Optimal minimally traumatic approach for the SB Charité™ Artificial Disc

a benchmarking approach to optimal asset allocation for insurers and pension funds

uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...

Minimally invasive retropleural approach for central thoracic disc herniation.

BACKGROUND The management of symptomatic thoracic disc herniation (TDH) has evolved tremendously ever since the first laminectomy was performed. The last decade has witnessed the evolution of minimally invasive approaches for TDH most of which have been posterior/posterolateral. Traditional anterior approaches involve a thoracotomy or more recently, thoracoscopic techniques. The authors describ...

The Bryan Artificial Disc

p0020The cervical spine is a linkage of specialized joints and, like other joints, may be the source of significant pain and functional incapacity with age, trauma, and subsequent degeneration. However unlike other major joints, the traditional perception is that motion in the cervical spine is not a necessity and has been routinely sacrificed for pain relief and functional recovery. For more t...
