Association of Vitamin D Deficiency With Adverse Postoperative Outcomes Following Hallux Valgus Correction

Background: Hallux valgus (HV) is a common forefoot deformity treated surgically. Vitamin D is essential for bone and soft tissue health, but its role in postoperative outcomes after HV is unclear. This study evaluated whether low preoperative vitamin D is associated with increased complications. Methods: Adults undergoing HV correction were analyzed retrospectively using the TriNetX Research Network. Patients were categorized as vitamin D deficient (≤20 ng/mL), subsufficient (≤30 ng/mL), or sufficient (≥30 ng/mL). Secondary analyses examined outcomes by surgical setting (inpatient vs ambulatory) and procedure type among subsufficient patients. Propensity score matching controlled for demographics and comorbidities. Ninety-day outcomes included wound complications, health care visits, opioid use, and thromboembolic events. Significance was set at P
