Abstract EN
In this study, we developed and validated a refined three-dimensional finite element model of middle femoral comminuted fracture to compare the biomechanical stability after two kinds of plate fixation: a newly designed assembly locking compression plate (NALCP) and a locking compression plate (LCP).
CT data of a male volunteer was converted to middle femoral comminuted fracture finite element analysis model.
The fracture was fixated by NALCP and LCP.
Stress distributions were observed.
Under slow walking load and torsion load, the stress distribution tendency of the two plates was roughly uniform.
The anterolateral femur was the tension stress area, and the bone block shifted toward the anterolateral femur.
Maximum stress was found on the lateral border of the number 5 countersink of the plate.
Under a slow walking load, the NALCP maximum stress was 2.160e+03 MPa and the LCP was 8.561e+02 MPa.
Under torsion load, the NALCP maximum stress was 2.260e+03 MPa and the LCP was 6.813e+02 MPa.
Based on those results of finite element analysis, the NALCP can provide adequate mechanical stability for comminuted fractures, which would help fixate the bone block and promote bone healing.
