Does vertebral level of pedicle subtraction osteotomy correlate with degree of spinopelvic parameter correction?
OBJECT Pedicle subtraction osteotomy (PSO) is a spinal realignment technique that may be used to correct sagittal spinal imbalance. Theoretically, the level and degree of resection via a PSO should impact the degree of sagittal plane correction in the setting of deformity. However, the quantitative effect of PSO level and focal angular change on postoperative spinopelvic parameters has not been...

متن کاملConstruct Rigidity after Fatigue Loading in Pedicle Subtraction Osteotomy with or without Adjacent Interbody Structural Cages
Introduction Studies document rod fracture in pedicle subtraction osteotomy (PSO) settings where disk spaces were preserved above or adjacent to the PSO. This study compares the multidirectional bending rigidity and fatigue life of PSO segments with or without interbody support. Methods Twelve specimens received bilateral T12-S1 posterior fixation and L3 PSO. Six received extreme lateral interb...
متن کاملPedicle Subtraction Osteotomy in a 5-Year-Old Child with Congenital Kyphosis
Vertebral anomalies may also distort the normal regional or global spinal alignment and necessitate some therapeutic interventions. Hemiepiphysiodesis is a traditional procedure usually described for these young patients but in more severe cases some type of osteotomy seems to be necessary. In this technical note, we describe a 5-year-old boy with failed previous hemiepiphysiodesis surgery, who...
متن کاملPedicle subtraction osteotomy for correction of severe thoracolumbar kyphosis in ankylosing spondylitis.
Introduction Ankylosing spondylitis (AS), a chronic inflammatory arthritis, primarily involves the axial skeleton and results in severe thoracolumbar kyphotic deformity. Treating AS-related kyphotic deformity typically involves one or more posterior wedge osteotomies and manipulation of the position of the spine by forceful manual extension to close them. Several types of osteotomy are availabl...
