Embodiment Construction

[0034] The present disclosure provides a method, device and instrument for diagnosing and treating joint pain to restore natural joint function and preserve the joint and cartilage surface of the joint as much as possible. Treatments through joints that interfere with joints and cartilage surfaces often weaken the bones and have unpredictable consequences. Instead of focusing on the treatment of pain through the joint, the embodiment diagnoses and treats the pain at its source in the subchondral region of the joint bone to relieve the pain. The applicant found that the pain associated with joints, especially osteoarthritis joints, can be related to bone defects or changes at the subchondral level, rather than, for example, the development of osteoarthritis or the severity of the defect in the surface layer of the joint . In particular, bone defects near the joint surface, such as bone marrow lesions, edema, cracks, fractures, bone sclerosis, etc., lead to mechanical disadvanta...

Abstract

An instrument for controlled delivery of a device to a target area near a defect of a bone is provided. The instrument comprises a guide frame having a plurality of device portals, each portal defining a trajectory. The guide frame further includes visual markers for aligning the guide frame to an anatomical landmark on the bone to be treated. The instrument also includes a holder for releasable attachment with the guide frame. Each device portal is configured to provide accurate and controlled delivery of the device to the target area. In one example, the markers are radiopaque, and are visualized through fluoroscopy. A method of using the instrument is also provided.

Description

Technical field [0001] The present invention relates to tools for surgical treatment of joints, in particular, to surgical repair and treatment of bone tissues at these joints, instruments and related methods. More specifically, the present invention relates to a navigation and positioning instrument for using anatomical landmarks to find and locate a device in an area near a bone defect. Background technique [0002] Human joints, especially knees, hips, and spine, are prone to decline due to diseases, trauma, and long-term repeated use that ultimately cause pain. For example, knee pain causes a lot of medical and related medical expenses. The most popular theory from the medical community is that knee pain is caused by contact between bones or insufficient cushioning of cartilage. These conditions are believed to frequently result from the development of osteoarthritis, which is measured by the narrowing of the joint space. Therefore, the severity of osteoarthritis is consid...
