  • Patent number: 10537342
    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: 10517714
    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: 10492798
    Abstract: A method for preparing a backup kit for a plurality of patient-specific arthroplasty procedures scheduled at the same medical facility includes providing a database with data from completed arthroplasty procedures using patient-specific arthroplasty kits. The database includes comparisons between preoperatively planned implant size and intraoperatively implanted implant size. The method includes determining a statistically expected implant size deviation from a planned implant size for each implant included in a plurality of patient-specific arthroplasty kits prepared for a shipment to the medical facility using the database. A backup kit of backup implants is assembled for the shipment. The number and size of the backup implants is determined from the statistically expected implant size deviations.

  • Publication number: 20190336144
    Abstract: An orthopedic device for a shoulder joint includes a patient-specific alignment guide. The alignment guide includes a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to be complementary and closely mate and conform to a humeral head of a proximal humerus of a patient. The alignment guide includes a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and orientation determined in the pre-operative plan, and an orientation feature on the cap. The orientation feature is designed to orient the cap relative to the humeral head when the orientation feature is aligned with a landmark of the proximal humerus.

  • Publication number: 20190269422
    Abstract: An instrumentation set for preparing a proximal tibia during a bi-cruciate retaining procedure can include a tibial resection block and a stylus. The tibial resection block can be configured to be fixed to an anterior portion of the proximal tibia. The tibial resection block can define a slot that extends in a medial-lateral direction when the tibial resection block is fixed to the proximal tibia. The stylus can have a first block attachment feature and a second block attachment feature. The first block attachment feature can be offset from the stylus a first distance. The second block attachment feature can be offset from the stylus a second distance. The first and second block attachment features of the stylus can be selectively and alternatively received by the slot of the tibial resection block to position the stylus at distinct offset locations relative to the slot.

  • Publication number: 20190223885
    Abstract: A medical device for preparing an elongated bone, such as a proximal femoral bone, for receiving an implant includes a patient-specific femoral guide and an elongated alignment element. The femoral guide has a patient-specific three-dimensional bone-engaging surface configured according to a preoperative plan based on a three-dimensional image model of the femoral bone to mate complementarily with the surface of the proximal femoral bone extending between the greater trochanter, the femoral neck and the femoral shaft of the proximal femur. The femoral guide includes a first guide end forming a planar guide configured for guiding a neck resection. The alignment member can be removably attached to the femoral guide and defines a reference axis for guiding a cutting tool into the femoral bone through a resected surface of the femoral neck.

  • Patent number: 10238399
    Abstract: A method of positioning a femoral cutting guide on a distal end of a femur establishes at least a first reference plane to perform a distal femoral planar cut. The method includes inserting a mounting member into an intramedullary canal of the femur and coupling a bridge member to the mounting member. The method also includes placing a cutting guide member over a medal anterior portion of the distal femur. The cutting guide member has a first channel that establishes the first reference plane. The bridge member has a bridge channel. A wall of the bridge channel is inserted into the first channel of the cutting guide member. A mounting mechanism generates resistance between the bridge member and the cutting guide member. The resistance is overcome by positioning the cutting guide member relative to the femur.
