US Classification:

623 1611, 623 2014, 623 2358, 623908

Abstract:

A method for treating arthritis of a joint includes identifying a bone lesion in a bone adjacent to the joint; and implanting in the bone a reinforcing member in or adjacent to the bone lesion. A kit for conducting the method includes: (a) at least one reinforcing member having a proximal face adapted to face the joint, a distal face adapted to face away from the joint, and a wedge-shaped edge adapted to pierce bone, wherein the at least one reinforcing member is planar and sterile; and (b) a container adapted to maintain the at least one reinforcing member sterile. Another kit includes: (a) a sterile fluid; (b) a syringe for injecting the fluid into a bone; (c) a curing agent adapted to cure the fluid to polymerize and/or cross-link; and (d) a container adapted to maintain the sterility of contents of the container.

International Classification:

A61F 2/28

US Classification:

623 1611, 606 62

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.

International Classification:

A61F 2/44

US Classification:

623 1711, 606279

Abstract:

Methods for altering the natural history of degenerative disc disease and osteoarthritis of the spine are proposed. The methods focus on the prevention, or delayed onset or progression of, subchondral defects such as bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis or degenerative disc disease in the spine and thereby treat pain.

International Classification:

A61B 17/58

US Classification:

606 92, 606 93, 606 86 R

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.

US Classification:

606 92, 600410, 606 86 R, 623 1611

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.

US Classification:

606 96, 606 86 R

Abstract:

Instruments and associated methods are disclosed for treating joints, and particularly bone tissue. One of these instruments may be a positioning instrument for controlled delivery of a device to a target site of the bone tissue being treated. The positioning instrument may comprise an alignment guide having a device portal for insertion of a device therethrough. The positioning instrument may have an indicator probe having an extended arm, and a handle portion for maneuvering the positioning instrument. Another instrument may be a device for placement through the device portal of the alignment guide and to the target site. The device may comprise an implant insertion tool, an injection catheter, a cavity creation tool such as a bone drill, for example, or the device may be an implantable device.
