Subchondral treatment of joint pain
First Claim
1. A system for treating joint pain comprising:
- an injectable material for biological stimulation of a healing response to a subchondral defect in a subchondral region of a bone adjacent to the joint;
an injector tool for delivery of the material; and
an instrument for guiding the injector tool, the instrument comprising a guide portion including a plurality of portals configured to guide the injector tool toward the subchondral region for treating the subchondral defect, the guide portion having a reference tip.

Abstract
The embodiments provide devices and methods that both strengthen the bone and stimulate the bone. Bone fractures or non-unions are stabilized, integrated or healed, which results in reduction of a bone defect, such as a bone marrow lesion or edema. In addition, the distribution of forces in a joint are restored or altered to relieve pain. In general, a joint is evaluated by taking an image of the joint and one or more subchondral defects are detected. At least one of the subchondral defects may be diagnosed as the source of pain and an extent of treatment for the subchondral defect is determined. The disclosed devices and techniques are particularly suited for treating chronic defects or injuries, where the patient'"'"'s natural healing response has not resolved the defect. The present disclosure also provides several exemplary treatment modalities for the different extents of treatment needed.
