[Radial shock wave therapy in calcifying tendinitis of the rotator cuff--a prospective study].

AIM: The aim of the study is to evaluate the influence of radial shock wave therapy (RSWT) on the course of calcifying tendinitis of the rotator cuff. MATERIAL AND METHODS: 35 patients with a mean age of 47.5 years suffering from calcifying tendinitis stage Gaertner 2 with a mean size of 16.6 mm in typical location (true-ap view) for a mean of 28 months were treated by low-energy RSWT three times. The acromio-humeral distance averaged 10.4 mm measured at the true-ap view. All patients were clinically and radiologically followed-up at 4 weeks, 3, 6 and 12 months after the last treatment. RESULTS: The Constant score improved significantly (p < 0.0001) during the first 4 weeks after RSWT from a mean of 68.5 to a mean of 80.5 points and remained approximatively constant at 3, 6 and 12 months follow-up. After 4 weeks 25.7% of the patients had no pain, 54.3% reported about pain relief. In the course of the follow-up a significant improvement of pain was observed: up to 80.8% painless and 19.2% pain relief 12 months after RSWT. Radiologically 4 weeks after RSWT the X-ray examination showed in 17.6% no calcific deposit, in 20.5% a disintegration and in 61.5% no changes of the calcific deposit. At further follow-up we found a complete resorption of the calcific deposit in 75% up to 12 months after RSWT and 25% had no change in calcific deposit. Overall three patients (8.5%) had to undergo surgical treatment 3-7 months after RSWT. CONCLUSION: The low-energy RSWT leads within the first 4 weeks to a significant pain relief and an improvement of shoulder function. In consideration of the long history, the size and the spontaneous resorption rate of the calcific deposit, an inductive effect of RSWT on the resorption of the calcific deposit can be assumed.

[Postoperatively recurring instability of the shoulder--a fault analysis in 46 cases].

AIM: The successful operative stabilization of the shoulder joint is a demanding surgical procedure. The causality of shoulder instability is complex with in some cases multiple lesions in different anatomical structures. The surgeon has to understand the complexity of factors causing instability in order to be therapeutically successful. The aim of the study was to document the intraoperative pathology in revision instability surgery. METHOD: 46 patients with recurrent postoperative instability were included (8 female, 38 male, follow-up > 12 months). After diagnostic arthroscopy an open revision surgery was performed in all cases. RESULTS: In 19 cases (40%) an insufficient surgical procedure was performed (inadequate capsular shift with worn out labral tissue). Selection of an incorrect surgical technique was the reason for revision in 12 patients (25%). Anamnestically 5 patients reported a re-injury, whereas objectively only one patient described an adequate trauma. The most frequent finding was an open rotator interval (persisting Foramen Weitbrecht), which was seen in 22 cases (46%). CONCLUSION: A stable range of motion of the shoulder is achieved by a variety of different factors, which leads in most instances to a combination of pathological changes in case of a dislocated shoulder. To understand the contributing factors of an instable shoulder joint is a necessity to carry out a successful surgical procedure.
