Transient: A clinical symptom or sign that occurs once or several times in a short period of time, often with an obvious trigger, such as after eating a certain food, taking a certain medication, receiving a certain clinical treatment, or other factors that affect the body. With the removal of the trigger, this symptom or sign quickly disappears. Synovitis: The inner layer of the joint capsule is lined with a very thin layer of tissue called the synovial membrane. Under normal conditions, the synovial membrane secretes a small amount of fluid, the main function of which is to make the joint surface more slippery when it is ground, as if it were lubricated in a machine. When there is an irritant inside the joint, whether bacterial, physical or chemical, the synovial membrane reacts first, causing congestion and edema, and leaks fluid, causing the joint capsule to swell and manifest itself as a swollen joint. Over time, this becomes chronic synovitis. Therefore, synovitis is the result of congestion and swelling and fluid accumulation due to obstructed microcirculation. It is important to minimize the frequency of pumping injections, as too many pumping injections can stimulate fiber proliferation in the subsynovial connective tissue group, as well as aging of synovial tissue, which can significantly reduce the regeneration and repair ability of synovial tissue and make treatment more troublesome. The bursa is a reservoir of oil, which is used to refuel the skeletal tendons, the purpose of which is to increase lubrication and reduce friction, if there is water, the water dilutes the synovial fluid and does not play a lubricating role, at this time, strenuous activity will produce skeletal friction and eventually damage the bones. The principle of treatment is to regulate and unblock the obstructed microcirculation, as long as the obstructed microcirculation is unblocked, the bursa secretion synovial fluid output and absorption to achieve a balance can be recovered. There are many causes, one of the more common causes is complications caused by viral infections (such as viral colds). Viral infections in the body result in varying degrees of immune response, which varies from person to person. Increased congestion and edema of the synovial membrane is one of the manifestations and is self-limiting. Most cases heal in 1 to 2 weeks. Sometimes parents may find that their child suddenly walks with a limp, asks about the phenomenon of leg numbness, and has symptoms of leg weakness and fever when they are sick, but when they go to the hospital for an X-ray, the film suggests normal. If diagnosed by a doctor it will be found to be synovitis of the hip joint. It is often overlooked by parents because the symptoms are not very obvious. Symptoms: Transient hip synovitis, also known as hip misalignment, slipping crotch, long foot wind, etc., mostly occurs in children aged 3 to 10 years old, because the development of the femoral head is still immature, the joint capsule is more relaxed, once the lower limb is excessively abducted, or jumped from a high place downward, or walking unsteadily to cause lower limb external booth sprain, or excessive running and jumping strain to stretch the joint capsule, or the joint capsule is squeezed and cause hip synovitis The symptoms of transient hip synovitis are as follows: if the injury is acute, hip pain occurs immediately after the injury, sometimes there is slight swelling of the soft tissue on the front side of the hip joint and walking is difficult, but some children just feel discomfort in the affected limb and walk with a limp after the injury, and the pain in the affected limb gradually increases after 2~3 days, and the limp becomes more and more serious when walking. The pain increases with activity, and because of the pain, the child’s pelvis is often tilted to the affected side, so if you compare the lower extremities, you will find that the lower extremity on the affected side is slightly longer. A small number of children have a combination of low fever. Most of the pressure points are in the groin of the affected hip joint, or in the posterior pear-shaped muscle. The majority of the pressure points are in the groin of the affected hip, or in the posterior pear muscle. Prevention: Transient synovitis mostly occurs in children aged 3 to 10 years old, as parents of children should pay attention to the amount of children’s activities, do not overload the activities to avoid overexertion due to the large amount of activity caused by damage to the joint capsule, in this age group of children because the development of the femoral head is still immature, the joint capsule is loose, and children’s characteristics are fond of jumping, especially from a high place down jumping, its height sometimes exceeds The height is sometimes higher than the child’s own ability to adapt, which can easily damage the synovial membrane of the hip joint. Therefore, children should always be taught not to jump down from high places at will, and the amount of activity for children should be properly controlled. It is also important to keep children warm in winter to avoid wind chill or cold to protect their health. Treatment: At present, the treatment of transient hip synovitis in children generally adopts bed rest, skin traction and other conservative therapies, and Chinese medicine still has manipulative treatment. The main purpose is to reduce the pressure on the hip joint to prevent long-term pressure problems with blood supply to the femoral head.
