medial epicondylitis
Introduction
Introduction to humeral epicondylitis The humeral epicondylitis, also known as the forearm flexor tendon injury or ulnar flexor carpal muscle injury. The total flexor of the forearm is attached to the upper iliac crest, which is similar to the pathology of the external iliac crest of the humerus. The difference is the injury and tension of the flexor, flexor and forearm pronation. The upper humeral epicondylitis is mainly caused by pain in the upper part of the elbow joint. Sometimes the pain will radiate from the inner side of the forearm. If the condition is severe, it can be repeated, the pain is persistent, causing the whole body to be weak, and even the object is dropped. basic knowledge Sickness ratio: 0.05% Susceptible people: no specific population Mode of infection: non-infectious Complications: bursitis
Cause
Causes of supracondylar humerus
The internal humeral epicondylitis is mainly caused by repeated traction and cumulative injury of the iliac crest in the forearm flexor. It is similar to the pathogenesis of tennis elbow. It is commonly seen in golfers, students, miners, and so on. , student elbow, miner elbow.
Due to the extension of the wrist and the forearm half-rotation, the elbow's valgus injury is caused by the sudden flexion of the wrist muscles, causing the forearm flexor tendon to be damaged in the upper iliac crest. Frequently exerting force on the wrist, flexion or forearm pronation, the wrist and the anterior circumflex muscle repeatedly contract, causing the iliac crest to be stretched for a long time, and fatigue injury occurs. Acute injury is common in the former. Chronic injuries are more common in the latter.
Prevention
Prevention of humeral epicondylitis
If the symptoms are mild, you should pay more attention to it. You can heal yourself after a few days or months. If you have repeated episodes, persistent pain, weakness, or even something in your hand will suddenly fall to the ground, you should seek medical attention as soon as possible. Pay attention to life:
1. When playing tennis or badminton, choose a racket with light texture, good elasticity and good quality to reduce the burden on the arm.
2. When buying food, try to use the cart, use less baskets; pay attention to the wrist posture when lifting the pot, pouring water, twisting clothes and carrying heavy objects, and do not falsify.
3. When mopping the floor with a mop, the legs are slightly bent, and the shoulders and arms are driven by the strength of the waist and legs, instead of using the power of the arm to drag.
4. If symptoms are present, the workload should be reduced as much as possible to avoid deterioration.
Pay attention to the acute phase:
1. Place the small ice cubes in a plastic bag, place them in a painful area, and then wrap them in an elastic bandage for 20 minutes each time; repeat several times and raise the affected part.
2. Suspend work, take local braking, and pay attention to rest in time.
Pay attention to the chronic phase:
In addition to local brake rest, protection, physical therapy, pressurized massage and oral non-steroidal anti-inflammatory drugs, mainly partial closure therapy. Even with prednisolone + 2% lidocaine, local infiltration of tender points. When receiving medication closure, pay attention to:
1. Avoid injecting the drug into the tendon or under the skin to avoid skin tendon or focal skin necrosis.
2. The number of closures should not be too much, 2-3 times is appropriate, each interval is 7-14 days, if it does not work, you should seek medical advice and replace other treatment methods.
Complication
Complications of humeral epicondylitis Complications bursitis
The disease is generally less complication, but if it is not treated in time, it can cause other diseases for a long time. The main possible complications are as follows:
1. Forearm secondary muscles are deep-skinned and swollen.
2. The degenerative deformation of the curved ligament of the bone.
3, excessive joint hyperplasia of synovial bursitis or synovial wrinkles.
Symptom
Symptoms of sacral sacral tendon common symptoms elbow pain elbow joint can not flex weakness
The clinical manifestations of this disease are mainly localized pain in the medial elbow joint, tenderness, flexion of the wrist, and normal elbow activity.
(1) Pain or soreness inside the elbow joint, especially when the forearm is pre-rotation and the wrist is actively flexed. The pain can be radiated down the ulnar flexor carpal muscle, the wrist is weak, and the bucket is difficult.
(2) There is obvious tenderness in the upper iliac crest, no swelling of the elbow joint, and normal activity.
(3) Forearm flexor tendon traction test positive: stretch the elbow wrist to stretch the fist, and then the forearm external or posterior rotation, causing pain inside the elbow.
Examine
Examination of humeral epicondylitis
According to the history and clinical manifestations, the disease can be diagnosed. If the diagnosis is further confirmed, the examiner can let the patient sit on the chair, put the forearm on the table, face up with the palm facing, and force the wrist to make a fist, and the examiner confronts it. It will stimulate the pain of the upper iliac crest and flexor tendon. Generally, no other auxiliary examination methods are needed. In special cases, X examination can also be performed, which should be based on the doctor's specific diagnosis.
Diagnosis
Diagnosis and diagnosis of humeral epicondylitis
The disease has repeated episodes of lateral elbow pain, local tenderness is obvious, the pain is exacerbated when the resistance stretches the wrist, and the X-ray has no obvious positive signs to confirm the diagnosis. If the pain and tenderness point in the medial humerus, the internal epicondylitis is called Golf elbow, ulna olecranon pain is also called miner elbow, student elbow, because the pathogenesis is similar to tennis elbow (external humeral epicondylitis), it is sometimes necessary to identify with the tennis elbow.
The external humeral epicondylitis is mainly due to the long-term, repeated, intense contraction and traction of the forearm extensor muscle group, causing different degrees of acute or chronic accumulation damage to the external iliac crest of the tibia, and the muscle fibers are torn and hemorrhage. Mechanization, adhesion, and clinical symptoms caused by a sterile inflammatory response.
1. The main clinical manifestation of external humeral epicondylitis is localized pain or persistent soreness of the elbow joint, especially for the rotation of the forearm. When the wrist is actively extended, the pain is more obvious, and it can be radiated to the forearm, wrist or upper arm. Pain, some night pain, weak grip, warming pot pouring water, sweeping the floor, twisting clothes and other movements.
2. Unlike the humeral epicondylitis, the localized tender point is located in the lateral epicondyle of the humerus, the annular ligament or the ankle joint.
