Although vertebroplasty (VP) using polymethylmethacrylate (PMMA) is thought to be an effective procedure for osteoporotic vertebral compression fractures, several complications have been reported. In this paper, we present three patients who developed local kyphotic deformity as a result of late collapse of the cemented vertebrae. In all patients we safely removed the PMMA block through an ante...

INTRODUCTION Schwannoma is a relatively common benign spinal cord and/or cauda equina tumor; however, giant cauda equina schwannoma with extensive scalloping of the lumbar vertebral body is a rare pathology, and the treatment strategy, including the use of surgical procedures, is controversial. In this report, we present a rare case of a giant lumbar schwannoma of the cauda equina with extremel...

Exposure of murine embryos to teratogenic doses of retinoic acid (RA) induced homeotic transformations of vertebrae. Posterior transformations occurred along the complete body axis after RA administration on day 7 of gestation and were accompanied by anterior shifts of Hox gene expression domains in embryos. Anterior transformations of vertebrae in the caudal half of the vertebral column were i...

perosomus elumbis is an occasional congenital anomaly ofcattle, swine, sheep, and dogs with unknown etiology. thiscongenital abnormality occurs in both sexes. a dead holsteincalf characterized by musculoskeletal and external genitaliaabnormalities was referred to the large animal hospital ofuniversity of tehran. radiographic evaluation and subsequentdissection revealed that the vertebral column...

RATIONALE Congenital scoliosis due to a hemivertebra creates a wedge-shaped deformity, which progresses and causes severe spinal deformities as an individual grows. The treatment of congenital scoliosis focuses on early diagnosis and appropriate surgical management before the development of severe deformity. PATIENT CONCERNS We report the case of a 4-year-old male child with a left thoracolum...

Spondylitis is a reemerging epidemic spinal infection in male broiler chickens (5 to 7 weeks of age) as well as broiler breeder roosters (15 to 18 weeks of age). Among various causative agents, Enterococcus species and in particular E. cecorum, a gram-positive bacterium as a gastrointestinal flora of birds, have mostly been isolated. On late September 2015, a number of 10 week...

The vertebral column is situated in the median line, as the posterior part of the trunk. It (backbone) consists of a series of 26 individual irregular bones called vertebrae, separated by fibrocartilaginous intervertebral discs and are secured to each other by interlocking processes and binding ligaments. There are 7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral, and 4-5 fused coccygeal verte...

STUDY DESIGN A systematic quantitative review of the literature. OBJECTIVE To compare combined anterior-posterior surgery versus posterior surgery for thoracolumbar fractures in order to identify better treatments. SUMMARY OF BACKGROUND DATA Axial load of the anterior and middle column of the spine can lead to a burst fracture in the vertebral body. The management of thoracolumbar burst fra...

The left renal vein (LRV) has many developmental variations; the two most common are the circumaortic and the retrocaval. Anterior nutcracker syndrome is the compression of the LRV between the aorta and superior mesenteric artery, whereas posterior nutcracker syndrome occurs between the vertebral column and the aorta. An adolescent male (aged 16 years) was referred to the emergency department f...
