The positions of the Kirschner wires after the surgeries were evaluated by x-ray and CT scan. All data were measured by AutoCAD2010 (Auto Desk, USA) and presented in the form of mean ± standard deviation (SD). Statistics software Prism 6.0 (GraphPad Software, US) was employed to analyze the data. Measurement data subject to or approximately subject to normal distribution were expressed as mean ± SD, and paired-T-test was used to compare the preoperative Neck-Shaft Angle (NSA) and the postoperative Stem-Shaft Angle (SSA).
Measurements have been recorded as follow: (1) Stem-shaft angle (SSA):the angle between the axial line of the femur shaft and extension line of the Kirschner wire; (2) lateral offset: the acute angle between the central axis of the femoral neck and the implanted Kirschner wire in the coronal plane; It is used to evaluate whether the guide wire has varus or valgus. (3) horizontal offset: the acute angle between the central axis of the femoral neck and implanted Kirschner wire in the transverse plane. It is used to evaluate whether the guide wire has antero-posterior deviation.

Upon completion of each exposure, visible access to specific anatomic landmarks was assessed. These included coronoid tip, anteromedial facet, coronoid base, and the sublime tubercle with its attachment of the anterior bundle of the medial collateral ligament (MCL).
Standard surgical retractors were used to demonstrate maximal exposure of the coronoid process. Digital pictures were taken perpendicular to the dissection and analyzed using a software program (AutoCAD 2010, Autodesk). A standardized measuring ruler was placed in the field of view to set the scale for the program. The scale was set using a standard distance of 1 cm. The exposed osseous area of the coronoid process was outlined using the software program, and the number of pixels contained within that area was calculated and converted to cm² using the previously set scale. This method of measuring osseous surface area has been reported previously [14 (link)–16 (link)]. Statistical analysis was performed using a Wilcoxon signed rank sum test for nonparametric data, and significance was set at p < 0.05.

According to the sales ranking in the Chinese market, 78 SUVs with Euro NCAP test results were selected for this study. These SUVs were released from 2005 to 2016, and the release time distribution was shown in Figure 1(a). The overall length, overall width, and overall height of these SUVs were 4623 ± 212 mm, 1865 ± 66 mm, and 1706 ± 62 mm, respectively (Table 1).
The side contour line (main styling feature line) of a vehicle, which can be extracted from a side-view drawing, is the most important styling feature line of the vehicle. It determines the total feel and style of the vehicle and is the main feature line determined during the styling design stage [17 ]. Therefore, this study primarily investigated the relationship between the main styling feature line and pedestrian head injuries. Because the front structures (bumper, grille, and hood) of a vehicle compose the main parts that come in contact with a pedestrian during a collision, only the front section of the side contour line of each sampled SUV model was investigated in this study. The side contour line of a SUV was extracted from its side view and then was scaled to its actual size based on overall length and height in AutoCAD software (AutoCAD 2010, Autodesk Inc., San Rafael, CA). Seventy-eight side contour lines were illustrated in Figure 1(b).
