An implant including a substantially cohesive aggregate comprising bone-derived particles. Cohesiveness is maintained by a member of mechanical interlocking, engagement of adjacent bone-derived particles with one another through engagement with a binding agent, thermal bonding, chemical bonding, or a matrix material in which the bone-derived particles are retained. The aggregate is shaped as a one-dimensional or two-dimensional body.
