A Novel Technique for Spondylolysis Repair With Pedicle Screws, Rod and Polyester Band: Case Report With Technical Note and Systematic Literature Review.

Study Design: Systematic review and case report.

Objective: Our study aims to present a new technique using three components to repair the pars defect: pedicle screws, rod and polyester band. Furthermore, we perform a systematic literature review of the previously described techniques.

Surgical treatment of spinal disorders in Parkinson's disease.

Purpose: Most patients suffering from Parkinson's disease (PD) exhibit alterations in the posture, which can in several cases give rise to spine deformities, both in the sagittal and the coronal plane. In addition, degenerative disorders of the spine frequently associated to PD, such as spinal stenosis and sagittal instability, can further impact the quality of life of the patient. In recent years, spine surgery has been increasingly performed, with mixed results.

[Regional differences in viscosity, elasticity and wall buffering function in systemic arteries: pulse wave analysis of the arterial pressure-diameter relationship].

Introduction And Objectives: Regional variations in the incidence of vascular diseases have been related to regional differences in arterial viscoelasticity. The aim of this study was to characterize the differences in the elastic and viscous modulus and in wall buffering function between central and peripheral systemic arteries, through a time-series analysis of the pressure-diameter relationship.

Material And Method: Pressure and diameter were measured in seven arterial segments (carotid, brachiocephalic trunk, ascending aorta, proximal, middle and distal descending thoracic aorta, and femoral artery) from six sheep.
