System and technique for accessing extra articular lesions or abnormalities or intra osseous lesions or bone marrow lesions

Abstract

A system for accessing lesions or abnormalities using intra articular localization, the system has a first arm with a localizing pin at a first end for defining a virtual pathway and a guide component. The guide component has a straight guide portion and a curved guide or arcuate portion. The curved guide or arcuate portion defines a second arm having a plurality of angularly spaced guide notches for locating a movable guide configured for passing a pin or drill or pin or punch held in the movable guide along a selected path to form an entry access. The straight guide portion has a plurality of notches for holding or coupling the first arm at or in proximity to a second end of the first arm. The selected path extends toward the virtual pathway to form the entry access using intra articular localization.
