Extracutaneous reduction and fixation device and reduction method for calcaneal fracture

Abstract

The invention provides an extracutaneous reduction fixation device and a reduction method for calcaneal fracture, comprising a bottom plate, a lateral plate and a medial plate. The outer surface of the outer plate and the inner surface of the inner plate are respectively provided with annular sliding paths, the annular sliding paths are provided with sliding blocks, the sliding blocks are also hinged with telescopic rods, and the free ends of the telescopic rods are provided with connection structures for connecting with bone screws or Swipes implanted in the calcaneus. The outer side plate comprises a restoring plate and a bone plate. The restoring plate is provided with an annular sliding path, the inner ring of the annular sliding path is provided with an annular through hole, and the bone plate is connected with the peripheral edge of the annular through hole. The bone plate is provided with a plurality of locking threads for penetrating the bone screw. The calcaneal fracture external reduction fixation device provided by the invention adjusts the bone screw or the Steinmann pin to the proper position by moving the length of the slider and the telescopic rod, reduces the calcaneal fracture, implants the locking screw through the suitable locking screw hole on the bone plate connected with the lateral plate after the fracture reduction is satisfactory, and percutaneous fixates the calcaneal fracture.

Description

technical field [0001] The invention belongs to the technical field of orthopedic medical appliances, and more specifically relates to an extracutaneous reduction and fixation device for calcaneus fractures and a reset method using the extracutaneous reduction and fixation device for calcaneus fractures. Background technique [0002] In real life, the calcaneus is a site that is prone to fractures. Since the calcaneus supports the weight of the human body, it is not easy to correct the fracture or dislocation of the calcaneus. [0003] At present, the treatment methods for displaced calcaneal fractures include manipulative reduction and plaster fixation, but this method cannot satisfactorily reduce the fracture, and cannot guarantee that the calcaneal fracture will no longer be displaced during the healing process. Therefore, resection of the calcaneal fracture is required. Open reduction, implant the bone plate, and then drill holes with an electric drill, and insert screws...
