Introduction: Spinal surgery is a complicated mechanical process that stops and corrects scoliosis. Monitoring the loads on the spinal instrument during and after scoliosis surgery may prevent overloading and improve patient safety. Also, collecting the data during and after provides information to better understand the biomechanics.
Objectives: This preliminary study was to validate the design of an implantable wireless sensor platform for future spinal research.
Materials and Methods: The wireless sensing system consisted of one or several sensor platforms and a base station. Each sensor platform could connect up to 8 sensors. Custom software was developed to manage the sensor network and visualize sensor values in real time. A prototype unit was developed. Experiments were performed to investigate the accuracy of the internal temperature sensor and the analog-to-digital converter, the power consumption and the range of communication.
Results: The system was operated in the 402–405 MHz frequency band which has been dedicated for the implantable medical devices by the FCC. The resolution of the temperature sensor was 0.42oC with accuracy of ±2oC for a range of 22oC to 45oC. The power consumption of the system was 0.65 mW during sleep mode and 15.6 mW with sampling rate of 10 Hz. The communication range was 100% reliable up to 3 m and dropped down to 92% when the range was 3–6 m.
Conclusion: The design of the prototype platform worked well within the FCC specifications.
Significance: A biocompatible device to measure loads during and after scoliosis surgery may help us to better understand the biomechanics of scoliosis surgery.
