Abstract
An intramedullary nail has a dynamization opening that accommodates and utilizes a dynamization window insert. The dynamization window insert is press-fit into the dynamization opening. The dynamization window insert is oval shaped and includes first and second protrusions that extend from respective surfaces of the dynamization window insert. The dynamization opening is sized to receive the dynamization window insert but compress the protrusions/window insert during insertion. The dynamization opening includes channels or grooves that are sized to accommodate the protrusions and allow the protrusions/window insert to return to an uncompressed state when situated therein. The dynamization opening and window insert cooperate to allow a press fit of the window insert into the dynamization opening with an elastic snap-fit and audible sound.
