STUDY DESIGN A new rod-plate anterior implant was designed to provide plate fixation at the cephalad and caudal-end segments of a 5-level anterior spine construct. Biomechanical testing was performed on calf spines instrumented with 5-segment anterio

This study involved the mechanical testing of single-rod segmental hook fixation and double-rod segmental hook fixation in a long-segment animal model. The goals were first to compare the flexibility of a single-rod scoliosis construct with that of a

Starting in 1952, Prof. Gavril Ilizarov, a Russian orthopedic surgeon, devised a complex method of long bone deformity correction using an external bone fixation system consisting of rings and wires. We have developed a computer-assisted surgery plan
