The bio-absorbable bone tie (10) with convex head is an elongated band having a convex head portion (40) and is used for securing fragments of a fractured bone together. The elongated band portion (20) includes a plurality of notches (30). The convex head portion (40) has a convex shape with smooth, rounded edges and includes a channel or slot (52) to receive a segment of the elongated band portion (20). At least one lock tooth extends into the channel or slot (52) to engage the notches (30) in the band and prevent the band from slipping back out of the channel (52), similar to a ratchet and pawl mechanism. The bone tie (10) is constructed of a bio-absorbable material, such as polylactic acid. The leading end (28) of the bone tie (10) is the same color as the receiving opening of a corresponding inserter tool to minimize confusion when installing the borne tie with the inserter tool. |
