- Discussion:
- Grayson's &
Cleland's ligament hold skin in position during flexion and extension of the finger;
- Grayson's ligaments are thin and go from tendon sheath to the skin, and to some extent protect
the nervovascular bundle (prevent bow stringing of the N/V bundle during flexion);
- they are frequently dz'ed in Dupuytren's contracture;
- Anatomy:
- extends from volar periosteum and tendon sheath to the lateral digital sheet
as well as the overlying skin;
- origin:
volar aspect of the flexor tendon sheath;
- course:
volar to the neurovascular bundle;
- insertion:
skin
- function:
- holds neurovascular bundle in place, preventing bowstringing when
finger is flexed;
