Abstract:
1. A bio-absorbable bone tie with convex head, comprising: an elongated, flat, flexible band having a front side, a rear side, a leading end and a trailing end, the front side having a plurality of notches defined therein; a spoon-shaped head portion having a pair of smooth, rounded lateral edges, a front side having a concave shape, and a back side having a convex shape disposed between said lateral edges, the head being integral with and extending from the trailing end of said band, said head portion defining a channel having an entrance substantially centrally disposed in said concave shaped front side, and an exit substantially centrally disposed in said convex shaped back side, said channel extending through said head portion from the front side to the back side, the channel being dimensioned for reception of said band; and a lock member disposed within said channel having at least one lock tooth configured to interlock the notches defined in the front side of said band, thereby securing said band around bone fragments of a fractured bone when the leading end of said band is fed into the entrance of the channel in said head portion, said band, said head portion, and said lock member being formed in one piece from a bio-absorbable material; wherein said leading end of said band is fed through said channel from said front side of said head portion, upon tensioning said band around a fragmented bone said locking member preventing said band from reversing from said channel, said head portion is firmly secured against a surface of the fragmented bone; whereby said head portion forms a smooth rounded surface adjacent the fragmented bone, preventing any damage to tissue surrounding the fragmented bone.
