What is a common symptom of Guyon's canal syndrome affecting the 4th and 5th digits?

• A. Increased mobility in the hand
• B. Parasthesia on the palmar side
• C. Pain in the wrist during extension
• D. Numbness in the thumb

Answer: (B)

Guyon's canal syndrome typically results from compression of the ulnar nerve as it passes through Guyon's canal at the wrist. This condition particularly affects the area supplied by the ulnar nerve, which includes the 4th and 5th digits. One of the hallmark symptoms of this syndrome is paresthesia, which refers to abnormal sensations such as tingling or "pins and needles" in the palmar side of these digits. This occurs due to the dysfunction of the ulnar nerve, which can lead to sensory disturbances in the areas it innervates. Notably, symptoms associated with this syndrome can include decreased sensation or altered sensations, such as paresthesia, in the distribution of the ulnar nerve. While the other options provide some symptoms associated with different conditions or aspects of ulnar nerve involvement, paresthesia specifically addresses the sensory changes that are most characteristic of Guyon's canal syndrome in affecting the 4th and 5th fingers.
