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.
Claims20
An implantable device for treatment of a bone defect, comprising:
- 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 bone material.
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.
An implantable device for treatment of a bone defect, comprising:
- a first, leading end, a second, trailing end, a main body extending between the ends, and at least one recess extending down at least a portion of the main body, the device being formed of a bone material.
