OBJECTIVE Proximal junctional kyphosis (PJK) remains problematic following multilevel
instrumented spine surgery. Previous biomechanical studies indicate that providing less …

OBJECTIVE Proximal junctional kyphosis (PJK) is, in part, due to altered segmental
biomechanics at the junction of rigid instrumented spine and relatively hypermobile non …

Study Design. Biomechanical analysis of proximal junctional kyphosis (PJK) through
computer simulations and sensitivity analysis. Objective. To gain biomechanical knowledge …

OBJECTIVE Proximal junctional kyphosis (PJK) and failure (PJF) are potentially catastrophic
complications that result from abrupt changes in stress across rigid instrumented and mobile …

OBJECTIVE To determine if junctional tethers reduce PJK after multilevel instrumented
surgery for adult spinal deformity (ASD). METHODS ASD patients who underwent posterior …

Background context Correction of adult spinal deformity (ASD) by long segment
instrumented spinal fusion is an increasingly common surgical intervention. However, it is …

Study Design. Biomechanical study in a porcine model. Objective. To determine whether
transverse process hooks (TPHs) placed at the proximal end of a long posterior spinal fusion …

OBJECTIVE Proximal junctional kyphosis (PJK) is a well-recognized, yet incompletely
defined, complication of adult spinal deformity surgery. There is no standardized definition …

Abstract Background Context Little is known about the effect of rod stiffness as a risk factor of
proximal junctional kyphosis (PJK) after adult spinal deformity (ASD) surgery. Purpose The …

BACKGROUND: Proximal junctional kyphosis (PJK) is a well-recognized complication in
patients undergoing posterior instrumented fusion procedures for adult spinal deformity …
