The radio-metacarpal and metacarpo-phalangeal angles are morepronounced and come nearerto a right angle on the side ofthe paralysis than on the soundside. In paralysis of the ulnar, when the thumb isadducted, the metacarpal becomes flexed and thefirst phalanx extended, causing a disappearance ofthe two angles (the lower angle even tends to besometimes hyperextended); on the other hand, theflexion of the second phalanx which always accom-panies this kind of adduction leads to the formationof another angle (Figs. 22 and 24). This pecuHarappearance is explained in cases of paralysis of theadductor poUicis by a supplementary adduction pro- DIAGNOSIS 605 duced by the extensor longus, and which appears toinv
