Abstract
Objective. To investigate anatomical anthropometric parameters of the spine valid for transpedicular fixation (TPF) in patients with active tuberculous spondylitis and its late sequelae.
Material and Methods. The vertebral parameters from T1 to S1 important for TPF (screw paths length, pedicle widths and lengths, and pedicle angle) were determined using computer tomography in 18 patients from the control group, 18 patients with active tuberculous spondylitis, and 15 patients with post-tuberculous kyphosis resulted from the active process during the childhood.
Results. In patients with spondylitis consequences, the screw path length and the pedicle lengths decreased, and the pedicle widths and the pedicle angle increased at the apex of kyphosis. Opposite changes were observed in the areas adjacent to gibbus. No significant differences in the studied parameters were found in patients with active tuberculous spondylitis as compared to the norm.
Conclusion. In adult patients with sequelae of early age tuberculous spondylitis complicated by kyphotic deformity, screw sizes and their insertion angles should be chosen with consideration for changes in anatomical parameters of the vertebrae. Transpedicular fixation in thoracic and lumbar spine of patients with active spinal tuberculosis can be performed using standard instrumentation.
