The spinous processes and supraspinous and interspinous ligaments (SSL and ISL, respectively) limit flexion and may relate to spinal curvature. Spinous process angles and mechanical properties of explanted human thoracic posterior SSL/ISL complexes were compared for scoliosis (n=14) vs. kyphosis (n=8) patients. The median thoracic coronal Cobb angle for scoliosis patients was 48°, and sagittal ...

AN 8-yr-old girl developed kyphosis and myelopathy after treatment for Ewing sarcoma. Her thoracic kyphosis (144°) had resulted in myelopathy, gait disturbance, and urinary incontinence (fig.). Halo traction had been instituted 3 months before preparing for C7–T11 posterior spinal fusion. The magnetic resonance imaging (MRI) findings are marked kyphosis of the thoracic spine, with marked narrow...

BACKGROUND Several studies have explored cervical kyphosis (CK) in adolescent idiopathic scoliosis (AIS) patients. However, few studies have evaluated the cervical alignment in these patients according to their coronal curve type. The aim of this study was to analyze the radiological features of cervical sagittal alignment in Lenke 1 AIS patients before and after surgery. METHODS This is a re...

A 38-year-old man presented with untreated congenital kyphosis associated with progressive spastic gait. To prevent progression of the spastic paralysis, rigid correction of the severe spinal deformity arising from the congenital kyphosis was performed by one-stage posterior closing-wedge osteotomy, without occurrence of neurological complications. Progression of the paralysis has not been iden...

BACKGROUND Previous studies report an increase in thoracic kyphosis after anterior approaches and a flattening of sagittal contours following posterior approaches. Difficulties with measuring sagittal parameters on radiographs are avoided with reformatted sagittal CT reconstructions due to the superior endplate clarity afforded by this imaging modality. METHODS A prospective study of 30 Lenke...

BACKGROUND AND PURPOSE Limited data exist on the natural history of thoracic kyphosis in elderly patients. The purpose of this study was to determine the statistical distribution of the thoracic kyphotic angle (TKA) measurement in older patients without vertebral body abnormalities when compared with a young population. METHODS The TKA was measured by Cobb angle on digital lateral chest radio...

Abstract Background Up to now in the surgical treatment of Kümmell’s disease combined with thoracolumbar kyphosis, little research has focused on evaluation imaging and clinical outcomes restoring normal alignment sagittal balance spine. This study aimed evaluate short mid-term radiographic kyphosis. Methods From February 2016 May 2018, 30 cases kyphosis were divided into group A B according wh...

STUDY DESIGN A retrospective clinical study was performed. OBJECTIVE The aim of the study was to show patients their pre- and postoperative body photographs, and determine the effect on postoperative patient satisfaction for thoracic and thoracolumbar sharp and round angular kyphosis. SUMMARY OF BACKGROUND DATA Previous studies have reported the normative values of pelvic sagittal parameter...

Idiopathic scoliosis (IS) is the most common 3-dimensional deformation abnormality of the spine with direct effects on the thoracic cage and can potentially affect respiratory function.The purpose of the present study was to recognize whether the 3-dimensional displacement of the spine and trunk as a consequence of IS directly influences and diminishes respiratory function in children with mild...
