Abstract

See full text

The agraffe is composed of a deformable metal plate having two projections, each of which is provided with a threaded eyelet. In addition, anchored pins are threaded into the respective eyelets and can be selected from a set of pins having different lengths. The deformable plate is arched between the projections and has a plurality of tacks fixably secured in place to increase adhesion of a ligament or tendon to a bone. The instrument for implanting or extracting the agraffe includes a pair of angular sector-shaped grooves of T-shaped cross-sections which are sized to engage with and under the heads of the pins in order to form a connection between the instrument and agraffe.
