    Developmental changes in the retrorectal region of the human fetus (1988)

    Notes: Summary A morphological study concerning the development and arrangement of the connective tissue in the retrorectal region was performed by investigating 300–700 μm thick sections through fetal pelves, plastinated with the epoxy resin E 12 and cut with a diamond wire-saw. In 9–20-week old fetuses several developmental processes take place simultaneously in the retrorectal region: In the 9-week old fetus there is a marked incongruity between the curvature of the rectal wall and that of the caudal elements of the vertebral column. However, by the 20th week this incongruity has disappeared and the curvatures of the two structures parallel each other. During the developmental process, the position of the rectum in relation to the caudal parts of the vertebral column is changed. Due to the changing position of the rectum, alterations of the connective tissue are found especially in the precoccygeal portion of the retrorectal region. In the mesenchyme of 9-week old fetuses a differentiation of the retrorectal space into compartments can already be seen. With increasing age of the fetuses, three different compartments can be distinguished between the rectum and the ventral surface of the sacrum and coccyx. By the 20th-week of human development fasciae can be identified within the connective tissue. In comparison to the various fasciae that have been described in the retrorectal region of the adult, only the pelvic parietal fascia is to be found in 20-week old fetuses. Fibres of this fascia traverse the retrorectal space and divide it into a presacral and a precoccygeal portion.

    Notes: Summary A topographical study concerning the autonomic nerves in the pelvis of human fetuses was performed by investigating 300–600 μm thick sections through fetal pelves, impregnated with the epoxy resin E 12 and cut with a diamond wire-saw. In addition the inferior hypogastric plexus of a 26-week old male fetus was dissected by lateral approach. In 21–29-week old fetuses the pelvic autonomic nerves are relatively thick. Thus the nerves stand out well against surrounding structures and their topographical relationships can exactly be determined. The inferior hypogastric plexus of 21–29-week old fetuses is situated on a curved line between the rectum and the ventrally adjacent structure. It constitutes a rectangular plate, which cannot be subdivided into individual plexuses for the different pelvic organs. The fetal plexus is heavily ganglionated. Large ganglia, forming the so-called ganglion of “Frankenhaeuser”, are found in the female as well as in the male fetus. In the fetal pelvis the connective tissue compartments are still clearly arranged, because adipose tissue is not yet abundant. The greater part of the inferior hypogastric plexus is situated exactly at the border between a dense visceral tissue medially and a loose parietal tissue laterally. The plexus does not share a common connective tissue cover with the pelvic blood vessels. In fetuses the inferior hypogastric plexus lies in close vicinity to serveral organs, but the pelvic floor is the only region where the nerves can hardly be separated from the surrounding structures.

    Gibt es einen knöchernen Strecksehnenab- oder -ausriß? Plastinationshistologische Untersuchungen zur Insertion der Streckaponeurose und deren Bedeutung für die operative Therapie (1999)

    Description / Table of Contents: Zusammenfassung. Mit Hilfe von dicken transparenten Schnittpräparaten aus Langfingern wurde nachgewiesen, daß die Fasern der Streckaponeurose auch distal des beim „knöchernen Strecksehnenausriß“ vorhandenen Basisfragmentes inserieren. Daraus ergibt sich die handchirurgische Konsequenz, das Fragment nicht mehr wie bisher von dorsal freizulegen. Durch einen mediolateralen Zugang erfolgt die intraarticuläre Darstellung zur Reposition des Fragmentes. Die distal des Fragmentes inserierenden Fasern werden dadurch geschont, die Kontinuität der Streckaponeurose wird nicht unterbrochen. Ein weiterer Vorteil der intraarticulären offenen Reposition besteht darin, das Fragment stufenlos unter Sicht fixieren zu können.
    Notes: Summary. With the help of thick, transparent finger cross sections, it was shown that fibers of the extensor aponeurosis insert distal to the avulsed fragment of the distal phalanx. The consequence for hand surgery is not to expose the fragment through a dorsal incision, but through a mid-lateral one. In this way, the distant parts of the aponeurosis distal to the fracture remain intact, and there is no break in the continuation of the dorsal extension plate.

    Tomographical anatomy of the pelvis, visceral pelvic connective tissue, and its compartments (1995)

    Notes: The sectional anatomy of the pelvic connective tissue was studied in plastinated sections of fetal and adult pelves, by computed tomography and by magnetic resonance imaging. The comparative study of the different specimens shows that the pelvic connective tissue consists of three compartments: a presacral compartment, a perirectal compartment, and a paravisceral compartment. The content and the borders of the compartments are described. Furthermore the pelvic fasciae and the pelvic ligaments are studied within the different specimens. A thin pelvic visceral fascia can only be found around the perirectal compartment. In tomographical anatomy the so called supportive ligaments of the uterus are only composed of the round ligaments and the sacrouterine ligaments. © 1995 WiIey-Liss, Inc.
