A rail assembly for a knee positioning system that includes a base and a pair of rails removably coupled to the base. Each of the rails defines a plurality of positioning slots formed therein, each of the positioning slots being at least partially aligned with a corresponding positioning slot of the other rail. At least one of the rails and the base form at least one cleanout channel therebetween that is configured to receive a cleaning fluid for removing contaminants that collect on the at least one rail and the base.

Knee positioning system with cleanout channel

An implant system for total shoulder arthroplasties, hemi shoulder arthroplasties, and 'reverse' total shoulder arthroplasties including a humeral stem having an enlarged head portion with interfaces adapted to removably receive various modular interchangeable components, such as articulating liners, spacers, and adapter inserts. The humeral stem functions as a universal platform that may be used in either conventional or 'reverse' total shoulder arthroplasties, as well as hemi shoulder arthroplasties, and may remain implanted in place during a revision in which the implant system is converted between the foregoing configurations, for example.

Shoulder arthroplasty system

A prosthetic for use in an interphalangeal joint including a body portion and a weave portion. The body portion may be manufactured from a hydrogel material. The body portion includes an pair of stems and an intermediate section located in between the two stems. The intermediate section includes a recess allowing for flexing of the body portion.

Hydrogel proximal interphalangeal implant

The present invention relates to a set of tools and accessories used for properly positioning a stemmed humeral component, and/or a humeral stem provisional, within a canal in the humerus. The set of tools and accessories includes one or more fin clamps that are configured to be temporarily attached to a fin on the humeral component or the provisional; a ruler that is configured to be attached to the arm of the fin clamp, a fixation pin and pin driver configured to be used with the other tools for marking a position on the humerus; and one or more sleeves that are configured to slide over the stem of the humeral stem provisional to maintain it in the desired position.

Method and instruments for positioning humeral component during shoulder arthroplasty

A blade plate, as well as instruments and methods for securing the blade plate to a bone to reduce a bone fracture. The blade plate includes a plate portion and a blade portion extending at an angle relative to the plate portion. The plate portion includes a plurality of holes for receipt of bone screws for securing the blade plate to the bone about the bone fracture. A strut screw, inserted through a hole in the plate portion, spans the angle between the plate and blade portions, and threadingly engages a hole in the blade portion to slightly draw the plate and blade portions together to compress and support the bone fracture. A pair of top screws are inserted through holes in the plate portion at angles with respect to the strut screw on either side of the strut screw. Additionally, the blade plate is designed to closely conform to the surface of the bone to minimize the gap between the bone and the blade plate. In order to secure the blade plate to a bone, a chisel/drill guide, chisel, insertion guide, and screw drill guides are provided.

Blade plate and instruments

A method and apparatus for facilitating shoulder arthroplasty by providing a reference to establish version of the glenoid. In one form of the invention, a guide for positioning a guide pin to facilitate implantation of a glenoid prosthesis is provided. To properly position the guide pin, the guide is first oriented with respect to the scapula. A portion of the guide is positioned over the approximate center of the glenoid surface and another portion of the guide is positioned against the anterior surface of the scapula. After the guide is properly positioned, the guide pin is inserted through an aperture in the guide and anchored in the glenoid. Thereafter, the guide pin can serve as an alignment guide for other devices used to modify the glenoid surface. For example, a reamer having a cannulated central shaft can be placed over the guide pin and utilized to resurface the glenoid.

Method and apparatus for preparing a glenoid surface

A suture anchor system adapted for securing a suture to a bone. The suture anchor system includes a suture anchor which retains a portion of the suture within the bone. A driver handle having a first end and second end with a bore passing therethrough receives a portion of the suture anchor at the first end. A starter plunger having a first head and a first drive member is received at the second end of the driver handle. The starter plunger drives the suture anchor at least partially into the bone to a first depth. An insertion plunger having a second head and a second drive member is received at the second end of the driver handle. The insertion plunger drives the suture anchor fully into the bone to a second depth.

A version adjustment instrument is utilized with modular femoral components, including a modular stem component having a coronal slot and/or a bowed portion and a modular body component attachable to the modular stem component in a substantially fixed orientation relative to the coronal slot or bowed portion. The instrument includes a base with a face surface having a plurality of adjacent angle markings. A body component support has a first coupler formed to engage the modular body component in a substantially fixed orientation relative to the body component support. A stem locator has a second coupler formed to engage one of either the coronal slot or bowed portion (if any) of the modular stem component in a substantially fixed orientation relative to the stem locator. One of the body component support or the stem locator is connected to the base at a position away from the face surface in a substantially fixed orientation relative to the angle markings. The other of the two is rotatably mounted to the base about an axis of rotation and includes a pointer projecting away from the axis of rotation with a portion adjacent the angle markings.

Version adjustment instrument for modular femoral components and method

An apparatus and a method for providing initial mechanical fixation of a hamstring graft and subsequent biologic bonding of the graft to the walls of a femoral tunnel. The apparatus includes a two-part screw assembly that is introduced through the lateral femoral condyle. The two-part screw assembly includes an outer screw and an inner screw. The outer screw includes a threaded body and an outwardly-extending nose portion that is of a diameter reduced from the threaded body. The nose portion provides a mechanical fixation point by functioning as a post within the femoral tunnel. A hamstring graft is looped around this post, mechanically fixing one end of the graft. Bone reamings, or mulch, is inserted using a bone graft impactor tool through a hollow throughbore axially defined within the body of the outer screw. The throughbore is in communication with an opening adjacent the nose portion and the mulch is deposited into the femoral tunnel around the tendon loop. The inner screw is inserted into the throughbore.
