Abstract
A gauge to measure the lateral inclination of a part of a brace above a patient's knee relative to a part of the brace below the patient's knee. The brace has a hinge to allow flexing of the knee. The gauge has a calibrated body that can be attached to the hinge of the brace. Limbs extend from each end of the body. There is a pivotal joint to allow each limb to pivot relative to the calibrated body. There is a reciprocable extension at the outer most end of each limb that is able to extend to contact the brace. A marker extends from the inner end of the limbs to indicate on the calibrated body the inclination of each limb. In this way the extension can be reciprocated to contact the brace and a reading them made of each marker on the calibrated scale to determine the inclination of each limb of the gauge and thus of the knee.
