Purpose The purpose of this study was to investigate the epidemiology of paediatric patients sustaining supracondylar humeral fractures, to identify common mechanisms of injury and to corroborate the anecdotal evidence that fractures occur more frequently during school holidays. Methods All paediatric patients who presented to the accident and emergency department with a supracondylar distal humerus fracture over the 3-year period from 1 July 2008 to 30 June 2011 were included in the study. Data were collected from the electronic medical records and radiology picture archiving and communication system (PACS) regarding age at injury, sex, Gartland type, date of injury, mechanism and management. The dates of all school holidays during the study period were obtained from the local education authority website. Results A total of 159 patients were identified, with a median age of 6 years 1 month (range 1 year to 14 years 4 months); 53 % of patients were male. The 155 extension-type injuries comprised 46, 28 and 26 % Gartland I, II and III fractures, respectively. Sixty-five patients (41 %) were treated operatively. Six patients had either neurological and/or vascular complications; however, none had any long-term neurological compromise and none required vascular surgical intervention. The mechanism of injury was recorded in 118 cases, the majority (37 %) of which were sustained during falls from play equipment. Among the patients, 115 were of school age. The weekly incidence during school holidays was significantly higher than that during term-time (1.16 vs. 0.60, p = 0.0005). Conclusions This study demonstrates the epidemiology of paediatric supracondylar fractures managed at a district general hospital over a 3-year-period. This work supports the long-standing anecdotal evidence that play equipment carries a high risk of injury and that the incidence of supracondylar fractures is significantly higher during school holidays.
