[Osteosynthesis of subtrochanteric femoral fractures with the dynamic condyle screw]. / Die Osteosynthese subtrochanterer Femurfrakturen mit der Dynamischen Kondylenschraube.

The dynamic condyle screw was originally designed for osteosynthesis of distal femoral fractures. Because of more favourable biomechanical facilities compared with the condyle plate we have been used the implant since 1987. This investigation is based on 40 patients with pertrochanteric, subtrochanteric as well as proximal diaphyseal fractures. The majority of the patients were mobilized early and reached full weight bearing latest after 3 months according to the fracture type. The most severe complications appeared with subtrochanteric fractures with lack of medial cortical support. There was a broken plate in 2 cases and a secondary spongiosa plastic was necessary in 3 cases to ensure bony consolidation. As the point of this investigation we will see a wider indication for primary spongiosa plastic and early secondary spongiosa plastic.
