ABSTRACT:
An orthopedic implant device is provided for bringing portions of a fractured bone into proper alignment and abutment. The device is an elongate generally cylindrical unit surgically implanted within living bone with a fractured portion and includes a plurality of pivotally mounted struts which are deployed within the cancellous material of the bone distant from said fractured portion thereof. The struts are pivotally deployed radially outwardly until anchoring contact with the interior surface of the surrounding cortex of the distant portion of the fractured bone is established. The components of the device maintain a force urging the portions of the bone defining the fracture toward each other. When the device is to be removed from the bone, the struts can be collapsed so that the device can be withdrawn. Should regrowth of bone and the anchoring interaction between the struts and the bone prevent the struts from collapsing, the struts can be severed from the device and withdrawn by elongate flexible connectors which are connected with and extend between the struts and the remaining structure of the device.
