This is a case study to evaluate the adequacy of fixation and functional outcome of the glenoid anchor peg following autologous bone grafting around the prosthesis at the time of implant.

To investigate if the use of autologous bone graft around the anchor-peg glenoid prosthesis correlates with bony apposition on computed tomography scans, decreased radiolucent lines and component loosening, and functional outcomes. We hypothesize that by utilizing autologous bone graft from the resected humeral head, placed around the anchor peg glenoid prosthesis at implantation, there is a low incidence of glenoid loosening. We suggest that the absence of radiolucent lines correlated with excellent shoulder function.

Inclusion Criteria:

• Patients who received a total shoulder replacement with an anchor peg glenoid and autologous bone grafting from the investigator of this study will be recruited for this study.

Exclusion Criteria:

• Patients will be excluded if they are unable to comprehend the consent information.
• Pregnant women will be excluded from this study.

Maximum number will be 70. Patients who received a total shoulder replacement with an anchor peg glenoid and autologous bone grafting from the investigator of this study will be recruited for this study.
