- Discussion: 
- pretendinous bands arise from the palmar fascia as strips of tissue which
extend toward the bases of the digits;
- the neurovascular bundle will lie on either side of the pre-tendinous bands;
- at a point distal to the distal palmar crease, the pretendinous bands partially
attach to the skin;
- in Dupuytren's contracture, the pre-tendinous bands will thicken and contract,
forming the
pre-tendinous cords;
- at a point just distal to the
superficial transverse palmar ligament (which is
just proximal to the metacarpal heads), the pretendinous cord bifurcates
to form the
spiral bands;
