When a spider loses a leg, it usually breaks at a "breakpoint" (a joint that contains muscles that contract to minimize blood loss), so she never bleeds and dies. Even if the leg is amputated before the breakpoint, the spider will amputate her leg, but only after additional blood loss. This is fatal.
Can spiders survive if they lose their legs?
Leg loss is a common phenomenon in spiders, and depending on the species, 5% to 40% of adults can exhibit a defect in at least one leg. There is no possibility of regeneration after molting of adults, and animals must be managed without appendages until death.
Will spiders die if they lose their legs?
If you really had a broken leg, some or all of it would have fallen off. The spider's muscles are clamped to prevent excessive loss of pressure and fluid. Spiders can live without one, two, or even three legs. It can make their lives more difficult, but they will be okay. 2019
What if a spider loses its leg?

Will the spider's legs return?
If a spider is unhappy enough to lose its leg, it can grow a new leg if it has at least one more molt left in its life cycle. For most species, the new leg is thinner and shorter than the original leg. It may require a couple of molts until the regenerated limbs match their original appearance.
