Sinus Tarsi Approach Internal Fixation in the Treatment of Sanders Type Ⅱ and Ⅲ Calcaneum Fracture / 中国微创外科杂志

ABSTRACT

Objective To explore the efficacy of internal fixation in the treatment of intra-articular calcaneum fractures via the sinus tarsi approach . Methods A retrospective study was made on 55 feet with intra-articular calcaneum fractures in 51 patients treated with open reduction and intemal fixation via sinus tarsi approach from January 2010 to June 2015.According to the Sanders classification, there were 15 feet of type Ⅱfractures and 40 feet of type Ⅲfractures. Results All the patients were followed up for a mean period of 15.7 months (range, 6-33 months).The fractures were completely healed .According to the Maryland Foot Scores , the operative effect was excellent in 43 feet, good in 7 feet, fair in 4 feet, and poor in 1 foot.The excellent and good rate was 90.9%(50/55).The postoperative width of the calcaneum , B?hler angle, and Gissane angle were significantly improved than before operation (P=0.000). Conclusion Open reduction and internal fixation via sinus tarsi approach is a simple and effective method for minimally invasive treatment of Sanders type Ⅱand Ⅲintra-articular calcaneum fractures .
