Suture Choice in Lumbar Dural Closure Contributes to Variation in Leak Pressures: Experimental Model.
Open-label laboratory investigational study; non-animal surgical simulation. ⋯ Durotomy closure in the lumbar spine with Gore-Tex suture may be a reasonable option for providing a watertight closure. In this laboratory study, Gore-Tex suture provided watertight dural closures that withstood higher peak pressures.

Anatomy of Lamina in the Subaxial Cervical Spine With the Special Reference to Translaminar Screws: CT and Cadaveric Analysis With Screw Trajectory Simulation.
A cadaveric study. ⋯ This is a report of the anatomy of the lamina in the subaxial cervical spine with the special reference to translaminar screws. It was analyzed with CT and cadaveric spines along with simulated screw trajectories. For the 1-degree translaminar screw, the entry point is the distance of the diameter of desired screw superior to the inferior margin of lamina-spinous process junction. The trajectory should be targeted toward the most superomedial corner of lateral mass. For the 2-degree translaminar screw, the entry point is the distance of the diameter of desired screw below the superior margin of lamina-spinous process junction, and the target is the most superolateral corner of lateral mass, which is typically horizontal. Further studies are needed to assess the feasibility of translaminar screw insertion in the actual subaxial cervical spine.

The Evolution of Current Research Impact Metrics: From Bibliometrics to Altmetrics?
The prestige of publication has been based on traditional citation metrics, most commonly journal impact factor. However, the Internet has radically changed the speed, flow, and sharing of medical information. Furthermore, the explosion of social media, along with development of popular professional and scientific websites and blogs, has led to the need for alternative metrics, known as altmetrics, to quantify the wider impact of research. ⋯ We suggest that altmetrics used in research evaluation should be part of an informed peer-review process such as traditional metrics. Moreover, results based on altmetrics must not lead to direct decision making about research, but instead, should be used to assist experts in making decisions. Finally, traditional and alternative metrics should complement, not replace, each other in the peer-review process.

Integrated Multidimensional Maturity Assessments Predicting the High-risk Occurrence of Peak Angle Velocity During Puberty in Progressive Female Idiopathic Scoliosis.
A consecutive and prospective longitudinal study. ⋯ Integrated multidimensional maturity assessments, defined as chronologic age between 11 and 13 years, modified Risser 0, DSA scores between 400 and 500, HV>6 cm/y, and SLV>20 mm/y, combined with preexisting scoliotic curve >30 degrees, were prone to increase the risk of entering the rapid curve acceleration phase in progressive IS girls.

Biomechanical Effects of a Dynamic Topping off Instrumentation in a Long Rigid Pedicle Screw Construct.
Biomechanical ex vivo study. ⋯ Introducing the dynamic topping off did not impart any significant difference in the segmental motion when compared with the rigid instrumentation. Therefore, the current biomechanical study could not show a benefit of using this specific topping off instrumentation to solve the problem of adjacent segment disease.
