Abstract
An expandable augment system is provided for use with an acetabular cup. The expandable augment system can include an expandable augment module that is adjustable in size and that can be adjusted incrementally between a fully collapsed state and an expanded state. A first portion of the expandable augment module is attachable to an outer surface of an acetabular cup and a second portion of the expandable augment module is attachable to bone or to a fixed augment module (e.g., a fixed angle augment module) that is attached to bone and interposed between the adjustable augment module and bone.

An expandable augment module for an acetabular cup, comprising:
- a first plate configured to couple with a bone or a fixed augment module, the first plate having a convex first surface and a concave second surface opposite the convex first surface;
- and
- a second plate configured to pivot relative to the first plate between a first position where the second plate is proximate the first plate along its length and a second position where at least a portion of the second plate is spaced from the first plate, the second plate having a convex third surface and a concave fourth surface opposite the convex third surface, the convex third surface configured to face the concave second surface when the expandable augment module is in a collapsed position, the concave fourth surface configured to couple to an outer surface of an acetabular cup.
An expandable augment module for an acetabular cup, comprising:
- a first plate configured to couple with a bone or a fixed augment module, the first plate being curved in a widthwise direction and a lengthwise direction;
- and
- a second plate attached to the first plate and configured to pivot relative to the first plate between a first position where the second plate is proximate the first plate along its length and a second position where at least a portion of the second plate is spaced from the first plate, the second plate being curved in a widthwise direction and a lengthwise direction.
