Cubital tunnel syndrome is a nerve compression disorder of the ulnar nerve at the level of the elbow. Ulnar nerve entrapment is a condition where the ulnar nerve becomes physically trapped or pinched, resulting in pain, numbness, or weakness, primarily affecting the little finger and ring finger of the hand.
Entrapment may occur at any point from the spine at cervical vertebra C7 to the wrist; the most common point of entrapment is in the elbow (Cubital tunnel syndrome). Prevention is mostly through correct posture and avoiding repetitive or constant strain (e.g. “cell phone elbow”).
Treatment is usually conservative, including medication, activity modification and exercise, but may sometimes include surgery. Prognosis is generally good, with mild to moderate symptoms often resolving spontaneously.
