In this talk the collinear twist-3 formalism is reviewed, in particular its application to pQCD analyses of transverse spin observables in single-inclusive high-energy processes. The main ingredients in this formalism are three-parton correlation functions that may provide new information on the inner dynamics of quarks and gluons in the nucleon as well as in fragmentation processes. Elements of next-to-leading order calculations in that formalism are also discussed.
