Abstract
BACKGROUND: Low vitamin D levels are common in patients with foot and ankle disorders. We have previously demonstrated that juveniles diagnosed with osteochondritis dissecans (OCD) have a high prevalence of vitamin D deficiency. Moreover, there is evidence that OCD might be related to vitamin D deficiency in general. However, whether or not hypovitaminosis D is associated with OCD of the talus has yet to be elucidated. METHODS: The aim of this study was to determine serum vitamin D levels [25(OH)D] of patients diagnosed with traumatic and idiopathic OCD of the talus. The vitamin D status of patients was measured and correlated to age, sex, season, etiology, laterality, degree of disease, and nicotine abuse. Moreover, parathyroid hormone and serum calcium levels of patients were obtained to assess for severe vitamin D deficiency and secondary hyperparathyroidism. Between January 2015 and December 2017, 65 patients with a mean age of 38.9 years and a total of 68 lesions were identified. RESULTS: In total, 75.4% of patients had low vitamin D levels with a mean overall 25(OH)D level of 24.2 ng/mL. Specifically, 35.4% of patients were vitamin D deficient; another 40% were vitamin D insufficient, and only 24.6% of patients presented with sufficient vitamin D levels. Statistical analysis showed no significant difference comparing vitamin D levels of patients with idiopathic OCD to patients with traumatic OCD. CONCLUSION: We could not find any significant differences in the vitamin D status of patients with OCD of the talus compared with patients with foot and ankle disorders in general. However, we found that vitamin D deficiency was frequent in patients presenting with traumatic and idiopathic OCD of the talus. We believe it might be beneficial to routinely assess and treat the vitamin D status of patients. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
