Bone and Joint Infections

Bone and joint infections, also known as musculoskeletal infections, encompass a diverse group of conditions involving bacterial or fungal invasion of bones, joints, and surrounding tissues. These infections can result from hematogenous spread, direct extension from adjacent tissues, or traumatic inoculation. Staphylococcus aureus is a common culprit, particularly in acute hematogenous osteomyelitis, while prosthetic joint infections may involve a broader range of pathogens. Clinical manifestations include localized pain, swelling, redness, and limited joint mobility. In severe cases, systemic symptoms such as fever and chills may also be present. Diagnosis often relies on imaging studies, blood cultures, and sometimes joint aspirations to identify the causative organism. Treatment of bone and joint infections involves a combination of surgical intervention and antimicrobial therapy. Debridement, drainage, and, in some cases, joint replacement may be necessary to eliminate the source of infection. The choice of antibiotics is guided by the identified pathogen and its susceptibility profile. Duration of therapy varies but is generally prolonged, requiring close monitoring for resolution and potential complications. The emergence of antibiotic-resistant strains, especially methicillin-resistant Staphylococcus aureus (MRSA), emphasizes the importance of judicious antibiotic use and adherence to infection control measures.
