Mycobacterial Musculoskeletal Infections

Area of Science:

• Infectious Diseases
• Orthopedics
• Microbiology

Background:

• Mycobacterial infections, including Mycobacterium tuberculosis and nontuberculous mycobacteria, are increasingly recognized causes of musculoskeletal infections.
• While tuberculous arthritis and osteomyelitis are ancient diseases, nontuberculous mycobacterial infections are more frequently identified due to host factors and diagnostic advancements.
• Despite medical progress, diagnosing and managing mycobacterial bone and joint infections remain complex.

Purpose of the Study:

• To review the clinical manifestations, pathogenesis, risk factors, and diagnostic and therapeutic strategies for musculoskeletal infections caused by Mycobacterium tuberculosis and nontuberculous mycobacteria.

Main Methods:

• Literature review focusing on clinical presentations, epidemiological data, and treatment outcomes.
• Analysis of diagnostic modalities and challenges in identifying mycobacterial bone and joint infections.
• Synthesis of current understanding of pathogenesis and risk factors.

Main Results:

• Mycobacterial infections affect bones and joints, presenting unique clinical signs.
• Nontuberculous mycobacteria are increasingly implicated, necessitating improved diagnostic approaches.
• Effective management requires a comprehensive understanding of pathogenesis and tailored therapeutic strategies.

Conclusions:

• Mycobacterial musculoskeletal infections, though less common than pyogenic ones, pose significant diagnostic and therapeutic challenges.
• Increased identification of nontuberculous mycobacterial infections highlights the need for enhanced diagnostic capabilities and awareness.
• A multidisciplinary approach is essential for optimal patient outcomes in managing these infections.
