Vertebral body height and depth and sagittal canal diameter were measured and ratios were calculated. Subjects' ages varied from newborn to 39 years.
Lateral cervical spine radiographs were available from 441 children and 192 adults. To define normal values for vertebral body height (H)/ vertebral body depth (D) ratio (H/D ratio) and sagittal canal diameter (S)/ vertebral body depth ratio (S/D ratio) in C2-7.Materials and methods. Values for vertebral body height and depth have been published only in adult men and cadavers.Objectives. Previous studies of the cervical spine have mainly focused on the sagittal canal diameter and interpedicular distances. Defining normal values is essential for reliable evaluation of growth disturbances. [Department of Radiology, Helsinki University Central Hospital, HYKS (Finland)īackground.

Reference values for radiological evaluation of cervical vertebral body shape and spinal canalĮnergy Technology Data Exchange (ETDEWEB) So the above assembly is indicated for the treatment of traumatic and osteoporotic vertebral body fracture.
A Ni-Ti shape memory alloys of vertebral body reduction fixator with assisted distraction bar may provide effective endplate reduction, restore the vertebral height and the immediate biomechanic spinal stability.
And when unsatisfied results of reduction and distraction occurred, its super flexibility could provide additional distraction strength. Relying on the effect of temperature shape memory, such an assembly could basically reduce the collapsed endplate as well as distract the compressed vertebral fracture. A biomechanic test machine was used to measure the fatigue and the stability of deformation of fixation segments. Radiographic film and computed tomographic reconstruction technique were employed to evaluate the effects of reduction and distraction. A Ni-Ti shape memory alloys of vertebral body reduction fixator with assisted distraction bar was implanted into the compressed fracture specimens through vertebral pedicle with the radiographic monitoring to reduce the collapsed endplate as well as distract the compressed vertebral fracture. To test the nickel-titanium (Ni-Ti) shape memory alloys of vertebral body reduction fixator with assisted distraction bar for the treatment of traumatic and osteoporotic vertebral body fracture.

Norton had online storage a firewall of its own than windows. Norton did not detect it, the offender emptied my entire Restore File, Outlook Express, passwords.yada…Started watching you intelligent people talking and have done 2 system restores, unloaded Norton, did 3 or 4 Search and Destroy.
I got hit by Spector Professional “Realtime” Spyware running in StealthWare.removal tool password protected.
