Comparison the treatment between lateral pins and medial and lateral (crossed) pins for fixation of displaced supracondylar fractures of humerus in children after closed reduction

Closed reduction and percutaneous pin fixation is considered standard management for displaced supracondylar fractures of the humerus in children. However, controversy exists regarding whether to use pins from the lateral side or medial and lateral side of the elbow for fixation . We performed this research to know the results of two ways of treatment and to compare : 1- the risk of iatrogenic ulnar nerve injury caused by pin fixation . 2- quality of fracture reduction in terms of radiographic outcomes . 3- compare function of the elbow and other surgical complications caused by pin fixation between two ways.
