Description
Technical Field
The utility model relates to the technical field of medical appliances, especially, relate to improved generation calcaneus anterior process anatomical plate.
Background
Currently, the calcaneus is the main weight bearing bone of the human body, meanwhile, the calcaneus is also the largest cancellous bone in the tarsal bones of the human body, and the fracture of the calcaneus is the most common fracture of the tarsal bones. In the treatment of calcaneal fractures, it is not negligible that accurate reduction and strong fixation are necessary to load the patient as early as possible and functional recovery is necessary, and the fracture of the root bone accounts for 2% of the total fracture and 60% of all tarsal bones. The injury of the root bone can lead to serious disability, the high-energy fracture of the root bone can be suffered from most patients of the fracture in addition to change lives, in the process of treating the calcaneus fracture, the incision reduction internal fixation treatment is recommended, the fracture nonunion or the malformation union can be avoided after the internal fixation, the postoperative complications can be reduced, a novel product is introduced, and the calcaneus minimally invasive locking plate is related to, namely, the fracture part of the calcaneus is fixed and reduced, and the union of the fracture end and the normal activity of the heel part are ensured. At present, three methods are adopted for treating calcaneal fracture generally, namely conservative treatment and plaster fixation, the fixation cost is low, the wound is small, but the fracture end is easy to displace again, the treatment period is long, the healing is slow, and the probability of fracture nonunion and deformity healing is high; secondly, percutaneous needle threading fixation or open reduction kirschner wire or screw fixation is adopted for reduction by a manipulation, the fixation is stable, the secondary displacement is not easy, but the rotary displacement is easy to occur, the fracture healing is influenced, the deformed healing is easy to cause, and even the needle or screw breaking condition occurs in serious cases; thirdly, the calcaneus is fixed by adopting a calcaneus dissection plate, the fixation is suitable for calcaneus comminuted fracture, the wound is large, and the necrosis of the outer skin flap of the calcaneus, the nerve injury and the like are easily caused. The minimally invasive calcaneus plate adopts tarsal sinus approach, has small wound and stable joint surface fixation, and greatly reduces the risk of flap necrosis, so an improved anterior calcaneus dissection plate is urgently needed to solve the problems.
