A general procedure is introduced allowing for the complete, infinite twistdecomposition of non-local vector operators in QCD off the light-cone. Themethod is applied to the operators $\bar\psi(x) \gamma_\mu \psi(-x)$ and$\bar\psi(x) \sigma_{\mu\nu} x^\nu \psi(-x)$ as well as to their matrixelements thereby determining all power (resp. target mass) corrections beingrelevant for the related distribution amplitudes.
