ObjectiveTo investigate the effect of mini-incision open reduction and full-thread cannulated screw internal fixation on calcaneous fracture. MethodsA total of 105 patients with calcaneous fracture were selected as research objects and divided into experimental group (n=53) and control group (n=52) by the random number table method. The control group was treated with lateral L-shaped incision plate internal fixation, while the experimental group was treated with mini-incision open reduction and full-thread cannulated screw internal fixation. The clinical efficacy, operation condition, calcaneous tubercle joint angle (angle of Bhler), calcaneous intersection angle (Gissane angle), fracture healing time, foot function score and incidence of complications were compared between the two groups. ResultsThe operation time, intraoperative blood loss, hospital stay, incision length and postoperative drainage volume of experimental group were all less/shorter than those of control group (all P＜0.05). At the 6th month after operation, the clinical efficacy of the experimental group was better than that of the control group, the Gissane angle was larger than that of the control group, fracture healing time was shorter than that of the control group, foot function score was higher than that of the control group, and the total incidence of complications was lower than that of the control group (all P＜0.05). ConclusionThe application of mini-incision open reduction and full-thread cannulated screw internal fixation has significant effect on patients with calcaneous fracture, which can shorten fracture healing time and improve the foot function with few complications.
