Behandlungsstrategie und Ergebnisse bei infizierten Knieendoprothesen
Infekte stellen immer noch die am meisten gefurchtete Komplikation bei der Endoprothetik dar. Wegen ihrer fast subkutanen Lage sind Knieendoprothesen hier besonders anfallig [1, 3, 5, 7].
Ein Nadelelektroden-Isolationsverstärker für biomechanische Untersuchungen - An Isolation Amplifier for Biomechanical Investigations with Needle Electrodes
In our laboratory for biomechanics, a new isolation amplifier was developed with which to record the electromyographic activity of muscles inaccessible to surface electrodes, in particular that of the rotator cuff. Our basic premisses were maximum safety for the patient or subject investigated, and optimal signal processing. These were achieved by a triple galvanic separation of the patient/subject from the battery power supply and the signal cables and by careful selection of the electronic components.
Die Röntgendigitalanlage als Instrument zur kinematischen Untersuchung der Schulter — Eine Untersuchung zur Strahlenbelastung - Digital Radiography as a Tool for the Kinematic Analysis of the Shoulder Joint - A Study of Radiation Dose
The radiation exposure during biomechanical investigation of the shoulder joint done with a digital radiography system (Polytron 1000 VR - Siemens) was measured experimentally. Total radiation dose and surface dose were determined by phantom measurements. The radiation exposure per image is about 1/6 to 1/7 of that of a conventional study. The digital radiography system used is thus suitable for kinesiologic studies of large joints in healthy volunteers.
Distribution patterns of neoglycoprotein-binding sites (endogenous lectins) and lectin-reactive glycoconjugates during cartilage and bone formation in human finger.
The distribution of endogenous lectins, visualized by labelled neoglycoproteins, and of defined oligosaccharide structures, reactive with plant lectins, during fetal development of the fingers was analyzed in sections of human 3- to 8-month-old fetal specimens. Chondrogenesis as well as ossification were correlated with characteristic modulations in the expression of both glycoligand-binding molecules and characteristic carbohydrate structures. Occurrence of xylose-specific receptors was judged to be an early sign of cartilage development. Similarly, α-mannosyl residues that had been attached to labelled carrier proteins were strongly bound by the extracellular matrix already during early s…
Osteochondritis dissecans of the lateral tibial condyle. Report of a new case and review of the literature.
Osteochondritis dissecans (OD) of the lateral tibial condyle is a rare condition. A review of the literature revealed only nine cases in seven patients. We report about a new case. It is widely accepted that this form of OD originates from an accessory center of ossification. Our case supports this theory. Although comparative roentgenograms of the left knee, taken because of complaints in the right one, were interpreted to be normal, retrospective analysis clearly revealed the lateral intercondylar eminence of the left knee to have been irregular many years before the onset of symptoms. Association with a classical OD in the contralateral knee is striking in most of the reported cases.
