What caused the sudden fracture of mandibular joint?

Joint knowledge bell 1. What is the disease that all joints of the body always rattle?

I'm afraid it happens occasionally when every adult moves his joints.

So, where does the joint noise come from? Joint noise, one is physiological and the other is pathological. Generally speaking, those who only blink and have no painful dyskinesia belong to physiological blink.

During joint movement, there is no relative movement between articular surfaces, between cartilage pads and articular surfaces, between tendons and joint capsules, between tendons and bones, and between tendons and tendons. When they collide or rub against each other, they make a sound. This kind of snap caused by physiological activities of joints is physiological snap.

In most people, this sound is not obvious and inaudible, but in some people, it is more obvious and sounds clearer. This is caused by individual differences.

Your condition should be physiological, and you don't need special treatment, let alone panic. If necessary, you can go to the hospital for examination and do some physical therapy. Pathological joint snapping is generally accompanied by pain around the shoulder joint and limited activity. Young people are generally related to trauma. The elderly should consider local ligament strain, joint capsule relaxation, bone spur, osteoporosis and other reasons. Generally, you should go to a regular hospital as soon as possible to find out the reason, and carry out physical therapy or local closed treatment.

2. Why do joints bounce?

Sometimes there are noises in the joints, one is physiological and the other is pathological.

Physiological noise

Occasionally, when the human body suddenly makes a faster or unnatural movement, it often makes a single sound, such as a middle school student suddenly pulling his upper arm behind his back and making him bow down. The reason is that the shoulder joint is stressed, the speed is high, the range of motion is large, and the joint surfaces can not be completely attached. One joint surface rubs against the thick bone on the other joint surface and makes a noise. Because it is a slight collision between bones, it is similar to gently drumming, and the sound is small and dull. When going downhill or downstairs, the hip joint (thigh root) changes from flexion to extension, and the tendons or fascia around the joint slide over the protruding part of the femur next to the joint, making a noise. Because tendons and fascia are fibrous connective tissues, which are similar in nature to strings, sliding over femoral tuberosity is equivalent to plucking strings, so the sound is loud. The other is the sound made by pulling your fingers. It is that some people have painstakingly developed the habit of snapping their fingers. Because of the special structure of fingers, the flexion and extension of finger joints are pulled by the sliding of flexor tendons in the tendon sheath. Tendons vibrate when fingers are excessively bent or quickly straightened from flexion. However, it needs to be pointed out in particular that often pointing is a bad habit and should not be imitated.

Pathological noise

Different from physiological snapping, pathological snapping is mainly caused by joint capsule loosening. For example, when the hip joint bends, the femoral head often slides over the upper edge of the acetabulum, producing a click sound. Therefore, congenital malformation, acquired trauma, inflammation and other reasons lead to relaxation of hip joint capsule, which can cause hip joint snapping. There are many reasons for knee joint snapping, such as bone fragments, meniscus injury, congenital osteoarthropathy and so on. Another feature of knee snapping is that it may be "soft" or "stuck" when walking, sometimes accompanied by pain.

Snapping refers to manual workers, typists, urban white-collar workers and housewives who are interacting with computers. Fingers can't be straightened after bending, and snapping will occur when you straighten your fingers with your other hand. It is also called trigger finger, or flexor tendinitis. One of the reasons for the snap of shoulder joint is the relaxation of shoulder joint capsule, which leads to dislocation or subluxation of shoulder joint; The other is soft tissue degeneration at joints, which is caused by sliding over the bony process during activities. It can be seen that shoulder patting is mainly pathological shoulder patting, unless there are occasional slaps and frolics.

The last three points should be pointed out.

1. The distinction between physiological snapping and pathological snapping is actually very simple: the occasional snapping of a single joint, especially in special cases such as stumbling and fighting, is mostly physiological and does not need to be worried. Frequent and repeated snapping, especially those with pain, joint locking (card) and other complications, are mostly pathological and should go to the hospital for treatment.

2. Exercise should be scientific and avoid blindness. In addition to the discomfort caused by excessive movement of the shoulder joint, the excessive bending movement of the knee joint in circles will also lead to the relaxation of the knee joint capsule. Patients with "trigger finger" repeatedly bend and stretch their fingers, which will lead to the aggravation of their condition and make it difficult to recover.

3. There is an individual who is very nervous after the occasional physiological paroxysm, and tries to repeat the noise again and again, trying to find the reason, which is unnecessary.

3. What is the reason for the fracture of bones and joints?

What the hell is the bone always ringing?

Many people have had the experience of bone joint ringing. Some people make a "beep" sound when they make a fist. There is only going up and down the stairs, and the knee joints ring rhythmically. Others even stretch and yawn, and the back of the neck or temporomandibular joint will make a sound. What the hell is going on here? Is it growth, sprain, or does it mean that there is something wrong with the joint?

Usually, joint snapping can be divided into physiological and pathological, and most joint snapping is physiological, which will not cause discomfort to other parts of the body while making noise and will not harm the body, so it does not need special treatment or anxiety. However, some people will feel pain and swelling when their joints bounce, which may indicate that there is something wrong with the joints. The common diseases in clinic are meniscus injury and patellofemoral osteoarthropathy, and this pathological fracture is common in knee, ankle, hip and shoulder joint.

I suggest that some elderly people have chronic knee pain and sometimes have difficulty walking, which may be the extrapulmonary manifestation of lung cancer. Because the patient has no chest pain, cough, hemoptysis and other lung manifestations, it is easy to cause misdiagnosis and missed diagnosis.

Judging whether joint ringing is a hidden health problem has a lot to do with age. Generally speaking, young people's joint ringing is mainly due to physiological reasons, unless there is trauma; Once the elderly appear, we should consider whether there are local lesions, such as ligament strain and bone spur. In this case, we should go to a regular hospital as soon as possible, find out the real reason, and actively take medication, local physical therapy or other physical therapy, otherwise it will cause serious consequences. For example, if meniscus injury is not treated in time, it will aggravate cartilage wear, and cartilage injury is irreversible, which will bring inconvenience to patients and even lead to lifelong regret.

4. Knee bounce

Joint ringing is a normal phenomenon, because the sound produced by tendon sliding during activity is not the sound of bones, nor is there any disease in the knee joint, but if it is accompanied by pain, you should be vigilant.

There are two possibilities for joint ringing during exercise. One is normal joint activity, noise and no pain. The other is because the joint itself or its surrounding tissues are diseased, and most of them are accompanied by pain. Physiological joint noise is produced by normal joint activities and is harmless to the body. More common in beginners and people with weak muscle strength around joints. With the improvement of fitness level, muscle strength, ligament strengthening and coordination of movements, this sound will be alleviated. However, if pathological joint ring has the feeling of "clicking" and "clicking" and pain, we should make full preparations for the ringing joint before exercise, and do local * * * and hot compress after exercise to improve local blood circulation and prevent excessive growth of tissues inside and outside the joint.

5. What are the diseases that can cause joint snapping?

Joint snapping refers to the "popping" sound accompanied by joint activity, which often makes people anxious and worried about what happened.

Generally speaking, some joints snap normally. For example, the most common phenomenon is that when many people bend their fingers passively and forcefully, they omit snapping their fingers. Some people click their knees when they walk without any discomfort, but some are symptoms of disease. Diseases that can cause joint snapping are as follows: 1. The typical diseases of fingers and wrist joints are finger flick, thumb flick and styloid process stenosis of Sophora japonica. Due to long-term and rapid exertion, the muscles and waist of fingers and wrists and the bladder sheath produce symptoms, and the edematous muscle odor is compressed by the ligament on the acid sheath, forming a "gourd shape". At this time, when fingers or wrists bend and stretch hard, the gourd-shaped swollen part is forced to squeeze through the annular ligament, which will produce bull pulling action and noise, accompanied by severe pain, and the treatment is mainly local closure.

2, shoulder 1 elastic shoulder: The reason may be that the long head waist needle of the biceps brachii is inflamed, and the biceps brachii is healthy and slippery, often accompanied by hemorrhoid pain. ② Snapping scapula: It is often caused by swollen bones or osteochondroma under the chest, other nodular tumors, bone deformities on the ceramic side or shoulders, etc. There is generally no pain-related dysfunction.

3, hip joint ① Intra-articular snapping: including intra-articular osteochondromatosis, intra-articular loose body or habitual joint subluxation, often accompanied by pain. (2) Out-of-joint snapping: snapping at the greater trochanter of femur: snapping formed by thickening and tightening the cable passing through the greater trochanter of upper thigh, which is generally painless; Femoral lesser trochanter tendon, the upper thigh (psoas major) slides over the lesser trochanter, forming a click sound.

4. The common causes of knee joint are intra-articular loose bodies and intra-articular synovial diseases (synovial osteomatosis, synovial plica syndrome, etc. ), habitual bone dislocation, etc. The most common cause is meniscus injury of knee joint, which is embedded between joints and rolls between two joint surfaces with joint activity, resulting in knee joint snapping and pain. 5, ankle joint is rare, and there may be rib long and short muscle slippage.

In short, joint snapping is not accompanied by pain or other discomfort, and it is often normal or does not need sister treatment. Most of the symptoms are caused by diseases, but doctors should be invited to make a diagnosis anyway.

6. What are the disadvantages of bouncing joints?

There are three reasons for joint hiccups, 1) gas escaping, 2) joint displacement and 3) joint bone thickness caused by arthritis.

Touch surface

1) gas escape: scientists believe that there is a synovial fluid between our joints.

Liquid is used to lubricate joints. This synovial fluid contains some gases, such as oxygen, nitrogen and carbon dioxide.

Carbon. These gases form bubbles in the synovial fluid. When we stretch our joints, the gas in the synovial fluid flows quickly.

If you drop it, it will cause hiccups, because the bubble is broken.

2) Joint displacement: When we move joints, tendons and ligaments will be displaced. When tendons and ligaments return to their original positions,

You sometimes hear burps. This situation is mostly knee joint and ankle joint.

3) Joint contact surface caused by arthritis: Arthritis will destroy cartilage tissue between joints and cause joint contact.

The face is no longer smooth. In this case, joint friction will produce noise.

Is the sound produced by moving joints harmful to the body? Not necessarily.

If the movable joint burps and feels pain, you should see a doctor.

Some people like to move their knuckles to make sounds, and some research reports point out that this habit will destroy the softness between knuckles.

Tissue has weakened the grip of our fingers.

Novices often have this phenomenon, and it should be said that most of them are normal. People's joints, some parts and some angles are less active on weekdays, just like a new car, it takes a running-in period to move smoothly. Shoulder joint, in particular, is not very active at ordinary times, but in Tai Ji Chuan, all joints often do circular motion and lifting motion, which will make the "dead" joints lively, so it is inevitable to make a noise at first. However, it should be noted that beginners must pay attention to the relaxation of joints, let nature take its course, do not do strenuous exercise, and the joints can rotate as much as possible. Don't try to be brave, don't have the idea that you are not afraid of suffering and pain. Pay attention to protect joints from injury. Once the joint is damaged, it is often irreversible, which is a lifetime thing. As long as you persist, the joints will naturally open over time. Don't act in a hurry. After practicing for a month or two, if you keep practicing every day and it still rings, there may be a problem. Need to temporarily stop practicing and go to the hospital for examination.
