Abstract

The present invention discloses an electrical insulator that is applied to a bone anchor, such as an external fixation frame, such as a bone implant, to prevent undesired temperatures in the bone anchor and surrounding anatomical tissue when subjected to magnetic resonance imaging Increase.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority to US Patent Application Serial No. 13 / 837,598 filed March 15, 2013, the disclosure of which is hereby incorporated by reference as if set forth in its entirety herein. Background technique [0003] Bone fixation systems may include external bone fixation systems, which are typically attached to two or more bone components in order to stabilize the bone components and promote healing. External bone fixation systems can be used in the treatment of comminuted, intra-articular and / or unstable fractures. Thus, the bone component may be a fractured bone segment, or may alternatively be two different bones that are stabilized relative to each other, such as a vertebra. A typical external fixation system may include a plurality of bone anchors configured to be driven across the epidermal surface and into corresponding bone components. For example, bone anchors are typically configured a...
