Abstract
To fix the femoral neck fracture using screws, there are different opinions among orthopedic surgeons about screw placement. Also, the parameters of bone drilling, including the angle of the drill tip and the rotational speed of the drill, can also have an effect on the fixation strength. In this research, experimentally and with the help of simulation, the effect of three types of arrangement including triangle, inverted triangle and linear, and parameters of rotational speed and angle of the drill tip on the strength of femoral neck fracture fixation has been investigated for the first time. In experimental tests, the maximum force tolerated by for the inverted triangle arrangement is 25% and 37% higher than the triangle and linear arrangements, respectively. The rotational speed of the drill 2000 rpm compared to 1000 rpm and the tip angle of the drill 60° compared to 118° have increased the connection strength by 11 and 7.5 percent, respectively. The analysis of variance showed that the effect of the type of screw arrangement, respectively. the rotational speed of the drill and the angle of the drill tip on the fixation strength is 83.26, 6.98 and 3.24%, respectively. The results obtained from the numerical simulation showed that the proper arrangement is the inverted triangle with the drilling parameters of the rotational speed of the 2000 rpm and the tip angle of the 60°, which has endured N4782 force.
