Composite osteosynthesis

from Wikipedia, the free encyclopedia

In orthopedics and trauma surgery, composite osteosynthesis is a special form of plate osteosynthesis for the treatment of certain bone fractures . The procedure usually combines plate fixation with stabilization with bone cement .

Indications

The main indication is a pathological fracture with a large substance defect caused by a primary bone tumor or osteolytic bone metastases from cancer . Usually the long bones are affected, often the femoral neck, the pertrochanteric region or the area of ​​the humerus head at the shoulder joint. In severe osteoporosis , an extensive debris zone rarely forces stabilization by means of composite osteosynthesis.

method

After the fracture has been repositioned openly , a suitable bridging plate fixation is applied. Depending on the body region, an angle plate , a dynamic hip screw with a long plate or a long angle-stable plate can also be used. The defect area is then filled with bone cement. In this case, the fracture does not heal, the load is borne by the bone cement, which serves as a replacement for the missing bone substance. The result is usually load-stable from the start.
