    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 Biodegradierbare Implantate finden zunehmend Einsatz in Unfallchirurgie und Orthopädie. Die Anzahl der erhältlichen Implantate und der dabei eingesetzten verschiedenen Polymere nimmt ständig zu, wobei die Biokompatibilität problematisch bleibt. Diese wird von einer Vielzahl verschiedener Faktoren beeinflußt. Lokale Fremdkörperreaktionen können bei der Verwendung biodegradierbarer Implantate auftreten und müssen klinisch dokumentiert werden. Um eine Vergleichsmöglichkeit verschiedener Implantate zu ermöglichen, ist ein standardisiertes Instrument zur Klassifizierung solcher Fremdkörperreaktionen erforderlich. Basierend auf unseren klinischen und experimentellen Erfahrungen wurde ein Klassifikationssystem entwickelt, das eine systematische Dokumentation gewährleistet. Hierzu werden Fremdkörperreaktionen in Osteolysen (O-0 bis O-4), extraartikuläre (EA-0 bis EA-4) und intraartikuläre (IA-0 bis IA-4) Weichteilreaktionen unterteilt.
    Notes: Summary Biodegradable implants are increasingly used in orthopedic and trauma surgery. Many different implants consisting of different biodegradable polymers are currently available. Different factors contribute to the biocompatibility of these implants, and local foreign-body reactions remain a matter of concern. Therefore, it is mandatory to document and compare the tissue reactions caused by various biodegradable implants in experimental or clinical studies. We have developed a standardized system of classification based on our previous experimental and clinical observations. Foreign-body reactions are differentiated into osteolyses (O-0 to O-4), extra-articular (EA-0 to EA-4) and intra-articular (IA-0 to IA-4) soft-tissue reactions.
