This may have been presentfor a long time, increasing in amount at different periods with pain andtenderness. The joints gradually become more immobile, the infiltrationdisappears, and the enlarged ends of the bones become more or less ankylosis develops, and on motion crepitus and grating isfelt on account of the eroded cartilage.

Some-times the wasting is very extreme and gives the hand the appearancethat is seen in pseudo-muscular atrophy. The general symptomsthat attend each affection serve to distinguish them. Rheumatoidarthritis is easy of recognition when the other joints are involved inthe process. Contractions of the hand may often be observed from other causesthan the ones just mentioned. Temporary contractures occur in tetany,in temporary hemiplegia or monoplegia, and in paralysis of the exten-sors. So-called wrist-drop is seen in peripheral neuritis, particularly inthe form due to lead. The hand hangs from the wrist on account ofparalysis of the ex
