Abstract
Implantable devices for the surgical treatment of bone, and particularly to a bone defect at a joint region, and even more particularly at the subchondral bone level of the joint region, are disclosed. The implantable devices may be formed of a bone material, and configured to serve the dual functions of providing mechanical strength and structural integrity to the area to be treated, while also facilitating the dispersal of a flowable material in the same area. Associated delivery tools are also provided.

9. A method of treating a bone defect, comprising the steps of:
-
providing an implantable device having a first, leading end, a second, trailing end, and a main body extending between the ends, a central opening extending through the length of the main body, and a channel in fluid communication with the central opening to allow extrusion of a flowable material from the central opening to outside the main body, the device being formed of allograft material; inserting the implantable device in or adjacent to the bone defect; introducing a flowable material through the central opening and out of the channel; and allowing the flowable material to extrude away from the device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
