Filed:

Nov 20, 2009

Appl. No.:

12/623030

Inventors:

Jeffrey A. Sharp - Memphis TN, US
Luke A. Gibson - Southaven MS, US
David C. Kelman - Collierville TN, US

International Classification:

A61B 17/16

US Classification:

606 80

Abstract:

Instruments for use in anterior approach total hip arthroplasty. Instruments according to certain embodiments of the invention connect to a shaping member such as a broach, reamer or osteotome that is used to prepare the intramedullary canal of a desired femur or other bone for total hip arthroplasty. Such an instrument according to such embodiments can be configurable to allow operation on either the left or right leg, and in doing so to provide lateral offset and anterior offset of the instrument handle relative to the shaping member so that the patient's gut, musculature or other bodily portions may be avoided while still providing desired leverage and control over the shaping member to prepare the intramedullary canal.

International Classification:

A61B 17/90
B23P 17/04

US Classification:

606 87, 29428, 606102, 606 96

Abstract:

Disclosed are lockable instrument assemblies for quick and easy configuration of surgical instrumentation. The assemblies are operable between a locked and unlocked position, and generally include an aperture having a shaped profile which receives an adjustment member therein. When the assemblies are placed in a locked assembly configuration, the adjustment member is prevented from rotating or translating within the aperture. When the assemblies are placed in an unlocked assembly configuration, the adjustment member is permitted to rotate or translate within the aperture. Also disclosed are methods of using and making lockable instrument assemblies.

US Classification:

606 88

Abstract:

Methods and apparatus for performing knee arthroplasty, including, but not limited to, bicruciate retaining knee arthroplasty, are described herein. Methods and apparatus for preparing a distal femur for a femoral implant as well as methods and apparatus for preparing a proximal tibia for a tibial implant are described. These methods and apparatus, in at least some embodiments and uses, facilitate decreasing the complexity of knee arthroplasty procedures such as bicruciate retaining procedures, while maintaining, if not improving on, the safety, accuracy and/or effectiveness of such procedures.

US Classification:

606 79, 606 86 R, 606102

Abstract:

Surgical systems and methods are disclosed for creating a 3D model of a patient's affected area using an imaging device, using the model to determine an implant orientation and position, creating patient-matched instrumentation, placing the patient-matched instrumentation on the patient's anatomy, registering a computer-assisted surgical tool, and acquiring registration information. The methods and systems also include associating the surgical tool with a computer to perform a computer assisted surgery. Also disclosed are embodiments of patient-matched instrumentation to acquire registration information.

International Classification:

A61F 2/34

US Classification:

623 2238

Abstract:

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. An augment provided for an acetabular implant may be adjustably positionable around the implant. An implant may have one or more slots that mate with connections on the augment and allow the augment to move within the slot. An augment may be translated, rotated, or moved in any other way to achieve a desired orientation prior to locking the augment in place relative to the implant. The augment may be locked by a screw or other locking mechanism that holds the augment in place. The locking mechanism may be releasable to allow for repositioning of the augment.

US Classification:

623 2235

Abstract:

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. A mounting member may be used to attach to an implant and anchor the implant to a patient's bone or soft tissue. The mounting member may be integral with the implant or may be provided as a separate component. A mounting member may be adjustably positionable around the implant to provide flexibility and allow the mounting member to meet needs of a particular patient and implant.

US Classification:

623 2224, 623 2232

Abstract:

Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.
