Abstract:
BACKGROUND: The posterior anatomical locking plate has obtained excellent fixing performance in the treatment of complex fractures of the distal tibia; however, there are many drawbacks such as nail and plate broken, and the related rules are never reported. OBJECTIVE: To establish a finite element model of posterior anatomical locking plate for distal tibia and to provide references for its design and improvement. METHODS: The imaging data of a male patient aged 34 years old (body mass: 68 kg) with fracture on the left distal tibia were imported into Mimics16.01 software, and the proposed reconstruction parts were determined based on the default threshold of the software. The files were imported into the Ansys11.0 software, the distal tibial surface was fixed, and a force of 340 N was vertically loaded on the supine surface of the horizontal section of the large tibial shaft. RESULTS AND CONCLUSION: There was completely connected with the stepped surface of nut and screw thread portion in locking steel plate. The strain on the plate depended on the stress values. The posterior anatomical locking plate for distal tibia was more favorable for the fixation at the fracture site and could reduce the fixed plate and screws loosening, both of which could affect the fixed efficacy.
