The relationship between bone mineral density and bone strength has been investigated as a ubiquitous property of bone. This study utilized 22 isolated vertebral body preparations which had their volumetric bone mineral density quantified and their compressive mechanics measured. Cadaveric baboon ninth thoracic vertebral body samples were investigated which ranged in age from 1 to 30 years and ...

The authors present a rare case of lumbar vertebral hemangioma extending to the epidural space with a bisected appearance and impinging on thecal sac. This 52-year-old lady presented with one year history of low back pain and bilateral leg radiation. Plain radiography showed vertical linear streaks at L2 vertebral body and axial computed tomography (CT) scan revealed small "polka dot" appearanc...

BACKGROUND Hueter-Volkmann's law regarding growth modulation suggests that increased pressure on the end plate of bone retards the growth (Hueter) and conversely, reduced pressure accelerates the growth (Volkmann). Literature described the same principle in Rat-tail model. Human spine and its deformity i.e. scoliosis has also same kind of pattern during the growth period which causes wedging in...

OBJECTIVE Traditional methods of detecting growth disruption have focused on deficiencies in the diaphyseal length of the long bones. This study proposes the implementation of vertebral measurements (body height and transverse diameter of the neural canal) from non-adults (0-17 years) as a new methodology for the identification of growth disruption. METHODS Measurements of vertebral body heig...

PURPOSE To describe a technique for percutaneous vertebroplasty of osteoporotic vertebral body compression fractures and to report early results of its use. METHODS The technique was used over a 3-year period in 29 patients with 47 painful vertebral fractures. The technique involves percutaneous puncture of the involved vertebra(e) via a transpedicular approach followed by injection of polyme...

STUDY DESIGN Despite increasing information regarding pedicular instrumentation, the transpedicular biopsy of the vertebral body has not been popularized. The precise technique for percutaneous transpedicular biopsy and the volume of the vertebral body accessible through the pedicle has not been reported. OBJECTIVE To describe the percutaneous transpedicular biopsy, its diagnostic yield, to d...

vertebra plana is a radiological diagnosis that indicates complete compression of the vertebral body.(1,2) this condition was reported in langerhans cell histiocytosis including eosino-philic granuloma,(3, 12) ewing's sarcoma,(2,13,14) tuberculosis,(15,16) vertebral osteomyelitis,(17) aseptic necrosis,(18) aneurysmal bone cyst,(19) osteosarcoma,(20) neuroblastoma,(21) acute leu-kemia,(22) rhabd...

BACKGROUND Vertebral wedging is associated with spinal deformity progression in adolescent idiopathic scoliosis. Reporting frontal and sagittal wedging separately could be misleading since these are projected values of a single three-dimensional deformation of the vertebral body. The objectives of this study were to determine if three-dimensional vertebral body wedging is present in mild scolio...
