Introduction/Purpose:
Charcot Neuroarthropathy can be a challenging condition for the foot and ankle surgeon. Prior studies have reported Vitamin D deficiency to be associated with several lower extremity complications. However, the relationship between vitamin D deficiency and Charcot is not well defined. Therefore, the purpose of this study was to determine if patients with Charcot were more likely to be vitamin D deficient than patients with diabetes alone.
Methods:
A large online database from 2011-2021 was retrospectively queried using CTP and ICD codes. Patients were separated into two groups. Group A consisted of patients with diabetes and Charcot Neuroarthropathy. Group B consisted of patients with only diabetes. Statistical analysis was then run to determine if there was an association between Vitamin D deficiency in patients with Charcot compared to patients with diabetes alone. Demographics including age, sex, and race were also recorded.
Results:
From 2011-2021, a total of 5,428,806 were identified. Group A consisted of 13,519 patients with a mean age of 59 +- 11.6 years. Of these patients, 60% were male (8,064), 40% were female (5,455), 72% were white (9,725), 14% were Black or African American (1,913), 1% were Asian (89), 13% were unknown (1,730), <1% were American Indian (49), and <1% were Native Hawaiian (13). Group B consisted of 5,415,287 patients with a mean age of 59.6 +- 15.4. Of these patients, 50% were male (2,693,118), 50% were female (2,720,313), <1% were unknown (1,856), 59% were white (3,214,4058), 19% were black or African American (995,514), 3% were Asian (139,732), 19% were unknown (1,035,894), <1% were American Indian (20,681), and <1% were Native Hawaiian (13). Patients with Charcot were more likely to have Vitamin D deficiency than diabetic patients alone (OR: 1.687; 95% CI: 1.616, 1.761).
Conclusion:
In our cohort, patients with Charcot Neuroarthropathy were more likely to be Vitamin D deficient than patients with diabetes alone. Given that Vitamin D deficiency has been found to be associated with lower extremity complications, further investigation is warranted.
