[New techniques for bone synthesis on the humerus]

Fractures of the upper arm near the shoulder are common. A consensus on treatment only occurs for simple, un-dislocated fractures and with the complete destruction of the concha in elderly people. For most of the 2-4 component fractures, there exist a variety of, in part contradictory, recommendations in the literature. The most diverse statements mirror the conflict between the best anatomical solution and the practically most stable position with the least possible additional damage of the surrounding structures through surgery. Whether the implants with the most stable angle using the latest generation of plates will lead to an improvement in the results is at present a matter under clinical study. The indications are clearer for the shaft. The development of the latest plates and intramedullary implants provides a surgical improvement, and implant specific complications (e.g., pin movement) will be reduced with further development. Whether there are also advantages for the patient remain to be seen.
