BACKGROUND AND PURPOSE It is important to try to clarify the methodology of vertebroplasty such as amount of cement needed, how many needles to use and the significance of cement extravasation. This prospective study evaluated the potential of vertebroplasty to increase the likelihood of an adjacent vertebral compression fracture (VCF) 1 year or less after vertebroplasty, the correlation betwee...

Background: Osteoporotic compression vertebral fractures are common clinical problems. In those with refractory fractures, percutaneous cement augmentation has been suggested. The aim of this study was to evaluate the functional outcome of percutaneous vertebroplasty in Iranian patients with refractory osteoporotic fractures. Methods: We retrospectively studied 37 osteoporotic fractures in 28 p...

Since the syndrome was first described concurrently by Morquio [1] and Brailsford [2] in 1929, radiology has played a vital ro le in the diagnosis of the Morquio-Brailsford syndrome and in the management of complications of the disease. Symptoms of spinal cord compression are common. They are related to dysplasia of the dens with atlantoaxial subluxation and narrowing of the spinal canal [3-5]....

Bone mineral density of the lumbar vertebrae (L2-4BMD) in involutional osteoporosis was measured by dual photon absorptiometry to investigate its relationship with the incidence of osteoporotic vertebral fractures of the thoracic and lumbar spine. In addition to monitor L2-4BMD, the author also examined the progress of vertebral fractures during drug treatments by means of radiographs. L2-4BMD ...

BACKGROUND Clinical results have shown that different vertebral heights have been restored post-augmentation of osteoporotic vertebral compression fractures (OVCFs) and the treatment results are consistent. However, no significant results regarding biomechanical effects post-augmentation have been found with different types of vertebral deformity or vertebral heights by biomechanical analysis. ...

Percutaneous vertebroplasty (PVP) is a minimally invasive procedure widely used for the treatment of pain due to vertebral fractures of different origins-osteoporotic, traumatic, or neoplastic. PVP is minimally invasive, but the complications are not rare; however, they are in most cases not significant clinically. The most frequent is cement leakage, which can occur onto veins, paravertebral s...

the pomegranate seed oil (pso), containing 17-α-estradiol, is one of the newly found phytosterols with synergistic health effects on estrogen related physiological conditions. herein, pso was assessed for its potential improving effects on bone characteristics in a rat model of menopausal syndrome. three month old non-pregnant female wistar rats (n = 30) were either sham-operated (sham) or ovar...

BACKGROUND The key to its successful application is to determine the best entry point for the vertebral screw(s). This study aimed to provide a reference for clinical anterolateral fixation through digital measurement of computed tomography (CT) data to identify relevant anatomical positions in the middle and lower thoracic vertebrae (T4-T12) of 30 adults. MATERIAL AND METHODS We performed digi...

Vertebral artery injury may occur at the time of cervical fracture or dislocation. Congenital vertebral artery variations, especially a double vertebral artery origin, may be responsible for angiographic findings that mimic vertebral artery dissection. Two cases of cervical spine fracture with ipsilateral double vertebral artery are presented. Conventional cerebral angiography is the easiest an...

BACKGROUND AND PURPOSE We sought to identify the use of duplex and transcranial Doppler sonography in the noninvasive diagnosis of vertebral dissection. METHODS Ten patients with a diagnosis of symptomatic vertebral artery dissection confirmed by cerebral angiography were retrospectively analyzed. RESULTS Computed tomographic scanning and magnetic resonance imaging together delineated later...
