Background: fractures of the lateral condyle of the humerus represent the second most common type of fracture of the elbow in children. Although this injury is seen at all ages, it is predominately observed in children aged between 5 and 10 years. Objective: the purpose of this study is retrospective evaluation of the results of fixation of lateral humeral condyle by K-wires versus cannulated screws in children by assessment of: 1-Time to full union. 2-Range of motion.3- Percentage of complications. 4-According to Hardacre criteria. Patients and methods: a retrospective study for evaluation of the result of fixation of lateral humeral condyle fractures in children by K-wires vs cannulated screws. Our series was conducted in Al-Azher University Hospitals. 20 patients with humeral condyle fractures were treated by K-wires and cannulated screws. Results: in group A patients presented by complications as following: extension lag 1 (10%), delayed union (healing at 3–6 months) 1 (10%), revision 1 (loss of reduction at the 3rd day of operation and required revision using pin fixation) (10%), fish tail deformity 0 (0%) and 7 (70%) had no complications. While in group B: extension lag 1 (10%), delayed union 2 (20%), nonunion 1 (10%) (Not healed at greater than 6 months and reoperated using bone graft and pin fixation), revision 0 (0%), fish tail deformity 1 (10%), pin tract infection 1 (10%) and 4 (40%) had no complications. Conclusion: our study supports that screw fixation may be a viable option, with no nonunions and fewer complications than pin fixation.
