External locking plating – a new perspective of external fixation as definitive treatment of tibial fractures
Good clinical outcomes for locking plates as an external fixator to treat tibial fractures have been reported. However, external locking plate fixation is still generally rarely performed. This study aimed to compare the stability of an external locking plate fixator with that of a conventional external fixator for extraarticular proximal tibial fractures using finite element analysis. Three models were constructed: (1) external locking plate fixation of proximal tibial fracture with lateral proximal tibial locking plate and 5-mm screws (ELP), (2) conventional external fixation of proximal tibial fracture with an 11-mm rod and 5-mm Schanz screws (EF-11), and (3) conventional external fixation of a proximal tibial fracture with a 7-mm rod and 5-mm Schanz screws (EF-7). The stress distribution, displacement at the fracture gap, and stiffness of the three finite element models at 30-, 40-, 50-, and 60-mm plate–rod offsets from the lateral surface of the lateral condyle of the tibia were determined. The conventional external fixator showed higher stiffness than did the external locking plate fixator. In all models, the stiffness decreased as the distance of the plate– rod from the bone surface increased. Increasing the thickness of the locking plate led to an increase in the rigidity of the external locking plate fixation. Finite element analysis indicated that external locking plate fixation is more flexible than conventional external fixation and can influence secondary bone healing.
