    Description / Table of Contents: Résumé L'étude des espaces intercapito-métacarpiens sur 23 sujets frais et conservés soulève la question de l'existence de bourses séreuses à ce niveau, à l'instar des études récentes [1, 4] faites au niveau du pied. Une dissection soigneuse et des études histologiques apparaissent compatibles avec l'une des hypothèses suivantes: la présence soit de bourses séreuses non décrites jusqu'ici dans les ouvrages d'anatomie, soit d'espaces virtuels inter-capito-métacarpiens limités distalement par un cul-de-sac des aponévroses de la main au niveau des 2e, 3e et 4e espaces. Des études histologiques pouvant déterminer de façon plus spécifique la nature de la membrane limitante de ces espaces dans sa partie libre, ainsi que des études pathologiques qui mettraient en évidence les pathologies habituelles des bourses séreuses au niveau de ces espaces, sont nécessaires afin d'affirmer définitivement leur nature. La comparaison entre les espaces inter-capito-métacarpiens et inter-capito-métatarsiens et leurs membranes limitantes a mis en évidence des caractéristiques semblables tant au point de vue anatomique qu'histologique.
    Notes: Summary The study of the spaces between the metacarpal heads on 23 cadavers, raises the question of the existence of bursae at this level. This is in line with recent studies [1, 4] suggesting that such bursae are present at this level in the foot. Careful dissection and histological studies revealed characteristics compatible with both of the following hypotheses: either the existence of bursae not described until now in anatomy text-books, or spaces limited by a cul-de-sac of the aponeuroses of the hand in the 2nd, 3rd and 4th digits. Tissue analyses that could determine more specifically the nature of the limiting membrane of these spaces, as well as pathological studies demonstrating the occurrence of common anomalies of bursae in these spaces, are required in order to conclude definitively the nature of the spaces between the metacarpal heads. The gross anatomical and histological characteristics of the spaces between the metacarpal and metatarsal heads and of their limiting membranes were compared and found to be analogous in our series.

    Notes: Conclusion Nos données sont compatibles avec l'existence de bourses séreuses au niveau de la main et du pied (figs. 8, 9). Cependant, l'absence de descriptions antérieures précises, la difficulté d'individualisation de la paroi, l'aspect translucide et l'extrême fragilité de la paroi libre dans sa partie distale, l'existence d'une structure histologique compatible avec celle d'une membrane de bouse séreuse, mais non-spécifique, et l'absence de liquide dans ces espaces ne permettent pas de conclure de manière définitive et sans équivoque qu'il s'agit de bourses séreuses. Des études histologiques permettant de déterminer de façon plus spécifique la nature de la membrane limitante de ces espaces dans leur partie libre, ainsi que des études pathologiques qui mettraient en évidence les pathologies habituelles des bourses séreuses (inflammation, épaississement de la membrane, présence de liquide en quantité accrue) au niveau de ces espaces, sont nécessaires afin de conclure définitivement sur la nature des espaces inter-capito-métacarpiens et inter-capitométatarsiens.

    Notes: A study of the inter-metacarpo-phalangeal spaces on 20 human bodies was carried out to establish the existence of bursae at this level. Recent studies (Bossley and Cairney: J. Bone Joint Surg. [Br.], 62-B:184-187, 1980; Midy et al.: Bull. Assoc. Anat., 70:37-41, 1986) suggest that such bursae are present at this level in the foot.Careful dissection and histologic studies revealed characteristics compatible with both of the following hypotheses: either these are bursae not previously described in anatomy texts, or these are virtual spaces limited by a cul-de-sac of the aponeuroses of the hand in the 2nd, 3rd, and 4th spaces.Tissue analyses that could determine more specifically the nature of the limiting membrane of these spaces, as well as pathologic studies demonstrating the occurrence of common anomalies of bursae in these spaces, are required in order to unequivocally establish the nature of the inter-metacarpo-phalangeal spaces.

    Notes: The purpose of this study was to evaluate the individual variations of the foramen transversarium of the seventh cervical vertebra. This foramen sometimes has the same dimensions as the foramina of the other cervical vertebrae, but it can also be smaller, or absent. In cases where a foramen is present in the seventh cervical vertebra, vascular or nervous structures (or both) can be occasionally observed within the space.Results confirm that the transverse foramina of the seventh cervical vertebra almost always contain vascular and nervous branches, as well as fibrous and adipose tissue.This report concerns the findings of the macroscopic and microscopic studies concerning the contents of the transverse foramina of the seventh cervical vertebra. The study was carried out by the Department of Anatomy of the Faculty of Medicine, Université Laval.
