Minimally invasive posterolateral hip approach with SPARTAQUUS (Spare the Piriformis And Respect The Active QUadratus femoris and gluteus mediUS) technique.

Interest in the different surgical approaches to total hip arthroplasty remains high, but without any real consensus on which approach is the most beneficial. Several recent technical innovations have made it possible to reduce the risk of dislocation, therefore improving the efficacy of the posterolateral approach. Since 2003, we have been using a modified minimally invasive posterolateral approach called SPARTAQUUS (Spare the Piriformis And Respect The Active QUadratus femoris and gluteus mediUS), which spares the piriformis tendon, the quadratus femoris muscle and the gluteus medius muscle, and involves direct capsular repair.

Thoracic Stent-Graft Migration: The Role of the Geometric Modifications of the Stent-Graft at 3 years.

Background: To date, clinical and experimental studies on stent graft (SG) migration have focused on aortic morphology and blood flow. However, thoracic endovascular aortic repair (TEVAR) is not an instant fixation of the SG in the aortic lumen but rather a continuous process of deformation and three-dimensional change in the configuration and the geometry of the SG. The aim of this study was to analyze the geometric evolution of the aortic SG in the proximal attachment zone at midterm follow-up and its impact on the SG migration.

Three-dimensional reconstruction of the temporal bone: Comparison of in situ, CT, and CBCT measurements.

Objective: To evaluate the accuracy of three-dimensional (3D) Cone Beam Computed Tomography (CBCT) and Computed Tomography (CT) reconstructions of human temporal bones compared with in situ measurements.

Material And Methods: Experimental anatomical study of 10 human temporal bones. Wilcoxon's test was used to compare 8 distances on each temporal bone measured in situ and then on 3D CT and CBCT reconstructions.

Characterization of the Physiological Displacement of the Aortic Arch Using Non-Rigid Registration and MR Imaging.

Objectives: The aim of this work was to study physiological aortic arch three-dimensional displacement using non-rigid registration methods and magnetic resonance imaging (MRI).

Materials And Methods: Ten healthy volunteers underwent thoracic MRI. Prospective cardiac gating was performed with a 3D turbo field echo sequence to obtain end-systolic and end-diastolic MR images.

[Peribulbar anesthesia: efficacy of a single injection with a limited local anesthetic volume].

Introduction: Cataract surgery can be performed with peribulbar anesthesia. The classical technique consists of two injections of local anesthetics. The purpose of our study was to assess peribulbar anesthesia with a single injection and a limited volume of local anesthetics.
