BACKGROUND Involvement of both columns in acetabular fractures is a common presentation; these fractures create a challenging situation for the surgeons in terms of understanding the dimensions of osseous injury and selection of surgical approach. The study was done with an objective to evaluate the efficacy of single posterior approach for acetabular fractures involving both columns directly r...

  Background : Our aim in this study was to recognize the endoscopic anatomy of the Pterygopalatine fossa (PPF) and the anatomic variations of the related neurovascular structures, to define the endoscopic endonasal approach to this region.   Methods: In a case series study 17 fresh adult cadavers were studied by endoscopic endonasal approach. To reach the pterygopalatine fossa endonasally, we ...

Learning latent variable models with stochastic variational inference is challenging when the approximate posterior is far from the true posterior, due to high variance in the gradient estimates. We propose a novel rejection sampling step that discards samples from the variational posterior which are assigned low likelihoods by the model. Our approach provides an arbitrarily accurate approximat...

AIM This study reports a technique for treating severe thoracolumbar fractures with single-stage decompression, reduction, reconstruction, and stabilization via an entirely posterior approach. MATERIAL AND METHODS The cases of 11 patients with severe traumatic thoracolumbar fractures/dislocations that were managed with single-stage decompression, reduction, reconstruction, and stabilization v...
