    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 Da auch heutzutage die Behandlung der Mittelhandbrüche kontrovers diskutiert wird, wurde eine Literaturanalyse durchgeführt, um die unterschiedlichen Therapien, Indikationen und deren Ergebnisse aufzuzeigen. Aus der Literatur vom 1. 1. 1984–31. 03. 1996 wurden Daten von 1602 nachuntersuchten Patienten verglichen; 522 operativ versorgte Patienten wurden mit Kirschner (K)-Drähten, Schrauben, Plättchen, Cerclage oder Minifixateur externe behandelt. Die konservativen Ansätze reichen von der Immobilisation bis hin zu unterschiedlichsten frühfunktionellen Methoden mit verschiedensten Hilfsmitteln oder gar ohne jede Fixation des Bruches. Die frühfunktionelle Therapie mit einem Brace kam bei 95 % zu sehr guten und guten Ergebnissen, hatte aber eine Therapieabbruchrate von bis zu 23 % aufgrund von lokalen Druckstellen und Hautnekrosen (3 %). Die teilweise Ruhigstellung mit unterstützendem Handcast, Tape etc. kam bei 94 % zu sehr guten und guten Ergebnissen. Hierbei traten keine Komplikationen auf. Jeweils 85 % sehr gute und gute Resultate erzielten die operativen Verfahren und die Immobilisationsbehandlung. Die Reposition von Mittelhandknochen (MHK)-V-Frakturen hatte nur bei 15 % der Patienten Erfolg. Metarkapalefrakturen mit Dislokationen unter 30 °, einer Verkürzung von weniger als 5 mm, einer Rotationsfehlstellung unter 10 °, keiner Gelenkstufe und ohne relevantes Weichteiltrauma benötigen nach unseren Ergebnissen keine Operation und sollten auch nach den Ergebnissen der Literaturrecherche frühfunktionell behandelt werden. Bei Überschreitung dieser Grenzen ist eine primäre operative Therapie gerechtfertigt. Die Immobilisation von Mittelhandfrakturen über mehr als 3–4 Wochen ist nicht sinnvoll.
    Notes: Summary As the treatment of metacarpal fractures is today still a controversial subject, we conducted an analysis of the literature in order to present the different therapy guidelines, indications, and their results. The data from the follow-up of 1602 patients was taken from literature which dated from 1 January 1984 to 31 March 1996. A total of 522 patients who underwent surgery received K-wires, screws or external minifixateur. The conservative approaches ranged from immobilization to various methods of mobilization with different aids or without fixation of the fracture. The mobilization in a brace provided good to excellent results in 95 % of the cases; however, the failure rate of therapy was 23 % because of local bruises and skin necrosis (3 %). The mobilization with handcast, tape etc. attained good to excellent results in 94 % of the cases. Here, no complications occurred. Both the immobilization treatment and the surgery provided good to excellent results in 85 % of the cases. The reposition of fractures of the fifth metacarpal was successful in only 15 % of the cases. Fractures with dislocations below 30 °, a shortening of less than 5 mm, no rotational displacement or that below 10 °, no articular incongruency, and no relevant soft tissue trauma do not need surgery according to our results and should be treated with early mobilization as suggested by the survey. Beyond these limits a primary surgical therapy is justified. The immobilization of metacarpal fractures over a period of more than 3–4 weeks is not necessary.
