    Notes: Abstract A knee joint simulator with anatomical reconstruction of the joint surfaces and of the ligamentous structures was built for teaching purposes. With this simulator it is possible to demonstrate the anatomy, physiology and kinematics of knee ligaments, to teach and learn how to conduct ligamentous instability tests and to demonstrate the effect of knee ligament reconstructive surgery.

    Description / Table of Contents: Zusammenfassung Die intraossäre Injektion von physiologischer Kochsalzlösung oder Lokalanaestheticum (Prilocain) hat einen lindernden Einfluß auf die Ruheschmerzen in rheumatischen Schultern. 28 Schultern wurden mit dieser Methode behandelt und gleichzeitig der intraossäre Druck mit einem einfachen Venendruckgerät gemessen. Ein Abfall des Druckes wurde in den meisten Fällen nachgewiesen.
    Notes: Summary Intraosseous injection of physiological saline or local anaesthetic (prilocain) results in a marked relief of rest pain in rheumatoid shoulders. 28 shoulders were treated in this way and the intraosseous pressure of the proximal end of the humerus was measured with simple central venous pressure equipment. The intraosseous pressure tends to decrease after injections.

    Notes: Abstract This paper reports on a scientific workshop to study anterior cruciate ligament (ACL) reconstruction. The aim is to present recommendations for ACL reconstruction methods that will be of use for surgeons. A study of knee anatomy and graft placement concluded that the tibial attachment must be posterior enough to avoid graft impingement against the femur, and methods to attain this were presented. On the femur, poor graft placement leads to excessive changes of the graft attachment site separation distance as the knee flexes, and the worst case corresponds to the attachment being too far anterior. It was agreed that there were typical patterns of graft tension changes as the knee flexes, and that grafts should be tensioned close to full knee extension. A typical tensioning protocol would be 60 N tension applied at 10° of flexion. It was recognised that graft remodelling caused uncontrollable tension changes post-operation. Graft twisting, to recreate the anatomical spiral of ACL fibres seen in the flexed knee, was also discussed.

    Notes: Abstract A case of an anatomical variation of the arterial vessels in the popliteal fossa, leading to a vascular transection during a total knee revision is presented. The authors believe this complication should be considered in all cases of knee revision surgery.

    Notes: Abstract This article develops a two-country, two-sector model with imperfect competition in one sector and asymmetric labor market structures in the sense that trade unions have wage bargaining power in one country whereas the labor market is competitive in the other country. We use a new approach to model product market integration, and it turns out that the unionized country gains from integration in terms of welfare, and, if the initial level of integration is relatively low, experiences an increase in employment and investment.

    Description / Table of Contents: Synthesis and Structure of Adamantyl-Substituted Methyleneaziridines1)The thermolysis of the 1,1-dibromocyclopropanes 3b, c in the presence of primary amines produced the 3,3-disubstituted N-alkyl(2-bromo-2-propen)amines 2b, c. These as well as 2a afforded the 1-alkyl-2-alkylideneaziridines 4 on 1,3-dehydrobromination with sodium amide in liquid ammonia. The isopropylideneaziridine 4b crystallizes monoclinically as a racemate in the space group P21/n with four molecules per cell. The angle between the plane of the three-membered ring and the 1-adamantyl nitrogen bond is 55.4°. Some structural parameters of 4b are discussed.
    Notes: Die Thermolyse der 1,1-Dibromcyclopropane 3b, c in Gegenwart primärer Amine ergab die 3,3-disubstituierten N-Alkyl(2-brom-2-propen)amine 2b, c. Daraus sowie aus 2a wurden die 1-Alkyl-2-alkylidenaziridine 4 durch 1,3-Dehydrobromierung mit Natriumamid in flüssigem Ammoniak erhalten. 4b kristallisiert als Racemat monoklin in der Raumgruppe P21/n mit vier Molekülen pro Elementarzelle. Die Bindung zum Substituenten am Stickstoffatom ist um 55.4° aus der Dreiringebene ausgelenkt. Einige Strukturparameter von 4b werden diskutiert.
