Antegrade nailing can prevent cubitus varus and valgus after pediatric supracondylar fractures with impacted columns.

Supracondylar fractures are commonly encountered in the pediatric population. An impacted radial or ulnar column may result in the deviation of the elbow axis in the frontal plane clinically seen as cubitus varus or valgus. Antegrade nailing has become a feasible alternative to treat supracondylar fractures. It is not known whether it can prevent the development of cubitus varus or valgus in the cases of fractures with impacted columns. Between 1994 and 2009, 264 supracondylar humeral fractures were treated. Nineteen patients presented with either an impacted ulnar (n = 12) or radial (n = 7) column and were included in the study. The average elbow angle in fractures with impacted radial column was 159° mean (range 153-167°) compared with 179° (range 173-184°) in fractures with an impacted ulnar column. After closed reduction and antegrade nailing, the elbow angle was restored to normal values. At follow-up examination after a mean of 3.8 years (range 2.4-7.6 years), no further changes of the humeral-ulnar angle were seen. We are able to show that antegrade nailing is a safe method to treat supracondylar humeral fractures with impacted columns.
