∗
Two patients had previous surgeries on their operative shoulder. One patient received an arthroscopic debridement for shoulder osteoarthritis, impingement syndrome, and acromioclavicular joint osteoarthritis. The other patient received four surgeries consisting of two open shoulder reconstructions and two arthroscopic debridement procedures to address injuries related to chronic anterior shoulder dislocations.
†
During structural graft fixation, the end of a guide pin broke inside a cannulated screw that was fixed into bone. The pin was ultimately left inside since the glenoid implant was not obstructed.
