M00.139

Clinical Causes: Spread of bacteria through the bloodstream from a primary infection elsewhere in the body Direct inoculation of bacteria into the joint due to injury or surgical procedures Compromised immune system, increasing susceptibility to infection Existing infections in other parts of the body, such as pneumonia or meningitis, which can disseminate bacteria

Key Symptoms: Sudden onset of severe pain in the wrist joint Swelling and warmth around the wrist Redness and tenderness over the affected joint Stiffness and decreased range of motion Fever and general malaise in some cases Possible pus formation in or around the joint in advanced cases

Diagnosis Path: Healthcare providers typically use a combination of medical history, physical examination, and laboratory tests to confirm pneumococcal arthritis. Diagnostic procedures may include: - Joint aspiration: extracting synovial fluid from the wrist for analysis to identify bacteria - Blood tests: detecting signs of infection and inflammation - Imaging tests such as X-rays or MRI: to assess joint damage and rule out other causes - Microbiological cultures: to specifically identify Streptococcus pneumoniae as the causative organism Timely diagnosis is crucial to prevent joint damage and systemic complications.

Treatment Protocols: Treating pneumococcal arthritis generally involves a combination of antibiotics and supportive care: - Antibiotic therapy: directed at Streptococcus pneumoniae, often administered intravenously initially, then orally as appropriate - Joint drainage: relieving pressure and removing infected fluid from the wrist - Rest and immobilization of the affected wrist to reduce stress on the joint - Pain management: using medications to alleviate discomfort - Monitoring for complications: such as joint destruction or spread of infection In some cases, surgical intervention may be necessary to debride the joint or address severe damage. Follow-up care may include physical therapy to restore function.
