AI Technical Summary

Technical Problem

Existing biodegradable bone plates have shortcomings in terms of matching degradation rate with fracture healing process, mechanical design and adaptability to dynamic biomechanical environment, individual differences, and material usage and safety, leading to the risk of secondary surgery, fixation instability and material residue problems.

Method used

By constructing a finite element model of femoral shaft fracture, applying dynamic biomechanical loads simulating the human walking cycle, and optimizing multi-dimensional parameters of the bone plate, including size, number of screws, and topology, and combining individual bone strength differences, the safe zone of the bone plate can be delineated and personalized.

Benefits of technology

The degradation rate of the bone plate was synchronized with bone healing, ensuring that the bone plate completely degrades after fracture healing, eliminating the need for secondary surgery, reducing the risk of infection, meeting the different bone strength needs of different populations, and improving mechanical stability and biocompatibility.
