biceps long head tenosynovitis
Introduction
Introduction to biceps tendonitis The long head of the biceps muscle passes through the intercondylar sulcus of the humerus and enters the anterior part of the subacromial space, ending at the scapula of the scapula. The tendon sliding in the intercondylar notch of the humerus is passive, that is, when the shoulder joint is adducted, the tendon slides upward when the internal rotation and the extension are extended, and the abduction and external rotation, the tendon slides downward when the flexion occurs. The biceps tendon tenosynovitis is a lesion in which this part of the tendon undergoes long-term wear and tear during the movement of the shoulder joint, which causes degeneration, adhesion, and impaired tendon sliding function. The disease occurs in patients over 40 years old. The main clinical features are pain in the sulcus and nodular joint, and shoulder movement is limited. If not treated in time, it can develop into a frozen shoulder. basic knowledge Sickness ratio: 0.01%-0.02% Susceptible people: more common in middle-aged people Mode of infection: non-infectious Complications: frozen shoulder
Cause
The cause of long head tenosynovitis of the biceps
(1) Causes of the disease
The disease may be acutely affected by trauma or strain, but most of it is the result of degenerative changes due to long-term wear and tear of the tendon.
(two) pathogenesis
1. The tendon is worn in the intercondylar sulcus of the humerus: the long head of the biceps muscle enters the shoulder joint through the intercondylar sulcus of the humerus, and the transverse ligament on the ridge ridge limits the tendon in the ditch, in daily life and work. The upper arm is often located on the front side of the body and is in the inner rotation position, so that the long-headed biceps tendon is squeezed toward the inner side wall of the internodal sulcus, which is prone to wear and degeneration, especially the congenital variation or cause of the inter-nodular groove. The fracture of the surgical neck of the humerus makes the bottom of the groove shallow, the surface is rough and uneven, and even the bone spurs are formed.
2. The tendon suffers from subacromial impact for a long time: the intra-articular part of the long-headed biceps tendon is located in the front part of the subacromial space. When the shoulder joint is abducting, the part and the shoulder blade can wear and collide. For a long time, the tendon undergoes degenerative changes.
3. secondary to shoulder inflammation: biceps tendon sheath and the shoulder joint cavity, any chronic inflammation of the shoulder joint can cause tendon sheath congestion, edema, cell infiltration, and even fibrosis, tendon sheath thickening, Adhesion is formed, which hinders the sliding function of the tendon.
Prevention
Biceps long head tenosynovitis prevention
It is related to trauma or strain, so prevention of trauma is the key to this disease. Therefore, paying attention to production and life safety is the key to prevent this disease. In social production activities, production is carried out through the harmonious operation of people, machines, materials, environment and methods. The potential accident risks and damage factors in the process are always in an effective state of control, and the lives and health of workers are effectively protected.
Complication
Biliary tract biceps tenosynovitis complications Complications
Longer patients can be combined with frozen shoulder.
Symptom

General symptoms
This disease is more common in middle-aged people and is one of the common causes of shoulder pain. It is mainly characterized by shoulder pain, more obvious at night, increased after shoulder activity, and relieved after rest. The pain is mainly limited to the biceps tendon. Involved in the anterior side of the upper arm, any action that can make the tendon tense, slip or pull can aggravate the pain.
2. Local symptoms and characteristics
During the examination, there is tenderness on the intercondylar sulcus or tendon. When the forearm is in the anti-resistance and flexion elbow, the pain occurs in the internodal groove. The Yergason sign is the main basis for diagnosis. In the acute phase, the shoulder can be caused. The active and passive activities of the joints are limited, and the deltoid muscles may present with protective tendons. In patients with longer course of disease, or those with periarthritis of shoulder or other diseases, shoulder stiffness and muscle atrophy may be seen.
Examine
Examination of biceps tenosynovitis
1. Most patients only need to check the first item in the "A".
2. If you need surgery, you should check all the items in the box "A";
3. For a definitive diagnosis or differential diagnosis, individual patients may make a B item in the examination frame.
Diagnosis
Diagnosis and differentiation of long head tenosynovitis of biceps
According to the medical history, the general symptoms of clinical manifestations, local symptoms and characteristics, such as the Yergason sign (+) can establish a diagnosis.
