. Anatomy, descriptive and applied. Anatomy. TH1<J FOOT 249 ward. It occupies the centre of the front row of the tarsus, between the middle cuneiform internally, the cuboid externally, the scaphoid behind, and the third metatarsal in front. It is distinguished from the internal cuneiform bone by its more regular wedge-like shape and by the absence of the kidney-shaped articular surface; from the middle cuneiform, by the absence of the L-shaped facet, and by the two articular facets which are present on both its inner and outer surfaces. It has six surfaces for examination. The anterior surface, triangular in form, articulates with the third metatarsal bone. The posterior surface articulates with the most external facet of the scaphoid, and is rough below for the attachment of ligamentous fibres. The internal surface presents two articular facets, separated by a rough depression; the anterior one, sometimes divided into two, articulates with the outer side of the base of the second metatarsal bone; the posterior one skirts the posterior border and articu- lates with the middle cuneiform; the rough depression between the two gives attachment to an interosseous ligament. The external surface also presents two articular facets, separated by a rough nonarticular surface; the anterior facet, situated at the superior angle of the bone, is small, and articulates with the inner side of the base of the fourth metatarsal; the posterior and larger one articulates with the cuboid; the rough, nonarticular surface serves for the attachment of For scaphoid For tniddle-cuneiforin.
