OrthoSpin is developing a smart external fixation system to allow real-time physician follow-up and to reduce dependency on patient compliance.

The OrthoSpin Opportunity

The market seeks an easy-to-use, automatic, external fixation device to increase patient compliance, provide physicians with real-time data, and improve treatment outcomes.

  • Physicians are excited about and validated the concept during the American Association of Orthopaedic Surgeons (AAOS) conference in March 2016.
  • Alpha version of system ready for clinical trials.
  • OrthoSpin’s market opportunity is primarily the $450 million circular and hexapod fixation device market.

The Product & Advantages

Comprised of a strut powered by a lightweight motor and a control box placed on top of the circular, hexapod fixation frame, OrthoSpin’s system automatically and continuously adjusts and lengthens the struts according to the prescribed treatment regimen — without patient involvement.

With OrthoSpin’s smart system, physicians are assured that the prescribed course of treatment is being followed. The Company’s proprietary software program allows physicians to chart patient progress and, if required, to easily change the treatment schedule.

  • Highly accurate frame adjustments
  • Reduced dependency on patient compliance
  • Real-time feedback on progress
  • Reduced revision surgeries

Accurate and continuous lengthening throughout the treatment period is expected to reduce damage to soft tissues.

Background & Market

External fixation devices are often the first line of treatment for lengthening bone, setting complex fractures, and correcting deformities. Major drawbacks of these devices are the lack of patient compliance and real-time data for improved physician follow-up during the lengthy rehabilitation period.

For treatment to be effective, patients need to adjust the frame on a daily basis. This requires manually turning the struts (rods) up to four times per day to promote bone distraction (moving two segments of a bone slowly apart), growth, and healing. Manual adjustments and complicated patient training often result in misuse and non-compliance that leads to increased pain, poor clinical outcomes, and repeat surgeries.

According to company estimates, OrthoSpin addresses the $450 million circular and hexapod fixation frame and other external fixation devices that use adjustable struts.
