G. B., a domestic servant, aged twenty-two, was admitted into St. Thomas’s Hospital in June 1889, with contraction of the third, fourth, and fifth fingers of the right hand at the first inter-phalangeal joints. The patient, a strong, healthy girl, quite free from neurotic tendencies, stated that her little and ring fingers had been contracted from early childhood, and that the condition had increased slowly but progressively to the present time. The middle finger became similarly affected about five months before admission. She had never suffered from pain, and the parts had been free from all sign of inflammation; the deformity, however, caused very great inconvenience in her occupation. Two months before admission an attempt had been made to relieve the flexion of the little finger by subcutaneous section of the fascia, with the result of inducing a traumatic contraction of the metacarpo-phalangeal joint. The family history was negative. On examination the little finger was found to be flexed at an angle of 90° at the first inter-phalangeal joint, and the metacarpo-phalangeal joint was bent at an angle of 120° by cicatricial contraction of the skin and subcutaneous tissue (the result of the operation alluded to). The ring finger was flexed at the first inter-phalangeal joint to about 110°, and the middle finger at the corresponding articulation to about 150°. In the case of the inter-phalangeal joints, the movements in the direction of flexion were quite free and of normal power, but extension was strongly resisted by ligamentous tension at the points named. No increase in the range of movement was gained by flexion of the wrist. A first operation was undertaken for the relief of the cicatricial contraction at the proximal joint of the little finger. The tense integumental band was divided, and after straightening the joint a flap was dissected from the ulnar side of the digit opposite the point of incision and twisted into the gap. (Fig. 4.) The wound united by first intention, and the result was permanent. A week later an operation was performed upon the first inter-phalangeal articulation of the same finger. The lateral ligaments were divided subcutaneously near their proximal attachment, and it was found that the joint could then be straightened by the use of moderate force; but on the discontinuance of the extension the contraction was reproduced by the elastic tension of the flexor, except during flexion of the wrist. The hand was placed upon a splint. The patient, who did not bear restraint well, left the hospital, and has since been lost sight of.
