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...

To the authors' knowledge, this is the first article to present a pedicle subtraction osteotomy in the lumbar spine to correct and stabilize a high-grade isthmic spondylolisthesis, which poses many challenges with regard to treatment options and outcomes. The optimal surgical treatment for high-grade spondylolisthesis is controversial, but the goals of treatment are to stabilize the affected sp...

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 ...

STUDY DESIGN: A description of pedicle subtraction osteotomy for correction of kyphotic deformity of the cervical-thoracic spine and a prospective evaluation of the surgical outcomes. OBJECTIVES: To describe the surgical technique and the postoperative results of pedicle subtraction osteotomy in the upper thoracic spine and the cervical-thoracic junction. SUMMARY OF BACKGROUND DATA: Pedicle sub...

BACKGROUND CONTEXT A pedicle subtraction osteotomy can be considered as part of the surgical treatment of a symptomatic sagittal imbalance. The literature on the use of this technique is limited and thus far not applied to a rigid thoracolumbar hyperkyphosis. PURPOSE To evaluate our preliminary results of a pedicle subtraction osteotomy as an adjunctive tool in the surgical treatment of thora...

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 describ...

and accessory rods at PSO level. Testing evaluated (1) accessory Study Design. In vitro cadaveric biomechanical study. Objective. To assess effects of 4-rod reconstruction, rod material, and anterior column support on motion and surface rod strain in a pedicle subtraction osteotomy model. Summary of Background Data. Pedicle subtraction osteotomy (PSO) can correct significant sagittal deformity ...

STUDY DESIGN Author experience and literature review. OBJECTIVES To investigate and discuss decision-making on when to perform a Smith-Petersen osteotomy as opposed to a pedicle subtraction procedure and/or a vertebral column resection. SUMMARY OF BACKGROUND DATA Articles have been published regarding Smith-Petersen osteotomies, pedicle subtraction procedures, and vertebral column resection...
