Pathologically it pre-sents an interstitial neuritis in the limbs, also a certain degree of degenera-tion in the posterior columns of the cord. Etiology.—The disease is of an hereditary character. Several membersof the same family are frequently affected. Men suffer more than is a disease of the second half of childhood. In one case reported byme (Jour. Nerv. and Merit. Dis., 1903) the disease developed after a pro-longed exposure to cold. Treatment.—Massage and electricity, orthopedic appliances andtenotomy, are all the means we have at our Fig. 109.—Primary NeuriticAtrophy. MUSCULAR ATROPHIES 327 IV. Arthritic Muscular Atrophy.—It accompanies acute and chronicinflammations of the joints. It affects the muscles in the immediatevicinity of the joints and rarely extends to the entire limb in the acuteand subacute forms of rheumatism. In chronic rheumatism the atrophyextends to the muscles lying at a distance from the diseased joint. In thefirst case there may be only one special muscle affected or else the groupof muscles surrounding the joint. In the second case the atrophy becomesdiffused and involves the entire limb. Generally speaking the degree ofatrophy is in proportion with the duration of the arthritis and ankylosisof the joint. When several joints are involved, the generalized muscularatrophy may give the impression of Aran-Duchennes differential diagnosis will show that the electrical reactions show onlya quantitative
