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)
Before surgery 6.74 ± 0.77 6.41 ± 0.66 6.42 ± 0.62 6.63 ± 0.74
At 3 days after surgery 3.90 ± 0.75* 3.86 ± 0.46* 4.58 ± 0.67*#& 4.89 ± 0.51*#&
At 1 month after surgery 0.65 ± 0.49* 0.43 ± 0.50* 0.55 ± 0.50* 0.41 ± 0.50*
  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; n, number
  2. *vs. the preoperative scores, p < 0.05; #vs. the mini plate group, p < 0.05; &vs. the hollow screw group, p < 0.05
