Treatment of displaced supracondylar humeral fractures among children: crossed versus lateral pinning.
This retrospective study evaluated different pinning configurations used in the treatment of displaced supracondylar humeral fractures among children, mainly regarding maintenance of fracture reduction and avoidance of complications. The fractures (41 type II and 67 type III) of 108 children (mean age 6.48 years) were treated by closed reduction and percutaneous pinning: 37 with crossed pins, 37 with two lateral pins and 34 with two lateral and one medial pin. Mean follow-up period was 7.4 months. Type III fractures fixed by two lateral pins were found significantly prone to postoperative instability, late complications and need for medial pin fixation. There was a significant relation between either delay to surgery or postoperative instability and occurrence of complications. Final outcome was significantly poorer in type III than in type II fractures. Fixation by two lateral pins only is not recommended for treating type III supracondylar humeral fractures, but could be used initially to fix severely unstable fractures to allow extension of the elbow before inserting a medial pin. Every effort should be made to avoid iatrogenic ulnar nerve injury while inserting the medial pin.
