What are the common injuries of elbow sports?

Common sports injuries of the elbow joint include medial epicondylitis and lateral epicondylitis of the humerus.

Medial and medial collateral ligament injuries of the elbow joint, fracture of the flexure of the flexure head, fracture of the medial and external condyles of the humerus, etc., tennis elbow.

Symptoms of lateral epicondylitis of the humerus: tenderness in the lateral epicondyle of the humerus on the lateral aspect of the elbow, which is exacerbated by weight bearing. A sprain is a sudden twist of the joint that causes it to twist the ligaments and tendons that attach to the outside of the joint.

Elbow sprain is a common closed elbow injury that occurs in young adults and heavy workers.

Injuries to the elbow joint often manifest as posterior dislocations of the radius and ulnar bones, moving posteriorly and supraeriorly to the humerus. Our elbow joint is a relatively complex joint, the ligaments of the joint and the surrounding soft tissues are more complex, due to the special structure of the elbow joint, the ulnar nerve.

Run through the ulna at the back of the elbow joint.

The tunnel entered the forearm, the left elbow was dislocated, and a minor fracture was added, followed by joint reduction. For example, repeated shots can cause tendon injuries in the elbow, resulting in tennis elbow and golfer's elbow. One of the symptoms is a gradual increase in pain, anterior Montessori fracture dislocation, and lateral views suggesting a comminuted fracture of the proximal ulna with the radius.

Anterior dislocation. Supracondylar fractures can account for half of a child's perielbow fractures and are often caused by a fall on the arm.

Radial collateral ligament: located lateral to the capsule. It originates from the lateral epicondyle of the humerus, divides into two bundles and wraps around the radial head anteriorly and anteriorly, ending at the anterior and posterior borders of the radial notch of the ulna.

Lateral epicondylitis of the humerus is a cause of pain. Inflammation usually arises due to overuse of the tendons in the elbow, usually due to repeated movements of the wrist and arm.

The flexion of the elbow joint should reach at least 120 degrees or more, so as not to affect daily actions such as combing hair, answering **, and bathing. In the position of the olecranon often occurs , bursal cysts.

Above the olecranon's beak, it is very easy to occur, and the fracture and injury experience near the elbow joint is also one of the reasons for the stiffness of the elbow joint.

For example, medial upper malleolitis, sometimes epicondylitis outside the humerus, sometimes there will be this joint dislocation, sometimes there will be fractures or ligament strain, so you must do a good job of warm-up exercises, and you must pay attention to protect yourself, and you can also wear some protective gear.

Muscle strain, lateral pain, inflammation, sprains, and external soft tissue injuries are common.

Nowadays, people's living conditions are getting better and better, and the quality of life and health requirements are getting higher and higher, many people will carry out all-round exercise exercises to enhance their resistance, but many people will cause limb injuries because of improper methods or excessive force when exercising, and elbow joint injury is a relatively common injury. Common injuries to elbow joint movement include inflammation of various bones in the elbow joint, or more serious ligament strains in the elbow joint, and even fractures. <>

1. What is the elbow joint?

Elbow is what we call the elbow joint, the elbow joint is a joint composed of the lower end of the humerus and the upper end of the radius ulna, of which there are three very important joints: the humeraldial joint, the humeral-ulnar joint, and the radial-ulnar joint. These joints are the most commonly used parts of the human body, and they are under the main force during exercise, so they are very susceptible to injury.

2. Is elbow injury good**?

Because the direction of movement done by the elbow joint often leads to inflammation of the elbow joint, because the elbow joint repeatedly rubs and squeezes during movement, there is a bursa inside the joint, which causes aseptic inflammation. If it is aseptic inflammation, it is more convenient, and only medical injections need to be carried out at the site of inflammation, which can be targeted**, but if it is a joint strain, ligament strain or fracture caused by exercise, then you need to be admitted to the hospital**. According to the development of modern medicine, it is better to damage the elbow joint, but it is only a method, mainly to rely on maintenance.

3. How to prevent elbow injury?

Elbow injuries are the same as other joint injuries, if it is an injury caused by exercise, then you need to do a good warm-up exercise before exercising and fitness, do not suddenly put too much pressure on the joint, and have a slow adaptation process. Exercise should be carried out slowly, and planned training should be carried out within the range that the body can bear, and do not train blindly alone, otherwise it is easy to cause joint damage.

From the above points, it can be seen that there are many common injuries to the elbow joint, and it is necessary to pay more attention to maintenance in daily sports and life.

Common elbow injuries are related to joint dislocation, joint deformity, arthritis, joint stiffness, joint capsule, ligament injury, elbow instability, fractures, etc. The most common elbow injury is elbow dislocation.

Joint fractures, joint dislocations, ligament injuries, medial epicondylitis, lateral epicondylitis of the humerus, etc., we should be careful not to do too much intensity and difficulty when exercising, and do relaxation exercises to avoid the above situations.

1. Medial epicondylitis: slightly swelling on the outside of the joint, positive tenderness sign at the lateral epicondyle 2. Elbow fracture: limited joint movement, and subcutaneous bruising of the joint can occur in severe cases 3. Elbow dislocation: joint deformity, limited flexion activity.

Preamble: If the joint is in a state of motion all the time, its range of motion exceeds the maximum range that the body can bear, it is very easy to cause injury. There will be a certain degree of pain after an elbow injury, which will have a certain impact on life and work.

Therefore, it is very important to protect your elbow joint, and I will share with you what and which ways to avoid elbow joint injury. <>

Elbow injuries tend to occur in sports such as badminton and golf, and the movements that others are suitable for you may not be suitable for, so when you have elbow pain, you should immediately change to another job. For fitness people who do heavy training regularly, they may feel shoulder pain. If you continue to do bench press, it will exacerbate the symptoms of shoulder inflammation.

It can be replaced with a rope chest clamp or a dumbbell bird, although the effect is not the same, but it is a good relief of body pain. <>

Before we do any exercise, we have to do a good warm-up training. Warm-up is very important, but in real life, there are many people who do not know or do not warm up enough, which will cause a certain degree of strain during sports. If you do 5 10 minutes of aerobic exercise before doing heavy strength training, you should fully stretch all parts of the body during the warm-up, and also do a certain degree of stretching after the exercise.

In many fitness exercises, the joints are required to be locked once per movement, but in multi-joint exercises that train the chest and legs, if they are locked, the weight will be transferred to the joints. If you have the habit of resting during movements, your joints will be under more stress. If you feel pain during exercise, it is possible that the joint is locked, and the amplitude of the movement can be reduced.

Although the effect will be reduced, it will also avoid elbow injury.

You can wear knee pads on the joints, remember to massage after exercise, and go to the hospital for a physical examination, so that you can avoid it.

Exercise moderately to avoid excessive exercise that can cause damage to the elbow joint. Warm up before exercise, so that the elbow joint can be fully moved, and you can avoid the damage to the elbow joint caused by excessive exercise.

I think the best thing to do is to wear elbow pads when exercising, so that you can effectively avoid elbow injuries.

Correct answer: BCD

Composition:

1. Humeral-ulnar joint: a trochlear joint composed of the humeral trochlea and the ulnar trochlear notch.

2. Humerioradial joint: The ball-and-socket joint composed of the small head of the humerus and the concave joint of the radial head should have three directions of movement, but due to the limitation of the ulna, it cannot do adduction and abduction exercises.

3. Proximal radial-ulnar joint: a cylindrical joint composed of the annular articular surface of the radius and the radial notch of the ulna.

Mode of movement: The elbow joint is a typical compound joint, the front and back of the joint capsule are thin and loose, and the sides are tense.

All elbow ligaments do not conform to the radius, thus ensuring that the radius can move both internally and externally around the vertical axis. From the perspective of the overall movement of the elbow joint, there are two axes of motion, that is, flexion and extension movement around the frontal axis, which is common to the humeral-ulnar joint and the humeral-radial joint, and can be used for intrapronation and pronation movement around the vertical axis, and this axis of motion is common to the brachioradial joint and the proximal radial-ulnar joint.

Composition: lower end of the humerus, upper end of the ulna of the radius.

Humeral-ulnar joint: trochlear humerus, ulnar trochlear notch.

Humeroradial joint: The humeral head is small, and the radial head joint is concave.

Proximal radial-ulnar joint: radial notch of the ulna, annular joint fovea of the radial head: three joints in one joint capsule, compound joint, radial collateral ligament and ulnar collateral ligament on both sides, weak anterior and posterior, radial annular ligament around the radial head, the weakest posterior wall, easy to dislocate posteriorly and superiorly.

Movement: flexion and extension.

The main muscles responsible for elbow flexion are biceps contraction and triceps relaxation;

The main muscles responsible for elbow extension are triceps contraction and biceps relaxation.

Mainly flexion and extension exercises. The elbow joint is a composite joint. It is composed of three single joints: the humeral-ulnar joint, the brachioradial joint, and the proximal radial-ulnar joint, which are jointly enclosed in a joint capsule.

The main forms of elbow joint movement are flexion and extension movements, followed by the joint movement of the proximal radiulnar joint and the distal radiulnar joint to complete the pronation and pronation movements of the forearm. The average flexion and extension of the elbow is 135-140°.

Because the joint axis of the humeral trochlea is inclined inward and downward, when the forearm is extended, between the forearm and the central axis of the upper arm, an outward deflection angle is formed, which is called the carrying angle, about 15 °. Involved muscles:

a.The upper arm muscles mainly move the elbow joint and are divided into two groups: anterior and posterior. The anterior group is the flexor muscle, mainly biceps brachii and brachialis muscles; The posterior group is the extensor muscle, mainly the triceps.

1) Biceps brachii contraction mainly flexes the elbow joint and supinates the forearm, which can also assist in flexing the shoulder joint.

2) The brachii muscle is located deep in the biceps brachii. Flex the elbow joint during contraction.

3) Triceps brachii starts with three heads. When contracting, the elbow joint is mainly extended.
