Abstract: Objective To analyze the curative effect of traditional and retrograde insertion of talar process screws for calcaneal fracture. Methods From March 2019 to January 2021,80 patients with calcaneal fracture in our hospital were selected for the study.According to the surgical methods of patients,the subjects were divided into control group(traditional method of anterograde insertion of talar protrusion screws) and experimental group(retrograde insertion of talar protrusion screws),with 40 cases in each group.Surgical indicators(operative time,intraoperative blood loss,fracture healing time),Preoperative and postoperative Bohler Angle,Gissane Angle,VAS score,AOFAS score,QOL score,and the incidence of clinical complications in 2 groups were compared. Results The operation time of the control group(103.52±12.50) minwas higher than that of the experimental group(96.89±11.25)min.The amount of intraoperative blood loss in control group(79.58±9.13)ml was higher than that in experimental group(60.25±8.71)ml.The fracture healing time of the control group(15.52±2.51) weeks was higher than that of the experimental group(11.47±2.03) weeks,and the differences were statistically significant(P<0.05).After operation,Bohler Angle(31.08±4.22)°and Gissane Angle(125.99±4.38)°in experimental group were higher than those in control group(25.74±3.07)° and(110.48±5.12)°,with statistical significance(P<0.05).After operation,QOL score(80.04±5.29) and AOFAS score(82.55±7.46) of experimental group were higher than those of control group(68.17±4.79) and(64.03±6.14),VAS score of experimental group(1.28±0.42) was lower than that of control group(3.02±1.23).The differences were statistically significant(P<0.05).The incidence of complications in experimental group(7.50%) was lower than that in control group(15.00%),there was no statistical significance(P>0.05). Conclusion Retrograde insertion of talus process screws in the treatment of calcaneal fracture can significantly improve the condition of fracture,relieve pain,and improve the short-term quality of life of patients.
