Proximal junctional failure after surgical instrumentation in adult spinal deformity: biomechanical assessment of proximal instrumentation stiffness
Authors: Maeva Lopez Poncelas, Luigi La Barbera, Jeremy Rawlinson, Dennis Crandall & Carl-Eric Aubin
Study design: Assessment of different proximal instrumentation stiffness features to minimize the mechanical proximal junctional failure-related risks through computer-based biomechanical models.
Objective: To biomechanically assess variations of proximal instrumentation and loads acting on the spine and construct to minimize proximal junctional failure (PJF) risks.

Knee flexion compensation in postoperative adult spinal deformity patients: implications for sagittal balance and clinical outcomes
Authors: Sarthak Mohanty, Christopher Lai, Gabriella Greisberg, Fthimnir M. Hassan, Christopher Mikhail, Stephen Stephan, Joshua Bakhsheshian, Andrew Platt, Joseph M. Lombardi, Zeeshan M. Sardar, Ronald A. Lehman & Lawrence G. Lenke
Study Design: This single-center, single-surgeon retrospective study, assessed ASD patients who underwent posterior spinal fusion between 2014 and 2020.
Objective: To determine whether maintaining good sagittal balance with significant knee flexion (KF) constitutes a suboptimal outcome after adult spinal deformity (ASD) correction.
