Several approaches (anterior, posterior, lateral, and transforaminal) are used in lumbar
fusion surgery. However, it is unclear whether one of these approaches has the greatest …

Synthetic polyurethane foams are frequently used in biomechanical testing of spinal medical
devices. However, it is unclear what types of foam are most representative of human …

Total disc replacement (TDR) is expected to provide a more physiologic alternative to fusion.
However, long-term clinical data proving the efficacy of the implants is lacking. Limited …

Study Design. Randomized Biomechanical Cadaveric Study—Level II. Objective. We aimed
to elucidate that placing lateral lumbar interbody cages that span the stronger ring …

In the thoracolumbar region, between 7% and 30% of spinal fusion failures are at risk for
pseudarthrosis. From a biomechanical perspective, the nonconformity of the intervertebral graft …

The quality of the vertebral body structures such as endplate, cortex, and trabecular bone is
important for understanding the performance of implants, particularly at the bone-implant …

bone is important for understanding the performance of implants, particularly at the bone…

Thoracolumbosacral pedicle screw systems (TPSSs) are spinal implants commonly utilized
to stabilize the spine as an adjunct to fusion for a variety of spinal pathologies. These …

Whiplash injuries remain the most common consequence of motor vehicle accidents and
account for a significant annual cost to society. In United States alone, whiplash injuries occur …

Background The efficacy of dynamic anterior cervical plates is somewhat controversial.
Screws in static-plate designs have a smaller diameter and can cut through bone under load. …
