Hygroma wrist joint: signs and treatments
Hygroma wrist joint is characterized by the formation of a small hernia SAC containing synovial fluid. In most cases this disease affects the dorsum of.
The structure of the wrist joint
I believe that the wrist joint has a complex anatomy among all other joint entities. The wrist bones are small, just 8 of them. They are joined by the radial bone, the second side is combined with the metacarpal bones. By ligaments to the carpal bones stick together and the brush moves in either direction. Merging together, the ligaments form a capsule, which are the joints of the wrist. It contains synovial fluid, which during movements of the articular surface lubricated.
Almost every move made with a brush, pass the tendons of the muscles. When you increase the size of hygroma wrist joint surrounding tissue, including ligaments and tendons apart. This tumor is considered benign tumor (cyst) containing a viscous gelatinous fluid.
The wrist joint or Palmar surface of the ganglion cyst affects quite rare. The place of its localization in these cases often becomes a projection of the radial artery.
Factors that could cause hygroma
The most common causes of tumors are:
- excessive load on the brush;
- injuries of the wrist;
- secondary injury (often seen in athletes);
- the postoperative course.
Generally, the occurrence of hygroma wrist joint due to thinning of the articular capsule. The reasons for this can be different factors — from degenerative changes to a different kind of damage. As a result of herniation of fabric brushes are damaged. Affected inner layer of the capsule is gradually replaced by synovial fluid, while the surrounding tissues begin to spread out.
If the patient is not promptly turned to the doctor, after some time, a ganglion cyst of the brush increases in size. It should be noted that the limited load can significantly reduce the production of synovial fluid and stop the growth of the hernia. In some cases, the load reduction is sufficient to ensure that all the symptoms gradually disappeared.
Signs and diagnosis of the disease
Symptoms of the hand and wrist joint often arise suddenly, the size of the hernia may for two days increase to 2 see Often, the disease develops over several years. Many patients notice a tumor on the brush only with the appearance of pain in the tissues that surround it. The ganglion cyst itself is not dangerous and does not have any effect.
The dangerous development of the disease in children? Special danger to the health of the child is not a ganglion cyst, but neglect of timely treatment is still not worth it. It is very important to identify the cause of the tumors. Perhaps disease brought previously injured wrist. If the child complains of pain in the region of the radiocarpal joint, should immediately contact the doctor.
Diagnosis of disease is conducted by the surgeon. For more information, in some cases, prescribe an MRI or ultrasound. Before you make a decision about treatment, the specialist conducts a thorough examination of the patient. However, he is guided by several principles.
In some cases treatment of the disease is through surgical intervention, but conservative methods are often sufficient. Before you apply a particular tool in the fight against disease, the doctor analyzes all its pros and cons.
Methods for treating hygromas
In identifying the disease at early stages are most often needed is the conservative methods of treatment. They include such events.
Several years ago, the treatment of hygroma was her crush. To call the procedure is not harmful, intra-articular fluid poses no danger to nearby tissues. Despite this, to date, doctors do not recommend to use this method of treatment because in 90% of cases after some time the hygroma had formed again. This leads to fast coalescence of the edges of the capsule, which again accumulates synovial fluid.
Treatment with glucocorticoid is quite effective. But this technique only if the disease is diagnosed at an early stage (size hygroma not more than 1 cm). Especially in the area of the hernia is administered local anesthesia. Then pierce the capsule and suck out the joint fluid with a syringe. Then the syringe is changed (not pulling with needle) and inject a glucocorticoid. At the end of the procedure on top of the wrist joint impose tight bandage. This is to ensure that the edges of the hernia healed. Wear the orthosis needs for over 5 weeks. The presence of a pressure bandage is necessary, otherwise, when the movement in the wrist joint will again stand out and accumulate synovial fluid. Typically, such a process leads to recurrence of the disease.
If the size of hygroma exceeds 1 cm, or education has a cellular structure consisting of several capsules, surgical intervention is necessary.
Removal of tumors by surgery
Because the hand has a complex anatomy, surgery must be carried out only by a specialist in this field. Surgery is required in advanced stages of the disease when movements are limited because of capsules of large size. Before surgery, the patient is administered local or conduction anesthesia.
Laser surgery to remove the capsule does not differ from standard surgical intervention. The advantage of this procedure is that it is more gentle. Breaking the skin with a laser, expose the capsule, then remove.
Remove the capsule synovial fluid through a small incision. While the surrounding tissue should be gently separated. Stitched outlet, the experts carefully monitored to ensure that the joint remains liquid. Over the sutured incision impose a sterile bandage, the joint is fixed with an orthosis. After 2 weeks the stitches are removed.
To guarantee the exclusion of relapse is practically impossible, a method for treating hygromas in this case does not matter. The main conditions are competent actions of the physician and adherence to all recommendations during the rehabilitation period. Significant role played by the individual characteristics of the patient.
