Abstract:
[Objective]A new device of gear-distraction plate (GDP) for spine reduction and fixation was designed and its biomechanical characteristics was evaluated.[Method]The GDP implants were made of titanium alloy (TC4,Ti6AL4V) and the instruments were made of stainless steel after design.Eighteen fresh calf lumbar specimens were randomly divided into three groups, the GDP group had a biomechanical test contrast to control group(CD, Steffee) in load-responsive change, load-displacement, strength, stiffness, torsion intensity and ultimate strength.[Result]Results It is better than control group in load-responsive change, load-displacement, strength, stiffness, torsion intensity and ultimate strength, there was a significant difference between them (P
