Background and objectives: To evaluate success rate, acceptance and complications of sciatic nerve (SN) block at the popliteal fossa (popliteal block, PB) for ambulatory or inpatient orthopedic and vascular surgical procedures. Methods: A retrospective study was carried out in 312 patients who received a PB for vascular and orthopedic lower leg surgery. A single injection, posterior approach te...

Background & Importance: Spinal deformity is one of the most common disorders among the vertebral diseases that results from unnatural curvatures of spine, such as scoliosis and kyphosis. Spinal fusion surgery is used most commonly to treat certain types of spinal deformity. Herein, we reported the efficacy of posterior spinal fusion accompanied by instrumentation in patients with the...

INTRODUCTION We describe a surgical technique for ptosis correction in moderate to good levator function involving advancement of the levator aponeurosis via a transconjunctival posterior approach without resection of Müller's muscle. We present our experience of and the results from this method, and review the evolution of posterior approach ptosis surgery. PURPOSE To assess the efficacy and...

STUDY DESIGN This is descriptive analytical study. PURPOSE The present study aims at comparing treatment results found between the two groups comprising of patients who underwent posterior spinal fusion using thoracic pedicle screws and the ones who underwent combined anterior-posterior method, respectively. OVERVIEW OF LITERATURE There was controversy about surgical techniques including an...

[1] When a single model is used for hydrologic prediction, it must be capable of estimating system behavior accurately at all times. Multiple-model approaches integrate several model behaviors and, when effective, they can provide better estimates than that of any single model alone. This paper discusses a sequential model fusion strategy that uses the Bayes rule. This approach calculates each ...

Many statistical models can be simulated forwards but have intractable likelihoods. Approximate Bayesian Computation (ABC) methods are used to infer properties of these models from data. Traditionally these methods approximate the posterior over parameters by conditioning on data being inside an -ball around the observed data, which is only correct in the limit →0. Monte Carlo methods can then ...

STUDY DESIGN Retrospective case series. PURPOSE To describe a novel single incision that combines anterior and posterior approaches for decompression and instrumented fusion to treat tuberculosis of the thoracic spine and study the neurological and radiological outcomes. OVERVIEW OF LITERATURE Tuberculosis of the spine remains a major health issue in many developing countries. The options f...

The accuracy of cup position in total hip arthroplasty is essential for a satisfactory result as malpositioning increases the risk of complications including dislocation, high wear rate, loosening, squeaking, edge loading, impingement and ultimately failure. We studied 166 patients in a single-surgeon-series of matched cohorts of patients who underwent total hip arthroplasties. Four separate gr...

Background: Ganglioneuroma is a rare benign tumor, which is usually located in the posterior mediastinum and retroperitoneum. Occasionally, it involves the paraspinal region with intraspinal extension and becomes dumbbell shaped. Dumbbell ganglioneuromas rarely affect the lumbar spine, and only nine cases of dumbbell lumbar ganglioneuromas have been reported previously. Case presentation: We ar...
