  • Publication number: 20170333194
    Abstract: A patient-specific augment can be attached to an implant component for a bone of a joint of a patient. The patient-specific augment has first and second surfaces. The first surface is a three-dimensional patient-specific surface that closely matches and can mate to a substantially unaltered and unresected surface of a bone defect of the specific patient only in one position. The second surface is designed to engage a non-custom surface of the implant.

  • Publication number: 20170311962
    Abstract: A cut block positioning jig including a first alignment member, a second alignment member, and both first and second guide members. The first alignment member is movable towards and away from a patient's bone to which the positioning jig is mounted to arrange the jig at a predetermined position relative to the bone based on x-rays of the patient. The second alignment member is movable towards and away from the bone to arrange the jig at the predetermined position relative to the bone. The first and second guide members are configured to direct cut block support members to the bone to couple a cut block to the bone to provide the bone with patient-specific cuts.

  • Patent number: 9795399
    Abstract: A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient. First and second holes are drilled into an anterior portion of the femoral joint surface through corresponding first and second guiding apertures of the femoral alignment guide.

  • Publication number: 20170273718
    Abstract: A method of preparing a distal femur for a knee joint implant includes mounting a patient-specific bone engagement surface of a femoral alignment guide on a complementary surface of a distal femur of a patient. A plurality of alignment pins is inserted through a corresponding plurality of guiding bores of the femoral alignment guide into the distal femur. A cutting guide is mounted on first and second alignment pins of the plurality of alignment pins, and a first resection of the distal femur is made using the cutting guide while cutting through the femoral alignment guide.

  • Patent number: 9757238
    Abstract: A pre-operative planning and manufacturing method for orthopedic surgery includes obtaining pre-operative medical image data representing a joint portion of a patient. The method also includes constructing a three-dimensional digital model of the joint portion and manufacturing a patient-specific alignment guide for the joint portion from the three-dimensional digital model of the joint portion when the image data is sufficient to construct the three-dimensional digital model of the joint portion. The patient-specific alignment guide has a three-dimensional patient-specific surface pre-operatively configured to nest and closely conform to a corresponding surface of the joint portion of the patient in only one position relative to the joint portion.

  • Publication number: 20170231645
    Abstract: An orthopedic device for cutting or resurfacing an outer bone surface of a bone of a patient includes first and second guides. Each guide has a patient-specific surface preoperatively configured as a negative surface of a portion of the outer bone surface of the bone and a plurality of elongated slots. The elongated slots of the second guide are offset relative to the elongated slots of the first guide and configured for guiding a tool to resurface the outer bone surface.

  • Publication number: 20170224496
    Abstract: An implant for a femoral head of a patient. The implant includes a shell implantable on the femoral head of the patient and correcting a defect of the femoral head. The shell is designed preoperatively to have a patient-specific first surface for articulation with the patient's acetabulum and a patient-specific periphery mateable with a periphery of the defect. The shell caps the defect and the first surface of the shell is continuous to a remaining healthy surface of the femoral head. The defect can be a bone defect, a cartilage defect or a combination thereof.

  • Patent number: 9693788
    Abstract: A system for performing a resection of a selected portion of an anatomy with a resection instrument. The system includes a first member, a first movement defining portion defined by the first member, a second member, and a second movement defining portion of the second member. The first member is fixable to the selected portion of the anatomy. The second member is configured to cooperate with the first member. The first movement defining portion and the second movement defining portion are operable to allow the second member to be moveable relative to the first member from a first position to a second position. The resection instrument is positionable relative to the second member in the first position and in the second position to form a selected resection of the selected portion of the anatomy.

  • Patent number: 9681940
    Abstract: A system for an anatomical joint includes a first fastener, a second fastener, a prosthetic ligament member, and a biasing member associated with at least one of the first and second fasteners. The first fastener is operable to be connected to a first bone portion. The second fastener is operable to be connected to a second bone portion. The prosthetic ligament member is flexible and is directly coupled to both the first and second fasteners to support the first bone portion and the second bone portion for relative movement. A portion of the prosthetic ligament member extends from the first fastener to the second fastener and has an adjustable length. The biasing member is operable to bias the prosthetic ligament member to thereby maintain tension in the prosthetic ligament member.

  • Patent number: 9662127
    Abstract: A surgical kit for preparing a joint surface to receive an implant includes a patient-specific guide for a joint surface. The patient-specific guide has a patient-specific surface complementary to a surface of the joint for nesting engagement, and a guiding element oriented along a patient-specific alignment axis. The alignment axis is determined during a preoperative plan of the specific patient for implant alignment. The kit includes a guiding tool couplable to the guiding element of the patient-specific guide and a three-dimensional orientation device removably couplable the guiding tool for intra-operative calibration, such that, after calibration, the orientation device can be removably coupled to a shaft of a surgical instrument to align the shaft along the alignment axis.
