Analysis of efficacy on calcaneal fracture by plate fixation combined with 64-slice CT 3D reconstruction / 医疗卫生装备

ABSTRACT

Objective To treat calcaneal fracture with plate fixation combined with 64-slice CT 3D reconstruction and to analyze the efficacy.Methods Totally 86 patients with Sanders Ⅲ and Ⅳ types of calcaneal fractures underwent surgical treatment,and 64-slice CT 3D reconstruction was used to record the length,height,width,Bohler angle and Gissane angle of calcaneus before and 1 d,2 d,3 d and 1 a after the treatment.Postoperative evaluation was executed based on AOFAS Ankle Hindfoot Scale.Results All the fractures healed,of which,there were 60 ones scored as excellence,19 ones in good condition and 7 ones in satisfactory condition with the excellence and goodness rate being 91.9％.Complications occurred in 4 patients,with 3 cases of delayed healing and one case of infection.Tbere were obviously differences between the lengths,heights,widths,Bohler angles and Gissane angles before and after the treatment,while the differences were not significant between the measured values 1 d and 1 a after the treatment.Conclusion 64-slice CT 3D reconstruction is an excellent clinical auxiliary tool,and is of great value for fracture typing,operational plan preparation,postoperative evaluation and late efficacy assessment.
