RESUMEN
Objective To evaluate the clinical value of application of supracondylar locked intramedullary nail under arthroscope for supracondylar femoral fractures. Methods Sixteen patients with supracondylar femoral fracture were treated by supracondylar locked intramedullary nail. After mini-incision open reductions were completed, the nails were inserted retrogradely into femoral intercondylar notch under arthroscope. Results Bony union was obtained in all the patients within 3 months. Follow-up for 6～18 months showed ranges of motion (ROM) of their knee joints were 110?or above. Conclusions Application of this nail for supracondylar femoral fracture is characterized by mini-invasion, reliability and rapid recovery. There is no need for traditional open operations on the knee joint, and no need for external fixation.
