ABSTRACT Objective: Rate and compare radiographic measurements of thoracic kyphosis lumbar lordosis using anatomical dynamic parameters. Methods: Measurements were performed on lateral radiographs 10 adults both sexes without spinal disease or deformity. Thoracic measured parameters (T1-T12, T4-T12, T5-T12 L1-S1) (cervicothoracic thoracolumbar inflection point). Results: different in 30% subjec...

STUDY DESIGN Retrospective case-control study. OBJECTIVE The purpose of this study was to examine the factors of postoperative paralysis in patients who have undergone thoracic ossification of posterior longitudinal ligament (OPLL) surgery. SUMMARY OF BACKGROUND DATA A higher percentage of thoracic OPLL patients experience postoperative aggravation of paralysis than cervical OPLL patients, ...

Herniation of a thoracic disc in an acromegalic giant is reported. Degenerative changes in the spine in association with dorsal kyphosis, and the additional strain, resulted in the disc prolapse.

Osteoporotic vertebral compression fractures are common and cause pain and disability. Most osteoporotic vertebral compression fractures occur in the lower thoracic and thoracolumbar spine. Percutaneous balloon kyphoplasty through a transpedicular approach is a classic procedure performed to treat osteoporotic vertebral compression fractures. However, due to the slender morphology of the pedicl...

Study Design Retrospective analysis. Purpose Our hypothesis is that the surgical correction of adolescent idiopathic scoliosis (AIS) maintains normal sagittal alignment as compared to age-matched normative adolescent population. Overview of Literature Sagittal spino-pelvic alignment in AIS has been reported, however, whether corrective spinal fusion surgery re-establishes normal alignment r...

STUDY DESIGN Prospective clinical study. OBJECTIVE To compare the surgical outcomes of vertebral coplanar alignment (VCA) technique against the derotation maneuver with segmental pedicle screw instrumentation in patients with Lenke type 1 idiopathic scoliosis. SUMMARY OF BACKGROUND DATA Nowadays the majority of scoliosis correction begins with rod rotation and translation from the concave s...

curve flexibility in adolescent idiopathic scoliosis (ais) was one of the major concerns of spinal surgeons since the evolution of surgical correction techniques. in this respect, many tried to identify which criteria denote more rigid curve. in the present study, we aimed toward determining important factors influencing ais curve flexibility on supine bending films. we assessed radiographs of ...

conclusions patients presenting with spondyloptosis with no neurological deficit can be managed with in-situ fusion via pedicle screws, especially when presenting late and with minimal kyphosis. introduction traumatic thoracic spondyloptosis is caused by high energy trauma and is usually associated with severe neurological deficit. cases presenting without any neurological deficit can be diffic...

background: ankylosing spondylitis (as) may manifest with heterogeneous patterns according to ethnic origins. the objectives of this study were to describe the influence of various iranian ethnic origins on clinical measures in patients with as. methods: 0ne hundred sixty-three as patients diagnosed by modified new york 1984 criteria were enrolled consecutively in a cross-sectional study. the p...

BACKGROUND The prevalence of hyperkyphosis is increased in older men; however, risk factors other than age and vertebral fractures are not well established. We previously reported that poor paraspinal muscle composition contributes to more severe kyphosis in a cohort of both older men and women. METHODS To specifically evaluate this association in older men, we conducted a cross-sectional stu...
