Spine
-
Retrospective analysis of 260 patients with acute spine fractures treated at a tertiary trauma center from 1989 to 2009. ⋯ IPD measured from plain radiographs proved to be a reliable instrument to assess narrowing of the spinal canal, neurological deficits, and laminar fractures.
-
A computed tomography (CT) study. ⋯ Different anatomic patterns of PT curves could cause different altered positions of esophagus relative to spine and result in different potential risks of esophageal injuries during TPS insertion. Spine surgeons should choose appropriate pedicle screw length to avoid anterior cortical perforation in the PT region of AIS patients.
-
Molecular biological and immunohistological examinations. ⋯ These results suggest PGE2 and IL-6 play a pivotal role in the interaction between degenerated discs and macrophages.

Review Case Reports Multicenter Study
Changes in thoracic kyphosis negatively impact sagittal alignment after lumbar pedicle subtraction osteotomy: a comprehensive radiographic analysis.
Consecutive, multicenter retrospective review. ⋯ Significant postoperative alignment changes can occur through unfused thoracic spinal segments after lumbar PSO. Unfavorable RC may limit optimal correction and lead to clinical failures. Risk factors for unfavorable thoracic RC include older patients, larger preoperative PI and PT, and worse preoperative T1SPI and are not simply due to junctional failure. Care should be taken with selective lumbar fusion and PSO in older patients and in those with severe preoperative spinopelvic parameters.

Review Case Reports
Atypical extensive extratemporal hyperpneumatization of the skull base including the cervical spine: case report and review of the literature.
Case report and clinical discussion. ⋯ Atypical radiolucency may represent a very rare benign hyperpneumatization of the skull base, which may include the craniocervical junction. Because of microfractures of the thinned and consecutive, less stable bones, this also can lead to free air and soft-tissue emphysema, which has not been described previously. Special care should be taken to identify epidural free air because of a possible communication of the epidural space with the external environment. Harmful activities and especially high-speed trauma could result in fractures of the cervical spine due to decreased stability of the hyperpneumatized bones.
