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.

Randomized Controlled Trial
A randomized, controlled, double-blind trial of fluoroscopic caudal epidural injections in the treatment of lumbar disc herniation and radiculitis.
A randomized, controlled, double-blind trial. ⋯ Caudal epidural injection with local anesthetic with or without steroids might be effective in patients with disc herniation or radiculitis. The present evidence illustrates potential superiority of steroids compared with local anesthetic at 1-year follow-up.

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.

A retrospective case study. ⋯ Angulated odontoid fractures with the OPTA around 30° at the time of bony union in infants younger than 3 years of age could have the capacity for remodeling to the normal morphology. No surgical reduction might be needed to recommend complete apposition of the odontoid process in the absence of severe or deteriorating neural impairment.
