Implant and method for long bone fixation
An implant and method for fixation of long bones. The implant provides rotational, longitudinal, and bending stability. The implant comprises one or more elongated members that span the intramedullary cavity of a long bone, a distal tip that expands radially relative to the long axis of the implant, and a locking mechanism at the proximal end of the implant.
Locking System For Femoral Neck Fracture Fixation
A fixation device for providing rotation stability to a femoral neck fracture. The device includes a bone plate having at least one opening, a compression screw housing extendable through the opening of the bone plate, a compression screw being at least partially disposed within the bore of the housing and selectively moveable through the bore, and a collapsible and expandable anchoring member coupled to the compression screw. The anchoring member is configured to transition between a collapsed condition and an expanded condition upon advancement of the anchoring member from the compression screw housing to rotationally stabilize the compression screw within a femur.
Arthrodesis implant and surgical kit comprising such an implant
An arthrodesis implant (1) for promoting the osseous fusion of a first bone (2) with a second bone (3), the implant (1) comprising a primary component (4) including a primary anchoring body (5) and a male connector (6), and a secondary component (7) including a secondary anchoring body (8) and a female connector (9), the female connector (9) comprising: a main body (10) which extends longitudinally between a rear end (11) linked to the secondary anchoring body (8) and an opposite front face (12), and which has a lateral wall (14) linking the rear end (11) to the front face (12), a housing (15) formed within the main body (10) and configured to receive the male connector (6) in order to link together the primary (4) and secondary (7) components, the female connector (9) further comprising an opening (18) which is formed in the main body (10), in communication with the housing (15), and which extends continuously on both the front face (12) and the lateral wall (14), and which is sized and configured to enable a lateral introduction of the male connector (6) into the housing (15) via the opening (18), each of the primary (4) and secondary (6) components forming an integral part made in one piece, and the primary (5) and secondary (8) anchoring bodies being respectively designed to ensure the insertion and anchoring of the primary component (4) into the first bone (2), and of the secondary component (7) into the second bone (3), by impaction or by forced wedging.
Stent
A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.
Surgical navigation system support array
A system (100) and device (300) for mounting and tracking a tracker array during a surgical procedure are described. For example, the system includes a surgical navigation system (700) including a position tracking system (702) configured to track one or more tracker arrays, and a device (300) for mounting a tracker array (306) onto a patient during the surgical procedure. The device includes an intramedullary (IM) canal component (304) configured to be inserted into an IM canal (310) within a bone (312). The device further includes a tracker pin (308) configured to penetrate at least a portion of the bone and engage an inserted end (411, 413) of the IM canal component, and a tracker array (306) affixed to the tracker pin. The IM canal component is configured to engage the IM canal of the bone to stabilize the tracker array during the surgical procedure.
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.
Flush anchor snap-off apparatus
An anchor for tensile member(s) includes: a housing having a hollow interior; a collet in the hollow interior of the housing, the collet having a peripheral wall defining a central bore and an exterior surface. The collet is configured to be swaged around the tensile member(s). The collet includes longitudinal grooves in an outer surface of the peripheral wall, each defining a web configured to collapse inward in response to external compressive force. A sleeve has a peripheral wall defining interior and exterior surfaces and is disposed in the housing axially adjacent to the collet. At least one of the collet and the sleeve is tapered and the sleeve and the collet are arranged such that sleeve movement from a first position to a second position will cause the sleeve to bear against the collet, swaging the collet radially inwards around and against the tensile member(s).
Expandable fastener for orthopaedic applications
The present disclosure provides an expandable fastener for orthopaedic applications and arranged for fastening when positioned in a bore hole in bone. The fastener comprises a body having an axis. The fastener further comprises an expansion portion moveable between a contracted configuration and an expanded configuration such that, in use, the expansion portion urges outwardly from the body towards the bone surrounding the bore hole. The fastener is arranged such that ingrowth of bone between the expansion portion and the body is substantially avoided when the expansion portion is in the expanded configuration.
INTERMEDULLARY DEVICES FOR GENERATING AND APPLYING COMPRESSION WITHIN A BODY
An intramedullary device includes a central bridge region having a first end and a second end. The intramedullary device also includes a bone engaging feature at both the first end and the second end. At least one of the bone engaging features includes a first barb and a second barb which, in an unbiased condition, flare outwardly from a longitudinal axis of the central bridge region and which are capable of being elastically constrained to a constrained condition such that the first end of the central bridge region may be advanced into a hole in a first bone fragment when the first barb and second barb are elastically constrained. The first barb and second barb are prevented from being withdrawn from the hole in the first bone fragment when the first barb and the second barb are not constrained. The intramedullary device i) is cannulated, ii) generates a compressive load, and iii) comprises nitinol.
