Review Case Reports
Intradural extramedullary hemangiopericytoma of the thoracic spine infiltrating a nerve root: a case report and literature review.
Review the presentation and diagnosis of an intradural extramedullary hemangiopericytoma of the thoracic spine. ⋯ This is the ninth report of spinal intradural hemangiopericytoma. The location of the neoplasm supports the hypothesis that hemangiopericytoma may arise from the spinal pial capillaries.

Comparative Study
Disc replacement adjacent to cervical fusion: a biomechanical comparison of hybrid construct versus two-level fusion.
A cadaveric biomechanical study. ⋯ The porous-coated motion cervical prosthesis restored the ROM of the treated level to the intact state. When the porous-coated motion prosthesis was used in a hybrid construct, the TDR response was not adversely affected. A hybrid construct seems to offer significant biomechanical advantages over two-level fusion in terms of reducing compensatory adjacent-level hypermobility and also loads required to achieve a predetermined ROM.

Randomized Controlled Trial Multicenter Study
Polyethylene glycol hydrogel spinal sealant (DuraSeal Spinal Sealant) as an adjunct to sutured dural repair in the spine: results of a prospective, multicenter, randomized controlled study.
A prospective, multicenter, randomized, two-arm, single-blind, investigational device exemption pivotal study. ⋯ The PEG hydrogel spinal sealant evaluated in this study is safe and effective for providing watertight closure when used as an adjunct to sutured dural repair during spinal surgery. This readily available tool is superior to other standard of care technologies commonly used to achieve intraoperative watertight dural closure.

A clinical prospective study. ⋯ The recovery rate of the JOA score in the ADF group was better than that in the LAMP group. The clinical outcomes after LAMP could be influenced by ACS.

A fully blocked experimental design using clinical vignettes to query primary care physicians on prescription for management of acute nonspecific low back pain. ⋯ All three assessed nonclinical factors influenced physician decisions regarding diagnostic and treatment recommendations for acute nonspecific low back pain. Patient presentation, suggestive of a patient's emotional state, was shown to be the most influential.
