  • Publication number: 20190133663
    Abstract: The embodiments provide provides devices, instruments, and associated methods for treating joint pain. A joint is evaluated using magnetic resonance imaging to detect any defects in the subchondral bone. For example, using T2-weighted MRI images, bone marrow lesions or edemas can be identified, and using T1-weighted MRI images, associated regions of sclerotic bone adjacent to the bone marrow lesion can be identified. The treatment method may involve introducing a bone void filler material at the site to address the bone marrow lesion or edema, and/or drilling and inserting an implant to address the sclerotic bone, bone marrow lesion or edema, and insufficiency or stress fractures. An access path is mapped to a location in the subchondral region where the insufficiency fracture resides. The access path attempts to preserve an articular surface of the joint. A reinforcing member that stabilizes the insufficiency fracture is then implanted via the access path.

  • Patent number: 9717544
    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.

  • Patent number: 9539042
    Abstract: A syringe configured to deliver viscous compositions is described, in which the syringe may include an elongate chamber having side port(s) extending therefrom. Various viscous compositions may be inserted through the side port(s) and into the elongate chamber, which may further house a plunger for ejecting the composition. One portion of the plunger may interact with a restricted opening on the chamber to inhibit removal of the plunger from the chamber; and another portion of the plunger may have a locking structure, which cooperates with a locking structure on the chamber to selectively fix the plunger with respect to the chamber. The plunger may also be fully slidable within the chamber when the locking structures of the plunger and the elongate chamber are not engaged. Related methods of using the aforementioned syringe, as well as kits including further instruments that interact with the syringe, are also disclosed.
