Cadaveric Model

The purpose of this study was to develop a cadaveric model for evaluating the relative motion across joint segments in the foot under simulated physiologic loading conditions. The specific aims were to 1) Develop a multi-axis testing platform that simulates three-dimensional (3D) loading conditions through the foot and ankle complex (Achilles load, tibial compression, and internal/external rotation) in a sequential or simultaneous manner, and 2) Evaluate and compare the three-dimensional (3D) kinematics between specific bones of interest in the foot for each individual cadaveric specimen.

Biomechanical Comparison

Interest in lumbar disc arthroplasty as an alternative to fusion surgery continues to grow. The goal of disc arthroplasty is to replace the diseased disc while preserving and/or restoring motion at the operated spinal level. Different paradigms exist in the design of total disc arthroplasty devices. The purpose of this study was to compare the in vitro biomechanics of a more constrained ball-and-socket design (Prodisc-L, Synthes Spine and Maverick, Medtronic) and a less constrained mobile-bearing design (Charité, DePuy). The biomechanical performances of the disc prostheses were compared to the fused and harvested spine conditions.

The traditional approach for evaluating the biomechanics of the spine, both experimentally and computationally, is through a series of planar loading scenarios that are reduced to sagittal (flexion/extension), frontal (lateral bending), and transverse (axial) planes of movement [1]. However, coupled movements occur through daily living activities that place further demands on a spinal device beyond simple planar movements. The objective of this study was to investigate the in vitro biomechanics of the L4-L5 lumbar motion segment unit (MSU) under the coupled loading conditions, and to use the experimental data to validate a high-fidelity non-parametric finite element (FE) model of the L4-L5 lumbar MSU.
