Abstract：Objective To compare the effect of anatomical plate and locking plate for displaced calcaneus fractures.Methods Totally 70 cases of displaced calcaneal fractures (Sanders II-IV type) in our department from Jun.2011 to Jun.2013 were selected and randomly divided into anatomical plate group ( n=35) and locking plate group (n=35).The two groups were compared in operative time and fracture healing time ,Bohler and Gissane an-gle before and after surgery as well as heel length ,height and width of the calcaneus before and after surgery .Mary-land score was adopted to evaluate the function of the calcaneus after six months , and the follow-up complications were recorded.Results The operation time and fracture healing time were significantly shorter in the locking plate group than those in the anatomical plate group (P<0.01).The Bohler and Gissane angle in both groups one week after surgery were significantly greater than those before surgery (P<0.01).Bohler and Gissane angle in the loc-king plate group one week after the surgery were significantly greater than those in the anatomical plate group ( P<0.01 ) .Postoperative heel length and height of the calcaneus in both groups were significantly higher than those be -fore surgery, while the width of the calcaneus was lower (P<0.01).Postoperative heel length and height of the calcaneus in the locking plate group were significantly higher than those in the anatomical plate group , while the width of the calcaneus was lower (P<0.01).The excellent and good rate of locking plate group was significantly higher than that of the anatomical plate group (χ2 =4.8837,P=0.0271<0.05).The incidence of the postopera-tive complications of patients in the two groups had no significant difference ( P>0.05 ) . Conclusion For dis-placed calcaneus fractures ,locking plate has better clinical efficacy .
