Background: Smoking is a major cause of tissue hypoxic damage which is one of hypotheses for pathophysiology of calcifying tendinitis in shoulder. The purpose of this study was to assess the association between smoking and various lifestyle factors expected to lead to hypoxic damage with calcifying tendinitis.
Methods: We examined patients with shoulder pain who performed ultrasound on shoulders at the outpatient orthopedic
department of a university hospital from May 2011 to March 2013. The subjects were surveyed using a specific questionnaire for 18 patients who were diagnosed with calcifying tendinitis and 41 control patients who were diagnosed with non-calcifying tendinitis. Logistic regression analysis was used to calculate the odds ratio of smoking and lifestyle factors for calcifying tendinitis.
Results: Mean smoking amount was 13.9 pack-year in the calcifying tendinitis group and 21.2 pack-year in the non- calcifying tendinitis group. Current smokers were prevalent in 38.9% among the calcifying tendinitis group and 17.5% among the noncalcifying tendinitis group, but the difference was not statistically significant. Current smoking was associated with increased risk of calcifying tendinitis (odds ratio [OR], 5.53; 95% confidence interval [CI], 1.33 to 22.94). Being overweight (body mass index≥23 kg/m2) (OR, 3.79; 95%CI, 1.08 to 13.25) and frequent exercise (OR, 4.49; 95%CI, 1.13 to 18.1) were related to an increase of calcifying tendinitis. Coincidence of dominant hand and painful shoulders, exercise using shoulders, and current alcohol intake had no relationship with calcifying tendinitis.
Conclusion: Current smoking and obesity may be risk factors for calcifying tendinitis causing acute shoulder pain.
