Abstract
The present disclosure relates to flexible porous implant fixation systems. Certain aspects provide flexible porous structures including a helicoidal structure and a plurality of interlocking elements coupled to the helicoidal structure, the helicoidal structure being configured to connect the plurality of interlocking elements. Certain aspects provide a body comprising a porous structure, the body configured to interface with a bone perpendicular to an axis of the bone; and a screw comprising a head, wherein the head is configured to lie within a volume of the body while a portion of the screw extends away from the body, wherein the body is configured to restrict movement of the head within the body along the axis of the bone.
Claims21
A flexible porous structure configured for implantation into bone, the flexible porous structure comprising:
- a plurality of unit bodies;
- an outer skin configured to flexibly connect the plurality of unit bodies;
- and
- a plurality of interlocking elements,
- wherein:
- the plurality of unit bodies comprises a pair of adjacent unit bodies, the pair of adjacent unit bodies comprising a first unit body and a second unit body;
