Analysis of the Curative Effect of Metatarsal Sinus Incision and "L"-shaped Incision in the Treatment of Calcaneal Fractures

Objective To compare the clinical efficacy of sinus tarsi incision and traditional operation in the treatment of calcaneal fractures. Methods A total of 46 patients with calcaneal fracture admitted to Jianli People's Hospital from June 2020 to January 2022 were included, including 37 males and 9 females. 23 patients in the control group were treated with "L" incision, and 23 patients in the experimental group were treated with tarsal sinus incision. The length of hospitalization, operation time an, surgical incision length, grainage volume, complication of the two groups were recorded respectively. The results of Bohler Angle and Gissane Angle were measured before and after operation. Results The operation time of the test group is shorter than that of the control group. Compared with the operation time of the two groups, the difference is statistically significant (P<0.01). The postoperative drainage flow of the test group is less than that of the control group. The contrast difference between the two groups in the operation area is statistically significant (P<0.01), and the length of the surgical incision in the test group is shorter than that of the control group. The length of the surgical incision is statistically significant compared with the length of the two groups (P<0.01). The number of days of hospitalization in the test group is shorter than the number of days in the control group, but there is no statistical significance (P>0.05). The patient's pre-operative Bohler angle measurement result and the Gissane angle measurement knot. The difference has no statistical significance (P>0.05). Bohler Angle in both control group and experimental group was significantly higher after surgery than before surgery (P < 0.01), and Gissane Angle was significantly lower after surgery than before surgery (P < 0.01). However, there was no significant difference in Bohler Angle and Gissane Angle between the two groups before and after surgery (P > 0.05). The complication rate of control group was higher than that of experimental group, but there was no significant difference between the two groups (χ2=0.357, P > 0.05). Conclusion For Sanders II and III calcaneal fractures, the "L" incision is like the sinus tarsi incision. However, the incision of tarsal sinus has the advantages of small trauma, short operation time and good recovery of patients.
