ABSTRACT
Distal radius fractures are one of the most frequent fractures of the upper extremities. The decision for conservative or surgical treatment is made after appropriate diagnostics using conventional radiographic and usually computed tomography imaging examinations. If the indications for surgical treatment are present, various options for reduction and fixation are available. The spectrum ranges from closed to open procedures up to accompanying arthroscopic support. Appropriate preoperative patient education about the procedure and the planned postinterventional treatment is essential. The goal of treatment is to restore wrist function while maintaining mobility and strength with a low risk of complications. All surgical procedures share the principle of reduction to restore anatomical relationship followed by fixation. Closed procedures include fixation with Kirschner wires and the construction of an external fixator. Volar locking plate osteosynthesis has become established in recent years as the method of choice for the majority of the fractures to be treated. For special fracture patterns and the treatment of accompanying injuries, arthroscopic support can be indicated. There is no uniform consensus on the best choice of procedure. This article discusses the possible procedures including the approaches, fixation techniques and specific follow-up treatment.

Treatment of scaphoid non-unions is still challenging for responsible hand surgeons, especially in cases of avascular proximal pole non-unions or failed prior surgeries. Several surgical procedures treating scaphoid non-unions have been established. These aim to restore correct anatomy to provide stability and adequate blood flow. Treatment options range from avascular to free, vascularized bone grafts. The two most used free vascularized bone grafts derive from the iliac crest and the medial femoral condyle. The vascular anatomy of the medial femoral condyle graft is more constant, the donor site morbidity lower and the healing rate higher in comparison to the iliac crest graft. It is easier to harvest the femoral condyle graft and additionally, it can be harvested as a cortico-cancellous or osteochondral graft. Looking at all advantage, we come to the conclusion that the free vascularized medial femoral condyle graft is our method of choice for the treatment of a avascular proximal pole non-union of the scaphoid.
