Intraop, intraoperatively; Postop., postoperatively; Fx, fracture; NR, not reported; JSES, Journal of Shoulder and Elbow Surgery.
Intraoperative glenoid fracture rates and intraoperative humerus fracture using modern non-Grammont designs have significantly decreased compared with Zumstein et al (JSES, 2011).
