Finite element analysis of double‐plate fixation using reversed locking compression‐distal femoral plates for Vancouver B1 periprosthetic femoral fractures

Abstract Background Internal fixation is recommended for treating Vancouver B1 periprosthetic femoral fractures. Although several procedures have been developed with high stability and union rates, long-term weight-bearing constructs are still lacking. Therefore, the aim of present study was to evaluate a double-plate procedure using reversed contralateral locking compression-distal plates fractures under full weight-bearing. Methods Single- were analysed an axial load 1,500 N by finite element analysis biomechanical loading tests. A vertical test performed prosthetic head, displacements strains calculated based on load-displacement load-strain curves generated static compression Results The revealed that significantly reduced stress concentration at lateral plate place fracture site. Under weight-bearing, maximum von Mises in 268 MPa. On other hand, single-plating method occurred defect level femur value 1,303 principal single- 0.63 % 0.058 %, respectively. Consistently, test, strain values methods 1,274.60 ± 11.53 317.33 8.03 (× 10 − 6 ), Conclusions suggests dual-plate may be excellent treatment patients fractures, allowing early postoperative period.
