Content

FIGURE 5B illustrates an example balance gauge 168 of a gap gauge 100 that can be positioned to contact a first bone (See FIGURE 1A) and a second bone (See FIGURE 1A). Where the surfaces of the bones are not parallel and/or forces within the joint 108 are not balanced (e.g., a varus condition or valgus condition depending on which joint is being measured), a needle 172 of the balance gauge 168 may point to a mark (e.g., -5 degrees) on the left side of the middle mark of the dial 170 indicating an imbalance or non-balanced condition, a positive or negative degree of rotation about a pivot axis 162.
