“…Chen-ShengChen ve arkadaşları [18] çalışmasında ameliyatta omurgaya konulmuş ve daha sonra hasar oluşan vidaların incelemesinde hasar bölgesi olarak diş dibi bölgesini göstermektedir. Yaptığımız sonlu elemanlar analizinde de konum olarak benzer bölge çıkmaktadır.…”

“…By using the finite element model Chen et al demonstrated that screws on the caudal end were subjected to larger axial stress than those on the cephalic end, supporting the clinical finding that 75% of patients had screw breakage caudally (as in present case. In addition, screws show fatigue striations and ductile fracture around the edge 1 . Appropriate radiographs can demonstrate the screw breakage and revised spinal surgery is the mainstay of treatment when there is a broken pedicle screw 1 .…”

“…In addition, screws show fatigue striations and ductile fracture around the edge 1 . Appropriate radiographs can demonstrate the screw breakage and revised spinal surgery is the mainstay of treatment when there is a broken pedicle screw 1 . Removal of the broken screw can be a difficult task and many techniques have been described to remove deeply embedded broken pedicle screw fragments 1,3 .…”
