Pedicle 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...
متن کاملPedicle Subtraction Osteotomy with a Cage Prevents Sagittal Translation in the Correction of Kyphosis in Ankylosing Spondylitis
BACKGROUND Sagittal translation (ST) is an accidental event that surgeons commonly encounter during a spinal osteotomy in the correction of kyphosis in ankylosing spondylitis (AS). However, there is a paucity of effective techniques to prevent ST. The purpose of this study was to propose a pedicle subtraction osteotomy (PSO) with a cage as a method to prevent ST and to explore the efficacy and ...
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 rigid post-tuberculous kyphosis.
We studied 15 patients with healed tuberculosis of the spine and a resultant kyphosis. We selected only those with no neurological deficit and performed a wedge resection of the vertebra using a transpedicular approach. The wedge was removed from the apex of the deformity. For those with a neurological deficit, we chose the conventional anterior debridement and decompression with 360 degrees ci...
متن کاملPosterior wedge osteotomy and debridement for Andersson lesion with severe kyphosis in ankylosing spondylitis
BACKGROUND Andersson lesion is a well-known complication in ankylosing spondylitis. Recently, owing to the worry about the healing of fracture, some scholars advocated additional anterior surgery or other procedures were necessary, which increase the risk of the nerve injury. The purpose of this study is to introduce our experience and to explore the efficacy and feasibility of posterior wedge ...
