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 کاملPerioperative Complications of Pedicle Subtraction Osteotomy
Study Design Retrospective case series. Objective To describe the perioperative complications (0 to 90 days) associated with pedicle subtraction osteotomies (PSOs) performed at a tertiary spine center by two experienced spine surgeons who recently adopted the technique. Methods We reviewed all 65 patients (47 women and 18 men; mean age 60 years, range 24 to 80) who underwent a PSO at our instit...
متن کاملBiomechanical analysis of revision strategies for rod fracture in pedicle subtraction osteotomy.
BACKGROUND Pseudoarthrosis after pedicle subtraction osteotomy (PSO) can require revision surgery due to posterior rod failure, and the stiffness of these revision constructs has not been quantified. OBJECTIVE To compare the multidirectional bending stiffness of 7 revision strategies following rod failure. METHODS Seven fresh-frozen human spines (T11-pelvis) were tested as follows: (1) post...
