Abstract

AIm: To improve the strength of stabilization systems currently used in osteoporotic spinal fractures, essentially by increasing the fixation force of pedicle screws. mATERIAL and mETHods: Six human cadaveric vertebrae were used. Bone mineral densities of the specimens were measured with Dual Energy X-ray Absorptiometry in order to assess the osteoporosis. All vertebrae were found to be severely osteoporotic. Standard pedicle screws were applied to left pedicles of vertebrae. Pedicle screws reinforced by fixing plugs "Dubel" were applied to right pedicles of vertebrae. Afterwards the vertebrae were embedded in acrylic casts to prevent possible fracture of the osteoporotic vertebrae and to obtain a correct vertical pull-out vector. The biomechanical pullout tests were performed with biomechanical testing machine. Pullout forces in each group were recorded and compared with Mann-Whitney U test. REsuLTs: The pedicle screws strengthened by "Dubel" were found to be four times stronger than the standard pedicle screws, in the osteoporotic human cadaveric vertebrae. CoNCLusIoN: "Dubel"-augmented pedicle screws may contribute to developing better stabilization systems for osteoporotic thoracolumbar fractures needing surgery and in the revision of the previous fusion surgeries of the spine.

Özet

AmAÇ: Osteoporotik spinal fraktürlerde güncel olarak kullanılan stabilizasyon sistemlerinin gücünü; özellikle pedikül vidalarının omurgaya daha güçlü tutunmasını sağlayarak artırmaktır. yÖNTEm ve GEREÇLER: Altı insan kadavra omuru kullanıldı. Örneklerin kemik mineral dansiteleri, dual enerji x-ışını absorpsiometri kullanılarak ölçüldü ve hepsi de ileri derecede osteoporotik bulundu. Her omurun sol pedikülüne kullanımdaki standart pedikül vidası, sağ pedikülüne ise "dübel" ile güçlendirilmiş pedikül vidası implante edildi. Daha sonra omurlar, test sırasındaki olası kırıkları önlemek için akrilik içine gömülüp biomekanik test makinasıyla çekme testleri yapıldı. Her iki gruptaki vidaların çekme kuvvetleri kaydedilip, gruplar Mann- Whitney U testi kullanılarak karşılaştırıldı. BuLGuLAR: Çalışmada, osteoporotik insan kadavra omurunda, "Dübel" ile güçlendirilen vidaların standart pediküler vidalara göre dört kat daha güçlü olduğu bulundu. soNuÇ: Pediküler vidaların "dübel"le desteklenmesinin cerrahi girişim gerektiren osteoporotik torakolomber kırıklarda ve daha önceki füzyon ameliyatlarının revizyonunda da kullanılabilecek daha iyi stabilizasyon sistemlerinin geliştirilmesi yolunda ümit verici olabileceğini düşünmekteyiz.
