“…In those studies, 1.2% of all primary shoulder arthroplasties performed from 1980 to 2002 7 and 1.4% of those done with a cemented all-polyethylene glenoid component from 1990 to 2000 4 were associated with an intraoperative fracture. The postoperative humeral fracture rate (0.9%) in our study is comparable with rates reported in other studies (range, 1.6% to 2.4%) 1,2,6,17 and in a systematic review of forty studies (1.2%) with a total of 3584 patients 5 . In a previous study from our institution, the use of a press-fit humeral component was associated with a borderline significantly increased risk of intraoperative humeral fracture (p = 0.046) in a cohort treated with total shoulder arthroplasty, humeral head replacement, or revision shoulder arthroplasty from 1980 to 2002 7 .…”
