M00.15

Clinical Causes: Infection with Streptococcus pneumoniae bacteria, which can spread through the bloodstream from other parts of the body. Direct entry of bacteria into the hip joint through penetrating injuries or surgeries. Spread from nearby infected tissues or skin infections. Weakened immune system, making the body more susceptible to bacterial infections. Pre-existing health conditions such as rheumatoid arthritis or other forms of immunosuppression.

Key Symptoms: Severe pain in the hip that worsens with movement or pressure. Swelling and warmth around the affected joint. Reduced range of motion in the hip joint. Fever and chills accompanying the joint symptoms. General feeling of malaise and fatigue. Potential redness over the joint area.

Diagnosis Path: Physical examination to assess pain, swelling, and range of motion. Blood tests to identify signs of infection, such as elevated white blood cell count and inflammatory markers. Imaging studies like X-rays or MRI to evaluate joint damage and inflammation. Joint aspiration, where synovial fluid is extracted for analysis to identify bacteria, cell count, and other markers. Microbiological cultures from joint fluid to confirm the presence of Streptococcus pneumoniae.

Treatment Protocols: Antibiotic therapy using antibiotics effective against Streptococcus pneumoniae, often administered intravenously at the start. Rest and immobilization of the affected hip to reduce pain and prevent further damage. Pain management with medications such as NSAIDs or acetaminophen. Drainage of joint fluid if necessary to relieve pressure and remove infected material. Surgical intervention in severe cases, which may include joint cleaning (debridement) or hip replacement. Monitoring and follow-up to assess response to treatment and prevent recurrent infections.
