Abstract: A device for use in making biomechanical or orthopedic evaluations of the lower leg and foot employs a heel stationing arrangement to automatically provide a reference line parallel to the vertical bisection of the calcaneus bone. A forefoot measuring device is utilized to measure the angular deformity of the forefoot (varus or valgus) by determining the angular deviation of the plane of the ball of the foot with respect to a plane perpendicular to the heel reference line. The forefoot measuring arrangement is adaptable to measure either the plane of the ball of the foot as determined by all five rays or as determined by any desired grouping of rays, such as the second through the fifth rays. A rearfoot measuring arrangement measures the angular deformity of the rearfoot (varus or valgus) by determining the vertical bisection of the lower leg with respect to the heel reference line. Further, the device has an attachment to measure the dorsiflexion and plantarflexion of the foot about the ankle.
