Abstract：Objective To analyze clinical effects of locking plates fixation combined with allograft for the treatment of Sanders type ⅡandⅢcalcaneal fractures.Methods From June, 2011 to June, 2013,50 patients with Sanders type Ⅱand Ⅲ calcaneal fractures were treated with locked plate fixation combined with allograft.There were 25 patients in Sanders typeⅡgroup.The clinical effects of two groups were compared.Results All cases had been followed up for 12~18 months, with an average of (14.34 ±2.82)months.Sanders typeⅡgroup had an average bohler angle of (33.46°±4.22°) and an average Gissane angle of (114.26°±3.83°) after surgery;Sanders typeⅢgroup had an average bohler angle of (32.14°±3.85°) and an average Gissane angle of (122.58°±4.32°) after surgery;the postopera-tive bohler angle and Gissane angle of two groups were improved significantly compared with preoperative bohler angle and Gissane angle ( P<0.05).Sanders typeⅡgroup had poor healing in 1 case, with an average fracture healing time of (11.6 ±3.5 ) weeks and Maryland good rate of 92%;Sanders type Ⅲgroup had poor healing in 2 cases, with an average fracture healing time of (12.1 ±3.2 ) weeks;and Maryland good rate was 88%, including 14 excellent cases , 8 relatively good cases , and 3 normal cases.In two groups of postoperative in-cision, healing time and was compared.There was no statistically significant difference of postoperative incision , healing time and Maryland good rate between two groups ( P >0.05 ).Conclusion Locking plate combined with allograft for the treatment of Sanders type ⅡandⅢcalcaneal fractures has the similar clinical curative effects.The key is anatomical repositioning , reasonable bone graft and strong fixation.
