Biomechanical Comparison of the Load-Sharing Capacity of High and Low Implant Density Constructs With Three Types of Pedicle Screws for the Instrumentation of Adolescent Idiopathic Scoliosis – NA (2019) Julien Clin

Description

Biomechanical numerical simulation study comparing high and low implant density pedicle screw constructs (uniaxial, multiaxial, favored angle) for posterior instrumentation of Adolescent Idiopathic Scoliosis (AIS), evaluating deformity correction and construct load-sharing capacity during and after surgery. Findings indicated similar coronal correction but reduced postoperative implant loads with high-density constructs.
