The Lambda Cord: An Anatomic Configuration of Radial-Sided Dupuytren Disease

The thumb and first webspace are involved in a relatively low proportion of cases of Dupuytren disease of the hand (3%–28%). Given the rarity, there has been a paucity of literature regarding anatomic cord configurations and the surgical technique for the management of such radial-sided diseases. There are unique anatomic considerations in the thumb that warrant understanding prior to safe surgical exploration. A case of an anatomic variant of Dupuytren disease involving the thumb and first webspace treated with a webspace skin–sparing partial fasciectomy is described. The current literature regarding surgical management of Dupuytren disease affecting the thumb and first webspace is also briefly presented.
