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 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.
对23具尸体掌骨头间隙的研究，引发了该水平是否存在滑囊的问题。这与最近的研究一致，这些研究表明足部该水平存在此类滑囊。仔细的解剖和组织学研究揭示了与以下两种假设均相符的特征：要么存在解剖学教科书中迄今未描述的滑囊，要么是由第2、3和4指手部腱膜盲端所限制的间隙。为了最终确定掌骨头间隙的性质，需要进行能够更具体地确定这些间隙限制膜性质的组织分析，以及证明这些间隙中滑囊常见异常情况发生的病理学研究。我们比较了掌骨头和跖骨头间隙及其限制膜的大体解剖和组织学特征，发现它们在我们的研究系列中是相似的。
