What is Bassett's lesion associated with?

• A. Entrapment of the ulnar nerve
• B. Entrapment of the lateral antebrachial cutaneous nerve
• C. Pain in the shoulder with overhead activities
• D. Radial nerve compression

Answer: (B)

Bassett's lesion is associated with the entrapment of the lateral antebrachial cutaneous nerve. This condition occurs when the nerve, which provides sensory innervation to the skin of the lateral forearm, becomes compressed, typically due to anatomical anomalies or its relationship with surrounding structures.

Understanding this lesion is important because it can lead to symptoms such as pain, numbness, or tingling along the forearm. It often arises in certain occupational settings or with repetitive overhead activities, where sustained positions or movements may lead to nerve entrapment. Identifying lateral antebrachial cutaneous nerve involvement is essential for clinicians to develop an effective management and treatment plan for patients experiencing these symptoms.

The other options relate to different types of nerve entrapments or conditions that do not specifically align with Bassett's lesion, highlighting the need for specificity in diagnosing nerve-related issues in the forearm region.
