    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 chronischen Instabilitäten des oberen Sprunggelenks stellt sich die Indikation zum plastischen Bandersatz. Nach Darstellung der anatomischen Verhältnisse werden aus zahlreichen Operationsmethoden 3 beispielhafte Vertreter einer neuen Bandplastik gegenübergestellt. Die mechanischen Verhältnisse werden am Plexiglasfadenmodell demonstriert. In den einleitenden Bemerkungen werden die biomechanischen Grundlagen zur Bandplastik zusammengefasst. Es folgt dann die Demonstration des operativen Vorgehens. Es wird eine längshalbierte Peronaeus-brevis-Sehne in einen u-förmigen Bohrkanal an der distalen Fibula eingezogen. Die Bohrungen werden mit Kirschnerdrähten markiert und mit einem kannelierten Bohrer und einer eigenen Winkelbohrlehre ausgeführt. Die Enden werden am Rande der Insertionsstellen des Lig. talofibulare anterius und calcaneoîibulare fixiert, womit eine anatomische Imitation der natürlichen Bänder gelingt.
    Notes: Summary Chronic instabilities of the upper ankle joint require ligament replacement. The anatomical conditions are described, and three examples from several operation methods are compared with a new technique. The mechanical conditions are demonstrated with a model. The biomechanical elements for ligament replacement are mentioned in the preliminary comments. Then the operative procedure is demonstrated. A peroneus-brevis tendon, cut in the longitudinal direction, is inserted into a U-shaped channel at the distal fibula. The drilling sites are marked by K-wires and carried out with the help of a cannulated drilling device for angles. The ends are fixed to the lip of the insertion points of the anterior talofibula and calcaneofibular ligaments. This procedure makes it possible to simulate the natural ligaments.
