Question

In which of the following nerve injuries is the instrument shown below used?

• A. Radial nerve
• B. Median nerve
• C. Ulnar nerve
• D. Volkmann's ischemic contracture

Answer 1

The Correct Option is A

The instrument shown in the image is primarily used for conditions related to the Radial nerve injury. Radial nerve injuries are common in fractures of the humerus, especially the midshaft. The clinical presentation may include wrist drop due to the involvement of the extensor muscles of the forearm.

Radial Nerve Injury Symptoms
Wrist drop
Weakness of finger extension
Sensory loss on the dorsum of the hand

Management may involve the use of specific instruments for nerve repair or compression relief, such as nerve stimulators or decompression tools, as depicted in the image. This tool aids in assessing the nerve's functionality and planning surgical intervention if necessary. Therefore, it is used diagnostically and therapeutically in managing radial nerve injuries.
