Pedicle-sparing transforaminal thoracic spine wedge osteotomy for kyphosis correction
نویسندگان
چکیده
BACKGROUND Correction of a focal kyphotic deformity at times requires performing a pedicle subtraction osteotomy, which is accompanied by loss of pedicles as anchor points at the affected level in addition to significant blood loss. To help alleviate these two issues, a novel osteotomy technique for correction of kyphosis using a transforaminal approach to the thoracic vertebral body is described. METHODS We describe a bilateral pedicle-sparing approach and demonstrate it in a patient with proximal junctional kyphosis. RESULTS The proposed osteotomy resulted in a 28-degree Cobb angle improvement in the sagittal plane. CONCLUSION The operation resulted in a similar degree of correction as a pedicle subtraction osteotomy, with the added benefit of maintaining the pedicles closest to the kyphotic deformity.

BACKGROUND Sagittal rebalancing of a fixated lumbar hypolordosis (kyphosis) is very important to gain satisfactory results. To correct a misalignment vertebral column resection or pedicle subtraction osteotomies are favored, disregarding the relatively high complication rates. The aim of this study was to evaluate the efficiency and safety of a new modified transforaminal lumbar fusion techniqu...
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...

BACKGROUND Fixed sagittal imbalance (a syndrome in which the patient is only able to stand with the weight-bearing line in front of the sacrum) has many etiologies. The most commonly reported technique for correction is the Smith-Petersen osteotomy. Few reports on pedicle subtraction procedures (resection of the posterior elements, pedicles, and vertebral body through a posterior approach) are ...
