Shoulder joint implant selection system

A selection system configured to support selection prosthetic components during shoulder surgery, the selection system comprising:

• a ring configured to be coupled directly to a first bone of a shoulder joint,
• wherein the ring includes a retaining feature;
• at least one fastener configured to couple the ring to the first bone of the shoulder joint,
• a measurement device having a plurality of sensors located at radial positions relative to an external curved surface,
• wherein the measurement device is configured to be coupled directly to the ring,
• wherein the measurement device comprises an external surface that is configured to articulate with a shoulder prosthetic component that is coupled to a second bone of the shoulder joint,
• wherein the measurement device generates measurement data configured to support the selection of (a) the shoulder prosthetic component that is coupled to the second bone of the shoulder joint, (b) a further shoulder prosthetic component that is configured to be coupled to the first bone of the shoulder joint, or (c) both, and
• wherein the measurement device supports movement of the shoulder joint;
• a computer;
• and
• a display coupled to the computer,
• wherein the computer is configured to:
• (a) receive the measurement data from the measurement device,
• (b) process the measurement data, and
• (c) operate the display to display the measurement data in real-time for use by a surgeon or surgical team,
• wherein the measurement data above a predetermined threshold supports the selection of a first prosthetic component, and
• wherein the measurement data below the predetermined threshold supports the selection of a second prosthetic component.

A selection system configured to support selection of prosthetic components during shoulder surgery, the selection system comprising:

• a ring configured to be coupled directly to a humerus of a shoulder joint;
• at least one fastener configured to couple the ring to the first bone of the shoulder joint, wherein the at least one fastener includes at least one of a nail or a screw;
• a measurement device having a plurality of sensors located at radial positions relative to an external curved surface,
• wherein the measurement device is configured to be coupled directly to the ring,
• wherein the measurement device generates measurement data configured to support selection of (a) the shoulder prosthetic component that is coupled to the second bone of the shoulder joint, (b) a further shoulder prosthetic component that is configured to be coupled to the first bone of the shoulder joint, or (c) both,
• wherein the measurement device supports movement of the shoulder joint, and
• wherein the measurement device is configured to measure a position of applied load and a load magnitude at the position of applied load;
• a computer;
• and
• a display configured to be coupled to the computer,
• wherein the computer is configured to:
• (a) receive the measurement data from the measurement device,
• (b) process the measurement data, and
• (c) operate the display to display the measurement data in real-time for use by a surgeon or surgical team,
• wherein an offset of the selection system is between an offset of an in-lay humeral prosthetic component and an offset of an on-lay humeral prosthetic component,
• wherein the in-lay humeral prosthetic component is selected if the measurement data is within a range of 20-40 lbs., and
• wherein the on-lay humeral prosthetic component is selected if the measurement data is within a range of 0-20 lbs.
