Hydroxyapatite coating improves fixation of pedicle screws [PDF]

, 2002
We investigated the effects of hydroxyapatite (HA) coating on the purchase of pedicle screws. A total of 23 consecutive patients undergoing lumbar fusion was randomly assigned to one of three treatment groups. The first received uncoated stainless-steel

Assessment of Medial Malpositioning during Thoracic Pedicle Screws Placement with a Contemporary Intraoperative Neurophysiological Monitoring Method

Global Spine Journal, 2015
Introduction Thoracic pedicle screws placement remains being a challenge despite modern technologies available. To assess neural integrity during these surgeries, intraoperative neurophysiological monitoring (IOM) is indicated.

Combined Anterior Cruciate Ligament Reconstruction and Lateral Extra‐articular Tenodesis With Augmented Continuous Iliotibial Band Autograft

Arthroscopy Techniques, EarlyView.
Abstract The purpose of this technical note is to describe a reproducible surgical technique for anterior cruciate ligament reconstruction combined with a lateral tenodesis using a continuous iliotibial band autograft that allows self‐augmentation of graft diameter without the need for additional tendon harvesting.

The Impact of Aging on the Anatomical Course of the Azygos Vein: A Retrospective, Computed Tomography Study

Clinical Anatomy, EarlyView.
ABSTRACT The azygos vein (AV) is typically described as ascending vertically to the right of the vertebral column before arching anteriorly to drain into the superior vena cava. However, a small number of studies suggest that it is found leftward in older adults.

Early Postoperative Adverse Events (≤ 30 Days) in Spinal Oncology: Defining the Incidence, Severity, and Predictors in a Mixed Prospective Cohort Including Intradural and Metastatic Spinal Tumors

International Journal of Cancer, EarlyView.
ABSTRACT Complication reporting in spinal tumor surgery remains inconsistently defined. We aimed to quantify the incidence, severity, and spectrum of early (≤ 30 days) postoperative adverse events (AEs) in spinal tumor surgery and to identify predictors of overall and serious complications using standardized severity grading.

Finite element analysis of the pedicle screw in lumbar transpedicular dynamic stabilization that penetrates the lateral cortex of the vertebral pedicle

BMC Musculoskeletal Disorders
Background The mechanical stability of lumbar transpedicular dynamic stabilization (LTDS) was determined by simulating the degree to which the pedicle screws penetrated the lateral pedicle cortex.
