The supra-transverse intermetatarsocapital bursa: a description and its relation to painful syndromes of the forefoot

Abstract

Very many painful syndromes of the forefoot remain without a satisfactory explanation; although this region contains quite specific structures, it has suffered from the application of analogies with disorders of the hand. Among these specific components, the presence of the supra-transverse intermetatarsocapital bursa provides an explanation of such clinical entities as the acute syndrome of the second intermetatarsal space and gives fresh impetus to the debate on the etiopathogenesis of Morton's metatarsalgia. On the basis of 25 dissections, the authors studied the region between the metatarsal heads, confirming the presence of these bursae and specifying their site and size and particularly their relations with the common plantar digital nerve at its bifurcation into collateral nerves.
