Methods
Computerized hospital records were used to identify all patients diagnosed with calcific tendinitis between August 1996 and July 2001 at our institution. Plain radiographs of all cases were reviewed by the senior author. Cases in which radiographic evidence was inconclusive or that had clearly described dystrophic calcification associated with rotator cuff tears were excluded. With full ethical approval (Oxford Regional Ethics Committee Reference No. C01.171), all patients were interviewed in
Study cohort
Computerized hospital records identified 149 patients diagnosed with calcific tendinitis. Of these, 17 (11.4%) were excluded after radiographic review, 5 (3.3%) were lost to follow-up, and 25 (16.8%) declined to participate. The study cohort of 102 patients (125 shoulders) comprised 73 women (71.6%) and 29 men (28.4%) (P = .0024). Overall, the mean age at onset of symptoms was 43.5 years, with a significant difference in mean age at symptom onset between genders (41.6 years in women vs 48.3
Discussion
The reported prevalence of calcific tendinitis in the general population is highly variable, with estimates varying from 2.7% to 22%.2, 14 Such variations directly reflect the difference in study cohorts and radiographic techniques used. At our institution, 149 patients were diagnosed with calcific tendinitis over a 5-year period (with 102 participating in this study). These are patients who are symptomatic and in whom treatment in primary care has failed and, therefore, must represent a small
