Sanders Ⅱ and Ⅲ intra-articular calcaneal fractures primarily result from falls from height, often accompanied by severe flap soft tissue injury and notable displacement of fracture fragments, which can pose significant reconstruction challenges. The traditional "L" lateral incision open reduction and internal fixation technique is considered the gold standard for the surgical treatment of calcaneal fractures. This trial aims to demonstrate that Percutaneous Cannulated Screws are not inferior to open reduction and internal fixation (ORIF) with plates in the treatment of calcaneal fractures.
