On the contrary, the ilio-femoral portionof the capsular ligament in front having continuity of structurewith the posterior untorn portion from below the cervix, holdsthe dislocated head in its luxated position. In this dislocation,the ilio-femoral portion of the capsular ligament, by its continuitywith the inferior border of the posterior untorn portion, possessesthe potency which Professor Bigelow claims for it in all disloca-tions. Its position and form, in this luxation, are illustrated inFig. 7:. Fig. 7.—Anterior view of pubic luxation, showing continuity of tissue between theilio-femoral and inferior border of posterior half of capsular ligament in pubic dis-location. It is seen by consulting this illustration, and by examining thepreparation from which it is taken, that the influence exerted bythis part of the capsular ligament depends largely, if not entirely,upon its continuity with the inferior border of the posterior un-torn portion. With this continuity, it has pelvic attachment ateach end, while the central portion lies over the cervix and holdsit in its dislocated position. To elude the grasp of this untornportion of the ligament, we have simply to reverse the directionand successive order of the dislocating force. That force pro- 464 Gunn, Reduction of Dislocations.
