M46.43

Clinical Causes: Bacterial infection, most commonly involving Staphylococcus aureus Spread from nearby infections such as vertebral osteomyelitis Hematogenous spread from infections elsewhere in the body Trauma or spinal procedures introducing pathogens Weakened immune system, increasing susceptibility to infections

Key Symptoms: Severe neck or upper back pain that worsens with movement Fever and chills, indicating systemic infection Local tenderness over the affected spine segment Limited range of motion in the neck or upper back Possible neurological symptoms such as numbness, weakness, or tingling if the infection compresses spinal nerves General malaise and fatigue

Diagnosis Path: Magnetic Resonance Imaging (MRI): The most sensitive tool for detecting discitis, showing disc space narrowing, edema, and soft tissue involvement Computed Tomography (CT): To assess bone destruction and rule out other structural issues Blood tests: Elevated markers of inflammation such as ESR (erythrocyte sedimentation rate) and CRP (C-reactive protein), along with blood cultures to identify causative bacteria Biopsy: Sometimes necessary to obtain tissue samples for culture and histopathology Other laboratory tests: To evaluate for underlying diseases or immune suppression

Treatment Protocols: Antibiotic therapy: Usually initiated intravenously, tailored based on culture results, and continued for several weeks to months Pain management: Utilizing medications such as NSAIDs or analgesics to control discomfort Rest and immobilization: To reduce strain on the infected spine segment Surgical intervention: In cases of spinal instability, abscess formation, or neurological impairment, procedures may involve debridement, drainage, or stabilization Monitoring and follow-up: Regular imaging and laboratory tests to assess treatment efficacy and resolution of infection
