question 11 (mandatory) (1 point)
listen
a patient presents with tingling/paresthesis down the pinky. there is a clicking
sensation over the medial elbow that is provoked by elbow flexion. choose the most
probable diagnosis.
carpal tunnel syndrome
guyon canal syndrome
pronator syndrome
ulnar nerve dislocation

Explanation:

• Carpal tunnel syndrome: Usually affects the median nerve, causing symptoms in the thumb, index, middle, and half of the ring finger (not the pinky).
• Guyon canal syndrome: Involves the ulnar nerve at the wrist, not typically associated with a clicking sensation at the elbow.
• Pronator syndrome: Affects the median nerve in the forearm, not related to elbow - flexion - induced clicking and pinky symptoms.
• Ulnar nerve dislocation: The ulnar nerve supplies the pinky. When it dislocates (especially with elbow flexion), it can cause tingling (paresthesia) in the pinky and a clicking sensation at the medial elbow.

Answer:

ulnar nerve dislocation
