- Dislocation of the blade: it is necessary to clarify the situation
- Shoulder Joint
Damage to the joints of the upper limb girdle are very common. Sometimes you can hear about such a diagnosis as a dislocated shoulder blade, but officially it does not exist. Usually they mean the dislocation of the acromioclavicular or glenohumeral joint.
The structure of the upper limb girdle
Blades, collarbones and muscles, which provide support and movement of the upper limbs, together form the shoulder girdle. Shoulder - a steam room flat triangular-shaped bone. On the rear surface is bone protrusion, which is called scapular spine. Its height from the inner to the outer edges gradually increased, and scapular spine goes into the acromion - the large bone process. He, along with the joint end of the clavicle is involved in the formation of the acromioclavicular joint.
Just below is glenoid cavity. It is an impression, which is connected with the head of the humerus. Outside the joint capsule is covered and strengthened by ligaments and muscles.
Dislocation of acromioclavicular joint
This dislocation often occurs in the fall on the shoulder or when you hit the collarbone. The clavicle is connected to the shoulder blade with the help of the acromioclavicular and clavicular-coracoid ligament. In cases where the breaks only the first of them, the dislocation is incomplete, and if at the same time violated the integrity of both - complete.
If the clavicle is displaced above the acromion process, such a dislocation called nadakromialnym. When podakromialnom dislocation of the outer end of the collarbone is below the acromion. The latter type of displacement of the articular surfaces of bones is very rare.
There are a number of features that are typical for a full dislocation of the acromion (blade) end of the clavicle. Man motion in the shoulder joint, as well as probing Dr. acromioclavicular joint pain. Girdle side damage looks shorter. The outer end of the clavicle acts as a step, and moves easily back and forth.
Symptom "keys" - an important sign of dislocation of the clavicle
Dislocation of the clavicle: injury
. When pressed on the end of the acromion, it is easy to return to his seat. But if you let go of the clavicle, the outer part of it, as a key, rapidly rises.
In order to confirm the diagnosis, conduct X-ray examination. When taking pictures the patient should stand. When it is necessary to distinguish between complete dislocation from incomplete do symmetric radiographs of both the acromioclavicular joint.
Dislocation easy to reduce a, and then it is very important to keep the clavicle in place. Use a variety of dressings (usually plaster), while the region acromioclavicular joint impose wadding-lock. The term immobilization (creating stiffness in the joints) of about six weeks.
When chronic sprains
Dislocation - Prevention and Treatment
and in cases where conservative treatments have been unsuccessful, surgery is performed. The surgeon made of synthetic materials (silk, Dacron, nylon), autotkaney (tissues that belong to the patient) or allotkaney (taken from the body of another person) forms a new bond. After that, for six weeks in a plaster cast is applied.
Traumatic dislocation of the shoulder usually occur during the fall forward or assigned to an elongated arm. The displacement of the articular surfaces of the humerus and scapula relative to each other can also occur if a person falls back on the lag hand.
Humeral head may move in different directions with respect to the glenoid cavity of the scapula. Depending on this dislocation is divided into front, back and bottom.
Signs of dislocation occur immediately after the injury that led to its emergence. Girdle the affected hand is omitted, and the patient tilts his head to the side damage. Man complains of pain and the inability of movement in the shoulder joint.
Damaged hand seems longer, she bent at the elbow, and is in the lead. In order to create peace limb, the patient holds it with his good hand.
When probing the area of joint doctor discovers that the head of the humerus is in an unusual position. He must also determine whether the motion has not been violated, and skin sensitivity below the injury site, and check the pulse on the affected arm. It is necessary to find out whether the injured nerves and blood vessels.
Radiography - an important method of examination of the patient by means of which put the final diagnosis. We can not reduce a dislocation prior to this study, since it is necessary to clarify whether there are fractures of the scapula and the humerus.
Dislocation should be eliminated immediately after the establishment of the final diagnosis. This manipulation is performed under local or general anesthesia. There are many methods by which you can straighten a dislocated shoulder
Dislocated shoulder - do not try to put everything in place
. The most famous of these are ways to Kocher, Hippocrates, Mota, Janelidze, Chaklin, Meshkov.
If you fall between the joint surfaces, soft tissue, it is called a dislocation nevpravimym, and can not be eliminated by conservative methods. In this case, the arthrotomy - opening of the cavity of the shoulder joint. The surgeon then removes the obstacle and eliminate a dislocation.
No matter what method was vpravlen dislocation, impose on a limb plaster Longuet month in young people, and for three weeks in older age. In the elderly, instead of using the cast kosynochnuyu.
Patients prescribed painkillers and UHF on the shoulder joint. Before removing plaster bandage person should perform active movements in the joints of the hand. After immobilization (stiffness) of the shoulder joint is not necessary, it is advisable to engage in physical therapy.
Acromioclavicular dislocations and shoulder joints require the necessary examinations and early treatment. Therefore, the appearance after an injury of the upper limb dislocation symptoms should seek emergency medical care.
