Comparative Study Clinical Trial Controlled Clinical Trial[Calcaneal cyst: a classical simple bone cyst?].
In the calcaneus differentiation between a solitary cyst and intraosseus lipoma is difficult. Radiologists frequently diagnose an intraosseus lipoma, whereas histology shows the classical signs of a solitary bone cyst. We present 12 cases of a solitary cyst of the calcaneus. ⋯ The histologically confirmed calcaneal cysts showed the radiological signs that are supposed to be typical for an intraosseous lipoma. It cannot be decided whether the histologically diagnosed calcaneal lipomas described by others can be interpreted as fatty degeneration of a calcaneal cyst, or whether fatty areas of the bone marrow have given a wrong impression. Since the literature only describes single isolated cases of a pathological fracture of the calcaneal cyst or lipoma, asymptomatic patients should be treated non-operatively.

Comparative Study[Current treatment modalities for cartilage defects at the knee--results of a nation-wide survey of surgical trauma and orthopaedic clinics in Germany].
A local cartilage defect at the knee is mostly followed by arthritis after a period of time. Up to now there are no options to adequately regenerate hyaline cartilage in vivo. Hence, the present strategies try to create a repair tissue with hyaline-like characteristics or to repair defects by transplanting autologous osteochondral cylinders. The objective of this study was to collect data about the current treatment of local cartilage defects of the knee in Germany. ⋯ There are still discrepancies about the therapy for local cartilage defects of the knee. Our survey illustrates the present status of cartilage repair strategies in Germany.

Comparative Study Clinical Trial Controlled Clinical Trial[Effectiveness of interscalene plexus block for open subacromion decompression].
The aim of this study was to assess the influence of interscalene brachial plexus blocks on the functional outcome, subjective pain appraisal and patient satisfaction after open shoulder surgery. These results were compared with patients treated by conventional analgesic measures. ⋯ By implementing ISB sufficient analgesia in the early postoperative period after open shoulder surgery is attained, allowing for early physiotherapy. This positively influences convalescence and the outcome of the surgical procedure. Furthermore, patients are visibly more satisfied with the postoperative pain management.
