Moverman MA, Menendez ME, Mahendraraj KA, et al. - A multicenter study was performed to evaluate the incidence of acromial stress fractures (ASFs) after reverse total shoulder arthroplasty (RTSA), and distinguished preoperative patient characteristics correlated with their occurrence. Researchers distinguished 1,479 patients undergoing either primary or revision RTSA between 2013-2018 with a minimum 3-month follow-up applying two institutional registries from different regions of the United States. They conducted multivariable logistic regression to distinguish preoperative patient factors associated with the development of ASFs. The data exhibited that in female patients with suboptimal bone health, the non-negligible percentage of ASFs that occur after RTSA is correlated with the diagnoses of rotator cuff dysfunction and chronic fracture sequelae. This information can be applied to counsel individuals and set expectations about potential setbacks in recovery.
