Shoulder motility was impaired in 137/140 patients. Nearly all patients had taken oral analgesics, 81% had undergone physiotherapy, five patients had been operated on, and six had been irradiated. Radiotherapy was applied using regular anterior-posterior opposing portals and Co-60 gamma rays or 4 MV photons. 89% of the patients received a total dose of 6 Gy (dose/fraction of 1 Gy twice weekly, the others had total doses ranging from 4 to 8 Gy. The patients and the referring doctors were given written questionnaires in order to obtain long-term results. The mean duration of follow-up was 6.9 years [0¨C20 years].During the first follow-up examination at the end of radiotherapy 56% of the patients reported pain relief and improvement of motility. After in median 4.5 months the values were 69 and 89%, after 3.9 years 73% and 73%, respectively. There were virtually no side effects. In the questionnaires, 69% of the patients reported pain relief directly after radiotherapy, 31% up to 12 weeks after radiotherapy. 56% of the patients stated that pain relief had lasted for "years", in further 12% at least for "months".Low-dose radiotherapy for periarthropathy of the shoulder was highly effective and yielded long-lasting improvement of pain and motility without side effects.The application of roentgen rays to the joints has been known since the end of the 19th century and was found to be successful even more than 70 years ago [1,2]. In the following decades, radiotherapy for benign diseases was widely accepted in Germany, Switzerland and Austria, while these techniques were rarely utilized in other West European countries for fear of an elevated frequency of secondary malignancies [3,4]. In general inflammatory or degenerative disorders of the joints or the surrounding tendons are treated with very low total doses o %U http://www.ro-journal.com/content/2/1/34
