Two common complications that occur in cervical surgery are malalignment, particularly after multilevel laminectomies, and nonunions. In both clinical situations, prevention and early recognition are critical in its respective clinical management. In postlaminectomy kyphosis, the prevailing cause is an alteration in the normal spinal biomechanics. The exact incidence is unknown; however, when t...

BACKGROUND: Idiopathic scoliosis is accompanied by postural alterations, instability of gait, and functional disabilities. The objective was to verify radiographic parameters (coronal sagittal) adolescents with idiopathic (AIS) pre- post-surgery direct vertebral rotation (DVR), associated type 1 osteotomies in all segments (except the most proximal) 2 periapical vertebrae curves. METHODS: A pro...

BACKGROUND Clinical sagittal plane assessment of the thoracic kyphosis angle is considered an essential component of the postural examination of patients presenting with upper body pain syndromes. Cervical headaches and conditions involving the shoulder, such as subacromial pain syndrome, have all been associated with an increase in the thoracic kyphosis. Concomitantly a decrease in the thoraci...

Introduction: Children with severe kyphosis are prone to developing neurologic compromise, poor respiratory function and possible early death. Early identification and surgical intervention has proven to be effective. However they carry the highest surgical risk of all the spine deformities. Objectives: To present the surgical results and complications of patients with severe kyphosis treated a...

This article is a comparative study. The aim of the study is to investigate the difference of sagittal alignment of the pelvis and spine between patients with thoracolumbar kyphosis secondary to ankylosing spondylitis (AS) and thoracolumbar fracture, and to evaluate the role of sacropelvic component in AS patients' adaption to the changes in sagittal alignment. Advanced stages of AS are often a...

The purpose of this study was to measure and describe postural aberrations in chronic and acute low back pain in search of predictors of low back pain. The sample included 59 subjects recruited to the following three groups: chronic, acute, or no low back pain. Diagnoses included disc disease, mechanical back pain, and osteoarthritis. Lumbar lordosis, thoracic kyphosis, head position, shoulder ...

This study was to investigate the clinical and radiographical outcomes of anterior spinal column reconstruction using structural femoral shaft allografts in osteoporotic patients. Retrospective analyses of medical records, radiographic parameters, and postoperative complications were performed in twenty-one patients who underwent anterior spinal column reconstruction surgery for osteoporotic ve...
