[Comparative study on curative effect of minimally invasive locking plate for the treatment of intra-articular calcaneal fractures via sinus tarsi approach].

OBJECTIVE: To compare clinical efficacy of minimally invasive locking plate and anatomic locking plate in treating intra-articular calcaneal fractures via sinus tarsi approach. METHODS: A retrospective analysis was conducted of 48 patients with intra-articular calcaneal fractures treated with surgery via sinus tarsi approach from July 2016 to June 2017. According to differernt methods of internal fixation, the patients were divided into minimally invasive locking plate group and anatomic locking plate group. In minimally invasive locking plate group, there were 14 males and 10 females, aged from 27 to 46 years old with an average age of (38.70±5.58) years old, 18 patients were typeⅡand 6 patients were type Ⅲ according to Sanders classification. In anatomic locking plate group, there were 17 males and 7 females, aged from 26 to 46 years old with an average age of (37.10±6.44) years old, 16 patients were typeⅡ and 8 patients were type Ⅲ according to Sanders classification. Operative time, visual analogue scale (VAS), postoperative complications between two groups were compared, and Böhler angle, Gissane angal, calcaneal width and height were recorded and compared between two groups at 1 week after operation and final follow up. The functional effect was assessed according to Maryland foot function score at final follow up. RESULTS: >0.05). CONCLUSION: Compare with anatomic locking plate, minimally invasive locking plate via sinus tarsi approach for Sanders typeⅡ and Ⅲ intra-articular calcaneal fractures could obtain similar reliable fixation and functional recovery with more simple operation, shorter operative time, lighter postoperative pain and less complications.
