[Experimental animal studies of spring osteosynthesis].
Clinical experiences from spring osteosynthesis suggest that more stability and possibly earlier neogenesis of the bone in the fracture area can be achieved by suitable springs for osteosynthesis. This stronger stability of fixation could be proved in experiments on cadaveric bones. In 13 experiments on dogs the biologic occurrences at spring osteosynthesis were compared to those at inflexible osteosynthesis. Observation was carried out by means of x-ray films, Tc-scintigraphy, and histologic examination; used were the methods of applying an autologous graft and of transverse osteotomy of the femora of the dogs. The question initially asked could not be answered definitely. Basing on the reported experiences, however, an experimental procedure is proposed which might yield results with clinical relevance.
