Curved Intramedullary Needle (Ender Needle) Internal Fixation

The curved intramedullary needle, also known as the ender needle, is a type of intramedullary needle. Its advantages are: the use of multiple curved intramedullary needles with a certain elasticity and hardness is inserted into the medullary cavity, reaching the neck of the femur, and spreading in a fan shape. Can effectively control the movement of the fracture end. Especially for the elderly, because the affected limb can move early and shorten the bed time, thereby reducing systemic complications; the use of curved intramedullary needle internal fixation, short operation time, less blood loss, less trauma, incision away from the fracture site, so infection The risk is less than other internal fixation methods. The disadvantage is that the multiple arcs are still insufficient to control the rotation of the fracture end. Especially for patients with severe osteoporosis, the fixation is often not strong. At the same time, early and late complications can not be ignored.
