Theposterior border of the astragalus lay in the groove between the anteriorand posterior superior articular surfaces of the calcaneum, and its pos-terior lip had been broken off and remained in its normal relations withthe calcaneum. There was no fracture of either malleolus. The dorsalispedis artery and the extensor tendons lay to the inner side of the headof the astragalus; the peroneal tendons had been displaced from theirgroove and separated half an inch from the fibula. In other cases thedisplacement has been greater and the skin has been broken on theouter side of the foot; in one of Malgaignes the head of the astragalus Fig. Subastragaloid dislocation inward. was almost in contact with the fifth metatarsal bone; in one of Leten-neur^s it corresponded to the outer border of the foot and projectedentirely through a wound in the skin, and the calcaneum had been com-pletely displaced from its inferior articular surface. In one of my ownthe external malleolus protruded through and was tightly grasped bya rent in the skin ; evidently perforation had occurred while the footwas in extreme inversion, and I was obliged to lengthen the openingdownward for an incli in order to reduce.
