Statistical analysis All data will be statistically processed with SPSS 11.0 software (SPSS, Chicago, IL, USA). Normally distributed measurement data will be expressed as mean and SD. Non-normally distributed measurement data will be expressed as lower quartile (q1), median, and upper quartile (q3). The numeration data will be expressed as constituent ratios. The Mann-Whitney U non-parametric test will be used to compare age and course of disease between the experimental and control groups. The chi-square test will be used to compare sex differences between the two groups. The Mann-Whitney U non-parametric test will also be used to compare imaging parameters (for example, angle, height, and length), PRWE scores, healing time of fracture, and VAS scores. The chi-square test will also be used to compare the effective rate between the two groups. An alpha level of 0.05 (two-sided) will be considered statistically significant.
