Totally agree with Kruger.
Salvage whatever is available. I began growing some juvenile
vanilla orchid plants last year, which were originally growing in spaghnum moss (which the sender of the orchids was using). I repotted them into 5 mm average diameter scoria rocks - in very good drainage pots.
And now the three plants are growing all over the place. Good air-flow around the plant and through the airy-media pot, and nice tropical temperatures make these plants grow fast.
At the moment, I haven't given the 'vine' anything to grow along - so the leaves just grow along the ground right now. A photo of the plants in scoria (taken last year) is shown in this link
HERE.
All I do is just use the watering spray wand to water the scoria media only. Watering every day is just fine. The leaves remain dry.
One recommendation is to not give the bath-room treatment, such as do not take the plant into the bath-room during shower time, and don't mist the leaves - unless air-flow in the growing area is good ...... otherwise it may invite growth of some things - like certain kinds of fungus.
It looks like you still have good sections of plant with at least a root sticking out. Cut away the degraded leaves, and the dead/dying lower potion of the plant (such an inch or so below the root, and pot that section (with the root) into bark or scoria, in a good drainage pot. Keep the media moist, and provide good air-flow around the plant and pot. Don't allow the roots in the pot to become water-logged.
The 'root-like' things along the stem are roots. They're regular roots. That's why you can cut the
vanilla orchid into pieces, and plant any root region into a pot.
