M00.131

Clinical Causes: Spread of bacteria through the bloodstream from a primary infection elsewhere in the body, such as the lungs or ears. Direct entry of bacteria into the joint due to trauma or penetrating injury. Existing conditions that weaken the immune system, making it easier for bacteria to infect the joint. Presence of other infections that could serve as a source of bacteria. Poorly controlled or untreated pneumococcal infections that can disseminate through the body.

Key Symptoms: Severe pain in the right wrist, often worsening with movement or pressure. Swelling and warmth around the affected joint. Redness and tenderness over the wrist area. Limited range of motion or stiffness in the wrist. Fever and chills, indicating systemic infection. General feeling of fatigue or malaise.

Diagnosis Path: Physical examination to assess swelling, tenderness, and range of motion. Blood tests, including cultures and markers of infection such as elevated white blood cell count. Joint aspiration, where fluid is drawn from the wrist joint for laboratory analysis to identify bacteria. Imaging studies like X-rays, MRI, or ultrasound to evaluate joint damage or rule out other causes for symptoms. Microbiological testing to confirm the presence of Streptococcus pneumoniae.

Treatment Protocols: Antibiotic therapy, usually with intravenous antibiotics initially, tailored based on bacterial sensitivity. Rest and immobilization of the affected wrist to reduce pain and prevent further damage. Pain management with analgesics or anti-inflammatory medications as prescribed by a healthcare professional. Drainage of joint fluid if swelling is extreme or if purulent material accumulates. Monitoring for complications or signs of systemic infection. Physical therapy after infection control to restore movement and strength.
