Preliminary Shape Similarity Analysis and Standardization for Pre-Bent Rod Design for Adult Spinal Deformity Correction

Risk factors for rod fracture after posterior correction of adult spinal deformity with osteotomy: a retrospective case-series

BACKGROUND Osteotomies including pedicle subtraction (PSO) and/or Smith-Peterson (SPO) are used to facilitate surgical correction of adult spinal deformity (ASD), but are associated with complications including instrumentation failure and rod fracture (RF). The purpose of this study was to determine incidence and risk factors for RF, including a clinically significant subset (CSRF), after osteo...

Assessment of symptomatic rod fracture after posterior instrumented fusion for adult spinal deformity.

BACKGROUND Improved understanding of rod fracture (RF) in adult spinal deformity could be valuable for implant design, surgical planning, and patient counseling. OBJECTIVE To evaluate symptomatic RF after posterior instrumented fusion for adult spinal deformity. METHODS A multicenter, retrospective review of RF in adult spinal deformity was performed. Inclusion criteria were spinal deformit...

Predictive Model for Cervical Alignment and Malalignment Following Surgical Correction of Adult Spinal Deformity.

STUDY DESIGN Retrospective review of prospective multicenter database. OBJECTIVE Use predictive modeling to identify patient characteristics, radiographic, and surgical variables that predict reaching an outcome threshold of suboptimal cervical alignment after adult spinal deformity (ASD) surgery. SUMMARY OF BACKGROUND DATA Cervical deformity (CD) after ASD correction has been defined with ...

Revisiting the Curtis Procedure for Boutonniere Deformity Correction

Radiographic Outcomes of Adult Spinal Deformity Correction: A Critical Analysis of Variability and Failures Across Deformity Patterns.

STUDY DESIGN Multicenter, prospective, consecutive, surgical case series from the International Spine Study Group. OBJECTIVES To evaluate the effectiveness of surgical treatment in restoring spinopelvic (SP) alignment. SUMMARY OF BACKGROUND DATA Pain and disability in the setting of adult spinal deformity have been correlated with global coronal alignment (GCA), sagittal vertical axis (SVA)...
