Abstract

Apparatus and methods for treatment of a bone. The apparatus may include an implant. The implant may include an implant tail and an implant head configured to expand, inside the bone, from a collapsed state to an expanded state. The apparatus may include an intramedullary rod defining a central longitudinal rod axis. The intramedullary rod may include a guide segment configured to guide the implant head into the bone and support the implant tail. The intramedullary rod may include an elongated extension member spaced radially apart from the central longitudinal axis. The extension member may be configured to provide clearance for the implant head as the implant head is advanced, in the collapsed state, into the bone. The extension member may be configured to provide clearance for the implant head in the expanded state.
