Comparison of the efficacy of three types of Kirschner wire tension bands for ulnar olecranal fracture / 中国骨伤

OBJECTIVE@#To compare the clinical effect of three types of Kirschner wire tension band for olecranon fracture.@*METHODS@#The clinical data of 64 patients with olecranon fracture treated by Kirschner wire tension band fixation from March 2016 to May 2020 were retrospectively analyzed. Among them, 19 patients were treated with intramedullary K-wires fixation(group A) including 8 males and 11 females with an average of (48.2±18.3) years old, 3 patients were typeⅠ, and 16 patients were typeⅡ according to Mayo classification;20 patients were treated with transcortical K-wires fixation (group B) including 13 males and 7 females with an average of (43.5±20.4) years old, 3 patients were typeⅠand 17 patients were typeⅡ according to Mayo classification;25 patients were treated with perforated Kirschner wire(group C) including 15 males and 10 females with an average of (55.2±17.5) years old, 4 patients were typeⅠand 21 patients were typeⅡ according to Mayo classification. The operative time, intraoperative blood loss, times of Intraoperative fluoroscopy, fracture healing time and complications of 3 groups were compared. At the final follow-up, elbow function was assessed using the Mayo Elbow Function Scale.@*RESULTS@#There were differences in operative time, intraoperative fluoroscopy times, postoperative VAS and soft tissue irritation among the three groups(P<0.05). The operative time, intraoperative fluoroscopy times in group A and C was better than that in group B. The postoperative VAS score, skin irritability in group C was better than that of group B. The difference was statistically significant on Mayo elbow function score at the final follow-up among three groups(P<0.05), the scores of group A and C were higher than that of group B.@*CONCLUSION@#Compared with transcortical K-wires screw fixation, both intramedullary K-wires screw fixation and perforated Kirschner wire fixation, which can significantly reduce the occurrence of soft tissue irritation, reduce surgical complications and shorten the operation time.

Comparative evaluation of tensile band wire treatment and plate fixation treatment of children with olecroanon fracture / 中华实用儿科临床杂志

Objective To compare the clinical effect of tensile band wire fixation and plate fixation for treating children with olecroanon fracture.Methods Sixty-three children with olecroanon fracture at Children's Hospital of Chongqing Medical University from January 2006 to January 2014 were selected.In those cases of fracture by means of open reduction,41 cases were treated with tensile band wire,and 22 cases were treated with internal fixation with anatomical plate.Operation time,bleeding during operation,recovery time postoperatively,postoperative complications and joint function recovery were analyzed by using independent sample t-test and chi-square test.Results In the group of tensile band wire,there was no case of Kirschner wire loosening and displacement fracture.In group of steel plate,there were 2 cases of myositis ossificans.In the 2 groups,there was no case of bone nonunion.The average operation time:plate fixation group was (65.3 ± 8.4) min and tension band wire group was (58.4 ± 12.6) min,and there was a significant difference between the both groups (t =7.419,P ＜ 0.05);blood loss:plate fixation group was (5.3 ±0.8) mL and tension band wire group was (4.7-± 1.2) mL,and there was a significant difference between the both groups (t =2.595,P ＜ 0.05);fracture healing time:plate fixation group was (74.1 ± 8.4) d and tension band wire group was (61.7 ±9.3) d,and there was a significant difference between the both groups (t =10.636,P ＜0.05).With Broberg-Morrey to evaluate two groups'quality rate of function recovery,there was no significant difference in statistics with 85.3％ (35/41 cases) in tensile band wire group and 81.8％ (17/22 cases) in steel plate group(x2 =0.651,P ＞ 0.05).Conclusions Olecranon fracture in children using tension band wire fixation may be a better way,more suitable for promotion and implementation at basic hospital.
