PLANTER LATERAL DISLOCATION OF THE MEDIAL CUNEIFORM - A CASE-REPORT

This case report describes an isolated plantar lateral dislocation, of the medial cuneiform. We were able to find only one other similar cas e reported in the literature. That case had a delayed diagnosis of 5 m onths and with an associated an avulsion fracture of the second metata rsal base.(4) Dines et al.(3) reported an isolated dorsomedial disloca tion at the medial cuneonavicular joint. An irreducible dorsomedial di slocation with the anterior tibialis tendon being trapped between the medial cuneiform and the navicular has been reported.(2) A distar and lateral dislocation of the medial cuneiform was reported in associatio n with displacement of the second to fourth metatarsal and medial frac tures of the navicular and cuneiform.(1) The current report differs fr om previous cases. There was not an associated fracture; the direction of the dislocation was unique and could be reduced closed.
