Not illustrated. 1847 edition. Excerpt: ...state the articular surface of the radius is the lower. The extent of this descent of the ulna measures, with a certain degree of accuracy, the ascent of the radius upon the external condyle. The relative descent of the ulna, or rather ascent of the carpal extremity of the radius, changes the relation of the lunar and cuneiform bones, as regards the direction of their articular surfaces and the fibro-cartilage of the inferior radioulnar joint; and has, in the instance before me, induced, by the altered direction of the pressure and friction, the partial removal of the articular cartilage from the lunar and cuneiform bones, and a marked alteration in the shape and direction of a part of the articular surface of the lunar bone. There is also a considerable aperture through the fibro-cartilage of the radio-ulnar joint. (Vide Plate II. fig. 2.) These deviations from the normal position in the upper and lower extremities of the radius, and the consequent new relation of the ulna and carpal bones, give the explanation of the deformity observable in these cases about the wrist-joint. Knowing that the dislocation of the radius forwards and upwards sometimes baffles the best efforts of the most experienced surgeon, it seemed important to ascertain, if possible, the causes which interfere with the return of the head of the radius into the smaller sigmoid cavity of the ulna. After all the muscles had been taken away from the arm, I endeavoured, by traction at the hand, to draw the head of the radius below the level of the external condyle, but could not succeed; and the chief impediments to my success were my inability to overcome the tension of that small portion of the inter-osseous ligament (which is elastic) placed at the posterior aspect of the arm, more
