Surgical fastener assembly
First Claim
1. A surgical fastener assembly for coupling first and second bone portions across a fracture therebetween, comprisingan anchor, said anchor including a first externally threaded portion adapted to be disposed in the first bone portion and a second portion which is adapted to be at least partially disposed in the second bone portion;
- at least one pin operably associated with said first portion of said anchor, wherein when said pin is in a retracted position said pin is disposed within said anchor and wherein when said pin is in an extended position at least a portion of said pin extends outward from said anchor;
an actuator, said actuator disposed within said anchor and operably coupled with said at least one pin;
a guide, said guide adapted to be fixedly secured to the second bone portion and including a sleeve, said second portion of said anchor received within said sleeve; and

Abstract
A surgical fastener assembly for coupling first and second bone portions across a fracture therebetween is disclosed. In one embodiment of the present invention, the surgical fastener assembly includes an anchor that has a first externally threaded portion disposed in the first bone portion and a second portion which is at least partially disposed in the second bone portion. At least one pin is operably associated with the first portion of the anchor such that when the pin is in a retracted position the pin is disposed within the anchor and when the pin is in an extended position at least a portion of the pin extends outward from the anchor. An actuator is disposed within the anchor and is operably coupled with the at least one pin. A guide is adapted to be fixedly secured to the second bone portion and includes a sleeve. The second portion of the anchor is received within the sleeve. A fastener is provided that has a head portion and an externally threaded shank portion. The shank portion threadedly engages with the anchor and the head portion operably engages with the guide.
