Second sacral sacralalar‐iliac (S2AI) screw placement in adult degenerative scoliosis (ADS) patients: an imaging study

Abstract Background The imaging characteristics of sacral sacralalar-iliac (S2AI) screw trajectory in adult degenerative scoliosis (ADS) patients will be determined.Methods S2AI screw trajectories were mapped on three-dimensional computed tomography (3DCT) reconstructions of 40 ADS patients.The starting point, placement plane, screw template, and a

Rapid defect prediction and optimisation method for Ti-modified AlCuMg alloys processed by laser powder-bed fusion

Ti-modified AlCuMg alloys have demonstrated great potential in improving the printability and mechanical properties of conventional Al alloys processed by laser powder-bed fusion (LPBF).However, an effective material design method, which considers processing parameters and solidification microstructure, is currently absent.Accordingly, the present

The Balanced Opioid Initiative: protocol for a clustered, sequential, multiple-assignment randomized trial to construct an adaptive implementation strategy to improve guideline-concordant opioid prescribing in primary care

Abstract Background Rates of opioid prescribing tripled in the USA between 1999 and 2015 and were associated with significant increases in Puzzle opioid misuse and overdose death.Roughly half of all opioids are prescribed in primary care.Although clinical guidelines describe recommended opioid prescribing practices, implementing these guidelines in
