Surgical management of calcaneal fractures has various complications. In recent years, minimally invasive surgeries have been utilized for a wide range of surgical procedures on different body parts significantly declining complications. This paper compares surgical outcomes of calcaneal fracture management between the open reduction and internal fixation technique (ORIF) and the MIS technique. In this randomized clinical trial forty patients with calcaneus fractures were randomly assigned to two equal groups; ORIF group and MIS group. Patients were followed for 1 year post-operatively. Gissane and Bohler’s angles, AOFAS questionnaire, pain intensity, ability to conduct previous activities and various complications like wound healing complications and irritation with shoe wear were assessed in the final post-operative visit. Eventually data obtained from the two groups were compared. All patients obtained fracture union. Bohler’s and Gissane angles significantly increased and decreased, respectively, after the operation in both groups (p<0.05), however, no significant difference was found between the two research groups. AOFAS scores and pain intensity was similar in both groups, however, surgical duration in the MIS group was significantly less than the ORIF group (P=0.021). Only one patient from the ORIF group was not able to resume his previous occupation. 12 patients from the ORIF group and five patients from the MIS group experienced irritation from shoe wear (p=0.025). In the ORIF group, 4 patients suffered from wound healing complications, however, none of the patients of the MIS group had wound complications (p=0.035). In conclusion, based on the results, it can be concluded that the MIS technique demonstrated better functional and radiographic outcomes as well as a more favorable complication profile, thus, it is recommended for the management of calcaneus fractures.
