OBJECTIVE: To evaluate the effectiveness of disodium EDTA administration in the treatment of calcific tendinitis of the shoulder. METHODS: Eighty patients with radiographically verified calcific tendinitis of the shoulder were enrolled between September 2001 and October 2003. Patients were randomly assigned to either a study group (n = 40) or a control group (n = 40). Pain and functional level were evaluated before and after treatment and at 1-year followup. Radiographic modifications in calcifications were evaluated before and after treatment. Disodium EDTA was administered through single needle mesotherapy and 15 minutes of pulsed-mode 1 MHz-ultrasound. RESULTS: The study group displayed improvement in all of the parameters analyzed after treatment and at the 1-year followup. Calcifications disappeared completely in 62.5% of the patients in the study group and partially in 22.5%; calcifications partially disappeared in only 15% of the patients in the control group, and none displayed a complete disappearance. CONCLUSION: Our results suggest that the use of disodium EDTA for the management of calcific tendinitis of the shoulder is safe and effective, leading to a significant reduction in pain, improvement in shoulder function, and disappearance of calcifications after 4 weeks, without adverse effects.
