This book is based on contributions presented at the symposion "The Primary Afferent Neuron: A survey oj recent morpho: functional aspects. H held in Zurich on March 24th. 1988 in connection with the 83rd Congregation of the German Anatomical SOCiety. Members of the Anatomical Society as well as non-member researchers were invited to join a circle of specialists to discuss the topiC of primary afferents. In addition. some aspects which had not been dealt with at the Symposion because of shortage of time are represented by invited reviews included in this volume. As sCientific research on the primary afferent neuron is so extensive. it is impossible to take inventory of all the present activities on this subject. This book attempts to provide an overview of various aspects of high actuality and. in particular. shows how morphological research contributes to our present -day concepts of the primary afferent neuron. Although fundamental knowledge on morphology and physiology of the spinal ganglion cell seems to be well established. many questions of the past and the present still await conclusive answers. Thus. many question-marks deter mine the conceptual layout of this book (Fig. 1): First. the peripheral sensory field. and. in particular, the peripheral sensory receptors are discussed."

Lange Zeit schien die Behandlung der Calcaneusfraktur abgekoppelt zu sein von den Fortschritten in der operativen Frakturbehandlung. Mit der Einfuhrung der Computertomographie konnte das Fersenbein zwar erstmals vollstandig uberlagerungsfrei abgebildet werden, die seriellen Schnittbilder waren allerding schwierig zu interpretieren. Mit Hilfe von Knochenmodellen, die aus Computertomographie-Daten entwickelt wurden, konnte eine umfassende Analyse, gegliedert nach Gelenkflachenschaden, Gelenkstellung, Deformation und verschiedenen Frakturformen vorgenommen werden. Anhand sehr praziser, naturgetreuer Knochenmodelle konnten die Frakturen praoperativ simuliert und interne Osteosysnthesen vorgeplant werden. Aus der Verknupfung verschiedener Analyseparameter kann ein neue Klassifikation mit frakturformabhangiger Behandlungsempfehlung abgeleitet werden."
