The impact of noninfective enteritis and colitis on outcomes following shoulder arthroplasty: a propensity-matched retrospective cohort study of 8,574 patients

Background: Patients with noninfective enteritis and colitis (NIEC), a term including Crohn's disease, ulcerative colitis, and other chronic inflammatory bowel diseases, are more likely to have decreased bone mineral density due to chronic inflammation and impaired vitamin D absorption. Previous studies have assessed acute post-operative complications of patients with NIEC undergoing shoulder arthroplasty (SA). The purpose of this study is to explore the long-term impact of NIEC on SA revision rates and mechanical complications. Methods: values were calculated. Results: = .001). At 3, 5, 7, and 10 years, the NIEC cohort had significantly higher risk of revisions (RR = 1.235, 1.349, 1.386, 1.405) and PJIs (RR = 1.426, 1.488, 1.526, 1.555). Conclusion: Patients with NIEC have a higher long-term risk of revision surgery and PJIs following SA, suggesting a complex association that should be considered.
