This is the more ordinary course, but the signs show great variety in different cases. 1. The disease may remain limited to the palm, not giving rise to flexion of the finger; this is especially frequent in women. 2. Any or all of the fingers may be attacked, and the rigid bands may implicate also the thenar and hypothenar eminences. 3. Either or both inter-phalangeal joints may become flexed, while the metacarpo-phalangeal joint remains free. 4. The palmar cord may remain single and central, or it may send off a lateral branch on either or both sides in the inter-digital web, and so implicate two or three fingers. 5. A central band, after reaching the root of the finger, may bifurcate, sending a branch to either side of the digit; this, in my experience, is the least common variety. 6. The cord, instead of running along the central axis of the finger, may pass towards the inter-digital cleft and then divide, giving branches to two digits; a band of this kind would be in dangerous relation to the digital vessels and nerves in the event of operation by excision. (Fig. 1.) The statistics as to fingers affected in my series of cases correspond closely to those already published by Adams, Keen, and others. They are as follows: Thumb, four times; index finger, three times; middle finger, twenty-two times; ring finger, thirty-nine times; little finger, twenty-eight times (these numbers include the purely palmar bands where they were placed over the metacarpo-phalangeal articulation, but had not yet led to contraction of the digit; traumatic cases are excluded). The most common association where more than one digit was affected was that of the ring and little fingers; when a single finger was attacked, it was most frequently the fourth. The flexion involved in almost equal proportions the metacarpo-phalangeal joint alone, and this together with the first inter-phalangeal joint. In four cases the first inter-phalangeal joint was contracted, while the metacarpo-phalangeal articulation was free, and in one case the distal joint alone was flexed, although the band extended from the palm. In only two cases were all the fingers implicated. The condition was bilateral in twenty-four cases out of thirty-nine, right-handed in ten, and left-handed in five. Thus the right hand was attacked thirty-four times, and the left twenty-nine times. Of the twenty-four bilateral cases, nine were worse in the right hand, six in the left; in the rest the severity differed little on the two sides. Nearly one-third were unsymmetrical as to the fingers attacked. In eight patients, six of whom were women, the band was purely palmar, and did not cause any contraction of the fingers.
