Table 5 Postoperative recovery and complications 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)
Fracture healing time (week) 10.1 ± 1.3 10.8 ± 1.0 13.4 ± 1.3*# 13.0 ± 1.6*#
elbow flexion and extension (°) 114.6 ± 6.5 115.4 ± 8.1 95.7 ± 8.1*# 94.4 ± 7.7*#
forearm rotation (°) 126.0 ± 7.3 127.7 ± 6.0 103.9 ± 4.2*# 102.5 ± 3.8*#
Incidence of complications 0 (0%) 2 (4.55%) 20 (32.26%)*# 10 (37.04%)*#
  1. Notes: measurement data or counting data were presented as mean ± standard deviation or number of cases; one-way analysis of variance (ANOVA) with replicate measurement or chi square test were used to compare multi-group data
  2. * vs. the mini plate group, p < 0.05; # vs. the hollow screw group, p < 0.05
