Does the surgery time affect the final outcome of type III supracondylar humeral fractures?

Supracondylar humeral fractures are common in the pediatric population, with displaced fractures requiring operative intervention. The purpose of this study was to look at our practice and assess whether a difference in clinical outcomes and requirement for open reduction was observed if surgery was delayed.

This was a retrospective medical record and plain radiograph review of patients admitted with type III Gartland supracondylar fractures between January 2014 and December 2015. The patients were seen for up to 12 months postoperatively, and clinical assessment was performed at this stage.

There were 116 supracondylar humeral fractures admitted between January 2014 and December 2015, 23 of which were Gartland type III. The mean age of the patients was 6 years, and the mean time from emergency department presentation to surgery was 14 h. Seven of the 23 patients required conversion to open reduction. There were no reported complications and all fractures demonstrated radiographic union. The length of time to surgery did not increase the number of cases requiring open reduction. The results demonstrated that there was no difference in clinical outcomes found between those that had closed manipulation or required conversion to open reduction, nor the time taken to surgery.

This study suggest that patients who present with type III supracondylar humeral fractures and have no neurovascular deficit, a delay in pinning of 12 h or more may not result in a significant difference in the need for open reduction or clinical outcomes.
