Dupuytren’s Spiral Band
Frequently Dupuytren’s disease affects the palmar and digital fascia in such a way that the palmar cord, natatory cord and retro-vascular cord thicken and tighten which wraps around the proper digital nerve tenting them up towards the skin making it vulnerable to injury if this anatomic situation is not recognized and/or looked for.
Here you can clearly see how the spiral band is wrapped around the digital nerve.
Another view demonstrating the spiral cord coursing below and around the digital nerve on the radial side of the little finger.
Close up of same: the nerve is seen running obliquely across the prominent thickened, diseased palmar digital spiral band.
