Posterior column shortening for Scheuermann kyphosis. A, Broad posterior resection (shaded parts) at every intersegmental level of entire area of fusion and instrumentation. B, Posterior view showing levels of completed resections. C, Lateral view showing gaps from osteotomies. Correction is achieved by closing gaps. D, Oblique view showing three apical vertebrae after completion of bone resections. Apical vertebra is left uninstrumented. E-H, Schematic representation of reduction of kyphosis. SEE TECHNIQUE 44.44.
