    • A woven retention device for interfacing with a bone surface includes interwoven filaments forming a tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. The protuberances are formed by intersecting interwoven filaments. The retention device receives and surrounds a fastener. In a first, relaxed state, the retention device has multiple combinations of filament cross-section geometries at the intersection points, and the multiple combinations of filament cross-section geometries form multiple protuberance thicknesses. In a second state when surrounding at least a portion of the fastener, the retention device distributes pressure from the fastener to multiple points of contact on the exterior surface of the retention device such that a spatial relationship of the protuberances changes as a function of bone density of the bone surface and as a function of an interfacing surface shape of the fastener.
    • 用于与骨表面接合的织造保持装置包括形成管状网格的交织的长丝,其中突起以预定的空间关系分布在网格的内部和外部表面上。 突起由交织的长丝交织形成。 保持装置接收并围绕紧固件。 在第一个松弛状态下,保持装置在交点处具有多个长丝截面几何形状的组合,并且细丝横截面几何形状的多重组合形成多个突起厚度。 在围绕紧固件的至少一部分的第二状态下,保持装置将压力从紧固件分配到保持装置的外表面上的多个接触点,使得突起的空间关系作为骨密度的函数而变化 的骨表面并且作为紧固件的接合表面形状的函数。
