척추고정용 형상기억합금 동적안정기기의 생체역학적 성능 평가 = Biomechanical Evaluation of SMA Dynamic Stabilization for Spinal fusion

다국어 초록 (Multilingual Abstract)

In this study, a commercial fixation device, BioFlex, which was designed with shape memory alloy(SMA) for dynamic stabilization of spine was biomechanically evaluated. The finite element model of intact lumbar spine from L1 to S was developed using CT images. Also, four FE models of 2-level(L4-L5-S) and 3-level(L3-L4-L5-S) posteriori fixation using titanium(Ti) rod and BioFlex(SMA) rod. The rotations of bone segments in the intact model and four models were predicted. Although the rotations of the BioFlex fixation model were smaller than those of the intact model, they were relatively larger than those of Ti fixation. The present can be applied for not only evaluation of the stability of interbody fixator, but also development of new implant.
