[Treatment of fresh and old ruptures of the extensor tendons (author's transl)].

Knowledge of topographical anatomy and physiological interplay of several structures is considered essential for regaining the normal function of the extensor apparatus of the finger after an acute or an old injury. For better comprehension of the extensor apparatus and because of its anatomical and functional complexity, two types of structural systems are described, namely, the tendinous and the retinacular system. Aetiological aspects and the pathophysiological mechanisms of deformities such as the "swan-neck deformity, boutonnière deformity and mallet finger" are also described and possibilities of surgical treatment are discussed.

[On the pharmacokinetics of tiaprofenic acid and its possible interactions with acetylsalicylic acid and aluminum hydroxide (author's transl)].

To clarify the question whether pharmacokinetic properties of tiaprofenic acid (presumable trade name Surgam) can be changed by simultaneous application of aluminum hydroxide or acetylsalicylic acid (ASA) a randomized study of 7 healthy volunteers was carried out. The results show that the bioavailability as well as the pharmacokinetic profile of orally administered tiaprofenic acid is not changed by the mentioned compounds.
