The implant arm includes an implant shaft extending between a proximal end and a distal end of the implant arm. The anchor arm including an anchor shaft extending between a proximal end and a distal end of the anchor arm. The positioning arm coupled with the implant arm at a first end and coupled with the anchor arm at a second end.
Method for performing surgical procedures using optical cutting guides
A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.
Knee joint prosthesis system and method for implantation
A method for preparing a first bone for receiving a prosthesis. The method includes coupling a revision alignment member to a template; positioning an offset alignment bushing relative to the revision alignment member; positioning the offset alignment bushing at the first bone such that an intramedullary member seated in the first bone extends through a passage defined by the offset alignment bushing; replacing the offset alignment bushing with a first bone cutting bushing; cutting the first bone using the first bone cutting bushing as a guide; replacing the first bone cutting bushing with an offset second bone cutting bushing; providing the second bone cutting bushing with a rotational orientation corresponding to a rotational orientation of the offset alignment bushing; and cutting the first bone using the offset second bone cutting bushing as a guide to prepare the bone to receive an offset prosthesis adapter.
Surgical instruments and methods of surgically preparing a patient's tibia
A method of surgically preparing a proximal end of a tibia includes inserting an intramedullary orthopaedic surgical instrument into a medullary canal of the tibia, securing an attachment device to the intramedullary orthopaedic surgical instrument, attaching a cutting block to the attachment device, resecting the proximal end of the tibia using the cutting block to form a surgically-prepared surface, positioning a tibial base trial on the surgically-prepared surface, and inserting a keel punch through a slot defined in the tibial base trial and into the surgically-prepared surface of the tibia.
Percutaneous fixator and method of insertion
The present invention provides a technique for percutaneous intramedullary fixation. A protective outer sheath is provided for internal fixation of the proximal tibia. Additionally, a unique intramedullary plate is provided that is adapted for percutaneous insertion into the intramedullary canal of a long bone. A plate holder is also provided that may be utilized through the outer sheath to drive and position a fixation plate within the intramedullary canal.
VERTEBRAL JOINT IMPLANTS AND DELIVERY TOOLS
A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.
CHEVRON OSTEOTOMY TOOLS AND METHODS
A targeting guide is disclosed includes a handle extending substantially along a longitudinal axis. The longitudinal handle defines one or more burr holes extending from a first side of the handle to a second side of the handle. A head is coupled to a distal end of the longitudinal handle. The head defines a plurality of guide holes sized and configured to receive a k-wire therethrough.
Computer-assisted hip replacement surgery
A CAS system and method for guiding an operator in inserting a femoral implant in a femur as a function of a limb length and orientation of the femoral implant with respect to the femur, comprising a reference tool for the femur, a registration tool, a bone altering tool and a sensing apparatus. A controller is connected to the sensing apparatus to: i) register a frame of reference of the femur by calculating surface information provided by the registration tool as a function of the position and orientation of the registration tool provided by the sensing apparatus, and/or retrieving in a database a model of the femur; ii) calculate a desired implant position with respect to the frame of reference as a function of the limb length; and iii) calculate a current implant position and orientation in relation to the desired implant position with respect to alterations being performed in the femur with the bone altering tool, as a function of the position and orientation of the bone altering tool provided by the sensing apparatus and of a digital model of a femoral implant provided by the database. The database is connected to the controller for the controller to store and retrieve information relating to an operation of the controller. The computer-assisted system may be used to guide an operator in inserting a pelvic implant in an acetabulum as a function of an orientation of the pelvic implant with respect to the pelvis.
Intervertebral Disc Implants And Tooling
A kit for preparing an intervertebral disc space for receiving an implant (100) includes a plurality of trials (152) having different sizes. Each trial (152) includes a body (154) insertible into an intervertebral disc space, the body (154) having a leading end (162), a trailing end (164), a top surface (156) and a bottom surface (160), the top surface of the body having a first groove (176) formed therein. Each implant also includes a flange (166) secured to the trailing end (164) of the body (154), the flange (166) having a first channel (180) aligned with the first groove (176), wherein each of the different sized trials has a different flange thickness. The flange thickness controls advancement of a cutting tool such as a chisel (192) into the first groove at the top surface of the trial body, which controls the depth of the cut into vertebral bone.
Systems for and methods of preparing a sacroiliac joint for fusion
A method of surgically preparing a sacroiliac joint comprising: a) approaching a sacroiliac joint space with a joint preparation tool comprising a cutting element including an exterior having an asymmetric cutting band such that the first side includes a first surface having a first texture and the second side includes a second surface having a second texture, the first and second textures being different such that the first texture is substantially smoother than the second texture; and b) delivering at least a portion of the cutting element non-transversely into the sacroiliac joint space for decortication, the cutting element being oriented in the sacroiliac joint space such that the first surface opposes the generally softer sacrum and the second surface opposes the generally harder ilium in order to more aggressively prepare the surface of the ilium while not over-preparing the sacrum to provide a robust biologic environment for intra-articular fusion.
