OBJECTIVE To evaluate the effectiveness of 2 different types of Cotrel-Dubousset instrument systems in stabilising thoracolumbar and lumbar spine fractures. METHODS Between January 1989 and December 1993, 45 fractures in 42 patients with unstable fracture or fracture dislocation of the thoracolumbar and lumbar spines were randomly assigned to 2 surgical treatments with Cotrel-Dubousset instru...

Fixation to the sacrum and pelvis is a problem in the operative treatment of spinal deformity. Previous testing of pedicle screws address axial pull-out strength, yet how screws are loaded in vivo remains unknown. The goals of this study were to determine the loads experienced by sacral screws when loaded as part of Cotrel-Dubousset (CD) sacral instrumentation and whether different anterior gra...
