[Model of intramedullary compression-osteosynthesis procedure for the humerus].
A method of osteosynthesis is being tested for its effectiveness by means of physican and experimental study and animal research. This could make it possible to stabilize fractures of the humerus diaphysis safely with pressure produced intramedullary on the interfragmentary, that is to say through "Kompressions-Bündelnagelung" (compression bundle nailing). Rating tests on skelleted animal bones have shown stability on quasi natural fractures surpassing the exercise load called for the upper arm. This procedure, however, does not prove rating stability by sole means of staying osteosynthesis with only one pair of nails on diagonal (sawed through) fractures of tibia diaphysis. Rating stability is gained however--even with unrelenting use--through "Kompressions-Bündelnagelung", that is an additional filling in the medulla ossium with a bundle of nails, the fracture having been braced already with the first pair of nails. To use this technique routinely a further simplification of process is necessary much like the one solving the distal guying. Also a reposition instrument is needed which would anable simple nailing. Such a repositor is now being tested at our clinics.
