M00.111

Clinical Causes: Spread of pneumococcal bacteria through the bloodstream from a primary infection elsewhere in the body, such as pneumonia or sinusitis. Direct inoculation of bacteria into the shoulder joint due to trauma, surgery, or invasive procedures. Weakened immune system making the individual more susceptible to bacterial infections. Pre-existing joint disease or conditions that compromise joint integrity.

Key Symptoms: Intense pain in the right shoulder that worsens with movement or touch. Swelling and redness around the shoulder joint. Limited range of motion, making it difficult to move the arm freely. Warmth and tenderness over the affected joint. Fever and chills if the infection spreads or is severe. Possible general feeling of illness or fatigue.

Diagnosis Path: Physical examination to assess joint swelling, tenderness, and functionality. Blood tests to detect signs of infection and inflammation, such as increased white blood cell count or elevated C-reactive protein. Joint fluid analysis: A sample of synovial fluid is extracted via joint aspiration to identify bacteria, especially Streptococcus pneumoniae, under laboratory analysis. Imaging tests like X-rays, ultrasound, or MRI scans to evaluate joint damage and rule out other causes of joint pain.

Treatment Protocols: Prompt administration of intravenous or oral antibiotics that target Streptococcus pneumoniae. Drainage of the infected joint fluid if necessary, to remove pus and reduce pressure. Pain management using medications such as NSAIDs or other analgesics. Immobilization of the shoulder temporarily to reduce strain and promote healing. Physical therapy may be needed after the infection subsides to regain strength and mobility. In severe or persistent cases, surgical intervention might be required to remove damaged tissue or perform joint repair.
