    3D Markerless asymmetry analysis in the management of adolescent idiopathic scoliosis
    (2018-10-24) Ghaneei, Maliheh; Komeili, Amin; Li, Yong; Parent, Eric C; Adeeb, Samer
    Abstract Background Three dimensional (3D) markerless asymmetry analysis was developed to assess and monitor the scoliotic curve. While the developed surface topography (ST) indices demonstrated a strong correlation with the Cobb angle and its change over time, it was reported that the method requires an expert for monitoring the procedure to prevent misclassification for some patients. Therefore, this study aimed at improving the user-independence level of the previously developed 3D markerless asymmetry analysis implementing a new asymmetry threshold without compromising its accuracy in identifying the progressive scoliotic curves. Methods A retrospective study was conducted on 128 patients with Adolescent Idiopathic Scoliosis (AIS), with baseline and follow-up radiograph and surface topography assessments. The suggested “cut point” which was used to separate the deformed surfaces of the torso from the undeformed regions, automatically generated deviation patches corresponding to scoliotic curves for all analyzed surface topography scans. Results By changing the “cut point” in the asymmetry analysis for monitoring scoliotic curves progression, the sensitivity for identifying curve progression was increased from 68 to 75%, while the specificity was decreased from 74 to 59%, compared with the original method with different “cut point”. Conclusions These results lead to a more conservative approach in monitoring of scoliotic curves in clinical applications; smaller number of radiographs would be saved, however the risk of having non-measured curves with progression would be decreased.

    Theoretical Time Evolution Equations for the Microstructure of Bone
    (2016) Cull, Stephen; Epstein, Marcelo; Adeeb, Samer; Sudak, Les; Federico, Salvatore; Wan, Richard
    The response of the microstructure of bone to mechanical loads will be described using a continuum theory. Understanding the response of the microstructure of bone to mechanical loading will be important, as the microstructure will be assumed to influence the mechanical properties of bone. As a result of the assumed coupling between the microstructure and mechanical properties of bone, external mechanical loads will influence the mechanical properties of bone. The influence of mechanical loads on the mechanical properties in the proposed bone model will provide insights into how specific mechanical properties will be obtained through external mechanical loading. Constitutive equations will be used to describe the response of bone to changes in temperature, mechanical deformations, and the microstructure of bone. Time evolution equations which describe the changing microstructure of bone will be proposed, that are consistent with the Second Law of Thermodynamics. Due to the assumed constitutive equations, the time evolution equations depend on the temperature, mechanical deformations, and the microstructure of bone. The time evolution equations were solved numerically for a uniaxial case study with fixed porosity. Results showed that the stiffness of bone would tend to increase along the direction of loading. The stiffness of bone would tend to decrease along the direction perpendicular to the applied load. The microstructural changes in bone will also be related to mass transfers in bone. A thermodynamic driving force for mass transfer in bone will be proposed for a solid-fluid mixture, that is consistent with the Second Law of Thermodynamics. A continuous distribution of material interfaces will be assumed to separate the solid and fluid phases of bone. The proposed driving forces for mass transfer depend on the hydrostatic stress of each phase, the Helmholtz free energy of each phase, and the chemical energy of each phase.
