Dupuytren's disease commonly involves all the following structures in the hand EXCEPT
|A||The palmar aponeurosis|
|D||The pretendinous bands|
a. All the choices are involved except Cleland's ligament, which lies dorsal to the digital neurovascular bundle.
b. Grayson's ligament provides the volar cover and is therefore likely to be involved, as are the other volar structures mentioned.
c. Associating Cleland with "ceiling" and Grayson with "ground" helps in remembering the location of these ligaments.
