M68.0: Synovitis and tenosynovitis in bacterial diseases classified elsewhere

Synovitis and tenosynovitis are inflammation-related conditions that affect the synovial membrane. Generally, this membrane cushions and lubricates the places where muscles and tendons glide alongside bones, such as joints. When the synovial membrane is affected by an inflammation process, such as in cases of synovitis, it can cause pain, swelling, and difficulty moving the affected area. Tenosynovitis, on the other hand, specifically involves inflammation of the fluid-filled sheath (the synovium) that surrounds a tendon. The particular term 'Synovitis and tenosynovitis in bacterial diseases classified elsewhere' actually denotes that these inflammation processes are caused by a bacterial infection that is primarily based in another part of the body but has led to these symptoms in the joints or tendons. The symptoms, progression, and affected systems may vary according to the source of the bacterial infection.
