【Abstract】 ObjectiveTo investigate the efficacy and safety of miniincision and Lshaped incision in the treatment of calcaneal fracture. MethodsOf 64 patients with calcaneal fracture, 34 patients receiving treatment with minimally invasive incision were enrolled as observation group, and 30 patients with traditional Lshaped incision as control group. The operation duration, intraoperative blood loss, the length of incision, duration for stitches removal, the recovery degrees of Bohler and Gissane angles, longterm function score and incidence of complications were compared between the two groups. ResultsThe operation duration of the observation group was shorter than that of the control group ［ (69.7±9.4) min vs.(86.2±10.3) min, P＜0.05］.The intraoperative blood loss, the length of incision, duration for stitches removal in the observation group［ (124.6±12.4) mL, (4.8±1.2) cm and (12.1±1.8) d, respectively］ were less or shorter than those in the control group［(260.4±34.7) mL, (13.2±2.6) cm and (14.6±2.3) d, respectively］(P＜0.05). There were no significant differences in Bohler and Gissane angles between the observation group ［（28.6±8.4）° and （119.5±5.1）° respectively］ and the control group ［（29.4±6.8）° and （117.6±6.2）° respectively, P＞0.05］。The AOFAS score of the observation group was higher than the score of the control group ［（87.5±8.1）vs（73.5±7.6），P＜0.05］. The incident rate of the observation group was lower than that of the control group［2.4%（1/34）vs 12.7%（4/30），P＜0.05］。ConclusionMinimally invasive incision is safe and effective in the treatment of calcaneal fractures. It is worthy to be clinical widely romotion.
