Spinal instrumentation for unstable C1-2 injury.
Seventeen patients with unstable C1-2 injuries were treated between 1990 and 1997. Various methods of instrumentation surgery were performed in 16 patients, excluding a case of atlantoaxial rotatory fixation. Posterior stabilization was carried out in 14 cases using Halifax interlaminar clamp, Sof'wire or Danek cable, or more recently, transarticular screws. Transodontoid anterior screw fixatio...

15 صفحه اولBiomechanical comparison of the K-ROD and Dynesys dynamic spinal fixator systems - a finite element analysis.
Dynamic spinal fixators, such as the Dynesys (DY) and K-ROD (KD) systems, are designed to restore spinal stability and to provide flexibility. The long-term complications of implant breakage and the biomechanics of the adjacent and the bridged levels using the KD system are still unknown. Therefore, this study aims to investigate and compare the biomechanical effects of the KD system and the DY...

reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
Biomechanical Effects of Spinal Flexibility and Rigidity on Lumbar Spine Loading: A Finite Element Analysis Study
Objective: The effects of spinal rigidity correlate positively with low back pain. Although spine flexibility has also been considered important for preventing stress-related lumbar disorders, the effects of spinal rigidity on mechanical stress during lumbar motion have rarely been reported. Methods: A biomechanical investigation and finite element analysis were conducted to elucidate the effec...
