This application provides an orthotic rod, an orthotic system, and a control method. The orthotic rod includes a rod body and a sensor array. The sensor array includes multiple magnetic passive sensors. During spinal correction, the orthotic rod provides continuous and stable guiding force, adapting to the laws of human growth and development, guiding the deformed spine to gradually return to normal, reducing the number of surgeries and trauma, and preserving the normal growth space of the spine and thoracic cage. Moreover, the sensor array can monitor changes in spinal shape in real time, objectively quantifying the spinal correction status without relying on medical imaging, eliminating dependence on doctors' clinical experience, and achieving unified and standardized spinal correction assessment. In addition, the use of magnetic passive sensors eliminates the need for complex electrical systems such as power supplies, circuits, and processors inside the orthotic rod, resulting in a simple structure that does not affect the strength of the rod body. It also has good biocompatibility and long-term stability, making it suitable for long-term implantation as a growth brace in the human body.
