  • 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.

  • Patent number: 10245164
    Abstract: A glenoid trial and implant assembly for use in reverse total shoulder arthroplasty is provided along with a method for using the same. The glenoid trial and implant assembly includes a baseplate assembly, an adapter assembly, a glenoid trial, a glenoid implant, a humeral cup, and a positioning guide. The glenoid trial is coupled to the adapter assembly when the glenoid trial and implant assembly is assembled in a trialing configuration. The glenoid implant is coupled to the adapter assembly when the glenoid trial and implant assembly is assembled in an installed configuration. A temporary connection, which may be magnetic, releasably couples the glenoid trial to the adapter assembly and provides separation of the glenoid trial and the adapter assembly without requiring disassembly of the adapter assembly. A permanent connection fixes the glenoid implant to the adapter assembly.

  • Publication number: 20180193150
    Abstract: The disclosure includes methods and systems for making orthopedic connections where there is unique adjustability to the connection. Illustratively, one embodiment provides a connecting assembly for connecting a plurality of orthopedic components. Such connecting assemblies can include a first orthopedic component that provides a female bore. Additionally, the assembly can include a second orthopedic component that can be or include a male-type connecting member that is positionable in the bore of the first orthopedic component. In one preferred form, the male-type connecting member will be a quasi-spherical member. The quasi-spherical member can include a textured outer surface, e.g., for contacting one or more walls or surfaces in the bore in a fashion that removably locks or helps to removably lock or fix the quasi-spherical member in the bore.
