Many different procedures are used for the operative treatment of acute AC joint dislocations type Rockwood III - VI. We discuss the clinical results for an exact anatomical reconstruction of the AC-joint by transosseal acromioclavicular and coracoclavicular FiberWire cerclage. ⋯ This procedure for an exact anatomic AC joint reconstruction shows good objective results with a high Constant and Rowe scores for shoulder function. Postoperative ossifications of the AC joint ligaments are common, but seem to have no influence on the clinical results.

Long-term results after resection of comminuted fractures of the radial head (Mason III and IV) may lead to valgus elbow instability, radius proximalisation and rotatory instability. Radial head replacement has been used to prevent and treat these complications. The aim of this study was to define the value of the bipolar radial head prosthesis of Judet for treating comminuted fractures of the radial head. ⋯ In comminuted fractures of the radial head (Mason III and IV), bipolar radial head replacement with the Judet prosthesis leads subjectively to very good and good and functionally to good and fair results on the medium-term view. Joint stability is achieved and secondary complications like valgus elbow deformity and proximal radial migration are prevented. Patients must be informed about the possibility of temporary nerve lesions, heterotopic ossification causing limitation of motion and the lack of long-term results.
