Smart Sensing Implants as a Future Source of Quality Data and New AI-Driven Analytics

Description

In this presentation from the ISTA 2025 conference held in Rome, the speaker discusses the integration of smart implants in orthopedic rehabilitation, emphasizing their ability to provide continuous metrics on healing and recovery. The presentation outlines a conceptual framework where various health metrics, such as walking speed and flexion angle, are monitored over time, especially after surgeries. It highlights the limitations of current clinical practices that often blind practitioners to the details of a patient’s progress between follow-up visits, and contrasts this with the rich data that smart implants can provide.



The speaker details several innovative smart implants currently undergoing research and trials:

1. **Fracture Monitor**: This system attaches a strain gauge to a plate, measuring how the load transfers from the plate to the bone during the healing process.

2. **Zimmer Persona IQ**: An existing implant that tracks patient metrics like step count and range of motion using an integrated inertial measurement unit (IMU) for at least one year.

3. **Sensing Membrane for Lag Screw**: A device designed to detect loads and temperature changes in implants, which may indicate healing status or infection.

4. **Robotic Implants**: A concept that utilizes shape memory alloys to stimulate bone healing while monitoring progress.

5. **Passive Ultrasonic Sensors**: These are simple, low-cost sensors that detect loosening in implants through feedback mechanisms.



The presentation also addresses the challenges and opportunities in employing artificial intelligence (AI) and machine learning to analyze data generated from these implants. Techniques such as clustering analysis, change point detection, and deep learning models are proposed as means to predict complications like reinjuries or infections.



Overall, the presentation advocates for the effective integration of smart technologies in surgical recovery processes, potentially transforming postoperative care through accurate monitoring and timely interventions.
