Surgical approaches to upper thoracic Pott's disease with spinal instability during childhood: two cases.

Abstract

Tuberculosis is a common disease worldwide that is caused by Mycobacterium tuberculosis. Tuberculosis is primarily a pulmonary disease, but extrapulmonary manifestations are not uncommon, especially in children and adolescents. We present two pediatric patients who underwent surgery in our clinic for Pott's disease in the upper thoracic region. The patients were investigated to describe their age, complaints, neurological examination results, disease location, surgical procedure, and complications. The patients were 2 and 14years old and exhibited disease located in the upper thoracic region (T2-T3 and T1-T2). Both patients displayed severe neurological deficits (Frankel B and C). The kyphotic angles were 82.2° and 43.2°. The patients were stabilized by applying fusion using transpedicular screws via a posterior approach. They also underwent anti-tuberculosis treatment for approximately 1year. One year later, neither patient exhibited any neurological deficit, and their kyphotic angles were measured as 11° and 1°, respectively. The recommended treatment approach for unstable cases of Pott's disease located in the upper thoracic region who exhibit neurological deficit and severe kyphotic angling or the development of kyphosis on the thoracic vertebrae is surgical. Decompression, stabilization, and fusion and kyphotic correction can be safely performed via a posterior approach. One of the present cases is the youngest patient described in the literature to undergo transpedicular surgery as a result of Pott's disease. Our other case is the first described in the literature who developed ptosis as a result of tuberculosis and underwent a procedure via posterior transpedicular screw.
