Common noninfectious tenosynovitis are: stenosing tenosynovitis, intersection syndrome, extensor pollicis longus (EPL) tenosynovitis, de Quervains and fourth compartment tenosynovitis. Diagnosis
Diagnosis of tenosynovitis is typically made clinically after a thorough patient history and physical exam. Aspirated fluid can also be cultured to identify the infectious organism. X-rays are typically unremarkable but can help rule out a broken bone or a foreign body

Treatment
The mainstay of treatment for infectious tenosynovitis includes symptom relief, antibiotic therapy, and surgery. Early recognition of the disease with early initiation of antibiotics are important for better range of movement of the affected finger. Minimally invasive procedures into the flexor tendon sheath such as catheter irrigation give better outcomes (74% chance of good outcome) when compared to open surgery (26% chance of good outcome). However, wound irrigation with antibiotics has no clear benefits. 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. In severe cases, amputation may even be necessary to prevent the further spread of infection. Following surgical intervention, antibiotic therapy is continued and adjusted based on the results of the fluid culture. Prognosis
The earlier the condition is identified, the better the chance of getting full range of motion of the finger. However, finger stiffness, Boutonniere deformity, deep space infection, tendon necrosis, adhesions, persistent infection, and need for amputation of the finger can occur. Tendon adhesion and finger stiffness are caused by the violation of the flexor tendon sheath.
