Short intramedullary nails are widely used for fixing femoral fractures - a typical geriatric trauma, insufficiently treated in Armenia or even not treated at all due to unavailability of appropriate procedures or unaffordability of the medical care for a large portion of the population. At the core of the collaborative effort between the Zaven and Sonia Akian College of Science and Engineering of AUA and the Center for Advanced Orthopaedic Studies and the Harvard Medical School is a new design for a simplified intramedullary nail. The designed system reduces the complication of the surgical kit from over 60 pieces to less than 10, reducing cost and streamlining the delivery of care. Creo Parametric CAE package was used to design the system and analyze the strength of the nail based on ASTM guidelines. Fifteen prototypes manufactured in Armenia are in the lab in Boston to undergo cadaveric bone fatigue testing.

摘要

Short intramedullary nails are widely used for fixing femoral fractures - a typical geriatric trauma, insufficiently treated in Armenia or even not treated at all due to unavailability of appropriate procedures or unaffordability of the medical care for a large portion of the population. At the core of the collaborative effort between the Zaven and Sonia Akian College of Science and Engineering of AUA and the Center for Advanced Orthopaedic Studies and the Harvard Medical School is a new design for a simplified intramedullary nail. The designed system reduces the complication of the surgical kit from over 60 pieces to less than 10, reducing cost and streamlining the delivery of care. Creo Parametric CAE package was used to design the system and analyze the strength of the nail based on ASTM guidelines. Fifteen prototypes manufactured in Armenia are in the lab in Boston to undergo cadaveric bone fatigue testing.
