Tissue fusion over nonadhering surfaces.

Minimally invasive sacroiliac joint fusion.

What are the benefi ts of minimally invasive sacroiliac joint fusion? Frank M. Phillips, MD: Traditionally, fusion of the sacroiliac joint has involved open exposure of the joint with direct decortication of the articular surfaces, followed by bone grafting with supplemental fixation. Minimally invasive approaches to sacroiliac joint fusion aim to reduce the morbidity associated with open appro...

Human Mesenchymal Stem Cell Morphology and Migration on Microtextured Titanium

The implant used in spinal fusion procedures is an essential component to achieving successful arthrodesis. At the cellular level, the implant impacts healing and fusion through a series of steps: first, mesenchymal stem cells (MSCs) need to adhere and proliferate to cover the implant; second, the MSCs must differentiate into osteoblasts; third, the osteoid matrix produced by the osteoblasts ne...

Growing coral larger and faster: micro-colony-fusion as a strategy for accelerating coral cover

Fusion is an important life history strategy for clonal organisms to increase access to shared resources, to compete for space, and to recover from disturbance. For reef building corals, fragmentation and colony fusion are key components of resilience to disturbance. Observations of small fragments spreading tissue and fusing over artificial substrates prompted experiments aimed at further char...

PEEK Versus Ti Interbody Fusion Devices: Resultant Fusion, Bone Apposition, Initial and 26-Week Biomechanics.

STUDY DESIGN Comparative evaluation of in vitro and in vivo biomechanics, resulting fusion and histomorphometric aspects of polyetheretherketone (PEEK) versus titanium (Ti) interbody fusion devices in an animal model with similar volumes of bone graft. OBJECTIVE Identify differences in the characteristics of fusion and biomechanics immediately following implantation (time 0) and at 26 weeks w...
