Percivall Pott: tuberculous spondylitis

Area of Science:

• Orthopedics
• Infectious Diseases
• Radiology

Background:

• Tuberculous spondylitis (Pott's disease) is a spinal infection causing kyphotic deformity.
• While tuberculosis incidence has decreased in industrialized nations, extrapulmonary cases persist, affecting adults more commonly in Europe and North America.
• Pott's disease often results from late reactivation of latent tuberculosis, typically years after initial infection.

Discussion:

• Clinical presentation includes back pain, fever, weight loss, and fatigue.
• Paraplegia can be an early sign of spinal involvement, though it is characteristically a late finding.
• A significant delay, averaging one year, often occurs between symptom onset and medical presentation.

Key Insights:

• Plain spinal radiographs are the primary diagnostic tool.
• Computed tomography (CT) and magnetic resonance imaging (MRI) aid in further defining the extent of the disease.
• Differential diagnosis must exclude neoplasm, pyogenic infections, fungal infections, and sarcoid arthritis.

Outlook:

• Continued vigilance for Pott's disease is necessary, particularly in older adults in developed countries.
• Early diagnosis and treatment are crucial to prevent severe complications like paraplegia.
• Advancements in imaging technologies improve diagnostic accuracy and management planning.
