Abstract
Objective : To evaluate the efficacy of Kirschner wires and tension-band fixation through posterolateral minimal incision for the treatment of displaced supracondylar humeral fractures in children. Methods: From January 2005 to December 2010,there were 62 children (38 males and 24 females,ranging in age from 2 to 14 years,averaged 6.8 years) with Gartland type Ⅲ supracondylar humeral fractures. All the injuries were caused by falling,and all the fractures were fresh injuries. The duration from injury to surgery ranged from 5 .to 20 hours. All the children were treated with open reduction through a posterolateral minimal approach, Kirschner wires and tension-band fixation, and were fixed with plaster at 90 degree of elbow flexion, forearm supination, and palms facing upwards. The Kirschner pins and wires were removed after fractures healing. The Flynn's criterion was used to evaluate therapeutic effects. Results;The operation time ranged from 30 to 50 min (averaged 45 min). All the patients achieved solid union. Sixty patients were followed up, and the mean follow-up time was 15 months (ranged from 6 to 24 months) . At the 6th month after operation,48 patients got an excellent result,9 good,3 bad (light cubitus varus with varus angle about 6 degree,without infection on function) according to Flynn's criteria. There were no complications such as procedure-related pin tract infection, iatrogenic nerve and vascular injuries and myositis ossificans. Conclusion: The Kirschner wires and tension-band fixation through posterolateral minimal incision approach can abtain clearer surgical field, simple in operation, and few wound complications. Therefore, this modified treatment is an effective and reliable method for pediatric displaced Gartland type III supracondylar humeral fractures.关键词
