), so wrist extension is preserved while finger and thumb extension are lost.

Question 5

Obturator nerve entrapment in athletes most commonly presents as:

Accepted Answer

Medial thigh pain worsening with exercise and adductor weakness

Answer

Obturator nerve entrapment typically presents with medial thigh pain and paresthesia that worsens with exercise, along with adductor weakness, as the obturator nerve supplies the adductor compartment.
