Symptoms of Cubital Tunnel Syndrome

Many people are not particularly familiar with cubital tunnel syndrome. It refers to traumatic arthritis in the elbow, which often leads to nerve compression. The tissue between the two ends of the wrist flexor muscle on this side will compress the nerve. This symptom is called cubital tunnel syndrome. It has many symptoms, and patients often feel numbness in their little hand fingers, and become inflexible when writing or using chopsticks.

Symptoms of Cubital Tunnel Syndrome

In the early stages of the disease, patients often feel numbness and discomfort in the pulp of their little fingers. Sometimes I am not flexible when writing or using chopsticks. When the symptoms worsen, the ulnar wrist flexor and the deep flexor muscles of the ring and little fingers become weak, the intrinsic muscles of the hand atrophy, and a mild claw finger deformity appears. Froment syndrome ten.

Conservative treatment is suitable for patients in the early stages of the disease with mild symptoms. It can adjust the arm posture, prevent the elbow joint from excessive flexion for a long time, avoid sleeping with the elbow as a pillow, and wear elbow pads. Nonsteroidal anti-inflammatory analgesics may occasionally relieve pain and numbness, but steroid blockade of the cubital tunnel is not recommended.

Surgical treatment is suitable for patients with intrinsic hand muscle atrophy who have poor response to conservative treatment. The following surgical procedure is commonly used: the ulnar nerve is freed from the ulnar nerve groove and moved subcutaneously in front of the elbow. When the ulnar nerve is moved forward, it must be fully freed distally and proximally, and the articular branch and 1 to 2 muscular branches of the nerve must be cut off to facilitate its displacement toward the front of the elbow to prevent intramuscular compression after displacement. A piece of deep fascia is lifted at the origin of the flexor muscle to control the displaced ulnar nerve in the front of the elbow to prevent the displaced nerve from sliding back to its original position when the elbow is extended. The flipped deep fascia must have a certain width and length to prevent new compression of the ulnar nerve. Interfascicular release is generally not recommended as it may aggravate the symptoms. The elbow was immobilized in a plaster cast in flexed position after the operation, and exercise was started after 3 weeks. Although other surgical methods are also used clinically, they are not very popular.
