Habitual dislocation: causes, symptoms, treatment
Habitual dislocation — the bones coming from the joint capsule without returning to its original position. Trauma often happens again even at low loads, and sometimes even without a specific reason. Symptoms appear immediately after the injury. Dislocations and sprains can occur even in case of accidental movement of the hand.
The possibility and frequency of dislocations are directly dependent on the age of the patient. On the basis of statistical data it is known that people under 30 years of re-sprains occur in 80% of cases. For the treatment of such injuries in older patients often requires surgery. Dislocation of the shoulder joint occurs as a result of rupture of the joint capsule.
The structural features of the shoulder joint
Habitual dislocation is the result of a traumatic injury, resulting in the displacement of the joint surfaces relative to each other. Symptoms of injury are a little different. Secondary damage is often accompanied by sprains, which exacerbates the situation. It appears within six months after the incident, traumatic dislocation and stretching.
Dislocation has the following symptoms:
- the occurrence of pain during palpation of the joint;
- limitation of function;
- changing the length of the limb;
- possible deformation.
Considering the anatomical structure of the shoulder joint, you can thoroughly examine the principle of occurrence of the injury. The structure of the articulation of the shoulder to form 3 main parts:
- the head of the humerus;
- glenoid cavity of the scapula;
The clavicle has a significant impact on the joint itself, though not of its moving parts. The glenoid cavity is shaped like a plate. It is slightly concave, and one side serves as a support for the head of the humerus. The head of the bone resembles an Apple on a saucer and tight to the articular cavity. This structure of the shoulder joint makes the possibility of its moving in any direction. The main retainer is a ligament of the knee and rotator muscles that contribute to tension the joint capsule.
The shoulder joint more than 50% of the muscle, and this distinguishes it from other joints of the person. Features of such structure and subject to the special susceptibility of the joint to injury. Often arise sprains.
Joints according to their physical properties can be divided into two groups: stable and unstable. Stability implies the natural function of bone is to maintain a standardized position during the movements. Instability — a violation of the standard position of the bones of the joint, increasing the distance between them by any physical action. A high level of instability and there are the usual dislocation.
Causes of sprain and first aid for trauma
In contrast to the primary dislocation, which is itself a trauma and is characterized by severe pain, habitual dislocation can occur with minimal physical action. Such damage experienced by children, who often have stretching of the joints. Habitual dislocation may not even occur not to create discomfort. Some people find knee replacement often experience self-reposition.
When talking about such trauma as habitual shoulder dislocation, causes of damage can be different. There are the following main factors:
- globular head of the humerus is very large;
- scapular depression is small and flat;
- stretching of the joint capsule;
- weakness of the muscles that fix the shoulder joint.
At constant dislocations and sprains of the tendon is replaced by a colloid tissue that is more resistant to damage, resulting in deformation of the structure of soft tissues. Habitual shoulder dislocation provokes a characteristic crunch, and aching pain, then it may develop muscle atrophy. If time does not pay attention to the symptoms and do not take action, the consequences will be very serious in nature. Often the patient’s condition aggravate the strain of joints. Habitual shoulder dislocation occurs in 16% of the people who previously suffered from a traumatic dislocation. When recurring the damage appears so severe weakness in the arm that the person can no longer perform basic actions.
What to do if you sprain? It is necessary to secure the damaged joint without changing its position. Should not in any case attempt to straighten habitual dislocation and to treat sprains. The victim needs to give analginum or other strong painkillers and put on the damaged place something cold on it. Now you should wait for the paramedics to arrive. If you are unable to call an ambulance, you need to put on the damaged joint bus and take the victim to the nearest emergency room. Reduce habitual dislocation should only doctor.
Methods of treatment of a shoulder injury
Treatment by the use of various drugs is ineffective. In many cases, surgical intervention is necessary, and the sooner the better. Today the surgery is the most effective method of recovery of the knee after injury.
There are many methods of surgical intervention for the treatment of habitual dislocation. The choice directly depends on the peculiarities of the structure of the shoulder joint and the degree of its deformation. You can select the following types of possible operations:
- dermatology and plastic;
- surgery to strengthen the joint capsule;
- plastic surgery on muscles and tendons;
- surgery using graft;
- a mixed methodology.
After surgery, the arm is fixed in a stationary state with a special bandage for a period of weeks to months. During the year, you can not give much load on the arm. Even successful surgery, no doctor can guarantee complete freedom from habitual dislocation without proper rehabilitation, during which there is recovery and the gradual habituation of the muscles to increased stress.
Do not forget that surgery is a trauma to the soft tissues. Surgery can not only improve, but to radically worsen the condition of the ligaments and muscles of the shoulder joint. Many people wonder what to do with dislocation, if drugs and surgery has not brought the desired results. In such cases, one must resort to methods of influence on the muscles.
To stabilize the functionality required gradual adaptation of muscle tissue to various types of loads. The treatment method power kinesitherapy involves direct effects in the dosage volume for group of the affected muscles. This set of exercises ensures complete restoration of function of the joint without the use of drugs. Procedures are carried out at special medical simulators with a smooth transition to General physical exercise. These exercises will help prevent habitual dislocation.
Many in the rehabilitation phase starts to protect a weaker hand from unnecessary movements and minimum loads in order to avoid re-dislocation. This is a big mistake, the injured joint must be gradually developed and strengthened. It should be noted that the instability of the shoulder joint is often the result of a wrong treatment of primary dislocation.
