Case Reports
Histologic evaluation of human vertebral bodies after vertebral augmentation with polymethyl methacrylate.
Histologic documentation of vertebral bodies retrieved from human patients. ⋯ To our knowledge, these cases are among the first published reports of human histology after vertebral cement augmentation and have implications concerning the nature of the surgical procedures as well as the material used for injection.

A retrospective study investigated the sagittal alignment in adolescent idiopathic scoliosis (AIS). ⋯ Thoracic kyphosis depended mostly on the spinal deformity, whereas lumbar lordosis was influenced mainly by the pelvic configuration. The scoliotic curve type was not associated with a specific pattern of sagittal pelvic morphology and balance. The pelvic incidence found in this study was significantly higher than that reported in the literature for normal adolescents. The role of the pelvic incidence in the pathogenesis of adolescent idiopathic scoliosis needs to be explored in a longitudinal study involving patients with adolescent idiopathic scoliosis and normal adolescents.

Review Case Reports
Vertebral body ischemia in the posterior spinal artery syndrome: case report and review of the literature.
A case of posterior spinal cord syndrome in which magnetic resonance images showed predominant T2 hyperintense signal in the adjacent vertebral body is reported. ⋯ Associated bone marrow abnormalities likely reflect the underlying pathology of the blood supply to the vertebral body, and may be an additional key sign for radiologic diagnosis of posterior spinal cord syndrome.

An anatomic study investigated the cervical dorsal rami and major cervical paravertebral muscles. ⋯ With the posterior approach to the cervical spine, a precise knowledge of the cervical dorsal rami anatomy and the innervating patterns of the paravertebral muscles is necessary for avoidance of inadvertent injuries to the nerves.
