Systems and methods for patient specific shoulder arthroplasty

A method of producing of a Patient-Specific Instrument (PSI) system for shoulder arthroplasty, the method comprising:

• acquiring scan data of a hone in a shoulder of a patient;
• and
• virtually designing at least one shoulder PSI based on the scan data of the bone in the shoulder, wherein the virtually-designed at least one shoulder PSI comprises a main body contoured to conform to a surface of the bone in the shoulder and at least one contact support element contoured to conform to at least one corresponding contact surface of the bone in the shoulder, and wherein the contouring of the main body and the at least one contact support element is operable to provide an indication of a mispositioning of the at least one shoulder PSI relative to the bone in the shoulder.

A system for producing of a Patient-Specific Instrument (PSI) system for shoulder arthroplasty, comprising:

• one or more controllers including one or more processors and memory, wherein the memory is configured to store one or more sets of program instructions that are executable by the one or more processors, wherein the one or more sets of program instructions are configured to cause the one or more processors to:
• acquire scan data of a bone in a shoulder of a patient and
• virtually design at least one shoulder PSI based on the scan data of the bone in the shoulder, wherein the virtually-designed at least one shoulder PSI comprises a main body contoured to conform to a surface of the bone in the shoulder and at least one contact support element contoured to conform to at least one corresponding contact surface of the bone in the shoulder, and wherein the contouring of the main body and the at least one contact support element is operable to provide an indication of a mispositioning of the at least one shoulder PSI relative to the bone in the shoulder.
