Cement Augmentation of Sacral Pedicle Screw Fixation
نویسنده
چکیده
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 different than the much stiffer PMMA. These properties provide a theoretical advantage of CTBC compared to PMMA for use in vivo. However, to date, there is no peer-review published literature biomechanically comparing the screw fixation strength in CTBC versus PMMA.

Possible usage of cannulated pedicle screws without cement augmentation
BACKGROUND: The use of pedicle screws is becoming increasingly popular for spinal surgery practice as the technology advances. Screw pullout due to bone quality and loading conditions is one of the most common problems observed after pedicle screw fixation. Several solutions were studied to prevent screw pullout. These can be investigated under three main categories: screw design, expandable sc...
متن کاملPulmonary cement embolism during cement augmentation of pedicle screw fixation: a case report.
We present a case of pulmonary cement embolism during cement augmentation of pedicle screw fixation for severe degenerative scoliosis. During intra-operative C-arm fluoroscopy, a radio-opaque substance was incidentally noted to pulsate in synchrony with the patient's heartbeat. A diagnosis of pulmonary cement embolism was made. The patient was treated with coumarin for 6 months. He made a good ...
متن کاملA Biomechanical Comparison of Expansive Pedicle Screws for Severe Osteoporosis: The Effects of Screw Design and Cement Augmentation
Expansive pedicle screws significantly improve fixation strength in osteoporotic spines. However, the previous literature does not adequately address the effects of the number of lengthwise slits and the extent of screw expansion on the strength of the bone/screw interface when expansive screws are used with or without cement augmentation. Herein, four designs for expansive pedicle screws with ...
متن کاملPullout performance comparison of pedicle screws based on cement application and design parameters.
Pedicle screws are the main fixation devices for certain surgeries. Pedicle screw loosening is a common problem especially for osteoporotic incidents. Cannulated screws with cement augmentation are widely used for that kind of cases. Dual lead dual cored pedicle screw has already given promising pullout values without augmentation. This study concentrates on the usage of dual lead dual core wit...
متن کاملPullout strength of pedicle screws with cement augmentation in severe osteoporosis: A comparative study between cannulated screws with cement injection and solid screws with cement pre-filling
BACKGROUND Pedicle screws with PMMA cement augmentation have been shown to significantly improve the fixation strength in a severely osteoporotic spine. However, the efficacy of screw fixation for different cement augmentation techniques, namely solid screws with retrograde cement pre-filling versus cannulated screws with cement injection through perforation, remains unknown. This study aimed t...
