System and technique for accessing extra articular lesions or abnormalities or intra osseous lesions or bone marrow lesions
First Claim
1. A technique for accessing extra articular lesions or abnormalities or intra osseous lesions or abnormalities or bone marrow lesions or all, comprising the steps of:
- pinning an intra articular localizing pinning member by inserting the localizing pinning member through cartilage and / or subchondral bone into a lesion or abnormality to locate and stabilize by intra articular pinning the lesion or the abnormality with the localized pinning member to create a first entry access, wherein the localizing pinning member is configured to be left in the first entry access and includes a graduated or calibrated depth scale on a shank of the localizing pinning member to indicate the distance to a tip or end of the localizing pinning member;
attaching a guide component onto the pinning member over an exposed portion of the localizing pinning member when pinned in the lesion or the abnormality, the guide component having a first arm with an end with a shank tightening nut for attachment to the localizing pinning member and a second arcuate arm;
positioning the guide component at a predetermined position on the shank of the localizing pinning member while maintaining the guide component movable about the localizing pinning member;
manipulating the guide component to achieve a desired path and rotational position along or about the localizing pinning member by rotating the guide component about the localized pinning member to establish a desired location for the creation of a second entry access based on relevant anatomy to form a blind angled osteal tunnel or channel and tightening the shank tightening nut to secure the guide component to the localizing pinning member, wherein the guide component includes a movable guide which is continuously adjustable along a circumferential arc on the guide component anywhere along a portion of the second arcuate arm of the guide component to be set or fixed at the desired second entry access point;
positioning the movable guide along the second arcuate arm at the desired second access point; and
utilizing the fixed or set movable guide of the guide component for passing a drill, a pin or a punch through the guide component to the second entry access to a desired depth within or in the proximity of the lesion or the abnormality.

Abstract
A technique for accessing extra articular lesions or abnormalities or intra osseous lesions or abnormalities or bone marrow lesions or all has the step of utilizing an intra articular localizing pinning member to determine a location of the lesion or abnormality wherein the utilization of the localizing pinning member includes the step of inserting the localizing pinning member through cartilage or subchondral bone into the lesion or abnormality to locate or stabilize or both creating a first entry access. The localizing pinning member enters the bony lesion or abnormality penetrating at least into or through the lesion or abnormality to set the localizing pinning member to the desired depth.
