ABSTRACT

It explains the principle of dynamic osteosynthesis used by Küntscher on the design of his nail, the problem of rotational and longitudinal instability with this system is also discussed. The physical principles over which an intramedullar nail works are analyzed, as well as to which characteristics make it stable and where are its points of less resistance, making these the most vulnerable to failure risk. At the same time, the ways these malfunctions have been improved to create a more efficient system are also discussed.
