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

	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*#

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

* 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
