According to Catholicism, why are there so few miraculous healings of amputees, if any?

**According to Catholicism, why are there so few miraculous healings of amputees, if any?** This question is inspired from another post on this site: [What are Christian apologetics refutations of the objections posited by the site "Why Won't God Heal Amputees?"](https://christianity.stackexchange.com/questions/92780/what-are-christian-apologetics-refutations-of-the-objections-posited-by-the-site) I would like to have a Catholic response to why God does not heal amputees? Perhaps he has, but they are ever so few. Why? Doubt I will get a canonical answer for this, but a well researched response would be greatly appreciated.
