Why do some injuries never heal, or take so many months/years?

Considering the fact that a female body can form a fully functioning body inside its womb in 9 months, shouldn’t it be much easier to, suppose, fix a leg injury? Why can it not do the same to repair itself?

The female body is designed to nurture and sustain a fetus through childbirth. There are hormones, muscles, ligaments, and other parts that work together toward this end.

The leg, however, is not designed to be broken by an outside force and repair itself. A displaced fracture, for example, cannot realign the broken ends to heal; without intervention, the displacement will remain, poorly healing the limb and likely causing disfigurement and loss of function.

Minor cuts and scrapes do heal themselves, generally with no intervention.
