Claims17
An orthopedic surgical instrument for transferring a center location of a patient's tibia to the patient's talus during a total ankle arthroplasty procedure, comprising:
- a first lever,
- a second lever pivotally coupled to the first lever,
- an upper handle secured to a proximal end of the first lever,
- a lower handle secured to a proximal end of the second lever,
- a tibial trial component secured to a distal end of the first lever, and
- an indenting spike secured to a distal end of the second lever.
3 more elements
A method of performing a total ankle arthroplasty procedure on a tibia and talus of a patient, comprising:
- inserting a center-transfer instrument such that a tibial trial component of the center-transfer instrument is received into a surgically-prepared cavity in the distal end of tibia of the patient, and
- moving a first handle and a second handle of the center-transfer handle relative one another so as to urge an indenting spike of the center-transfer handle into a surgically-prepared superior surface of the talus of the patient so as to form an indentation therein.
