Winkelstabile Implantate am proximalen Femur

The use of angle stable implants is not innovative because already in the middle of the last century those implants were used effectively giving better operative results to a high rate. The principle of the angle stability is of enormous importance because a proximal femoral fracture includes a life threatening situation often being negatively influenced by strong bending forces, the individual status of osteoporosis and the fact that the injury has taken place at a burden limb. The advantages of angle stable inclined actual dynamic stabilization systems guarantee always partial load stability and to a high rate a full load capacity. The difference to angle stable implants at other regions points out that there are two supplementary systems with and without sliding mechanism and implants with extra- and intramedullary stabilization. The angle stability may be influenced by external effects and factors under regard to the specified fracture classification which influences the indication for a certain implant. Finally the patient's compliance can influence the angle stability decisevely by a second bang or by comorbidity. Reflecting to the past we can differenciate historical, conventional still actual and innovative angle stability.
