Rationale for change

UWorld QID 1634 is about Guyon canal syndrome with injury to the hook of the hamate. It asks you to recognize the syndrome by decreased sensation over the fifth digit and a flattened hypothenar eminence.

Educational objective:
The ulnar nerve is commonly injured at the elbow (funny bone) or wrist (Guyon canal). Injury at Guyon canal results in sensory loss over the medial 1½ digits and intrinsic hand weakness. The hypothenar eminence may flatten due to muscle atrophy.
