Persistent shoulder instability following joint arthroplasty remains a concern with mixed outcomes following clinical and surgical intervention. Thus, a linked universal joint implant was developed and functionally analyzed. A virtual model of the linked implant was developed and implanted in a 3D bony specimen to measure the available circumduction range of motion. Stresses in the implant were estimated using finite element analysis based on joint loads during activities of daily life. The glenoid fixation stress was evaluated using finite element analysis.

The implant was capable of restoring normal range of motion, and withstanding expected joint loads without yield or fatigue failure. Bone fixation stress remains a concern, depending on the implant configuration and aggressive joint loading.
