Table 3 The function of elbow joint of patients with ulna coronoid fractures in the four groups

From: Efficacy of internal fixation with mini plate and internal fixation with hollow screw for Regan-Morrey type II and III ulna coronoid fractures

  Mini plate group (n = 31) Hollow screw group (n = 44) Kirschner wire group (n = 62) Steel wire suture group (n = 27)
At 1 month after surgery 73.26 ± 10.49 78.45 ± 6.51 60.13 ± 12.42*# 60.59 ± 12.39*#
At 3 months after surgery 75.48 ± 10.62 85.84 ± 5.09* 63.94 ± 12.45*# 65.70 ± 10.81*#
At 6 months after surgery 80.48 ± 10.41 90.36 ± 5.16* 68.58 ± 12.54*# 70.41 ± 11.39*#
At 1 year after surgery 84.90 ± 11.23 94.39 ± 5.68* 73.48 ± 14.05*# 72.96 ± 13.74*#
  1. Notes: Measurement data were presented as mean ± standard deviation; one-way analysis of variance (ANOVA) with replicate measurement was used to compare data at different time points within-group, while multi-group data was compared using single factor ANOVA
  2. * vs. the mini plate group at the same time point, p < 0.05; #vs. the hollow screw group at the same time point, p < 0.05
