Understanding the elbow nerve it is known as cubital tunnel syndrome. It is the erosion of a nerve (ulnar), which travels from the neck to the hand and who is responsible for the function of different hand muscles and sensation in the ring and little fingers. When the ulnar nerve is compressed produces what we call ulnar nerve compression or entrapment of the ulnar nerve. The patient has pain, tingling, numbness or burning, and sometimes, reduction or exaggeration of feeling in some fingers and medial edge of the forearm. Symptoms worsen to keep bending the elbow. To address this ailment can opt for conservative treatment (changes in activity, use of splints, rest, stretching and vitamin supplements) or surgery.
