    Notes: Intraindividual length differences up to 1.2 cm in femora, up to 1.0 cm in tibiae and up to 1.4 cm in whole leg length can be regarded as physiological. Length differences in childhood are frequently compensated for by functional adaptation in the chain of adjacent limbs. In adults, however, that adaptability is diminished and correction osteotomy after post-traumatic shortening may therefore be indicated more generously dependent on local and general criteria of operability. A conscientious analysis of bone geometry by clinical means, radiology and computed tomography is mandatory for the indication and planning of any correction osteotomy. Intraindividual leg length differences of more than 4 cm are preferentially treated by continuous callus distraction techniques. Shortening by less than 4 cm, however, is suitable for a one-stage stepwise prolongation osteotomy in the metaphysis of the femur, i.e. in the subtrochanteric or supracondylar region. These osteotomies are than stabilized by long condylar plates; the bony defects are filled up by auto- or allogenous corticospongeous bone. Simple modifications of the stepwise prolongation osteotomy permit additional corrections of torsional deviations up to 20° or of axial deviations in the frontal or sagittal plane up to 5°. The results of 24 one-stage stepwise prolongation osteotomies of the subtrochanteric and supracondylar femur after congenital or post-traumatic shortening are presented as well as the reason and respective therapies for three important complications.

    Description / Table of Contents: Zusammenfassung. Grundsätzlich sind 4 posttraumatische Zustände des proximalen Femur durch Osteotomien beeinflußbar: Rezidivierende Hüftluxationen und -subluxationen, Femurkopfnekrosen, Pseudarthrosen, Deformitäten. Unter Berücksichtigung der individuellen Situation ist dabei in allen Fällen ein diagnostisches, indikatorisches und therapeutisches Raster zu respektieren, das sich im wesentlichen aus folgenden Schritten aufbaut: 1. Analyse des Problems unter Berücksichtigung von Vorgeschichte, Klinik und bildgebender Diagnostik; 2. Indikation zur Osteotomie; 3. zeichnerische Planung; 4. Operationstechnik. Spezifische diagnostische, indikatorische und operationstechnische Besonderheiten dieser posttraumatischen Veränderungen werden beschrieben. Auf Korrekturen von Deformitäten in der Frontal- und Sagittalebene, von Translationen, von Längen- und Torsionsdifferenzen wird speziell eingegangen. Der klinischen, übersichtsradiographischen und computertomographischen/sonographischen Analyse der Beingeometrie kommt hierbei ein zentraler Stellenwert zu. Bei der Vielfalt und Komplexität posttraumatischer Zustände des proximalen Femur kann nur eine perfekte maßgeschneiderte Lösung die Antwort auf ein ganz individuelles Problem sein.
    Notes: Summary. Basically, four post-traumatic conditions of the proximal femur can be improved by corrective osteotomies: recurring luxations and subluxations of the hip joint; necrosis of the femoral head; non-unions; deformities. Dependent on the individual situation, the following procedure can be recommended, including diagnosis of deformities and indication and therapy of corrective osteotomies: analysis of the problem from the viewpoint of history, clinical findings and imaging techniques; indication for corrective osteotomy; graphic planning; operation technique. Particularities of post-traumatic conditions with regard to diagnosis, indication and surgical technique are indicated. Only with perfectly tailored concepts can we respond to the individual situation of an individual patient and reflect the variety and complexity of post-traumatic conditions of the proximal femur.
