Clinical follow-up revealed that in addition to pain reduction there was an improvement in the shoulder function as assessed according to the Constant and Murley scores. Evaluation of the DASH questionnaire and the Sf-36 health questionnaire clearly showed the improved function of the arm as well as the positive effect on the patients' general state of health.
