BACKGROUND Scheuermann's disease is regarded as the most common cause of structural hyperkyphosis within adolescents without any proper treatment. It may lead to progressive deformity and back pain which influences patient's quality of life during adolescence and adulthood. Treatment approach to Scheuermann's kyphosis has not been clearly defined due to its different definitions and obscure nat...

A n 85-year-old man with a 4-day history of generalized fatigue presented at our emergency department with worsening symptoms of fatigue and dyspnea. Electrocardiography revealed a junctional escape rhythm at a rate of approximately 50 beats/min and ST-segment elevations in the inferior leads and in V4R. Coronary angiography revealed proximal occlusion of the right coronary artery and nonobstru...

Intussusception is invagination of one portion of intestine into the adjacent portion usually the proximal into the distal. It consists of three layers of gut. The receiving layer is called the intussuscipiens, the entering and the returning layers together are called the intussusceptum. Apex is the junction of the entering and the returning layers and is usually a fixed portion of the gut. Nec...

abstract objective: to present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the harrington rod (hr) and posterior multisegmented hook instrumentation. methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with harrington technique (106 patients) or multiseg...

the purpose of this study was to examine the effect of eight weeks corrective games on kyphosis angle and postural control in kyphotic mentally retarded children. method: thirty mentally retarded girls children with increase normal thoracic kyphosis (kyphosis angle≥40) were selected and randomly divided in two groups training group (n=15 with mean average 12/06±2/8 years old, height 145±1/33cm,...

Structural kyphosis is a posterior convex deformity of the spine that may appear in childhood then worsen with growth, most notably during the pubertal growth spurt. The abnormal curvature may be smooth, defining round kyphosis, or may display a sharp angular pattern. Angular kyphosis is the more severe of the two forms. The main causes of round kyphosis are postural kyphosis and Scheuermann's ...

To better understand the biomechanical mechanisms underlying the association between hyperkyphosis of the thoracic spine and risk of vertebral fracture and other degenerative spinal pathology, we used a previously validated musculoskeletal model of the spine to determine how thoracic kyphosis angle and spinal posture affect vertebral compressive loading. We simulated an age-related increase in ...
