Fatigue microdamage accumulates in bone as a result of physiological loading. The
damage is often manifested as microcracks, which are typically 50− 100 μm long. These …

Osteoarthritis and articular fractures are commonly responsible for early retirement from
athletic performance. The subchondral bone (SCB) in those conditions is being recognized …

BACKGROUND: Pedicle screw fixation to stabilize lumbar spinal fusion has become the
gold standard for posterior stabilization. A significant percentage of surgical candidates are …

Background Recently, the MRI finding of" Modic changes" has been identified as pathologic
spinal condition that probably reflects a vertebral inflammatory process (VIP), which …

Dynamic stabilisation system for the spine (Dynesys) relies on titanium screw purchase
within the pedicle. Decision on osseointegration is important especially when the patient …

Graft subsidence following anterior cervical reconstruction can result in the loss of sagittal
balance and recurring foraminal stenosis. This study examined the implant–endplate …

Most research to date relating cumulative compression exposure in the low back to the
reporting of pain has employed a linear summation of force (load) magnitudes to obtain …

Results of in vitro studies conducted on isolated bone specimens have indicated a higher
tolerance to static load than exists when exposed to cyclic loading, when controlled for creep …

Background Failure of pedicle screw is a major concern in spinal surgery. The threaded and
unthreaded portions of the pedicle screw provide the ability to anchor and squeeze the …

Biomechanics provides a means to quantitatively consider the implications of workplace
design. The benefit of biomechanical quantification is that it can help determine how much …
