Interesting...it does look as though it bent under it's own weight, judging by the length and narrow width of the cane. Looks like it's too tall to hold itself up. It's still producing new leaves, though so I would say it should not be too much to worry about. Think about it this way: If it did (and it's 99 percent likely) bend under it's own weight, it would have done the same thing in nature attatched to a tree.
