Keywords: Elbow, extensor carpi radialis brevis, lateral epicondylitis, pain, vitamin D.


Objectives: This study aims to examine the relationship between low vitamin D levels and lateral epicondylitis (LE).

Patients and methods: Between January 2016 and January 2018, a total of 40 patients (17 males, 23 females; mean age: 38.6±10.7 years; range, 18 to 59 years) diagnosed with LE were included as the study group, while 66 patients (33 males, 33 females; mean age: 33.6±12.5 years; range, 18 to 58 years) who did not have any elbow complaints and met the study criteria were included as the control group. Both groups were compared in terms of vitamin D levels, of which levels of >30 ng/mL were considered normal, levels between 20-30 ng/mL were accepted as vitamin D insufficiency, and levels <20 ng/mL were categorized as vitamin D deficiency.

Results: Vitamin D levels of the LE group were significantly lower than the control group (p<0.001). The mean vitamin D level was 16.47±8.22 (range, 8.32 to 39.55) ng/mL in the LE group, and 23.64±8.4 (range, 11.6 to 49) ng/mL in the control group. While 31 of the patients (77.5%) diagnosed with LE had vitamin D deficiency, four (10%) had vitamin D insufficiency, and five (12.5%) had normal vitamin D levels. In the control group, 29 (43.9%) patients had vitamin D deficiency, 20 (30.3%) had vitamin D insufficiency, and 17 (25.8%) had normal vitamin D levels.

Conclusion: Although the etiology of LE has not been fully understood yet, vitamin D levels were significantly lower in LE patients in our study. This finding supports that low vitamin D may be one of the factors in the etiology of LE.
