PURPOSE: The purpose of this study was to evaluate a new treatment method, which was using intraoperative skin traction and Steinmann(S)-pin for anatomically reduction by gentle manipulation to treat the displaced supracondylar fracture of the humerus with percutaneous pinning. MATERIALS AND METHODS: Clinical analysis was performed on thirty displaced supracondylar fractures (Gartland type III) of the humerus patients with a minimal three month follow up, who were treated percutaneous pinning after reduction with by intraoperative skin traction and S-pin. Clinical results were analyzed according to the Flynn grading system. RESULTS: According to the Flynn grading system, excellent results were obtained in 12 cases (43%), good in 14 case (47%), fair in 4 cases (10%), poor in 0 cases (0%) and we obtained all satisfactory results. There was one case which was reoperated for closed reduction and percutaneous pinning repeatedly due to reduction loss and no case with conversion to open reduction. CONCLUSION: To avoid the forceful manipulation, gentle closed reduction and percutaneous pinning using intraoperative skin traction and S-pin especially for rotational correction in the displaced supracondylar fracture of the humerus is considered to be useful method because showed satisfactory results.
