Abstract
Devices, systems and methods for surgical treatment of mid-foot disorders such as osteoarthritis, spacing disorders, or alignment disorders, including mid-foot arthroplasty devices and systems for the 2nd and 3rd tarsometatarsal (TMT) joint, implants for post-osteotomy spacing and realignment, arthroplasty articular implants, dowel grafts for TMT arthrodesis or fusion, dowel grafts for navicular cuneiform (NC) arthrodesis, dowel grafts for intercuneiform arthrodesis, and/or locking dowels for joint fusion.
Claims16
A dowel guide for placing arthrodesis dowels in mid-foot bones, the dowel guide comprising an instrument having at least two guide bores and at least two guide plates each having a guide opening;
- the at least two guide bores each comprising a tubular member having a proximal opening and a distal opening and being laterally moveable relative to each other;
- the at least two guide plates each coupled to a distal aspect of a guide bore such that the guide opening is axial alignment with the distal opening of a guide bore coupled thereto and each of the at least two guide plates having fixation wire openings passing therethrough configured to allow a fixation wire to pass into and through each opening and positionally fix each of the at least two guide bores to a mid-foot bone.
An orthopedic mid-foot arthrodesis dowel guide, comprising at least two tubular members each having central guide bores passing longitudinally there through, each of the central guide bores having proximal and distal bore openings at opposing ends of each of the tubular members;
- a plate coupled to the distal bore opening of each of the tubular members, the plate being oriented orthogonal to a longitudinal axis of the tubular member to which it is coupled;
- each plate further including a bore aperture configured to mate with the distal bore opening in the tubular member and at least one of a plurality of wire openings passing through each plate configured to accommodate an affixation wire through each of the at least one of a plurality of wire openings;
- and means for distracting the at least two tubular members relative to one another.
A method of distraction adjacent bones for placing arthrodesis dowels in mid-foot bones, further comprising the step of:
- a. engaging a distractable dowel guide to a mid-foot arthrodesis site, the distractable dowel guide having at least two guide bores and at least two guide plates each having a guide opening;
- the at least two guide bores each comprising a tubular member having a proximal opening and a distal opening and being laterally moveable relative to each other;
- the at least two guide plates each coupled to a distal aspect of a guide bore such that the guide opening is axial alignment with the distal opening of a guide bore coupled thereto and each of the at least two guide plates having fixation wire openings passing therethrough configured to allow a fixation wire to pass into and through each opening and positionally fix each of the at least two guide bores to a mid-foot bone;
- b. Affixing a plurality of fixation wires through the plurality of fixation wire openings and into at least one mid-foot bone and positionally affixing the distractable dowel guide to the mid-foot bones;
- c. Distracting the mid-foot bones with the distractable dowel guide;
- d. Creating a dowel placement site in the mid-foot bones through the at least two guide bores;
- e. Placing at least one dowel into the dowel placement site;
- and
- f. Removing the distractable dowel guide from the mid-foot bones.
