Cement 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 کاملThe Effects of Cement Augmentation Technique and Cement Volume on Pedicle Screw Fixation in Osteopenic Bone
INTRODUCTION Cement augmentation of pedicle screws has been shown to improve screw fixation in osteopenic spines. The use of polymethylmethacrylate cement augmentation has been documented in various studies using a number of different techniques: cement injection directly into an open pilot hole, through cannulated screws, using implanted sleeves, and using kyphoplasty techniques. Complications...
متن کاملScrew and cement augmentation of patella defects in knee arthroplasty
BACKGROUND At primary and revision knee arthroplasty, a defi cient patella with a contained or uncontained defect is often encountered,1,2 especially in the presence of longstanding maltracking. In these cases, reconstruction is diffi cult, leaving an unsupported implant. Following the good outcomes achieved using cement fi xation of large defects of the tibial plateau augmented with screws,3 w...
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 ...
