Results of crossed and lateral pinning for treatment of supracondylar fracture of humerus in children

摘要

Crossed pinning and lateral pinning with 2 to 3 pins for fixation of displaced supracondylar fracture of the humerus in children are the main debate about the stabiKty of fixation and the risk of ulnar nerve injury. The purpose of this study is the comparing of chnical result between crossed, 2 lateral and 3 lateral pinning. We reviewed 31 cases of supracondylar fracture of the humerus in children treated with closed or open reduction and fixation with pins in our hospital. 7 cases were Gartland type E and 24 cases were type 111. The 9 type IH cases were fixed with 2-3 crossed pins and 22 cases were treated with 2-3 lateral pins. 4 cases required revision. All were type in, and successfully revised with lateral pinning. The most of revisions (3 cases) were in 2 lateral pinning group. No varus deformity occurred at the end of treatment and no difference in carrying angle, humeral-ulnar angle and range of motion was observed between the groups. In the cross pinning group, 2 of 9 (22%) had ulnar nerve injury. In conclusion, the result of 3 lateral pinning cases is comparable to cross pinning without the risk of ulnar nerve injury.
