INTRODUCTION Giant invasive spinal schwannoma is defined as a tumor that extends over two or more vertebral levels, erodes vertebral bodies, and extends into the extraspinal space disrupting myofascial planes. Because of its rarity, there have been few published reports describing clinical features and surgical outcomes, especially in the pediatric patient population. CASE PRESENTATION We ana...

Morphological integration and modularity, which describe the relationships among morphological attributes and reflect genetic, developmental, and functional interactions, have been hypothesized to be major influences on trait responses to selection and thus morphological evolution. The mammalian presacral vertebral column shows little variation in vertebral count and therefore specialization fo...

study of the osteological development in fishes is important from fisheries, biology and aquaculture points of views. it can be used as an early bio-indicator of non-optimal rearing conditions. the caspian roach, rutilus caspicus is a native cyprinid fish of the caspian sea that its artificial propagation has fulfilled in hatcheries to recruit its natural stocks. hence, this study was conducted...

Introduction: The purpose of this retrospective study was to evaluate the results of spinal canal decompression and anterior column support via posterior vertebral column resection (PVCR), performed for eliminating the disadvantages of the anterior approach, in the management of osteoporotic vertebral fractures with neurological deficits in elderly patients. Materials and Methods: Twenty-six pa...

We reviewed 40 extensive destructive vertebral lesions in 35 patients with established ankylosing spondylitis. Of these, 31 had presented with localised pain while three had a neurological deficit. The radiographs suggested ununited fractures through either ankylosed discs (37) or vertebral bodies (3). Corresponding fractures were seen in the posterior column in 34 cases. Sixteen patients with ...

BACKGROUND Solitary fibrous tumor (SFT), a rare neoplasm, usually originates in the pleura. Extrapleural SFTs occasionally occur in the head and neck. METHODS In this study, the extirpation of a rare case of recurrent SFT invading the atlas is discussed. RESULTS Ten years after surgical resection of an SFT in the right parapharyngeal space, the patient returned with a complaint of swelling ...

BACKGROUND To compare radiologic results of posterior release, internal distraction, and final pedicle subtraction osteotomy (PSO) and spinal fusionwith one-stage posterior vertebral column resection (PVCR) in treating multi-level severe congenital scoliosis. METHODS Forty-onesevere congenital scoliosis patients were used in the study. Group A comprised 24 patients who underwent one-stage PVC...
