Factors influencing the complication rate in pediatric supracondylar humerus fractures

The aim of the study was to identify influencing factors on the complication rate in pediatric supracondylar humerus fractures (PSHF). 22 male and 19 female patients with an extension type PSHF underwent conservative and operative treatment at a single trauma department and were reviewed retrospectively. The complications were assessed and the groups of patients with and without complications were compared according to patient- and therapy-related factors. The overall complication rate was 19.5%. Two patients had a primary and 4 patients a postoperative neurological deficit. One patient developed a pin infection after open reduction and crossed pin fixation. One patient underwent early revision surgery because of insufficient initial reduction after closed reduction and crossed pin fixation. All complications appeared in the surgical treatment group. The appearance of complications was significantly associated with a higher Gartland stage. The median time between trauma and operation was significantly longer in patients without compared to patients with complications. PSHF are associated with a high rate of neurological complications. The Gartland stage and the necessity of surgical treatment are the major influencing factors on the complication rate.
