Introduction. Heel bone fractures make up about 2% of all skeletal fractures and almost 60% of injuries to the metatarsal part of the foot. According to the statistics, more than 75% of fractures are intra-articular ones. Conservative treatment of intra-articular fractures of the heel bone has limited indications and is recommended as an alternative in the presence of contraindications to the surgical treatment. Because of high risks of postoperative complications, the number of studies devoted to minimally invasive surgical treatment techniques has been increasing in recent years. The purpose of this work is to conduct a comparative analysis of the effectiveness of treatment of intra-articular fractures of the calcaneus bone using minimally invasive techniques. Materials and methods. The treatment outcomes of 33 patients (38 fractures) were analyzed. Patients were divided into 2 groups: the 1 group included individuals who underwent closed repositioning and fixation with cancellous screws, the 2 group included individuals who received minimally invasive open reduction through access to the subtalar sinus and fixation with an angular stability plate. Results. Differences in pain syndrome assessment by a visual analogue scale, oedema of the operated segment and quality of wound healing testified in favour of transcutaneous fixation with screws. The quality of life according to The Lower Extremity Functional Scale was assessed as good in both groups in 3 and 6 months following the surgical operation. Functionality of the foot according to the Foot Function Index scale in 3 and 6 months was interpreted as "good" and "excellent" in both groups, respectively. Conclusion. Depending on the type of intra-articular fracture, both minimally invasive techniques of surgical treatment of complicated calcaneus fractures enable to restore anatomical reduction, prevent a significant number of complications, reduce pain, promote wound healing and achieving the formation of a cosmetic postoperative scar, as well as improve quality of life in the postoperative period. Minimally invasive osteosynthesis with cancellous screws has advantages over osteosynthesis with plates according to separate performance evaluation criteria, but its use is limited by the biomechanical characteristics of the injury.
