A prospective study of the sagittal standing posture of 766 adolescents. ⋯ Meaningful classifications exist for adolescent sagittal thoraco-lumbo-pelvic alignment, and these can be determined successfully from sagittal photographs. More neutral thoraco-lumbo-pelvic postures are associated with less back pain.

Case series. ⋯ Relapse of low back or buttock pain and leg pain after thoracolumbar fusion to the sacrum may be related to a sacral fracture, difficult to diagnose in conventional radiographs. Surgery should be considered in the presence of a concomitant L5-S1 pseudarthrosis and when symptoms do not improve with the nonoperative treatment.

Case Reports
Traumatic complex dislocation of the atlanto-axial joint with odontoid and C2 superior articular facet fracture.
Case report and clinical discussion. ⋯ To our knowledge, this is the first case of a traumatic atlantoaxial rotatory dislocation with accompanying odontoid and C2 superior articular facet fracture.

A retrospective clinical study with a follow-up of more than 7 years was conducted. ⋯ In the long-term, instrumented PLIF with a single closed-box titanium cage shows similar radiologic results compared to fusion with 2 titanium cages. Implantation of a single titanium closed-box cage in an instrumented PLIF seems to be adequate in case of degenerative lumbar spinal disease.
