Purpose : We evaluated the complications, radiological and clinical results after operative treatment using a mini-plate for fixation of displaced talar neck fractures.
Materials and Methods : There were 20 cases of displaced talar neck fractures from May 2006 to December 2011; we performed a retrospective chart review of 15 patients treated by open reduction and internal fixation using a mini-plate who had more than 2 years of follow-up. According to Hawkin’s classification, there were 7 cases of type II fractures and 8 cases of type III fractures. During postoperative 12-16 weeks we checked magnetic resonance imaging. The assessment of clinical results was based on the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale.
Results : Mean union period was 11.6 weeks (10-15 weeks). Nonunion and malunion did not occur in all cases. The mean AOFAS score was 88.2 points (80-97 points). There were 5 cases of avascular necrosis. Of these, there were 3 cases of body collapse and 4 cases of post-traumatic arthritis. In the statistical analysis, there was no correlation between the elements including gender, Hawkin’s classification and union rates and clinical results.
Conclusion : Mini-plate fixation of a displaced talar neck fracture is thought to be a good technique, with a low rate of malunion and also showed satisfactory results in radiological and clinical assessment.
