BACKGROUND: The anchorage of pedicle screws can be challenging in the osteoporotic spine. A promising technique are cement augumented pedicle screws. The goal of this study was to gain more information regarding application of pedicle screw augmentation in Germany.
MATERIALS AND METHODS: Participants of the National German Spine Congress 2009 were invited to participate in an internet-based anonymous survey regarding application of pedicle screw augmentation. The questionnaire was related to different aspects of materials and procedures for pedicle screw augmentation. The frequency of answers was divided according to the specialty state of the surgeons: orthopaedic and trauma surgeons vs. neurosurgeons. The Mantel-Haenszel test was applied to evaluate the differences between the groups.
RESULTS AND CONCLUSION: 69 (64 %) orthopaedic and trauma surgeons and 39 (36 %) neurosurgeons participated (n = 108). Nearly 80 % of the participants use cement-augmented pedicle screws in their daily practice. Almost 2/3 of the specialists apply cannulated screws or other special screws. The Expedium (Company) screws are particularly preferred. The insertion of screws is combined with kyphoplasty or vertebroplasty in 20 % of the cases. The balloon kyphoplasty was applied most commonly. There was no statistical difference between the surgeon groups regarding the different techniques. The main indications for pedicle screw augmentation were osteoporosis, intraoperative findings as well as loosening of screws, and revision. The most frequently observed complication is cement extravasation into the spinal canal (28 %). The cost issue is considered as being important but unknown to most of the participants. It can be assumed that the use of pedicle screws in Germany is well established in spine surgery, without as yet a standard technique being established.
