Purpose.
To verify the biomechanical importance with respect to the integrity of posteromedial cortex of femoral neck fracture (FNF) and demonstrate whether the modified fixation of cannulated screws (CSs) could increase the biomechanical strength.
Methods.
A total of 24 left artificial femurs were randomly divided into three groups.
The osteotomy was made in the center of the femoral neck at a 20° angle to the shaft axial.
The posteromedial cortices of femoral neck were removed in groups B and C.
In group A, 8 femurs with intact posteromedial cortex were fixed with three parallel partial thread screws (PTSs), forming a standard triangle.
In group B, the femurs were stabilized with the same fixation of CSs like group A.
In group C, two inferior PTSs were replaced by two fully thread screws (FTSs).
Results.
The lower A-P and axial stiffness and load to failure along with higher axial displacement were found in group B compared with group A (p≤0.001 for all).
Between groups B and C, the modified fixation of CSs increased A-P and axial stiffness and load to failure and reduced the axial displacement (p≤0.001 for all).
Conclusions.
We verified that the comminuted posteromedial cortex affected the biomechanical strength adversely and resulted in higher displacement.
The modified fixation of CSs characterized by two inferior FTSs could improve the biomechanical performance and buttress the femoral head fragment better.
