This was a randomized controlled trial of 28 children 1 year to 12 years of age with closed totally displaced supracondylar humeral fracture. The purpose of the study was to compare closed reduction and pinning (group A) and open reduction and pinning (group B). Each group consisted of 14 children. The general characteristics of both groups (age, sex side, displacement, nerve injury preoperatively) were statistically the same (P > 0.05). All cases healed with good alignment without cubitus varus, without infection and with a good range of motion except for one. The mean +/- standard deviation of the Baumann's angle difference between the injured and uninjured side were 2.32 +/- 1.6 degrees in group A (range, 0-6.5 degrees) and 2.45 +/- 1.8 degrees in group B (range, 0-6.5 degrees). This difference was statistically not significant (P = 0.8). By Flynn criteria, group A had good to excellent results in 100%, and group B had good to excellent results in 93% and fair in 7%. This difference was not statistically significant (P = 1). The satisfaction score (0-10) was significantly higher in group A for both parents' and evaluator's (blinded to treatment) perspective (P = 0.017 and 0.019, respectively). The author concludes that both treatments gave good results. Closed reduction should be performed first and, if it fails, then open reduction can be performed. This will produce good results in the hands of an experienced surgeon.
