Abstract: Calcaneal fractures are the most common fractures of the foot,and approximately 75% are intra-articular injuries involving the subtalar joint.Compared with traditional open surgery,percutaneous minimally invasive treatment has shown several clinical advantages,including reduced soft-tissue trauma,a lower risk of wound-related complications,and faster postoperative recovery.From a practical clinical perspective,this article summarizes the key technical aspects of percutaneous minimally invasive treatment for calcaneal fractures,with particular attention to preoperative imaging evaluation and surgical planning,reduction strategies,selection of internal fixation,and postoperative management.In addition,it reviews the major challenges associated with this technique in current practice,including the difficulty of achieving anatomical reduction under limited visualization,radiation exposure related to repeated intraoperative fluoroscopy,and the relatively demanding learning curve for surgeons.On this basis,the article further outlines several targeted quality-control measures that may improve the consistency and safety of treatment,including precise preoperative assessment,standardized intraoperative procedures,and systematic postoperative follow-up and evaluation.Establishing a relatively complete quality control process may help improve surgical quality,reduce complications,and optimize patient outcomes.This article aims to provide a practical reference for clinicians and to support the standardized clinical application of this technique.
