摘要:
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.
