Orthopedic arthrodesis dowel placement guide, systems, and methods for treating mid-foot disorders
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 2 nd and 3 rd 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.
1 . An orthopedic arthrodesis dowel placement guide, comprising a guide member having a distal end configured to removably couple to a dowel; and a screw guide reciprocally translatable along the guide member, the screw guide having a least one bore member coupled thereto, extending therefrom, and positioned to approximate with a bone and configured to allow a drill bit and a screw to pass through the at least one bore member and into the bone, wherein the screw guide further comprises a collar that concentrically engages with the guide member, and at least two generally diametrically opposed arms extending from the collar, each of the at least two generally diametrically opposed arms having a bore member at an end thereof, wherein the bore member at the end of each of the diametrically opposed arms are generally parallel to a longitudinal axis of the guide member.
2 . The dowel guide according to claim 1 , wherein the screw guide further comprises an elongate arm having the at least one bore member at a distal end of the elongate arm and extending generally orthogonal to a longitudinal axis of the elongate arm.
3 . The dowel guide according to claim 2 , wherein the elongate arm is arcuate along its longitudinal axis.
4 . The dowel guide according to claim 3 , wherein the at least one bore member is oriented in a transverse alignment with the dowel and along a longitudinal axis of a mid-foot bone.
5 . The dowel guide according to claim 1 , wherein the bore member at the end of each of the diametrically opposed arms having a proximal opening and a distal opening configured to allow a drill bit to pass there through and into bone tissue at opposing portions of a resected bone.
6 . The dowel guide according to claim 5 , wherein the distal opening of each of the bore members are diametrically spaced apart to position the drill bit in spaced apart relationship to the dowel.
7 . The dowel guide according to claim 1 , wherein the dowel further comprises a recess in a proximal end of the dowel, the recess extending diametrically across the proximal end of the dowel.
8 . The dowel guide according to claim 1 , further comprising a dowel affixation plate configured to engage with openings in the bone tissue radially spaced apart from the dowel.
9 . The dowel guide according to claim 8 , wherein the dowel affixation plate is configured to seat within the recess in the proximal end of the dowel.
10 . The dowel guide according to claim 9 , wherein the dowel affixation plate further comprises tissue anchor openings at opposing ends of the dowel affixation plate and tissue anchors configured to pass through the tissue anchor openings and into the bone tissue thereby securing the dowel affixation plate over the dowel.
11 . The dowel guide according to claim 9 , wherein the dowel affixation plate further comprises legs positioned at and extending orthogonally from opposing ends of the dowel affixation plate, each of the legs are configured to penetrate into the bone tissue and retain the dowel affixation plate in the bone tissue and over the dowel.
12 . An orthopedic arthrodesis dowel placement system, comprising an arthrodesis dowel, a guide member having a distal end configured to removably couple to the arthrodesis dowel; and a drill and screw guide reciprocally translatable along the guide member, the drill and screw guide having an elongate arm and a tubular member having a central bore coupled to a distal end of the elongate arm extending generally orthogonally therefrom, the central bore being positioned in substantial alignment with a medial aspect of a mid-foot bone and configured to allow a drill bit and a screw to pass through the at least one bore member and into the mid-foot bone, further comprising at least two generally diametrically opposed elongate arms, each of the at least to generally diametrically opposed arms having a tubular member positioned at an end of each of the diametrically opposed arms.
13 . The dowel guide according to claim 12 , wherein the at least one bore member is oriented in a transverse alignment with the dowel and along a longitudinal axis of a mid-foot bone.
14 . The dowel guide according to claim 12 , wherein the dowel further comprises a recess in a proximal end of the dowel, the recess extending diametrically across the proximal end of the dowel.
15 . The dowel guide according to claim 14 , further comprising a dowel affixation plate configured to engage with openings in the bone tissue radially spaced apart from the dowel.
16 . The dowel guide according to claim 8 , wherein the dowel affixation plate is configured to seat within the recess in the proximal end of the dowel and couple to opposing aspects of bone tissue of a mid-foot bone and in spaced apart relationship from the dowel.
