Abstract
A modular bone model can include a bone component and an implant component that can be positioned on the bone component. The implant component can be shaped and sized to correspond to a head component of a medical implant to simulate an articulating surface of the head component. Similarly, the bone component can be shaped to simulate a natural bone to which the medical implant can be mounted. Alternatively, the head component of the medical implant can be mounted directly to the bone component to simulate the mounting on the natural bone.
Claims19
A bone model for trialing a medical implant mountable on a natural bone to repair a natural articulating surface, comprising:
- a bone component shaped and sized to approximate at least a portion of the natural bone, the bone component comprising a physical bone model that is manufactured based on measurements obtained by imaging the natural bone;
- and
- a trial implant component shaped and sized to approximate at least a portion of the medical implant, the trial implant component including a trial articulating surface that approximates an articulating surface of the medical implant;
- wherein the trial implant component is positionable on the bone component to approximate mounting of the medical implant onto the natural bone;
- and
- wherein the bone component further includes a releasable locking feature engageable to the trial implant component for fixing the trial implant component on the bone component.
A bone model for trialing a medical implant mountable on a natural bone to repair a natural articulating surface, comprising:
- a bone component shaped and sized to approximate at least a portion of the natural bone, the bone component manufactured based on measurements obtained by imaging the natural bone;
- and
- a trial implant component shaped and sized to approximate at least a portion of the medical implant, the trial implant component including a trial articulating surface that approximates an articulating surface of the medical implant;
- wherein the trial implant component is positionable on the bone component to approximate mounting of the medical implant onto the natural bone;
- and
- wherein the bone component further includes a releasable locking feature engageable to the trial implant component for fixing the trial implant component on the bone component and at least one positioning feature for adjustably engaging the trial implant component to maintain the trial implant component on the bone component, wherein the positioning feature further includes a slide for slidably engaging the trial implant component such that the trial implant component can be slid on the at least one positioning feature to at least one offset position.
