Embodiment Construction

[0027] Applicants have found that mechanically and biologically treating the bone to restore normal physical stress distribution and restore the healing balance of the subchondral bone tissue is a more effective way to treat pain than traditional techniques. That is, therapy can be effectively achieved by mechanically enhancing or stabilizing the defect, and biologically initiating or stimulating a healing response to the defect. Accordingly, the present disclosure provides methods, devices, and systems for subchondral procedures. This process and its associated devices, instruments etc. are also marketed under the registered trade name SUBCHONDROPLASTY(TM). The SUBCHONDROPLASTY(TM) procedure was developed to meet the needs of patients facing partial or complete knee replacements who wanted an alternative.

[0028]Typically, SUBCHONDROPLASTY(TM) or SCP(TM) techniques are designed to strengthen and stimulate bone. In SCP(TM), fractures or non-unions are stabilized, integrated...

Abstract

A coordinate mapping system is provided for locating a defect in a bone. The system comprises a positioning instrument for controlled delivery of a device to a target site, the instrument comprising a main body and a rail extending from the main body, the rail including a series of indicia corresponding to predefined grid lines, and a template configured to overlay an image of a bone having a defect at the target site, the template including a predefined grid for determining a set of coordinates to locate the target site using the positioning instrument. A method of accessing a target site near a defect in a bone using the radial coordinate mapping system is also provided.

Description

technical field [0001] The present invention relates to devices and tools for the surgical treatment of joints, and more particularly to instruments and related methods for the surgical repair and treatment of bone tissue at these joints. More specifically, the present invention relates to a coordinate mapping system for locating bone defects using anatomical landmarks. Background technique [0002] Human joints, especially the knees, hips, and spine, are prone to deterioration from disease, trauma, and prolonged repeated use that ultimately lead to pain. For example, knee pain results in substantial medical and related healthcare costs. The most popular theory stemming from the medical community is that knee pain comes from insufficient cushioning of bone-to-bone contact or cartilage. These conditions are thought to frequently result from the development of osteoarthritis, which is measured by narrowing of the joint space. Therefore, the severity of osteoarthritis is con...
