Thoracic hyperkyphosis is a sagittal deformity that can cause back pain and neurological impairment, leading to difficulties in maintaining a straight gaze. Sagittal thoracic malalignment has different etiologies and different corrective strategies. An adequate preoperative planning is mandatory to address correctly the surgical treatment, using an appropriate sagittal deformities classification and the rules that relate pelvic parameters to spine curvatures to determine the correction needed to restore a good sagittal alignment. Ponte osteotomies are performed in long non-angular hyperkyphotic thoracic deformities, even if idiopathic scoliosis, rigid deformities or proximal junctional kyphosis after instrumented fusions can benefit from the application of this technique that requires a mobile anterior column for the correction of the deformity. Ponte’s is, together with Smith-Petersen osteotomy, a posterior column osteotomy. The magnitude of correction can reach 10° per level if intervertebral discs are still mobile.
