Baseline's Large Joint Protractor is designed to provide accurate measurements of joint range of motion. It features two arms: a stationary arm aligned with the bone's long axis and a movable arm that is positioned over the joint being measured and follows its direction of movement.

Measuring the angle between the two arms in 5° increments, up to a total of 180°, the device also utilizes a bubble level for precise measurements on a horizontal plane.
