Clinical Efficacy Of Sinus Tarsi Approach With Cannulated Screws And Mini-locking Plate For Closed Displaced Intra-articular Calcaneal Fractures

0bjective To compare the effect of sinus tarsi approach with cannulated screws and mini-locking plate for closed displaced intra-articular calcaneal fractures.Methods Totally 63 cases of displaced calcaneal fractures in our department from March.2014 to January.2016 were retrospectively enrolled and treated with either sinus tarsi approach with cannulated screws(n=37)or mini-locking plate(n=26).The two groups were compared in operative time,the follow-up complications,the B?hler angle,length and width of calcaneus before surgery and at the last follow-up.The final curative function was assessed according to the Maryland score.Results The two groups were comparable with regard to demographics(age,Sanders classification,Essex-Lopresti classification,male to female ratio etc.),The operation time were significantly shorter in the hollow screws group(P<0.05).The B?hler angle,length and width of calcaneus at the both groups were significantly greater than those before surgery(P<0.05).The Maryland score of the Sanders ? shown no significant difference between two groups(P>0.05),but the group B has a better score in the type of Sanders ?(P<0.05).The incidence of the complications in the two groups had no significant difference(P>0.05).Conclusion The sinus tarsi approach was a valuable method for the treatment of type of calcaneal fractures,with low complications.The two surgery for displaced calcaneus fractures both got a similar clinical outcome in the type of Sanders ?,but in the type of Sanders ? mini-locking plate could get a better outcome.The hollow screws had a shorter operation time.
