Scheuermann kyphosis is a structural deformity of the thoracic or thoracolumbar spine that develops prior to puberty and deteriorates during adolescence. There is limited information on its natural history but many patients are expected to have a benign course. Severe kyphosis can progress into adult life and cause significant deformity and debilitating back pain. Conservative treatment include...

With accumulated surgical experience, the contraindications to laparoscopic surgery have been decreasing. Reduced port laparoscopic surgery has been widely adopted for a variety of diseases. However, surgery in patients with anatomic deformities are still a challenge for surgeons, specifically abdominal surgery in patients with severe kyphosis. A 71-year-old man with a diagnosis of ascending co...

BACKGROUND Thoracolumbar junction (TLJ) is the transitional area between the lower thoracic spine and the upper lumbar spine. Vertebral compression fractures and proximal junctional kyphosis following spine surgery often occur in this area. Therefore, the study of development and mechanisms of thoracolumbar junctional degeneration is important for planning surgical management. This study aimed ...

In 1968 a technique of osteotomy-excision of the lumbar spine for congenital kyphosis in myelomeningocele in the newborn was described and the initial results were reviewed (Sharrard 1968). Since then the technique has been extended for the management of increasing kyphosis in older children in whom the operation had not been done immediately after birth. This paper describes the progressive de...

backgroundsitting on inappropriate benches, as well as the poor posture (body position) during the years of growth, can lead to spinal disorders, fatigue and discomfort in students. this study aimed to investigate the relationship between features of desks and chairs and prevalence of some musculoskeletal disorders in primary school students in abadan.materials and methodsthis cross-sectional s...

Bone-marrow transplantation has increased the survival of patients with mucopolysaccharidosis-I. We describe the spinal problems and their management in 12 patients with this disorder who have been followed up for a mean of 4.5 years since transplantation. High lumbar kyphosis was seen in ten patients which was associated with thoracic scoliosis in one. Isolated thoracic scoliosis was seen in a...

Proximal functional kyphosis (PJK) is a common complication (26-39%) following multilevel instrumented fusion for spinal deformities. It is defined as a focal segmental kyphosis of more than 10 degrees between upper instrumented vertebra (UIV) and 2 levels cranial to UIV (UIV+2); and a focal increase in kyphosis of more than 10 degrees between UIV and UIV+2 [1]. Although the clinical impact of ...

It is unclear whether osteoporosis itself is a main risk factor for delayed wound healing after tooth extraction in humans. In this study, we evaluated the association between experience of delayed wound healing after last tooth extraction and self-reported kyphosis, with the possibility of having vertebral fractures, in Japanese patients. Among the 1,504 patients who responded to the structure...

among the deformities of the spine in sagittal plane, kyphosis is one of the most important cases in the study of postural control from the mechanical standpoint because the smallest deviation of upper limb, that is almost 60 percent of total body weight in standing position, causes displacement of body center of mass to forward and finally will causes weaker balance performance in kyphotic ind...

AIM Conservative treatment is a frequently used treatment modality for traumatic thoracolumbar fractures. However, not many studies evaluating radiological and clinical results of conservative treatment are found. The aim of this study was to determine the risk factors, and compression and kyphosis rates after 1 year in patients with AO type A thoracic, thoracolumbar, and lumbar fractures treat...
