Abstract:
1. A target jig instrument for use with an implantable prosthesis, the target jig instrument comprising: a. a handle having a superior end and an inferior end, the handle formed from a radio translucent material and having a target hole for guiding a bone drill, the target hole defining a target central axis; b. a nose component attached to the handle and removably connectable to the prosthesis, the nose component including a yoke portion and a shaft portion, the yoke portion including an alignment sight formed from a radioopaque material and including a pair of spaced-apart, opposing arms defining a U-shaped gap therebetween, the shaft portion defining a shaft portion central axis that extends into the U-shaped gap between the opposing arms, the shaft portion configured to selectively couple with the implantable prosthesis; and c. a tower extension assembly having a plurality of spaced-apart, parallel through-holes, the tower extension assembly having structure that selectively couples with opposing sides of the inferior end of the handle, the tower extension assembly having a pair of spaced apart posts that are selectively received by complementary holes defined in the target jig; whereby a first plane containing the target central axis bisects the U-shaped gap, such that a radioscopic image of the alignment sight showing the entire width of the U-shaped gap is a first visual reference to the user as to the direction of the target central axis.
