STUDY DESIGN Multicenter, retrospective, consecutive case series. OBJECTIVE This study aims to identify demographic and radiographical characteristics that influence the decision to perform revision surgery among patients with proximal junctional failure (PJF). SUMMARY OF BACKGROUND DATA Revision rates after PJF remain relatively high, yet the decision criteria for performing revision surgi...
Pedicle screw instrumentation constructs have become a cornerstone in the treatment of adult spinal deformity and instability. They are known to provide greater rigidity and enhanced ability to correct and maintain spinal alignment. Biomechanical data, however, demonstrate that increased construct stiffness is associated with increased loading within adjacent segments [1– 9]. Increasingly stiff...
STUDY DESIGN A retrospective study. OBJECTIVE To analyze the long-term proximal junctional change in adolescent idiopathic scoliosis (AIS) following segmental posterior spinal instrumentation and fusion 5 years or more after surgery. SUMMARY OF BACKGROUND DATA No study has concentrated on time-dependent long-term proximal junctional change in AIS following segmental posterior spinal instrum...
The aim of this study was to estimate the prevalence and patient outcomes of proximal junctional kyphosis (PJK) in pediatric patients and adolescents who received surgical interventions for the treatment of a spinal deformity.Literature was searched in electronic databases, and studies were selected by following précised eligibility criteria. Percent prevalence values of the PJK in individual s...
BACKGROUND Thoracolumbar junction (TLJ) is the transitional area between the lower thoracic spine and the upper lumbar spine. Vertebral compression fractures and proximal junctional kyphosis following spine surgery often occur in this area. Therefore, the study of development and mechanisms of thoracolumbar junctional degeneration is important for planning surgical management. This study aimed ...
BACKGROUND Radiological outcomes between anterior and posterior approach in Lenke 5C curves were still controversial. Meta-analysis on published articles to compare fusion segments and radiological outcomes between the two surgical approaches was performed. METHODS Electronic database was conducted for searching studies concerning the anterior versus posterior approach in Lenke 5C curves. Aft...
