Augmentation of Pedicle Screw Fixation with a Bioactive Cement
نویسندگان
چکیده
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. In severely osteopenic bone, pedicle screw use may be ruled out completely.

Study Design Biomechanical study of pedicle screw fixation in osteoporotic bone. Objective To investigate whether it is better to tap or not tap osteoporotic bone prior to placing a cement-augmented pedicle screw. Methods Initially, we evaluated load to failure of screws placed in cancellous bone blocks with or without prior tapping as well as after varying the depths of tapping prior to screw ...

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...

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...
