摘要:
Instruments (e.g. 40) for use in anterior approach total hip arthroplasty. Instruments according to certain features of the invention connect to a shaping member (e.g., 42) such as a broach, reamer or osteotome that is used to prepare the intramedullary canal (30) of a desired femur (18) or other bone for total hip arthroplasty. Such an instrument according to such features can be configurable to allow operation on either the left or right leg, and in doing so to provide lateral offset and anterior offset (e.g., 48) of the instrument handle (e.g., 44) 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.

摘要:
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.
摘要:
Systems and methods provide patient-specific cutting blocks that allow for bone resurfacing procedures, such as milling or burring, with simplified devices. A computer assisted surgical cutting block is produced having a surface region that matches with the surface region of a patient's bone to be altered. A cutting tool may be provided having a contoured bone mating surface and a contoured and patient-specific shaped cutting guide surface, which is located in a plane above the bone mating surface. One or more channels are provided in the cutting block, and as the surgeon moves the cutting tool (a milling or burring, for example) in the channels the tool cuts the bone both laterally along the surface of the bone and vertically into the bone according to the cutting guide surface and other preselected surface features of the cutting block.

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.
