  • Effects of μCT and FE resolution in expressing anisotropic properties in vertebral cancellous bone 
    Shanker, Tobias; Franceskides, Constantinos; Gibson, Michael C.; Clasper, J.; Adams, George; Zioupos, Peter (Institute of Naval Medicine, 2016-09-15)
    With an aging population lower back pain is a growing concern amongst many people. Recent developments in FE have made possible the simulation of complex geometries, such as trabecular bone. Most current techniques homogenise ...
  • Evaluation of bone excision effects on a human skull model - I: Mechanical testing and digital image correlation. 
    Franceskides, Constantinos; Leger, Thibault; Horsfall, Ian; Tozzi, Gianluca; Gibson, Michael C.; Zioupos, Peter (Sage, 2019-12-06)
    The mechanisms of skull impact loading may change following surgical interventions such as the removal of bone lesions, but little is known about the consequences in the event of subsequent head trauma. We, therefore, ...
  • Evaluation of bone excision effects on a human skull model - II: Finite element analysis 
    Franceskides, Constantinos; Gibson, Michael C.; Zioupos, Peter (Sage, 2019-12-09)
    Patient-specific computational models are powerful tools which may assist in predicting the outcome of invasive surgery on the musculoskeletal system, and consequently help to improve therapeutic decision-making and ...
  • Evaluation of bone excision on occipital area of simulated human skull 
    Franceskides, Constantinos; Leger, T.; Horsfall, Ian; Shanker, Tobias; Adams, George John; Clasper, J.; Zioupos, Peter (2016-07-13)
    Surgical effects of bone and soft tissue tumours, whether for biopsy or full excision have been researched from as early as the 1970’s [1]. These researches though have as main focus the biological (histological) rather ...
  • Simulated impact response of a 3-D printed skull, with an ellipsoidal excision, using finite element analysis 
    Gibson, Michael C.; Franceskides, Constantinos; Zioupos, Peter (European Society of Biomechanics, 2016-07)
    This paper investigates methods of determining the influence of an ellipsoidal excision (14.2x11.8 mm occipital region) on the structural integrity of a human skull when exposed to impact loading. Experimental and ...
  • Spinal Motion Segments — I: Concept for a Subject-specific Analogue Model 
    Franceskides, Constantinos; Arnold, Emily; Horsfall, Ian; Tozzi, Gianluca; Gibson, Michael C.; Zioupos, Peter (Springer, 2020-06-24)
    Most commercial spine analogues are not intended for biomechanical testing, and those developed for this purpose are expensive and yet still fail to replicate the mechanical performance of biological specimens. Patient-specific ...
  • Spinal Motion Segments — II: Tuning and Optimisation for Biofidelic Performance 
    Franceskides, Constantinos; Arnold, Emily; Horsfall, Ian; Tozzi, Gianluca; Gibson, Michael C.; Zioupos, Peter (Springer, 2020-06-24)
    Most commercially available spine analogues are not intended for biomechanical testing, and the few that are suitable for using in conjunction with implants and devices to allow a hands-on practice on operative procedures ...
  • A subject-specific analogue model for spinal motion segments 
    Franceskides, Constantinos; Arnold, Emily; Horsfall, Ian; Tozzi, Gianluca; Zioupos, Peter (European Society of Biomechanics, 2017-07-05)
    Human cadaveric tissues are incredibly variable and difficult to preserve [1], thus making frequent biomechanical testing with these materials challenging. Available funds and ethical procedures will also limit their ...
  • Subject-specific functional model of hard and soft tissues; skull and spine 
    Franceskides, Constantinos (Cranfield University, 2018)
    There is a strong demand for mechanically and morphologically accurate models of the human musculoskeletal system, particularly of the spine. Such models would have multiple applications, including surgical guides, the ...
