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.

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.

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.

Biomechanical cadaver investigation. ⋯ Lumbar FSUs with implanted TDR were found to be less stiff, but absorbed more energy during cyclic loading with an unconstrained pendulum system. Although the effects on clinical performance of motion-preserving devices are not fully known, these results provide further insight into the biomechanical behavior of these devices under approximated physiological loading conditions.
