  • Publication number: 20200113632
    Abstract: A method of pre-operatively developing a reverse shoulder arthroplasty plan can include receiving an image of a patient shoulder comprising a humerus and a glenoid. The image can be segmented to develop a 3D shoulder model. Virtual surgery can be performed on the 3D shoulder model to generate a modified shoulder model. The virtual surgery can include resecting and reaming a virtual humerus of the 3D shoulder model, and reaming a virtual glenoid of the 3D shoulder model. Selection of a humeral implant and selection of a glenoid implant can be received. A virtual representation of the humeral implant can be implanted on the virtual humerus and a virtual representation of the glenoid implant on the virtual glenoid to virtually update the modified shoulder model. A range of motion of the patient shoulder can be determined and a reverse shoulder arthroplasty can be finalized based on the range of motion.

  • Patent number: 10588752
    Abstract: A modular bone model can include a bone component and an implant component that can be positioned on the bone component. The implant component can be shaped and sized to correspond to a head component of a medical implant to simulate an articulating surface of the head component. Similarly, the bone component can be shaped to simulate a natural bone to which the medical implant can be mounted. Alternatively, the head component of the medical implant can be mounted directly to the bone component to simulate the mounting on the natural bone.

  • Patent number: 10568647
    Abstract: A humeral cut guide system for a humeral head comprises: a bone-engagement member including a first patient-specific bone-engagement surface that is complementary and made to substantially mate and nest in only one position on a specific patient's humeral head; a registration member connected to the bone-engagement member including a second patient-specific bone engagement surface that is sized and made to substantially mate and nest in only one position with the specific patient's bicipital groove; a first protrusion extending from the registration member and having a first surgeon-engaging surface for manipulation by a surgeon; and a cut guide plate connected to and extending away from the registration member such that, upon the bone-engagement member mating and nesting with the specific patient's humeral head, the cut guide plate is spaced apart from the humeral head, wherein the cut guide plate defines an elongate slot.

  • Publication number: 20200046381
    Abstract: A glenoid guide has an upper surface and a lower surface, wherein the lower surface is a patient-specific surface configured as a negative surface of a glenoid face based on a three-dimensional image of a shoulder joint of a patient reconstructed preoperatively from image scans of the shoulder joint of the patient. The glenoid guide includes an anatomic tubular drill guide extending from the upper surface along an anatomic alignment axis configured preoperatively with a patient-specific orientation and insertion location for guiding a glenoid implant into the glenoid face for anatomic shoulder arthroplasty. The glenoid guide includes a reverse tubular drill guide extending from the upper surface along a reverse alignment axis configured preoperatively with a patient-specific orientation and insertion location for guiding a glenoid baseplate into the glenoid face for reverse shoulder arthroplasty.

  • Publication number: 20190365473
    Abstract: A method of determining an optimal position of a glenoid implant. The method includes identifying a center point of a patient's glenoid fossa based on an image of the patient's glenoid fossa; determining the optimal position of the glenoid implant based on the location of the center point relative to a medial point of the patient's scapula; and selecting orientation of an alignment pin based on the determined optimal glenoid implant position such that the glenoid fossa will be prepared to receive the glenoid implant at the optimal position when the glenoid fossa is prepared with a cutting device or guide coupled to the alignment pin.

The elongated cutting arms can extend along a second axis that is generally perpendicular relative to the first axis. The first hub can define a track thereon. The second hub can extend along a third axis. The second member can have a second pair of elongated cutting arms that are fixed to the second hub and extend along a fourth axis that is generally perpendicular to the third axis. The second member can have a track follower extending thereon and that is configured to slidably advance along the track causing the first and second members to move between a collapsed position and an expanded position.
