We give a parametrization of zero-dimensional ideals in the power series ring k[[x,y]] with a given leading term ideal with respect to local lex ordering in terms of certain canonical Hilbert-Burch matrices. This is an extension to the local setting of the parametrizations of Gröbner cells obtained in the polynomial ring k[x,y] by Conca and Valla for lex ordering and Constantinescu for deglex.
