First Reported Case of Reverse Pott's Disease

Area of Science:

• Infectious Diseases
• Orthopedic Surgery
• Public Health

Background:

• Tuberculosis (TB) is a significant global health concern, primarily affecting the lungs but capable of extrapulmonary spread.
• Extrapulmonary TB can present in various forms, including vertebral osteomyelitis, commonly known as Pott's Disease.
• Allogenic bone grafts are utilized in orthopedic surgery to facilitate bone healing and structural support.

Observation:

• A patient developed Pott's Disease following back surgery involving an allogenic bone graft.
• Subsequent investigations revealed disseminated tuberculosis originating from the infected bone graft.
• This case underscores a rare but serious complication associated with allograft transplantation.

Findings:

• The infected bone graft served as the source of disseminated tuberculosis in the patient.
• Current screening protocols for allograft tissue may not adequately identify all risks of TB transmission.
• The case highlights a potential gap in infectious disease surveillance for tissue allografts.

Implications:

• There is a potential need to re-evaluate and potentially standardize tuberculosis screening for bone allografts.
• Enhanced vigilance and screening protocols could prevent rare but severe infectious complications post-transplantation.
• This case contributes to the understanding of TB transmission routes and informs future public health strategies for tissue banking and transplantation.
