Abstract：Objective To explore factors related to calcaneal fracture function recovery by surgical treat -ments.Methods Seventy-eight patients with calcaneal fracture treated by operation from Feb .2009 to Feb.2012 in our department were retrospectively analyzed and comprehensively evaluated according to the Maryland Foot Score .Eleven factors that might affect the surgical curative effect including age ,gender ,fracture type ,open or closed type,operation time, types of incision, operation method, intra-articular reduction effect , bone graft, postoperative B?hler angle and partial weight-bearing time were grouped ,assigned and single factor screened with logistic regres-sion analysis.Results Patients were followed up for 18 to 26 months.Forty-seven cases were excellent,18 were good,13 were fair and 8 were poor.The excellent and good rate was 75.6%.Among them,Sanders type Ⅱ and type Ⅲfractures were grouped as one .The excellent and good rate was 89.2%in this group and 33.3%in typeⅣgroup.The open fracture group included 18 feet and the excellent and good rate was 55.6%.The closed fracture group included 68 feet and the excellent and good rate was 80.9%.The excellent and good rate was 87.0%within 2 weeks after surgery and 29.4%2 weeks after surgery .The excellent and good rate of the intra-articular reset <3mm group was 87.7%and 38.1%in the≥3mm group.Postoperative B?hler angle received basic recovery in 59 feet with an excellent and good rate of 84.8% and less satisfactory in 27 feet with an excellent and good rate of 55.6%.The excellent and good rate of postoperative weight-bearing group at 8 weeks after surgery and within 8 weeks after surgery were 87.1%and 45.8%respectively.All above data had statistical significance (P<0.05). Through single factor analysis ,irrelevant factors were eliminated .Multivariable logistic regression analysis showed that effective factors included fracture type ,operation time,surgery reduction effect and postoperative B?hler angle. Conclusion Fracture type,operation time,surgery reduction effect and postoperative B?hler angle are risk factors affecting the function recovery of calcaneal fracture .We should try to avoid adverse factors to improve the surgical curative effect .
