Learning targets • To learn details on the minimally invasive surgical lateral approach to the upper lumbar spine, • To identify a surgical strategy for anterior correction of rigid posttraumatic kyphosis, • To describe a method for anterior column reconstruction with reduced bleeding, • To identify a strategy to reduce the risk of bone subsidence.
INTRODUCTION Degenerative scoliosis is a three-dimensional deformity that can present in some instances with fixed sagittal and coronal imbalance. Pedicle subtraction osteotomy (PSO) is an effective technique that allows correction with a posterior approach. When a combined coronal and sagittal imbalance is present, asymmetric PSOs could be an optimal… (More)
Since the introduction of Cotrel-Dubousset instrumentation in 1984, the correction techniques in scoliosis surgery have changed from Harrington principles of concave distraction to segmental realignment to a variety of possibilities including the rod rotation manoeuvres, and to segmental approximation via cantilever methods. Additionally, pedicle screw… (More)
BACKGROUND Proximal junctional kyphosis (PJK) is a frequent complication that compromises the outcomes of spinal surgery, especially for adult deformity. To the date no single risk factor or cause has been identified that explains its occurrence. The purpose of this study was to investigate the test-retest reliability of the radiologic measurements using… (More)
INTRODUCTION Sagittal imbalance is a spine deformity with multifactorial etiology, associated with severe low back pain and gait disturbance that worsen deeply patients' quality of life. The amount of correction achievable through PSO is limited by the height of the resection of the posterior wall, causing a ceiling of segmental correction of 30-35°. The… (More)
