Tenosynovitis

Tenosynovitis is the inflammation of the fluid-filled sheath (called the synovium) that surrounds a tendon, typically leading to joint pain, swelling, and stiffness.

[6] Other bacteria linked to infectious tenosynovitis include Pasteurella multocida (associated with animal bites), Eikenella spp.

[7] Additionally, sexually active patients are at risk for hematogenous spread due to Neisseria gonorrhoeae (see infectious arthritis).

X-rays are typically unremarkable but can help rule out a broken bone or a foreign body[1] The mainstay of treatment for infectious tenosynovitis includes symptom relief, antibiotic therapy, and surgery.

[2] Most infectious tenosynovitis cases should be managed with tendon sheath irrigation and drainage, with or without debridement of surrounding necrotic tissue, along with treatment with broad-spectrum antibiotics.

Following surgical intervention, antibiotic therapy is continued and adjusted based on the results of the fluid culture.
