Özet

The aim of this study was to compare the biomechanical properties of minimal invasive sliding antirotator compressive hip screw (MIS-A-CHS), and multiple cannulated screws (CS) on a Pauwels type 3 femoral neck fracture model. Methods: A Pauwels type 3 vertical femoral neck fractures was created on 12 third-generation proximal femur models which were divided into two equal groups. The fracture was fixed with three CS in the first group, and MIS-A-CHS in the second group. The axial and rotational stiffness and maximum compression effect were compared between the groups. Results: The axial and rotational stiffness and maximum compression were significantly higher in MIS-A-CHS group (912.5 N, 540 N and 10.2 N/m, respectively) than the CS group (627.5N, 380 N, and 3.9 N/m, respectively). Conclusion: MIS-A-CHS appears to be a more secure fixation method in Pauwels type 3 femoral neck fractures than the CS. © 2014 Turkish Association of Orthopaedics and Traumatology.
