Objective  To compare the effect of transtarsal sinus incision internal fixation and translateral L-shaped incision plate internal fixation in the treatment of patients with Sanders Ⅱ to Ⅲcalcaneal fractures.

  Methods  A total of 80 patients with Sanders Ⅱto Ⅲcalcaneal fractures were selected and randomly divided into treatment group A and treatment group B. Treatment group A was treated with classical translateral L-shaped incision plate internal fixation, while treatment group B was treated with transtarsal sinus incision internal fixation by hollow nail. Surgical effect was compared between two groups.

  Results  The bleeding volume and drainage volume in treatment group B were significantly lower than those in treatment group A (P < 0.05). The calcaneal Bohler angle and Cissane angle in both groups were significantly higher than those before operation (P < 0.05), but there were no significant differences in the calcaneal Bohler angle and Cissane angle between the two groups before and after operation (P>0.05). The incidence rate of total complications in treatment group B was significantly lower than that in treatment group A (P < 0.05), and there were no significant differences in Maryfand score, excellent and good rate between the two groups at 12 months after operation (P>0.05).

  Conclusion  Classical translateral L-shaped incision internal fixation is similar to transtarsal sinus incision internal fixation in the treatment of Sanders Ⅱ to Ⅲcalcaneal fractures, but transtarsal sinus incision internal fixation has the advantages of less bleeding, less drainage volume and fewer complications.
