One of the great challenges of artificial spinal disc (ASD) design lies in the reproduction of
the complex mechanics of an intervertebral disc (IVD) that is characterized by a viscoelastic …

Background Postoperative alterations in cervical spine curvature (ie loss of lordotic angle)
are frequently observed following total disc replacement surgery. However, it remains …

Physiological loading of knee cartilage is highly dynamic and may contribute to the
progression of osteoarthritis. Thus, an understanding of cartilage's dynamic mechanical …

The purpose of this study was to quantify the frequency dependent viscoelastic properties of
two types of spinal posterior dynamic stabilisation devices. In air at 37° C, the viscoelastic …

Background: The cervical spine is the most vulnerable part of the vertebral column and the
rotational movements are the most dangerous movements which may cause damages to …

Polyurethane (PU) has made a significant impact on, and enabled improvement of, the tools
available to neurosurgeons to treat brain and spine pathologies. PU has shown its utility in …

Background While first-generation articulated disc prostheses had an ideal positioning
schematically as posterior as possible because of their geometrically determined center of …

The main limitations of currently available artificial spinal discs are geometric unfit and
unnatural motion. Multi-material additive manufacturing (AM) offers a potential solution for …

Although motion-sparing procedures have led to intuitive improvements in the treatment of
degenerative joint disease in the hip, knee, and shoulder, such technology would only …

Cervical and lumbar degenerative disc disease is common in today's society and can be
associated with significant pain and disability (Taksali et al. 2004). Spinal fusion continues to …
