Study on the therapeutic effect of reduction by leverage combined with minimally invasive plate placement in the treatment of patients with Sanders type II and III calcaneal fractures

Objective: To study the therapeutic effect of reduction by leverage combined with minimally invasive plate placement in the treatment of patients with Sanders type II and III calcaneal fractures. Methods: A total of 80 patients with Sanders type II and III calcaneal fractures were selected and divided into the study group and control group according to a random number table, with 40 cases in each group. Patients in the study group were treated with reduction by leverage combined with minimally invasive plate placement, while those in the control group were treated with an L-shaped incision. The Bohler angle, Gissane angle, calcaneal width and pain score in both groups were measured before and after treatment. The related indexes of operation and hospitalization, excellent and good rate of foot function recovery and incidence of complications were compared. Results: The Bohler angle and pain score in both groups one month after operation were higher than those before operation, while the Gissane angle and calcaneal width were lower than those before operation (all P<0.01). The Bohler angle and pain score in the study group one month after operation were higher than those in the control group, while the Gissane angle and calcaneal width in the study group one month after operation were lower than those in the control group (P<0.05 or P<0.01). The bleeding volume and treatment costs in the study group were less than those in the control group, the incision length, hospital stay and fracture healing time were shorter in the study group, and the operation time was longer in the study group (P<0.05 or P<0.01). The excellent and good rate of foot function recovery in the study group was higher than that in the control group, while the incidence of complications was lower than that in the control group (all P<0.05). Conclusion: Reduction by leverage combined with minimally invasive plate placement had significant therapeutic effects on the treatment of patients with Sanders type II and III calcaneal fractures. This method had less trauma for the patient, shortened the hospital stay, relieved pain, it also promoted the reposition and recovery of foot function and reduced complications.
