Purpose:This prospective study aimed to investigate the epidemiologic parameters of supracondylar humeral fractures in children admitted to a teaching institution of a developing country primarily catering to rural population,to find any preventable cause of such injuries.Methods:All suspected cases of supracondylar humeral fracture reporting to emergency or outpatients department were analysed for various epidemiologic parameters including age,sex,laterality,time of presentation,associated injuries,neurovascular complications and classification over a period of four years.Results:We analysed a total of 263 patients and most of the fractures were seen in 5-8-year age group with a mean of 7.9 years.A total of 157 cases were males and non-dominant extremity was involved in 65％ of fractures in our series.Fall on outstretched hand was the predominant cause of injury and fall from rooftop was the predominant mode.In all patients,36.12％ reported to our hospital 1 week after injury,39.92％ presented to hospital within 48 h after trauma and the remaining 23.95％ presented 48 h to 1 week after trauma.None had a bilateral injury.Gartland type 3 fractures constituted 54.37％ of patients,followed by type 1 (23.95％) and type 2 (21.67％).Conclusion:Almost one fourth of supracondylar humeral fractures in children can be prevented by installing railing of rooftops and stairs.It is necessary to educate people on hazards of treatment by traditional bonesetters.Moreover,the children with supracondylar humeral fractures should be screened for associated injuries.
