Morning stiffness as an independent clinical symptom is mostly seen in rheumatic and rheumatoid diseases. It generally refers to tightness, stiffness, immobility or restriction of movement of the joints after prolonged immobility or morning awakening. The duration is considered as one of the criteria to measure the degree of activity of the lesion. The mechanism may be that when the body sleeps or exercises less, edema fluid accumulates in the loose synovial tissues around the joints, making the periarticular tissues swollen; after activity, as the muscles contract, the edema fluid is slowly absorbed by the lymphatic vessels and small veins, and the morning stiffness is relieved. The duration is directly proportional to the severity of the swelling of synovitis; synovial hyperplasia and exudation is also one of the main factors causing increased pressure within the carpal tunnel, which makes it easy to understand the occurrence of carpal tunnel syndrome in patients with morning stiffness of the hand. Carpal tunnel syndrome is a common condition caused by compression of the median nerve within the carpal tunnel, resulting in pain or paralysis of the piriformis muscle, often bilaterally. The pain often extends to the elbow and shoulder and is easily misdiagnosed as cervical spondylosis. When the carpal tunnel is degenerated, the canal is narrowed or the contents of the carpal tunnel are enlarged, the numbness and pain of the radial side of the 3.5 fingers are easily seen, and the pain is more pronounced at night or early in the morning, sometimes spreading to the elbow, and can be reduced or disappeared after shaking the hand. In the examination, it can be seen that the sensory and motor conduction speed of the ulnar nerve terminal that does not pass through the carpal tunnel is normal, and the sensory and motor fiber conduction speed of the median nerve in the segment below the wrist is slowed down, and the sensation of the median nerve distribution area is dull. The treatment of carpal tunnel syndrome is divided into two treatment methods: conservative treatment and surgical treatment. Conservative treatment is suitable for those with early onset and mild symptoms. For those with severe symptoms, long duration of the disease and ineffective conservative treatment, surgical treatment is required. At present, the treatment of carpal tunnel syndrome has been gradually improved from the traditional large incision surgery to small incision surgery and carpal arthroscopy. It has the advantages of small trauma, good effect and fast recovery.
