A cadaveric survey of the thoracic spines of extant species of nonbipedal primates for the presence of Scheuermann kyphosis. ⋯ Thoracic kyphotic deformity consistent with Scheuermann kyphosis exists in quadrupedal nonhuman primates. Bipedalism is not a strict requirement for the development of Scheuermann kyphosis, and the evolutionary origins of the disease predate the vertebral adaptations of bipedal locomotion.

Multicenter Study
Cervical spine trauma in diffuse idiopathic skeletal hyperostosis: injury characteristics and outcome with surgical treatment.
Retrospective study of a consecutive series of operatively managed patients with cervical fractures with diffuse idiopathic skeletal hyperostosis (DISH) presenting to 3 institutions over an 8 year period. ⋯ The current findings pinpoint the potential for medical and surgical complications in this high risk subgroup. Surgeons should be aware of the unique aspects associated with treatment of these injuries.

Comparative Study
Comparison of 3 reconstructive techniques in the surgical management of multilevel cervical spondylotic myelopathy.
A retrospective comparative study was performed in patients with 3-level cervical spondylotic myelopathy (CSM). ⋯ The HDF can be considered an effective and safe alternative procedure compared with ACDF in the treatment of the multilevel CSM, and ACCF should be the last option.

Prospective study in a morbidly obese population after bariatric surgery. ⋯ Bariatric surgery, resulting in significant weight reduction, was associated with a significant decrease in low back and radicular pain as well as a marked increase in the L4-L5 intervertebral disc height. Reduction in body weight after bariatric surgery in morbidly obese patients is associated with a significant radiographical increase in the L4-L5 disc space height as well as a significant clinical improvement in axial back and radicular leg pain.

A retrospective review of a prospectively collected database. ⋯ This study provides rates and causes of mortality associated with spine surgery for a broad range of diagnoses and includes assessments for adult and pediatric patients. These findings may prove valuable for patient counseling and efforts to improve the safety of patient care.
