Background Supracondylar fracture is a very common elbow injury.1, 2, 3 the commonly accepted treatment of type II and III, extension-type supracondylar fractures of humerus in children is closed reduction with percutaneous pinning 17,18,19,20 Therefore, this prospective study was conducted to compare whether lateral divergent pin construct can provide the same stability like lateral crossed pin fixation at the same time avoiding the possibility of iatrogenic ulnar nerve injury.MethodsA prospective, randomized, single Centre, study was conducted at emergency department of Cairo university hospitals from March 2012 to December 2012. 16 children with supracondylar humerus fracture Gartland type IIB and type III were treated with two techniques 2 lateral crossed (8 patients) and 3 lateral divergent (8 patients) , all of them were included for the study and analysis of results regarding Functional outcome was graded according to Flynn`s criteria and Baumann’s angle. Results 16 children were treated for displaced supracondylar fracture of humerus during the study period (4) females and (12) males, mean age was 4.62 years, The mean duration from injury to surgery is (9) hours, The mean follow-up duration was 3 months, In lateral crossed group (6) patients with excellent result, (1) good, (1) fair, in lateral divergent technique (5) patients with excellent, (1) good, (2) fair.ConclusionThere was no statistically significant difference with regard to functional outcome between the two groups. Both methods produced satisfactory results in all cases.
