Background: Expandable devices for transforaminal or posterior lumbar interbody fusion (TLIF
and PLIF, respectively) may enable greater restoration of disc height, foraminal height, …

The goal of in vitro cyclical loading studies in spine biomechanics is to provide empirical
data related to the long-term efficacy of spinal implants. Ultimately, these studies are used to …

The advent of thermoplastic semicrystalline polymeric materials in the design of medical
devices has allowed for the widespread use of polymeric interbody spacers for spinal …

This chapter seeks to explore how biomechanical studies positively influence clinical procedures
by reviewing the literature relevant to three of the largest modalities in spinal surgery: …

Degenerative conditions of the spine benefit from a methodical approach for the management
of patients with chronic low back pain when offered surgery. Surgical solutions should …

Background: Expandable cages that allow for bidirectional expansion, in both height and
width, may offer benefits over traditional expandable cages or static cages. Effective stiffness …

Study Design. A laboratory study comparing polyether ether ketone (PEEK)-zeolite and PEEK
spinal implants in an ovine model. Objective. This study challenges a conventional spinal …

Background: Bidirectional expandable designs for lumbar interbody fusion cages are the
latest iteration of expandable spacers employed to address some of the common problems …

Methods: Using 8, formalin fixed, latex injected cadaveric heads, 3D CT reconstruction was
performed on all specimens prior to dissection. Bilateral pterional craniotomies were …

Study Design: An in vitro biomechanics study. Objective: To evaluate the efficacy of triangular
titanium implants in providing mechanical stabilization to a sacroiliac joint with primary and …
