Joints which depend upon muscular support, as the shoulder,may allow of so much deformity by the relaxation of the muscles whichhave lost their tonicity that the articular surfaces widely separate. The LESIONS AND DISEASES OF SPINAL GRAY. 389 skin is inactive, often cold, and sometimes dry and scaly, but the atrophicconditions so usual in neuritis are practically absent and bedsores arealmost unknown. The lower extremities are affected about three times as frequently asthe upper, and the left leg twice as often as the right. A crossed form,in which the upper extremity on one side is involved with the oppositelower limb, is not rare ; but involvement of both limbs on the same sideis extremely uncommon. In the lower extremity the extensors seem moresusceptible than the flexors ; hence drop-foot, with talipes equinus, flexedknee, and flexed thigh are common.
