What is the Synovitis flexor?
flexor tenosynovitis (FT), also called the synovitis of the tendon of flexor tendons or synovitis of flexor, concerns inflammation of the synovial cloak and the tendons of the fingers of the hand. This is usually due to infection, but this condition can also cause acute and chronic inflammatory pathophysiological conditions such as arthritis and diabetes. The diagnosis of infectious or septic ft is dependent on four canales, which includes a finger placed in a slight flexion, swelling, tenderness along the vagina of flexor tendons and pain caused when the affected number is passively widespread. This inflammation can quickly destroy the functional capacity of the person's fingers, so it is considered to be one of the orthopedic emergencies. Proper treatment should be started immediately. Other causes include wound bite and hematogenic or blood spread of bacteria from other infected areas of the body. Trauma disrupts normal anatomy and physiology of the hand, allowing native skin flora, such as Staphylococcus and Streptococcus, attacking tissues under the skin. MostIna cases of infectious flexor synovitis are caused by Staphylococcus aureus, but there are many others. Studies show that when flexor tenosynovitis is diagnosed with magnetic resonance (MRI), it strongly predicts early rheumatoid arthritis. People who have diabetes are also exposed to a higher risk of multiple digits affected by the synovitis of the flexor.
tendon shells have both the inner layer, called the visceral layer and the outer layer called the parietal layer. The visceral layer is closely approximated to a flexor and the space between these layers called synovial space, containing synovial fluid. Based on this anatomical organization, infection of the tendon vagina is called an infection of the enclosed space. When the pus accumulates in the tendon of the tendon of the flexor tendon, the pressure increases and leads to a reduction in blood flow to the area or ischemia. With the occurrence of tendon ischemia is the risk of necrosis and burstInstead of high and may lead to loss of flexor function.
non -infectious flexor synovitis occurs when certain substances such as amyloid or crystals are proliferated in the joint space. These substances interfere with nearby tendons, leading to swelling and pain. With recurring microtrauma or overuse syndrome, the tendon tissue cannot adapt to chronic damage, leading to inflammation, proliferation and ripening.
A person with infectious flexor tenosynovitis often complains about symptoms of pain, redness and fever and physical findings include Kanavel's signs. Kanavel signs may not be present if the patient is at an early stage of the disease, has recently taken antibiotics, chronically infected or has an immunocompromised condition. A person with a non -infectious flexor synovitis often has joint swelling as an initial symptom and complains of limited movement and pain.
Treatment of this condition includes medical therapy, including intravenous antibiotics, increased affected areas and rehabilitation with scopeMovement (ROM) exercise. People who are immunocompromised, have diabetes or have a flagrant pus in their tendons must undergo surgical treatment. Surgical treatment involves incision to the affected area, pus drainage, irrigation, tiles and increases, as well as concurrent antibiotic therapy.
