The main clinical symptoms are numbness of the 4th and 5th fingers, atrophy of the muscles in the interphalangeal area, limited range of motion, and reduced strength, which need to be differentiated from cervical spondylosis and other related diseases. Mild cases of elbow canal syndrome can be relieved by rest, physical therapy or oral neurotrophic drugs such as methylcobalamin or B vitamins. In particularly severe cases of elbow canal syndrome, clinical symptoms can only be relieved by surgical relief of the nerve compression problem. For example, surgery with anterior displacement of the nerve and the discovery of this disease should strive for early treatment, otherwise the nerve is compressed for a long time, the situation of muscle atrophy then after surgery is less effective, and the recovery process is longer.
