    Notes: Abstract An anatomic study of the lateral extraosseous and intraosseous arterial supply of the calcaneus and the lateral soft tissue was carried out on 10 fresh lower adult cadaver legs using different anatomic and radiologic procedures (plastination, modified Spalteholz clearing technique, digital subtraction and rotational angiography and computed tomographic angiography). Consistent patterns of extraosseous and intraosseous lateral calcaneal vascular anatomy were demonstrated. The lateral calcaneal artery is a branch of the anterior tibial artery which crosses over the calcaneal tuberosity and forms a large lateral arch with the lateral tarsal artery which is a branch of the dorsalis pedis artery. The intraosseous circulation is supplied laterally by the lateral calcanear artery, medially via the short branches of the lateral plantar artery. Comparing magnet resonance images after fresh calcaneal fractures the lateral calcanear artery may be interrupted by the impacted lateral bulge, by the conventional lateral surgical approach, or by applying a lateral osteosynthesis plate. This may cause avascular bone necrosis. Furthermore the lateral calcanear artery can clinically serve as a vascular pedicle for a local rotational skin flap to cover soft tissue defects of the heel.

    Description / Table of Contents: Résumé L'étude anatomique de la vascularisaiton artérielle extra et intraosseuse du calcanéus et des parties molles a été faite sur 10 jambes fraîches de cadavres d'adultes. Différentes techniques anatomiques et radiologiques ont été utilisées : plastination, diaphanisation (technique de Spaltholtz modifiée), angiographie numérisée par soustraction, angiographie rotationnelle et angiographie par tomographie computérisée. Les aspects habituels de l'anatomie vasculaire de la région latérale du calcanéus ont été décrits : l'ACL est un rameau de l'artère tibiale postérieure ; elle surcroise la tubérosité calcanéenne et constitue une large arcade latérale avec l'artère tarsienne latérale, branche de l'artère dorsale du pied. La moitié de la circulation intraosseuse passe par l'ACL, médialement par des rameaux courts de l'artère plantaire latérale. Lorsqu'on examine les images obtenues en IRM lors de fractures récentes du calcanéus, on constate que l'ACL risque d'être lésée par l'élargissement latéral du calcanéus écrasé. Elle peut l'être aussi lors de l'abord latéral classique de l'os ou lors de l'application d'une plaque d'ostéosynthèse. Le risque en est la nécrose ischémique de l'os. Enfin, l'ACL peut constituer un pédicule vasculaire intéressant pour un lambeau local de rotation, lors de la couverture des pertes de substances cutanées du talon.

    Description / Table of Contents: Zusammenfassung Bei Unterschenkeldefekten 〉4 cm ist eine Spongiosaplastik oder Rippenspananlage zur Überbrückung nicht mehr ausreichend, so daß wir in diesen Fällen seit 1988 eine Kallusdistraktion nach Ilisarov mit externer Fixierung durch Implantate der AO/ASIF durchführen. Bis zum 1. B. 1995 wurden 15 Patienten mit Unterschenkeldefektfrakturen mit der Kallusdistraktion behandelt. Die durchschnittliche Defektgröße betrug 7 cm, so daß über 1 m Röhrenknochen erzeugt werden konnte. Es handelte sich um 11 Männer und 4 Frauen im Durchschnittsalter von 21,3 Jahren. Bei den Defekten war 3mal eine Knochenresektion bei Tumoren erfolgt und 12mal eine zweit- oder drittgradig offene Fraktur vorausgegangen, davon 6mal mit begleitender Osteomyelitis. Im Mittel waren 5,3 Operationen zum Aufbau erforderlich. Die Komplikationsrate betrug 53% bei einer Behandlungszeit von durchschnittlich 1 Jahr. Bei allen abgeschlossenen Behandlungen waren die Endergebnisse exzellent und gut. Eine Amputation konnte in allen Fällen vermieden werden. Kontraindikation bei Anwendung dieses Verfahrens ist eine fehlende Mitarbeit des Patienten. Durch die Kallusdistraktion besteht eine realistische Chance des Extremitätenerhalts bei schwerem Weichteil- und Knochenschaden. Durch die komplette körperliche Reintegrationsmöglichkeit bei erhaltener Extremität kann eine hohe Motivation bei den Patienten erreicht werden.
    Notes: Abstract In open tibial fractures with defects over 4 cm, spongiosaplasty is considered to be insufficient. Since 1988 we have tried to apply Ilisarov's ideas of callus distraction in combination with modern external fixation devices and AO/ASIF implants. By August 1995, 15 patients with severe tibial fractures had been treated. The bone defect averaged 7 cm. Thus, more than 1 m of tubular bone was produced. Eleven male and 4 female patients, averaging 21.3 years in age, were given this treatment. The defect was caused by resection of a malignancy in 3 cases and a second- or third-degree open fracture in 12 cases, accompanied by osteomyelitis in 6 cases. Reconstruction required an average of 5.3 operations. The complication rate was 53%, and the median duration of treatment was about 1 year. The final results were excellent or good. Amputation could be avoided in all instances. This treatment is contra indicated if the patient exhibits a lack of compliance. There is a realistic chance of salvaging the limb in cases of severe soft tissue and bone defects. In terms of economical considerations, this treatment is cost effective. Physical integrity and mobility without aid is the important motivation for these patients.
