_False Dupuytren’s contraction._—There is a form of digital contraction usually classed with that just described, but differing from it in origin and several other respects. It is always due to obvious traumatisms, such as incised or lacerated wounds, involving the palmar or digital fascia. The age at which the lesion begins is governed by the period of injury, and hence the condition is as common in childhood and early adult life as in middle or old age. The seat of initial lesion is single, and the affection is confined to the injured hand, not tending to appear subsequently in other parts of the same hand or in the opposite member, as in most examples of the ordinary form. The contraction progresses rapidly to a certain point, and then ceases to get worse. It rarely becomes so strongly marked as in the worst cases of the true Dupuytren’s disease. The contracted band, starting from the point of injury (which is indicated by an ordinary scar) has seldom the tendon-like form of the well-marked “Dupuytren,” the characteristic puckers in the skin are represented only by ordinary cicatricial adhesions, and the digital extensions are usually in the form of one or two lateral bands following the bifurcation of the digital process of the radiating fascia. Lastly, the effect of operation is different. Subcutaneous division is less efficacious when the skin is extensively implicated in the cicatrix, and the excision of the band or the transplantation of a flap after division of the cicatrix is not followed by the strong tendency to recurrence observable after similar proceedings in the true form. In all the seven cases in my list the nature and traumatic origin of the disease could be recognised without difficulty. A subcutaneous cicatricial contraction of the finger may also result from violent and sudden super-extension of the joint. The lateral bands extending from the radiating fascia are ruptured, and if the finger is not kept straight by mechanical appliances a contraction of the joint is liable to occur. In such cases the resistance to extension is felt to depend upon two tense lateral bands, while the movements of the articulation in the direction of flexion remain strong and normal.
