Developing a Minimally Invasive Bone Fixation System for Enhanced Orthopedic Recovery

Design and Development of Minimally-Invasive Orthopedic Fracture Fixation System Using Intramedullary Sleeve and Photocurable Bone Cement

Abstract:

This Small Business Innovation Research SBIR Phase I project address the challenges associated with an increasing incidence of orthopedic injuries and surgeries. The innovative technology will stabilize and repr broken bones in both the US and globally, focusing on a minimally-invasive procedure called intramedullary nling for bone fractures treatment.

Intramedullary nling involves inserting metallic implants into the medullary cavity to stabilize bone fractures; however, this procedure is often associated with complications such as infection, rotation of limbs, and flure to achieve complete rigidity. These issues can lead to patient discomfort and significantly increased costs due to revision surgeries. The need for an intramedullary nl technology that is less invasive, cost-effective, customizable, and suitable for the patient's anatomical requirements is pressing.

The project focuses on developing a minimally-invasive intramedullary IM sleeve system coupled with an in situ, photocurable polymeric resin system. The key objectives are:

1. Design and development of a multi-layered IM sleeve prototype.

2. Synthesis and optimization of a photopolymerizable polymeric resin for the IM sleeve.

3. Development of tools and methods to remove cured polymers from the IM sleeve minimally invasively.

4. Demonstration of customized IM device in sheep cadaveric tibia bone.

This research will contribute new knowledge about designing and synthesizing novel polymer formulations with improved mechanical properties and faster setting times, which are essential for effective fracture healing. Furthermore, it establish a method for extracting the cured polymers using existing removal techniques.

For healthcare professionals, this project may lead to innovative minimally invasive treatments that significantly reduce surgical time and enhance patient recovery rates.

This award embodies NSF's mission by fostering intellectual merit and broader impacts through research and development, which is expected to drive advancements in orthopedic procedures and potentially revolutionize patient care standards.
