Method and apparatus for determining a dorsiflexion angle
First Claim
1. Apparatus for determining a dorsiflexion angle of a surgical patient'"'"'s foot relative to the corresponding leg during tendon surgery, said apparatus comprising:
- a leg member having a first support adapted for engaging the patent'"'"'s leg adjacent 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 the patent'"'"'s leg adjacent another of the lateral malleolus and the medial malleolus of the patient; and
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 having a metatarsal support adapted for engaging the patent'"'"'s leg adjacent a predetermined point on at least one preselected metatarsal bone of the patient.

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.

18. A method for determining an angle of dorsiflexion of a surgical patient'"'"'s foot during tendon surgery, said method comprising the steps of:
-
establishing a first plane corresponding to the patient'"'"'s leg by locating a lateral malleolus of the patient, locating a medial malleolus of the patient, and locating a predetermined point on the patient'"'"'s leg above the lateral malleolus and the medial malleolus;
establishing a second plane corresponding to the patient'"'"'s foot by locating a first metatarsal head of the patient and locating a second metatarsal head of the patient; and
measuring an angle between the first plane and the second plane to determine the dorsiflexion angle of the patient'"'"'s foot.

19. Apparatus for determining a dorsiflexion angle of a surgical patient'"'"'s foot relative to the corresponding leg during tendon surgery, said apparatus comprising:
-
a leg member having a first support adapted for engaging the patent'"'"'s leg adjacent at least one of a lateral malleolus and a medial malleolus of the patient, a second support opposing the first support adapted for engaging the patent'"'"'s leg adjacent another of the lateral malleolus and the medial malleolus of the patient, and a reference arm extending from at least one of the first support and the second support adapted for engaging the leg of the patient at a predetermined point above the lateral malleolus and the medial malleolus of the patient; and
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 having a metatarsal support adapted for engaging the patent'"'"'s leg adjacent a predetermined point on at least one preselected metatarsal bone of the patient. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
