Table 2 Comparison of postoperative Harris scores among three groups

From: Clinical observation and finite element analysis of cannulated screw internal fixation in the treatment of femoral neck fracture based on different reduction quality

Groups 3 months 6 months 12 months
Anatomical reduction group (n = 82) 71.3 ± 5.80 82.7 ± 3.55* 85.9 ± 4.14*#
Negative buttress group (n = 62) 72.1 ± 5.59 80.6 ± 3.66* 81.9 ± 2.56*
Positive buttress group (n = 78) 72.0 ± 5.24 83.1 ± 3.40* 85.4 ± 3.74*#
P value 0.601 0.041 < 0.001
  1. *Compared with the Harris score of the same group at 3 months after surgery, the difference was statistically significant (P < 0.05)
  2. #Compared with the Harris score of the same group at 6 months after surgery, the difference was statistically significant
