  We shortly describe the leading twist formalism for spin and
transverse-momentum dependent fracture functions recently developed and present
results for the production of spinless hadrons in the target fragmentation
region (TFR) of SIDIS. In this case not all fracture functions can be accessed
and only a Sivers-like single spin azimuthal asymmetry shows up at LO
cross-section. Then, we show that the process of double hadron production in
polarized SIDIS -- with one spinless hadron produced in the current
fragmentation region (CFR) and another in the TFR -- would provide access to
all 16 leading twist fracture functions. Some particular cases are presented.
