M65.10
Other infective (teno)synovitis, unspecified site
Clinical Classification Guidelines
Medical Intelligence & Overview
Other infective (teno)synovitis, unspecified site (ICD-10 code M65.10), refers to an infection that affects the synovial membrane of a tendon or joint, leading to inflammation. Synovitis is the inflammation of the synovial membrane, which lines joints and some tendons, providing lubrication for smooth movement. When this inflammation is caused by an infection, it is classified as infective synovitis. This condition can affect various joints or tendons throughout the body, but when the specific site is not identified, it falls under the 'unspecified site' category. Understanding this condition is essential for those experiencing symptoms or managing treatment, as timely diagnosis and intervention are key to preventing joint damage and ensuring proper recovery.
Causes & Symptoms
Clinical Causes: Bacterial infections (commonly Staphylococcus aureus, Streptococcus species) Viral infections (such as influenza, hepatitis viruses) Fungal infections, especially in immunocompromised individuals Spread from adjacent infections or systemic infections Trauma or injury leading to secondary infection Biofilm formation on prosthetic joints or tendons
Key Symptoms: Swelling around the affected joint or tendon Pain during movement or at rest Increased warmth and redness over the affected area Reduced range of motion due to stiffness or swelling Fever and chills in some cases General feeling of illness or fatigue
Diagnostic & Treatment
Diagnosis Path: Medical history review to identify risk factors or recent infections Physical examination focusing on swelling, warmth, tenderness, and range of motion Laboratory tests such as blood tests to detect signs of infection (e.g., elevated white blood cell count, ESR, CRP) Imaging studies like ultrasound or MRI to visualize inflammation and rule out other causes Synovial fluid analysis: aspiration of joint fluid for culture, Gram stain, and cell count to identify the infectious organism
Treatment Protocols: Antibiotic therapy tailored to the specific pathogen identified Drainage of infected fluid from the joint or tendon sheath if necessary Immobilization of the affected area to minimize movement and prevent further injury Pain management using analgesics as recommended by a healthcare professional Surgical intervention in severe cases to remove infected tissue or debride the area Addressing underlying causes or risk factors, such as controlling systemic infections or managing immunosuppression
