Abstract
This disclosure relates to orthopaedic implant systems and methods for repairing bone defects and restoring functionality to a joint. The implant systems and methods disclosed herein may include augments extending from respective baseplates. The augments may have an internal network for communicating material in the respective implant.
Core Innovation
The invention relates to an orthopaedic implant system for repairing a bone by using an implant including a baseplate and an augment. The baseplate has a plate body extending between front and rear faces, where the front face is configured to face towards an opposed articular surface associated with a bone. The augment includes an augment body extending from the rear face of the plate body.
The augment body includes a network of internal passages that branch to respective ports along an external surface of the augment body. The implant includes an interface aperture defined along an external surface of the implant, and the network includes a main trunk. The internal passages divide from the main trunk into branched paths at respective junctions such that at least two of the junctions are established between the interface aperture and each of the respective ports, thereby coupling the interface aperture to the ports through branched internal pathways.
The implant further includes at least one fixation aperture configured to receive a respective fastener to secure the implant to bone, where the fixation aperture includes a first section extending through the plate body and a second section extending through the augment body. In certain configurations, the implant includes a pump configured to draw biological material at least partially into the network, and the augment may also include one or more bioactive layers on surfaces that define the network.
Claims Coverage
Two independent claims are present in the provided material. Together they cover a baseplate and augment system with a branching internal passage network from an interface aperture to external ports, fixation apertures that extend through both the plate body and the augment body, and an embodiment that further includes a pump configured to draw biological material into the network.
Baseplate and rearward augment with branched internal passage network to external ports
An implant including a baseplate and an augment, where the baseplate includes a plate body extending between front and rear faces configured so the front face faces towards an opposed articular surface associated with a bone, and where the augment includes an augment body extending from the rear face of the plate body, the augment body including a network of internal passages that branch to respective ports along an external surface.
Interface aperture coupled to ports through main trunk and junctions
The implant includes an interface aperture defined along an external surface of the implant, and the network includes a main trunk in which internal passages divide from the main trunk into branched paths at respective junctions such that at least two of the junctions are established between the interface aperture and each of the respective ports.
Fixation apertures extending through plate body and augment body
The implant includes at least one fixation aperture configured to receive a respective fastener to secure the implant to bone, where the at least one fixation aperture includes a first section extending through the plate body and a second section extending through the augment body.
Pump drawing biological material into the internal passage network
A pump configured to draw biological material at least partially into the network, where the implant includes a baseplate and an augment extending from the baseplate and the baseplate front face is configured to face towards an opposed articular surface associated with a bone, with the augment including a network of internal passages coupled to respective ports along an external surface.
Across the independent claims, the core claim coverage is the combination of a baseplate and augment with a network of internal passages branching to external ports, an interface aperture with junction-defined connectivity between the interface aperture and ports, and fixation apertures that extend through both the plate body and augment body. One independent claim additionally requires a pump configured to draw biological material at least partially into the network.
