Although there is a well-defined association between musculoskeletal disorders and environmental, genetic, and lifestyle risk factors, the etiological role of Vitamin D in musculoskeletal diseases is still an area of active research. The objective of this study was to evaluate the correlation between serum Vitamin D levels and the incidence of LE among a population in Eastern India.\n\nMaterials and Methods: A total of 150 subjects, 75 with diagnosed LE and 75 age- and sex-matched controls, were studied cross-sectionally. Serum Vitamin D concentrations were determined and calculated for the possible association with LE prevalence and severity.\n\nResults: A total of 75 cases and 75 controls were analyzed. Both groups were comparable in age and gender. Mean serum Vitamin D levels were significantly lower in cases than controls (15.3 \u00b1 7.2 vs. 28.5 \u00b1 10.1 ng\/mL, P &lt; 0.001), with Vitamin D deficiency more common among cases (70% vs. 22%). Serum Vitamin D level was strongly negatively correlated with LE (Pearson\u2019s r = \u22120.62, P &lt; 0.001). Vitamin D deficiency increased the odds for LE by over threefold (odds ratio 3.2; 95% confidence interval: 1.8\u20135.6). This association remained significant across subgroups, with the highest prevalence observed in those performing repetitive upper-limb activities.\n\nConclusion: The study showed a strong negative correlation between the low serum Vitamin D status and the occurrence of LE, implicating a possible role for Vitamin D in the pathogenesis of this disease. This emphasizes the clinical significance of Vitamin D status monitoring in at-risk subjects for LE development and its role in both preventive and therapeutic treatment.\n\nKeywords: Lateral epicondylitis, Vitamin D, serum Vitamin D levels, elbow pain, musculoskeletal disorders, tennis elbow.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i01.6686","type":"journal-article","created":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T02:44:16Z","timestamp":1768358656000},"page":"303-308","source":"Crossref","is-referenced-by-count":0,"title":["Correlation of Serum Vitamin D Levels and Incidence of Lateral Epicondylitis of the Elbow: An Observational Study in Eastern India"],"prefix":"10.13107","volume":"16","author":[{"name":"Department of Orthopaedics, Institute of Medical Sciences and Sum Hospital, Bhubaneswar, Odisha, India,","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Udit Kumar","family":"Biswal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pooja","family":"Priyadarsini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Biochemistry, Institute of Medical Sciences and Sum Hospital, Bhubaneswar, Odisha, India.","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T02:44:17Z","timestamp":1768358657000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/01\/correlation-of-serum-vitamin-d-levels-and-incidence-of-lateral-epicondylitis-of-the-elbow-an-observational-study-in-eastern-india\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i01.6686","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
