ABSTRACT
Objective To explore the methods and clinical effect of the sinus tarsus mini incision approach with percutaneous fixation technique in the treatment of Sanders Ⅱ,Ⅲ calcaneus fractures.Methods From January 2015 to May 2016,the clinical data of 64 cases with Sanders Ⅱ,Ⅲ calcaneus fractures who were treated by sinus tarsus mini incision approach with percutaneous reduction and fixation were analyzed retrospectively.The average age was 46.64±10.51 years (range,25-68) and 49 patients were males and 15 patients were females.According to Sander's classification,39 patients were Sanders Ⅱ and 25 were Sanders Ⅲ fracture.Calcaneal varus was corrected and the length,width and height of bone were reduced by sinus tarsus mini incision approach with percutaneous fixation technique.Calcaneal fracture was treated by calcaneal bone plate combined with percutaneous screw fixation.Complications and operation procedure were recorded post-operation.Anteroposterior,lateral and axial views of preoperative and postoperative X-ray and CT scan were taken to assess the classification,restoration and intertion status of fracture.Radiological assessment was performed using B(o)hler's angle and Gissane's angle.Functional outcome was assessed using the Maryland foot score (MFS).Results All of the sixty-four patients were followed up for 12-18 months (average,14.80± 2.03).After surgery,only 4 cases of superficial necrosis of the incision were found,and the incisions were all healed and no infection occurred after surgery.No tendon tenosynovitis was seen after surgery.There were no fracture displacement,internal fixation failure,and fracture deformity healing cases.The mean time of bone union was 9.44±1.38 weeks (8-12 weeks) without fracture deformity healing case.The mean time of bone union was 9.17±1.16 weeks for the 23 cases with bone graft.For the 41 cases without bone graft,the bone healing average time was 9.91 ± 1.62 weeks,and there is no statistically difference between cases with and without bone graft (t=1.936,P=0.061).B(o)hler's angle was 6.625°±4.904° (range,-5°-15°) preoperative,and improved to 31.031°± 4.660° (range,24°-40°),which had statistically significant difference (t=-28.863,P=0.000).Gissane's angle was from preoperative 76.094°±12.981° (range,55°-105°) to 127.328°±6.486° (range,115°-140°) at the time of the latest follow-up,and the difference had statistically significant (t=-28.246,P=0.000).Maryland Scoreexcellent 30 cases (22 cases of type Ⅱ,8 cases of type Ⅲ),good 27 cases (15 of type Ⅱ,12 of type Ⅲ),fair 7 cases (2 of type Ⅱ,5 of type Ⅲ).The overall good rate was 89.06% (57/64).Conclusion The tarsal sinus minimally invasive small incision reduction and internal fixation combined with percutaneous reduction and fixation technique in the treatment of ealcaneal fractures,exerts the advantages of small trauma,clear surgical exposure for reduction,reliable fixation,and low incision complications,which is applicable to treat the Sanders Ⅱ,Ⅲ calcaneal fractures.
