Vitamin D deficiency is associated with adverse medical outcomes following total shoulder arthroplasty

Orthopedic surgeons should recognize vitamin D deficiency as a potential modifiable risk factor for postoperative complications in TSA. The observed association between vitamin D deficiency and increased rates of readmission and periprosthetic fractures suggests that addressing vitamin D levels may be linked to reduced future healthcare utilization. While correcting vitamin D deficiency preoperatively may be associated with a reduction in the risk of medical complications and improvement in patient outcomes following TSA, further research is needed to better understand the nature of these relationships.
