In tuberculous spondylodiscitis, very progressed cases may demonstrate an extensive loss of vertebral body height with severe kyphotic angulation, known as a gibbus deformity.
In chronic cases, expected vertebral body changes include bony fragmentation, anterior vertebral osteolysis with wedging, and in very advanced cases an extensive loss of vertebral body height with severe kyphotic angulation, known as the gibbus deformity (Figure 9).
Prediction of the angle of gibbus deformity
in tuberculosis of the spine.
Patient had exaggerated lordosis along with Gibbus deformity
in lumbar region.
Thus, when the anterior and middle columns in vertebrae and discs are destroyed by TB, physiological loading results in a progressive kyphus deformity producing the characteristic external gibbus deformity
(13) and paraplegia of late onset due to the internal gibbus (14, 15).
Some conditions of the thoracic spine are severe, such as the gibbus deformity
(hunchback), in which excessive kyphosis causes sharp angulation of the spine.
At 1 year of her age, the parents noticed a lumbar gibbus deformity
and later, their concerns increased as she did not walk independently at 16 months of age.
