M00.84
Arthritis due to other bacteria, hand
Clinical Classification Guidelines
Inclusion Terms
- Arthritis due to other bacteria, metacarpus and phalanges
Medical Intelligence & Overview
Arthritis due to other bacteria, specifically affecting the hand, refers to joint inflammation caused by a bacterial infection. This condition primarily targets the small joints in the fingers and the surrounding structures of the metacarpus and phalanges. It differs from typical forms of arthritis, such as osteoarthritis or rheumatoid arthritis, because the inflammation stems from an infectious bacterial source. Recognizing and understanding this condition is important because bacterial arthritis can lead to joint damage if left untreated.
Causes & Symptoms
Clinical Causes: Bacterial invasion through a wound or cut near the hand Spread of bacteria from other parts of the body via bloodstream (bacteremia) Direct infection during surgical procedures or injections in the hand Immune system suppression, which can facilitate bacterial growth Pre-existing skin infections that introduce bacteria into joint tissues
Key Symptoms: Severe joint pain localized in the hand Swelling and tenderness around affected joints, especially in the fingers Redness and warmth over the affected joint Limited range of motion or stiffness in the fingers or hand Fever and general feeling of illness in some cases Sometimes, an audible crack or popping sound during movement Possible presence of pus or fluid collection in the joint area
Diagnostic & Treatment
Diagnosis Path: Physical examination to assess swelling, warmth, and mobility Imaging tests such as X-rays or ultrasound to evaluate joint damage Fluid aspiration: extracting joint fluid for laboratory analysis to identify bacteria Blood tests to detect signs of infection and inflammation, such as elevated white blood cell count or C-reactive protein Microbiological cultures to identify the specific bacteria responsible Serologic tests if systemic infection or specific bacteria are suspected
Treatment Protocols: Antibiotic therapy tailored to the specific bacteria identified through cultures Drainage of infected joint fluid, often via needle aspiration or surgical procedure Rest and immobilization of the affected hand to reduce strain and inflammation Pain management with analgesics or anti-inflammatory medications Physical therapy after infection control to restore mobility and strength Surgical intervention in severe cases to remove damaged tissue or drain abscesses
