An orthopaedic implant includes an implant body having a first surface and a second surface opposite the first surface. The second surface includes a fixation feature. The fixation feature is configured to have a variable width for fastening the implant to a fixation bore formed in a bone. The implant body is D-shaped and has a straight edge and a curved edge. A length of the fixation feature is substantially parallel to the straight edge of the implant body. The fixation feature is configured to have a width that tapers along the length of the fixation feature.

Orthopaedic implant with fixation feature and a method of implanting thereof

A bone fusion method, system and device for insertion between bones that are to be fused together and/or in place of one or more of the bones, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs having a central rib. The bone fusion device includes one or more support channels configured to receive an insertion instrument that is then secured to the bone fusion device via a coupling mechanism. As a result, the coupled device is able to be securely positioned between vertebrae using the insertion instrument with minimal risk of slippage.

Bone fusion system, device and method including an insertion instrument

An orthopaedic implant includes: a base including a molding material; a first porous ingrowth material region coupled to the base; a second porous ingrowth material region coupled to the base; and at least one barrier insert coupled to the base, the barrier insert including a barrier material that is configured to prevent introduction of the molding material of the base into some pores of the first porous ingrowth material region and some pores of the second porous ingrowth material region during molding of the base.

Bone fusion system, device and method including a measuring mechanism

An orthopedic implant comprises a body having an articulating surface and a surface opposite the articulating surface. The surface opposite the articulating surface includes a fixation feature. The fixation feature is configured to have a variable width for fastening the implant to a fixation bore formed in a bone.

A bone fusion device for insertion between bones that are to be fused together, such as, for example, the vertebrae of a spinal column. The bone fusion device comprises at least one extendable tab and one or more tab extension assemblies. Each tab extension assembly is able to be adjusted in order to individually control the extension or contraction of a side of the tab thereby enabling adjustment of the height and/or angle of the tab with respect to the body of the bone fusion device. Each tab extension assembly is able to be individually adjusted such that the side controlled by each assembly is raised or lowered until the desired tab angle is achieved. The tab is advantageously positioned and angled to correspond to the vertebrae to help brace the device until the bone has fused.

An apparatus includes a cut guide including a locking area, an alignment guide, and a connect mechanism to connect the cut guide to the alignment guide, wherein the connect mechanism includes a cone lock connect mechanism configured to engage with the cut guide locking area.

An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.

Method and apparatus for reducing femoral fractures

The instrumentation set of this invention assists the surgeon in selecting the proper implant components, in determining the amount of distal bone to resect, and in aligning instrumentation designed to resect the bone. The instrumentation set provides numerous systems for verifying to the surgeon that he has correctly aligned the instruments prior to removing any bone. The set includes a rotational alignment guide, which aids the surgeon in establishing the appropriate rotational alignment for the knee as determined by reference to standard femoral landmarks such as the posterior condyles and epicondyles. The rotational alignment guide includes a slot for guiding a saw blade for removal of the posterior condyles of the femur. The set further includes a tensor designed to tense the knee joint in flexion and extension. The tensor is activated by a torque wrench so that a measured mount of tension force can be applied to the joint. The tensor is configured to slidably carry a sizing rod which contacts the femur and includes a plurality of markings, which relate to the size of the femur as well as the spacing between the femur and tibia. This information is used by the surgeon to select the proper size of femoral and tibial articulate surface components. The sizing rod also indicates to the surgeon any variation required in the amount of bone to be resected.

Instrumentation for use in orthopaedic surgery

Orthopaedic bone cutting guide

The invention is directed to an intramedullary guide rod assembly for use in orthopaedic surgery for aligning one or more milling or cutting guides. A guide member is pivotally connected to an intramedullary guide rod intermediate and proximal and distal ends thereof. An alignment mechanism selectively locks the guide member to the intramedullary guide rod between discrete predetermined positions relative the guide rod.
