Context: Supracondylar humerus fractures are one of the commonest upper limb fractures in children. Closed reduction and fixation with K wires is the most common method of treating these fractures. Stability of fixation is very important so as to prevent loss of reduction, which leads to deformity at elbow joint. Many factors contribute to the stability of fixation. Thus, considering all these factors at the fixation helps prevent loss of reduction. Aim: This prospective study was aimed at studying the functional outcome of management of supracondylar humerus fracture in the pediatric population when the management is planned as per the fracture patterns described by Bahk. Design: This is a single center prospective study conducted between July 2018 and June 2019.This study was done in a medical college and general hospital, which is a tertiary care center. Method: 100 cases of supracondylar humerus fractures in children were analyzed prospectively. Various parameters were documented to assess the functional outcome. Results: There was mean loss of motion at the elbow of 41°in conservatively managed cases and 43°in operated cases at 4th week follow up. Gradually it improved to full range.Loss of carrying angle was seen in only 8% of cases and the degree was very less. As per Flynn's criteria, 94% of cases had excellent cosmetic outcome and 6% of cases had good cosmetic outcome. Anterior humeral line passed through middle one third of capitellum in 91% of cases. Loss of Baumann's angle was seen in only 9% of cases. As per Skaggs et al criteria for loss of reduction, only 1 case had a moderate loss of reduction and 8 cases had mild displacement. Conclusion: Deciding about pin configuration for fixation should be done as per the fracture pattern and fracture comminution.
