Where the proximal phalanx of index finger sits in the skeleton
The proximal phalanx of the index finger is the base segment, which joins the metacarpal. The index finger has three phalanges: proximal, middle and distal. It is the longest of the three phalanges. It meets the rounded head of the metacarpal at the metacarpophalangeal joint and the middle phalanx at the proximal interphalangeal joint.
