With the development of sports in China and the development of the national fitness campaign, as well as the enhancement of public health awareness, the number of people playing various sports has increased year by year, but improper exercise often causes various sports injuries. Elbow canal syndrome is a nerve injury caused by compression of the ulnar nerve at the ulnar nerve groove of the elbow, and is one of the common peripheral nerve entrapment diseases in clinical practice. Prolonged and repeated elbow flexion can lead to increased pressure in the elbow canal, or hypertrophy and hyperplasia of the arcuate ligament, and cause entrapment and abrasion of the ulnar nerve, which is the common cause of elbow canal syndrome. About 20% of the patients with elbow canal syndrome seen in the Department of Rehabilitation Medicine develop the syndrome due to improper exercise, including martial arts, gym workouts, and golfing. Patients complain of ulnar hemi-numbness of the affected little finger and ring finger, and some have weakness in the affected hand, with severe atrophy of the little finger extensor and first interosseous muscle. The duration of the disease can be as short as a few weeks or as long as several years. Therefore, reasonable exercise and scientific fitness will be the key to prevent elbow-tube syndrome and other sports injuries. When a patient is diagnosed with elbow canal syndrome, he or she should stop the sports that cause injury in time to avoid further aggravation of the injury; in addition, it is recommended to seek medical advice and let the doctor give appropriate treatment according to the severity of the disease, including medication combined with physical therapy in the early stage to promote the timely recovery of nerve injury; in the later stage when the effect of conservative treatment is not very satisfactory, surgery can be considered. Electromyography plays an important role in the diagnosis and treatment of elbow canal syndrome. It can not only improve the positive rate of early diagnosis, but also provide accurate positioning for surgical treatment and provide surgical basis for small incision surgery in the clinic. Therefore, it is an important auxiliary tool for clinicians to diagnose and treat elbow-tube syndrome.
