PURPOSE: Supracondylar fracture was known as supracondylar dilema because of complication and difficulty in treatment. Many methods were devised to prevent and minimize the complications. Among the treatment methods, closed reduction and percutaneous pinning was widely used for most of supracondylar fractures. But arguments was existed for the the pinning methods such as pinning site and number of pins. MATERIALS AND METHODS: We reviewed 44 cases of displaced supracondylar fractures treated by closed reduction and percutaneous pining. The pins were removed about 4~5 weeks after operation and range of motion was begun. All cases was reviewed restropectively and results was analysed by Flynn grading system. The pinning method was analysed. RESULTS: There were no significant clinical results among the methods of percutaneous pinnings. Even though two crossed pins from the lateral and medial condyles were preferable for most fractures. The results are that 1)At least 2 K-wires were needed. 2)Prognosis was not influenced by the pinning site. 3)The complication was prevented by accurate reduction using image intensifier during operation. CONCLUSION: Two lateral parallel pins were alternative method for marked swelling and severely displaced fractures.
