The bio-absorbable bone tie with convex head is an elongated band having a convex head portion and is used for securing fragments of a fractured bone together. The elongated band portion includes a plurality of notches defined therein. The convex head portion has a convex shape with smooth, rounded edges and includes a channel or slot to receive a segment of the elongated band portion. At least one lock tooth extends into the channel or slot to engage the notches in the band and prevent the band from slipping back out of the channel, similar to a ratchet and pawl mechanism. The bone tie is constructed of a bio-absorbable material, such as polylactic acid. The leading end of the bone tie is the same color as the receiving opening of a corresponding inserter tool to minimize confusion when installing the bone tie with the inserter tool.
