Dendrobium Lost All Leaves / Keiki

[zomorph]

I have a dendrobium which I have had for over a year now. It has never flowered since I got it and always seemed very healthy.

It grew a new cane last year, but no flowers. This summer it started to grow two new canes but before they were were even two inches they turned brown and died off.

Shortly after it started growing keikis all over the remaining 4-5 canes. There are about 9 keiki's growing at various places all over.

Finally in the past two weeks all of the leave of the main plant have fallen off.

Here is a picture, though not too good of it before it lost its leaves.

Any idea of what might be happening? Is the main plant going to continue to die off now that it lost its leaves?
