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 ...

induce type II achondrogenesis-hydrochondrogenesis, spondyloepiphyseal dysplasia congenita, and Stickler syndrome, along with Kniest syndrome . 6-8) The clinical features of Kniest syndrome include a disproportionately short stature with a short, barrel-shaped chest, kyphoscoliosis, enlargement of joints with limited range of motion, a flat face with prominent eyes, low nasal bridge, myopia tha...

it has been reported that fractures are more common in epileptic patients relative to the general population. seizures by repeated muscular contractions can increase fracture risk throughout the skeleton, but the reported papers about non traumatic vertebral fractures following a single episode of seizure are rare and mostly located in thoracic spine with only one or two vertebral fracture. the...

BACKGROUND Vertebral fractures increase the risk of new vertebral fractures; however, we are not aware of any study addressing the risk of new vertebral fractures adjacent to existing vertebral fractures. Therefore, we sought to determine the influence of the number and severity of prevalent (preexisting) vertebral fractures on the risk of new adjacent vertebral fractures and to determine wheth...

term hemodialysis and it is characterized by the accumulation of β2-microglobulin in the osteoarticular structures. In 1984, Kuntz et al. (1) first described destructive spondyloarthropathy in ten patients who received longterm hemodialysis. The lesions in that study were radiographically characterized by severe narrowing of the intervertebral disk and erosions and cysts of the adjacent vertebr...

CONTEXT Vertebral fractures are the most common osteoporotic fracture. Women with low bone mineral density (BMD) and prevalent vertebral fractures have a greater risk of incident vertebral fractures over the short-term, but their absolute risk of vertebral fracture over the long-term is uncertain. OBJECTIVE To examine the absolute risk of incident vertebral fracture by BMD and prevalent verte...

Anterior cervical procedures for neurologic decompression and fusion, including cervical diskectomy and cervical corpectomy, are commonly performed by orthopaedic surgeons and spinal neurosurgeons. These procedures are highly successful in treating most patients with persistent pain and neurologic symptoms that have not responded to nonsurgical methods. Adverse events occur infrequently, but se...

The MR imaging findings of fungal spinal osteomyelitis in three recipients of organ transplants showed hypointensity of the vertebral bodies on T1-weighted sequences in all cases. Signal changes and enhancement extended into the posterior elements in two cases. Multiple-level disease was present in two cases (with a total of five intervertebral disks involved in three cases). All cases lacked h...

An 83 years old physician, doing only office work and no exercise, presented with cauda equine, due to a large intervertebral disk hernia between L1-L2 vertebrae, after an unorthodox movement. He also had a facet syndrome, a muscular spasm in the gluteus, a small fracture in the periphery of the body of the L2 vertebra and pain in the L4-L5, due to a previous vertebral hernia five years ago. Al...

background glucocorticoids taken orally increase the risk of fractures. it has been noted that a dose as low as 2.5 mg/day increases the risk of vertebral fracture. what is less clear is the possible influence of other risk factors for osteoporosis on the presence of non-vertebral fractures in patients taking glucocorticoids. objectives a cross-sectional study, performed on 513 men and women fr...
