Tibial intramedullary nails for fractures periarticular

摘要

The invention relates to trauma, namely the intramedullary nail with locking, and is designed for osteosynthesis high periarticular fractures of the tibia. The tibial nail is a rod of titanium alloy having a proximal end, joins the handle-conductor and a rounded distal end. At the proximal end is provided with two circular openings and below them - one oval hole. Two circular holes are formed at an angle of 45 degrees to the plane of the front and 90 degrees to each other at different levels. The screws holes are administered: in round holes (static) and at both edges of the oval holes (static or dynamic). The proximal flexure rod is formed as close to the end of the nail (50-60 mm) close to an oval hole, it allows to stably fix the fragments at fractures of the upper third tibia. Static screws are introduced in 45-degree opening and the lower edge of the oval. Dynamic - on the upper edge of the oval. At the distal end of the nail formed an oval hole in the frontal plane, and circular openings in the anterior-posterior and frontal planes to stabilize the distal fractures. The achieved effect - ensuring the quality of matching fragments fixation and stability at high periarticular fractures of the tibia; higher fatigue resistance of the nail; expanding the possibility of applying high fractures, due to the possibility of convergence fragments axis after dormant.
