摘要:
The present invention provides integration between an implant system and therapeutic agent delivery system. The implant may include a prosthesis that restores biomechanical function while decreasing long-term disability and pain by replacing damaged or degenerate tissues, or a reconstructive implant such as a bone plate. The therapeutic agent delivery system may include one or more channels either permanently or reversibly attached to the implant. The channels may receive medication from an external pump via a percutaneous catheter. The channels deliver the medication to one or more medicating surfaces of the implant to treating proximate tissues.

Improved surgical instruments are provided including improved suture passers, improved drill guides for forming holes in bones adjacent a joint at locations referenced to the joint anatomy, and improved osteotomy guides.

A line lock includes a body at least partially bounding two passageways that cooperate to receive a locking portion of a line such as a suture in such a manner that the locking portion can only be drawn through the passageways along one direction. A second suture locking portion may also received by the passageways, or by one of the two passageways in combination with a third passageway. The body may have an elongated, compact shape that is easily implantable in the body.

Instruments and techniques to pass a suture are presented. In one illustrative example, a suture passer includes a drill guide and is able to form a tunnel in a bone and pass a suture through the tunnel so formed.

A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.
摘要:
An apparatus for inserting a suture anchor into an internal anatomical site through a cannula, or percutaneously, has a curved hollow guide for insertion into the cannula and/or tissue. The guide has a proximal end and a distal end. The distal end has a “parabolic ” shape for engaging the intended anatomical site such as a glenoid. A flexible obturator is insertable through the curved guide from the proximal end to the distal end to facilitate insertion of the guide through the cannula. A flexible drill is insertable through the curved guide from the proximal to the distal end once the guide is in place. A flexible inserter is provided for inserting a suture anchor into a bore at the anatomical site formed by the flexible drill.

A guide and method useful in cutting and rejoining bones is presented. The guide is particularly useful in performing an osteotomy of a long bone adjacent a joint such as a hand or foot.
摘要:
A bone plate assembly including at least one bone plate, polyaxially adjustable fixation elements and a polyaxially adjustable locking mechanism. A first plate includes at least one polyaxial element for lockable connection with a fixation pad, and a connection feature which allows the plate to translate and polyaxially rotate relative to the locking mechanism. A second plate includes at least one polyaxial element for connection with a fixation pad and a connection feature for non-rotatable connection with the locking mechanism. The locking mechanism allows translation and polyaxial adjustment of the first plate relative to the second plate and locks the first and second plates via a taper lock. The fixation pad includes a deflectable spacer configured to prevent premature locking of the pad. Methods for implantation of the bone plate assembly between bone structures are disclosed. Instrumentation for implantation, compression and locking of the bone plate assembly is disclosed.
