(4) Mobility. TABLE A. Backward. Forward. Outward. Inward. Unrecorded. Total. Extension Backward. Forward. Outward. Inward. Unrecorded. Total. *The precentages in TABLE C. are based on the whole number of luxations in the direction under consideration; thus 100 % of the outward luxations have free pronation because six have this movement free and there are only six outward luxations in all. Stimson32 quotes Krönlein's statement "that the records of Von Langenbeck's polyclinic show 90 congenital dislocations of the hip, 5 of the shoulder, 2 of the head of the radius, and I of the knee." Congenital dislocation of the hip, the commonest of the congenital dislocations, was found by Chaussier once in 23,293 infants born at the Maternité, although Parise, in 332 hip dissections of all the children who died at the Hospital des Enfants Trouvés, found congenital dislocation of the hip three times.34 (2) Congenital Character. The arguments for the congenital character of these dislocations. of the head of the radius are: (1) Discovery of the condition early in infancy, without preceding trauma. (2) The fact of being bilateral, although Bartels35 reports a bilateral dislocation of the head of the radius in a boy, acquired by pushing a |
