Dupuytren’s disease of the radial side of the hand

Dupuytren’s disease with involvement of the radial aspect of the hand is a clinical entity, which affects the thumb, the first web space, and the index finger. It can be primary or secondary. The palmar fascia anatomy and the clinical aspects of radial Dupuytren’s disease are described. The authors propose a new classification, which has the advantage in requiring only a clinical evaluation. One hundred and fifteen patients were examined for Dupuytren’s disease with radial involvement, primary or secondary, in the Hand Surgery Unit of the University of Modena between 1985 and 1994. Eighty-two (68.3%) of them were treated surgically as hand function was compromised by first web retraction. The most commonly used incisions of the first commissure are straight-line with Z-plasties or the Hirschowitz incision; either a zigzag incision or a Bruner incision is made over the thumb or index finger; Z-plasties described by Iselin are reserved for patients with severe contraction of the index finger. Results were assessed by improvement coefficient, calculated as the ratio of the difference between preoperative and postoperative scores to postoperative scores. Generally, Dupuytren’s disease with radial prevalence is not aggressive and progresses slowly and may be exclusively radial or associated with ulnar disease. In other patients, as the disease progresses, loss of function becomes apparent owing to retraction in adduction of the first commissure and flexion contracture of the thumb or index finger.
