M46.49
Discitis, unspecified, multiple sites in spine
Clinical Classification Guidelines
Medical Intelligence & Overview
Discitis is an uncommon but serious condition characterized by inflammation of the intervertebral discs in the spine. When it affects multiple sites within the spine, it can cause significant discomfort and mobility issues. The ICD-10 code M46.49 specifically refers to unspecified discitis involving more than one location in the spine, highlighting the need for medical evaluation and management to address this condition properly.
Causes & Symptoms
Clinical Causes: Bacterial infection, most commonly Staphylococcus aureus Spread of infection from nearby tissues or other parts of the body Infections following spinal surgery or invasive procedures Hematogenous spread from other infected sites in the body Less commonly, fungal or other atypical infections
Key Symptoms: Severe localized back pain that worsens with movement Fever and chills, indicating infection General malaise and fatigue Tenderness in affected spinal regions Potential neurological symptoms if nerve compression occurs, such as tingling or weakness Reduced range of motion in the spine
Diagnostic & Treatment
Diagnosis Path: Medical history and physical examination focusing on pain patterns and systemic symptoms Blood tests to detect signs of infection, such as elevated white blood cell count, C-reactive protein, or erythrocyte sedimentation rate Imaging studies including MRI scans, which provide detailed images of disc and vertebral inflammation Biopsy of the affected disc tissue or vertebrae to identify the causative organism Bone scans or other nuclear imaging techniques if needed
Treatment Protocols: Prolonged courses of antibiotics tailored to the identified pathogen, often lasting several weeks to months Rest and activity modification to reduce spinal strain Pain management through medications such as analgesics or anti-inflammatory drugs Immobilization with braces or supports to stabilize the spine Surgical intervention may be necessary in cases with spinal instability, abscess formation, or neurological impairment Follow-up care with regular imaging and laboratory tests to monitor treatment response
