An Engineer’S Take On The Bone-Ligament Interface: Utilizing Novel Technology To Improve Clinical Outcomes, Emma Garcia 2018 University of New Mexico - Main Campus

An Engineer’S Take On The Bone-Ligament Interface: Utilizing Novel Technology To Improve Clinical Outcomes, Emma Garcia

Shared Knowledge Conference

Ligament repair is a common surgical practice with a significant lack of viable replacements. The current gold standard for repair is the use of tendon grafts from cadavers or from another place in the patient’s body; however, these often cause more problems than they solve including immune responses or a lack of mobility in another place in the body. Synthetic replacements are of growing interest, though the ability to mimic the complex structure of the ligament and how it connects to the bone remains an obstacle. Our lab built a 3D bioprinter combined with an electrospinner to address this ...

Shared Knowledge Conference

3D bioprinting is an additive manufacturing technique that can utilize a range of bioactive materials to construct specific architectures that mimic native tissue. Near-field electrospinning (NFE) offers precise alignment control to create non-woven mats with high tensile strengths. We built a custom E-spin printer that enables layer-by-layer alternating deposition between 3D bioprinting and NFE to create composite scaffolds for the bone-ligament interface. This complex region is difficult to simulate due to its functionally graded mechanical and biochemical properties. We created NFE poly(caprolactone) highly aligned micro-fibers which formed collagen fibril-like bundles. Poly(ethylene glycol) diacrylate with decellularized bone was encased ...

The Impact Of Prosthetics On Amputee Quality Of Life, Courtney Tabor 2018 Murray State University

The Impact Of Prosthetics On Amputee Quality Of Life, Courtney Tabor

Liberal Arts Capstones

After someone has a limb amputated, their lifestyle must be rearranged to accommodate for the loss of the limb. This can include adjusting to an inability to do tasks that used to come easily and a drastic reduction in mobility. They may now require assistance with caring for themselves. As a side effect, amputees often experience a significant level of depression and anxiety related to their situation. A selection of literature was analyzed for the physiological, psychological, and sociological effects of losing a limb, and then for the ways in which a prosthetic limb would alleviate some of these issues ...
