Abstract

The invention discloses a tibia locking nail plate external fixator and a using method thereof. The tibia locking nail plate external fixator comprises a fixing plate and locking screws, wherein screwholes and threads are evenly formed in the fixing plate; the locking screws are installed in the screw holes, and the locking screws can be screwed into the screw holes for locking and fixing; the surface, directly facing and parallel to the front inner side of the tibia, of the fixing plate is an inner bottom arc surface; and the side surface, parallel to the front edge of the tibia, of the fixing plate is a peripheral arc surface consistent with the radian of the tibial axis. The external fixator has the advantages of serving as both an external fixator (external fracture fixation) and a locking bone fracture plate (internal fracture fixation), the tibia locking nail plate external fixator is used for treatment of a tibial distal fracture operation, closed reduction or minimally invasive incision reduction, the minimally invasive concept is embodied, the rapid rehabilitation surgery concept is embodied, and the fixator has high biomechanical stability through biomechanical measurement.

Description

technical field [0001] The invention relates to the medical field, in particular to a tibial locking nail plate external fixator and a using method thereof. Background technique [0002] Open tibial fractures are one of the common types of fractures in clinical practice. Internal fixation with steel plates is prone to complications such as poor wound healing, bone exposure, and infection. Therefore, external fixators play an important role here. The stability of the external fixation frame is poor, and it is easy to cause nonunion. In addition, the external fixation frame is bulky and heavy, which is inconvenient for daily life, hinders personal hygiene and dressing, and is prone to complications such as screw tract infection and loosening, especially near the tibia. For segmental or distal fractures, the fracture end close to the joint is very short, and the external fixator needle cannot be fixed in the metaphysis, and often needs to be fixed across the joint. Long-term fi...
