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 after augmentation of pedicle screws with bone cement.
The authors present the very rare complication of widespread pulmonary artery cement embolism after pedicle screw augmentation with bone cement for multilevel spine fusion. A 69-year-old woman with severe osteoporosis underwent a posterior T12S1fusion because of lumbar scoliosis. After two months the superior pedicle screws loosened, and a revision spondylodesis T8L1 was performed with bone cem...
متن کاملForeign body granuloma after bone cement augmentation of pedicle screws for osteoporotic spinal surgery: A case report
Osteoporosis causes a decrease in bone mineral density. To overcome the decrease in fixation strength, a variety of techniques and devices have been developed, including cement augmentation of pedicle screws. Polymethyl methacrylate (PMMA), is commonly known as bone cement, and is widely used for implant fixation in various orthopaedic and spine surgery. In general, PMMA augmentation of pedicle...
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...
متن کاملMinimally Invasive Technique for PMMA Augmentation of Fenestrated Screws
PURPOSE To describe the minimally invasive technique for cement augmentation of cannulated and fenestrated screws using an injection cannula as well as to report its safety and efficacy. METHODS A total of 157 cannulated and fenestrated pedicle screws had been cement-augmented during minimally invasive posterior screw-rod spondylodesis in 35 patients from January to December 2012. Retrospecti...
