The segmental heritage of all vertebrates is evident in the character of the vertebral column. And yet, the extent to which direct translation of pattern from the somitic mesoderm and de novo cell and tissue interactions pattern the vertebral column remains a fundamental, unresolved issue. The elements of vertebral column pattern under debate include both segmental pattern and anteroposterior r...

Introduction Obstruction of the third part of duodenum by superior mesenteric artery is known as superior mesenteric artery syndrome. Incidence of superior mesenteric artery syndrome following spine deformity correction is 0.5-4.7%. Till now, this syndrome after isolated kyphosis correction with vertebral column resection is rarely reported in literature. Case Report A 17-year-old male patien...

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...

CONTEXT Hemangiopericytoma is an uncommon mesenchymal neoplasm that rarely affects the spinal canal. Primary malignant hemangiopericytoma of the spinal column is extremely rare. CASE REPORT We report on a case of primary epidural malignant hemangiopericytoma of the thoracic spinal column that invaded vertebral bone and caused spinal cord compression in a 21-year-old man. The patient presented...

Background Data: Several articles reported on PVCR for correction of thoracolumbar deformities that followed tuberculous spondylodiscitis. But fewer focused fixed lumbosacral deformity secondary to L5 pathology. Study Design: A retrospective cohort study. Purpose: This article aims determine the degree spinopelvic parameters after posterior vertebral column resection (PVCR) fifth lumbar vertebr...

Vertebral involvement is no longer a contraindication for resection of superior sulcus tumors. We describe a patient who developed a kyphoscoliosis with spinal cord compression after resection of a superior sulcus tumor that invaded the vertebral column. Risk factors for spinal instability and indications for stabilization are discussed.

STUDY DESIGN Anterior and posterior vertebral body heights were measured from sequential magnetic resonance imaging (MRI) scans of adolescent idiopathic scoliosis (AIS) patients and healthy controls. OBJECTIVE To measure changes in vertebral body height over time during scoliosis progression to assess how vertebral body height discrepancies change during growth. SUMMARY OF BACKGROUND DATA R...
