Hi,
my Mango has been growing at a lean (like the leaning Tower of Piza) for a while, I've been kinda neglectful on getting it repotted...
Today I went out and saw about a 3 ft branch had snapped off the main stem wondering if I can graft it back on or possibly just root it.
I've never done any grafting, though I know I should have practiced....
Any ideas?
I'd prefer if if I could root it. Of course, it had been starting to flower, too.

Here's a photo of the broken part

Mango cuttings are quie easy to root.
Mangoes are a little trickier to graft than citruses.

Just my two cents here. The plant looked really thin up to the nice new top growth. It may never have gotten strong enough to support the continued new growth up there. I think the plant will recover nicely and send out a lot of new growth from that break...probably just as much in as short a time as you would achieve by grafting a portion back on. Mangos except pruning quite well. I believe the results will be a much healthier plant in the long run.

Joe??? Throughout the world, mango cuttings are considered extraordinarily difficult or impossible to root.

Hmmm... Not based on my experiences from people who do them, but then again, most of them are tissue culture experts. The most common propagation method that I know of mangoes is through marcotting or air-layering. The plants that are easily propagated by marcotting are not that hard to root. You will have to use proper hormones and conditions.

I will post picture of a very simple rooting inexpensive setup that I am using all the time. Am currently rooting blueberries, pomegranates, figs, loquats and others. Unfortunately, no mangoes to root for me yet. I would simply air layer that one.

But I do believe you when you said it is hard to root, so I would carefully consider what others have been doing when they said it is hard to root. Maybe I could be wrong with my observations as I don't do that often, especially when full grown mangoes die out on me every time it freezes and lost motivation of trying to grow them in our zone.

Funny, if i saw a picture of thet tree beforehand, I would have told you to cut it right where it broke...an inch or so above a leaf axil on youngish bark! Your mango seems to have taken matters into its own hands..roots I mean....now finish the job, and cut it clean to prevent disease...
Mangos grow flowers on terminal ends of growing branches. They do need juvenile pruning unless you want to pick fruit at 50-60 foot hight. cut any shoot 18" past the last side branch to one inch above a leaf axil for compact managable growth is my advice....

it would be fun to try a few grafting techniques with the branch...cleft, veneer to name a few, but time is not on your side.. the branches are not viable for grafting for that long...that being said, everything mentioned by others as far as technique seems correct.

I missed the part about rooting the cuttings....
You can root cuttings...it is not easy...the purpose for doing so would be to then graft new growth from the cuttting onto rootstock. So it is kind of an intermediate step if you wish. Rooted cuttings themselves will not grow a taproot, and probably no anchor roots either. therefore, crop load will have to be managed, staking required, and wind will be a constant threat...

However, if this is a prized/rare/one off variety, and you like to do things from scratch, root it, start a seedling, and at some point in the future, take a cutting from the rooted plant and graft it to the seedling...Seems like a lot of work to me though....

Here's my typical simple rooting setup:
