ulnar neuritis
Pronunciation: UL-nar new-RYE-tis
Inflammation or irritation of the ulnar nerve, commonly occurring at the elbow in throwing athletes.
Full Definition
Ulnar neuritis refers to inflammation or irritation of the ulnar nerve, most commonly occurring at the cubital tunnel (behind the medial epicondyle of the elbow) in athletes. This condition is frequently seen in overhead throwing athletes and is often associated with valgus stress injuries of the elbow. The inflammation may result from direct compression, traction during throwing motions, or secondary to elbow instability. Athletes typically experience numbness and tingling in the ulnar nerve distribution (little finger and half of the ring finger), which may be accompanied by weakness in grip strength and intrinsic hand muscle function. Symptoms often worsen with prolonged elbow flexion or throwing activities. The condition may be acute or develop chronically over time.
Usage
Usage note: Distinguish from ulnar collateral ligament injuries; may coexist with other elbow pathology in throwers.
