1. A method of treating a bone defect, comprising:
- providing or obtaining a first implantable device for insertion into bone, the first implantable device comprising an elongate body extending between a first, leading end and a second, trailing end, the second end including a tool-receiving portion for receiving a tool, the elongate body including a central canal for receiving a flowable material, and having one or more channels in fluid communication with the central canal, the channels being located along one side of the elongate body;
providing or obtaining a second implantable device for insertion into bone, the second implantable device comprising an elongate body extending between a first, leading end and a second, trailing end, the second end including a tool-receiving portion for receiving a tool, the elongate body including a central canal for receiving a flowable material, and having one or more channels in fluid communication with the central canal, the channels being located along one side of the elongate body;
implanting the first and second implantable devices into a subchondral level of a bone, in a spaced apart and generally parallel configuration, such that the one or more channels of each device are oriented towards each other; and
injecting a flowable material into at least one of the implantable devices.

Abstract
Devices and associated methods are disclosed for treating bone, and particularly bone tissue at the joints. Disclosed are implantable devices that can be used either alone or in combination with this augmentation or hardening material for the repair of bone defects and which are particularly suited for use at the joints, and even more particularly suited for use at the subchondral bone level.

13. A method of treating a subchondral bone defect of a bone, comprising:
-
providing or obtaining an implantable device for insertion into bone, the implantable device comprising an elongate body defining an outer surface and extending between a first, leading end and a second, trailing end, the second end including a tool-receiving portion for receiving a tool, the elongate body including a central canal for receiving a flowable material, and having one or more channels in fluid communication with the central canal, the channels being located along one side of the elongate body, wherein the elongate body further includes a depressed, cutaway portion extending into the outer surface of the elongate body, the depressed, cutaway portion sized and shaped for containing the area where flowable material is dispersed, the one or more channels residing within the depressed, cutaway portion; implanting the implantable device into a subchondral level of the bone, while preserving an articular surface of the bone, such that the one or more channels are directed toward the subchondral bone defect; and injecting a flowable material into the implantable device, wherein the flowable material is dispersed in a directionally controlled manner to the subchondral bone defect for treatment of the defect. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A method of treating a bone defect, comprising:
-
providing or obtaining a first implantable device for insertion into bone, the first implantable device comprising an elongate body extending between a first, leading end and a second, trailing end, the second end including a tool-receiving portion for receiving a tool, the elongate body including a central canal for receiving a flowable material, and having one or more channels in fluid communication with the central canal, the channels being located along one side of the elongate body; providing or obtaining a second implantable device for insertion into bone, the second implantable device comprising an elongate body extending between a first, leading end and a second, trailing end, the second end including a tool-receiving portion for receiving a tool, the elongate body including a central canal for receiving a flowable material, and having one or more channels in fluid communication with the central canal, the channels being located along one side of the elongate body, wherein the elongate bodies of the first and second implantable devices each include a depressed, cutaway portion for containing the area where the flowable material can extrude, the one or more channels residing within the depressed, cutaway portion; implanting the first and second implantable devices into a subchondral level of a bone such that the one or more channels of each device are oriented towards each other; and injecting a flowable material into at least one of the implantable devices.
