You are describing the "other" treatment, called a 1st ray cutout. This serves to plantarflex the 1st metatarsal/ray to increase dorsal excursion of the hallux over the joint. This works if your hallux rigidus/limitus is from a 1st met elevatus (which you likely do, hence your lack of relief with the Morton's extension) or possibly a compensated foerfoot varus. If you simply have a degenerative joint, then anything that "increases" motion will make it worse. You found a solution, but this is why internet research doesn't always work ;-)
