Which condition is an MSD example that involves nerve entrapment of the ulnar nerve?

• A. Ulnar Nerve Entrapment
• B. Median Nerve Entrapment
• C. De Quevain's Tenosynovitis
• D. Tendonitis

Answer: (A)

Nerve entrapment is a common mechanism in musculoskeletal disorders, where a nerve is compressed along its course and causes sensory and motor symptoms. Ulnar Nerve Entrapment is the example that fits this pattern because the ulnar nerve becomes compressed, typically near the elbow (cubital tunnel) or the wrist (Guyon’s canal). This compression leads to numbness or tingling in the little finger and the ulnar half of the ring finger, and weakness of the intrinsic hand muscles that control finger movements. The other conditions do not involve entrapment of the ulnar nerve: one refers to entrapment of a different nerve (the median nerve), and the remaining entries are inflammatory tendon conditions rather than nerve compression. Thus, the condition that matches ulnar nerve entrapment is the correct choice.
