Finally, the limitationof motion cannot be lessened by inclining the head toward themuscle that seems to be most contracted, for the reflex sj^asmof Potts disease limits motion in every direction. As a rule,the diagnosis is easily made, but in cases complicated by sup-puration of the cervical glands it is sometimes impossible to Fig. Posterior torticollis.

Disease of the cervical spine, other than tuberculous, is com-paratively rare, and resembles in its symptoms Potts diseaserather than torticollis. Arthritis of the suboccipital articula-tions may be a manifestation of rheumatism; it may follow in-fectious disease, or it may occur as an isolated infection. It is 682 OBTHOPEDIC SUBGERY. of sudden onset, and it resembles acute spastic torticollis, ex-cept that all the surrounding muscles are affected rather thana particular group; in fact, but for the history it could not bedistinguished from tuberculous disease of this region. Although the diagnosis of torticollis is simple, it is not alwayseasy to determine the muscle or muscles involved in the con-traction. The effect of unilateral contraction of the differentmuscles is as follows: The sternomastoid inclines the head toward the contrac
