Abstract
Apparatus for determining a dorsiflexion angle of a surgical patient's foot relative to the corresponding leg during tendon surgery. The apparatus includes a leg member having a first support adapted for engaging at least one of a lateral malleolus and a medial malleolus of the patient, and a second support opposing the first support adapted for engaging another of the lateral malleolus and the medial malleolus of the patient. The apparatus further includes a foot member rotatably connected to the leg member for selectively rotating the foot member relative to the leg member about an axis defined by the first support and the second support of the leg member. The foot member has a metatarsal support adapted for engaging a predetermined point on at least one preselected metatarsal bone of the patient.
