Do we need trials of agents alleged to improve healing of plantar ulcers?

The assumptions underlying trials of agents claiming to heal plantar ulcers 'faster' and 'better' are shown to be fallacious and it is pointed out that in most cases these ulcers fail to heal for lack of attention and not for want of a specific topical agent. Clinical trials in this area are difficult and are not worth the trouble as they do not add to our knowledge about these ulcers or their management in the clinic or in the field.
