Fig. 10. View of the variable arches of proximal interphalangeal joints during the maximum metacarpophalangeal and proximal interphalangeal flexion with maximum distal interphalangeal extention movements. (A) Asymmetrical arches of proximal interphalangeal joint on the right and left sides. (B) On the right hand the 2nd, 3rd, and 4th arches represent the upper level while the arch of the little finger is found lower, on the left side the 2nd and the 3rd arches are at the same level and at the top while the 4th and the 5th are at the same level but lower (shematic view). (C) Asymmetrical arches of proximal interphalangeal joint on the right and left sides. (D) On the right hand the arch of the 3rd interphalangeal joint is located at the top, while the arch of the little finger is found at the lower, on the left hand although the arch of the 3rd interphalangeal joint is located at the top, the arches of 4th and 5th are lower (shematic view). (E) Symmetrical arches of proximal interphalangeal joint on the right and left sides. (F) Both on the right and the left hands the arch of the 2nd interphalangeal joint is located at the top while the arches of the 3rd and 4th are lower.
