Efficacies of open reduction and cannulated compression screw fixation for displaced talus fracture in children

Abstract

Objective To explore the efficacies of open reduction and cannulated compression screw fixation for displaced talus fracture in children. Methods From February 2011 to September, 22 patients (16 boys and 6 girls) of displaced talus fracture with an average age of 7.4 (3.7-12.3) years were recruited. And 18 cases of injuries were due to traffic accidents and falls. All definite preoperative diagnoses were made by radiography and computed tomography (CT). Twenty-one patients underwent open reduction and cannulated compression screw fixation by incision of anteromedial foot. Only one case had combined incision of anterolateral and anteromedial foot. Fractures were immobilized postoperatively by cast. Results The average follow-up period was 1.5 (0.8-4.2) years. Cast immobilization was removed at 6 weeks post-operation and in-bed rehabilitation excises were followed by unaided walking. As evaluated by the Hawkins criteria, the functions of ankle and foot were excellent (n=18) and decent (n=4). During follow-ups, there was no occurrence of bone nonunion, osteonecrosis of talus or osteoarthritis. The appearances of feet were excellent and there was no pain. Conclusions A combination of open reduction and cannulated compression screw fixation is efficacious for displaced talus fracture in children. Key words: Talus; Bone fractures; Child
