Poly-faced bone fusion implant
A bone fusion implant is provided for treating conditions of Proximal Interphalangeal (PIP), Distal interphalangeal (DIP), and metatarsophalangeal (MTP) foot joints. The bone fusion implant may be a cortical bone allograft sized to fuse the foot joint to be treated. A proximal portion of the implant may be pressed into a hole drilled in a proximal bone portion of the foot joint, and a distal portion of the implant may be pressed into a hole drilled in a distal bone portion of the foot joint. Ramps on the proximal and distal portions facilitate press-fitting the implant into the holes in the bone portions. Side ramps ensure that the bone fusion implant remains substantially aligned with the foot joint while the distal portion is pressed into the hole into the distal bone portion. Grooves on the ramps alleviate pressure and ease inserting the implant into the holes in the bone portions.
CANNULATED BONE IMPLANT AND METHODS OF USE
Various methods for surgically inserting cannulated implants are disclosed.
Orthopedic implant and methods of implanting and removing same
Illustrative embodiments of orthopedic implants and methods for surgically repairing hammertoe are disclosed. According to at least one illustrative embodiment, an orthopedic implant includes a proximal segment comprising a number of spring arms forming an anchored barb at a first end of the implant, a distal segment extending between the proximal segment and a second end of the implant, and a central segment disposed between the proximal and distal segment.
Interphalangeal arthrodesis implant
This interphalangeal arthrodesis implant comprises a proximal anchor portion intended to be engaged and anchored in the medullary canal of a first phalanx sectioned along a first osteotomy plane, the proximal anchor portion including a plurality of proximal anchor branches each provided with at least one bone anchor element; and a distal anchor portion, connected to the proximal anchor portion, intended to be engaged and anchored in the medullary canal of a second phalanx sectioned along a second osteotomy plane, the distal anchor portion including a plurality of distal anchor branches each provided with at least one bone anchor element. The distal anchor portion comprises a stop portion including a stop surface intended to bear against a sectioned surface of the first phalanx extending along the first osteotomy plane.
Hammertoe implant and instrument
A bone implant comprising an elongate body having a first end and a second end coupled by a shaft is disclosed. The first portion is configured to couple to a first bone. The second portion comprises a first expandable section comprising at least one expandable feature. The first expandable section is configured to be received within a reverse countersink in a second bone in a collapsed state and to expand within the reverse countersink. The expandable feature couples to a bearing surface of the reverse countersink. A surgical tool comprising a shaft and at least one expandable cutting edge is disclosed. The shaft is sized and configured to be received within a canal formed in a bone. The expandable cutting edge is formed integrally with the shaft. The expandable cutting edge is configured to expand from a collapsed position to an expanded position for forming a reverse countersink.
ARTHRODESIS IMPLANT AND INSTRUMENT FOR GRIPPING SUCH AN IMPLANT
The invention concerns an arthrodesis implant (1) allowing promoting the bone fusion of two bones, said implant (1) comprising: a rigid and non-deformable anchoring body (4), designed to ensure the anchoring of the implant (1) in a first bone (2), a deformable portion (5) designed to ensure the anchoring of the implant (1) in a second bone, said deformable portion (5) comprising at least two anchoring arms (9, 10) which protrude beyond the anchoring body (4) from the base end (7) of the latter, the anchoring arms (9, 10) being separated from each other by a free space (E) so as to be able to be brought closer to each other by deformation of said anchoring arms under the action of the second bone. and being characterized in that at least one of the anchoring arms (9, 10) is provided with a longitudinal reinforcing fin protruding beyond the anchoring arm (9, 10) from a lateral side (20) of the latter. Osteosynthesis surgical implants.
Tapered, cylindrical cruciform hammer toe implant and method
An implant is disclosed including an elongated threaded portion and a blade portion extending from the elongated threaded portion. The blade portion has a substantially cylindrical cross-sectional geometry and a taper defined by a plurality of blades.
Titanium plasma coated medical grade thermoplastic or polymer proximal and distal interphalangeal toe implant
A medical grade thermoplastic or polymer implant with an osteoconductive coating is provided, specifically for corrections of the distal and proximal interphalangeal toe joints of the foot. The implant can be either straight or angled, and can be either solid or cannulated for insertion. The implant is sized and shaped depending on the specific anatomy and desired correction. End portions of the implant may be coated with an osteoconductive coating that promotes bone growth, but may reduce radiolucency. Thus, a central portion of the implant may remain uncoated to increase radiolucency of the implant at the region where two bones come together.
BONE FIXATION DEVICE AND METHOD OF USE
An implant including a first segment at a first end, a second segment at a second end, and an intermediate segment coupled to the first segment on a first end and coupled to the second segment on a second end. The first segment may include an insertion tip at the first end of the implant and a body portion adjacent to the insertion tip, the insertion tip extending out from the body portion. The second segment may include an end member at the second end of the implant and a body portion adjacent to the end member, the end member extending out from the body portion. The second segment may include a plurality of tip portions spaced about a longitudinal axis of the second segment, and the tip portions each including at least one barb formed by a taper portion and an engagement portion extending radially into the tip portion.
Implants, systems, and methods of use and assembly
Implants, devices, systems and methods for maintaining, correcting and/or fusing joint deformities are disclosed. The implant including a first member, a second member, and a coupling member with a first end and a second end, wherein the first end engages the first member and the second end engages the second member. Methods of using the implants for maintaining, correcting and/or fusing joint deformities are also disclosed.
