Blueberry bush with one large trunk

I have several blueberry bushes and I largely ignored pruning them for several years. The time finally arrived and I pruned several of them last year. All but one had numerous canes of varying ages. However, one plant has a single large "trunk", bigger than my wrist. A foot or so up it splits into several branches. I pruned off a large, problematic branch last year and was rewarded with new growth in the vicinity of the cut, but not new canes coming up from the ground. How would I go about pruning this...tree?
