Instrumentation failure following pedicle subtraction osteotomy: the role of rod material, diameter, and multi-rod constructs

, 2017
Purpose: Pedicle subtraction osteotomy (PSO) has a complication rate noticeably higher than other corrective surgical techniques used for the treatment of spinal sagittal imbalance. In particular, rod breakage and pseudoarthrosis remain burning issues of

L5 Partial Pedicle Subtraction Osteotomy in High Pelvic Incidence Patients: A New Way to Manage Lordosis

, 2022
Introduction: Numerous corrective osteotomy techniques have been reported in lumbar area. Owing to mechanical difficulties and reputation of higher neurological risk, L5 pedicle subtraction osteotomy (PSO) has been poorly used and described.

Kinematic efficacy of supplemental anterior lumbar interbody fusion at lumbosacral levels in thoracolumbosacral deformity correction with and without pedicle subtraction osteotomy at L3:an in vitro cadaveric study

, 2017
PURPOSE: Pedicle subtraction osteotomy (PSO) is performed to treat rigid, sagittal spinal deformities, but high rates of implant failure are reported. Anterior lumbar interbody fusion has been proposed to reduce this risk, but biomechanical investigation

Sandwich strategy for the treatment of kyphosis with scoliosis and bilateral hip ankylosis in ankylosing spondylitis: a case report

Frontiers in Surgery
Ankylosing spondylitis can present with severe kyphosis, scoliosis, and bilateral hip ankylosis, posing significant therapeutic challenges. Conventional “hip-first” or “spine-first” strategies are often limited by interdependent biomechanical constraints.
