A novel injectable calcium phosphate-based nanocomposite for the augmentation of cannulated pedicle-screw fixation
Polymethyl methacrylate (PMMA)-augmented cannulated pedicle-screw fixation has been routinely performed for the surgical treatment of lumbar degenerative diseases. Despite its satisfactory clinical outcomes and prevalence, problems and complications associated with high-strength, stiff, and nondegradable PMMA have largely hindered the long-term efficacy and safety of pedicle-screw fixation in o...
متن کاملAugmentation of pedicle screw fixation strength using an injectable calcium phosphate cement as a function of injection timing and method.
STUDY DESIGN Axial pullout tests using fresh cadaveric thoracolumbar vertebral bodies. OBJECTIVES To evaluate the effect of a new injectable calcium phosphate cement on the axial pullout strength of both revised and augmented pedicle screws in comparison with polymethyl methacrylate and in terms of injection method. SUMMARY OF BACKGROUND DATA Failure of pedicle screws by loosening and back ...
متن کاملCement Augmentation of Sacral Pedicle Screw Fixation
As an alternative to PMMA, a newly developed calcium triglyceride bone cement (CTBC) (Kryptonite, Doctors Research Group, USA) has been reported to have osteoconductive properties [2]. In addition, CTBC is adhesive, non-toxic, and low exothermic, all of which would be advantageous in vivo. It has also been shown to have a modulus of elasticity very similar to bone, which is drastically differen...
متن کاملAugmentation of Pedicle Screw Fixation with a Bioactive Cement
Introduction Pedicle screws are commonly used in posterior internal fixation systems to stabilise the spine for fusion procedures. Rigid fixation systems place high requirements on the load-carrying capacity at the screw-bone interface. Poor bone quality decreases the integrity of this interface, increasing screw micromotion and consequently reducing screw stability and possibly fusion success....
متن کاملA biomechanical comparison of a novel thoracic screw fixation method: transarticular screw fixation vs traditional pedicle screw fixation.
BACKGROUND Transarticular screw fixation is used in the upper cervical and lumbar spine to achieve posterior spinal stability, and its biomechanical performance has been proven to be similar to that of pedicle screw fixation. However, few studies have reported the use of transarticular screw fixation in the upper thoracic spine. OBJECTIVE To biomechanically compare transarticular screws with ...
