Arms without wrists

The human hand can be flexed at the wrist, extended and even abducted or adducted while the forearm can also be twisted in supination or pronation giving the illusion of the wrist twisting.

All of these movements are necessary for all basic human functions.

But what if the there was not such thing as a wrist? what if the hand would be directly attached to the forearm.

Would things like writing as we know it be possible, if not then what other method of writing would humans have invented? And would there be any advantages to not having wrist or there would be only downsides to not having wrists?

why would such a thing come to pass? how did that limb accomplish its original function of perambulation without a hinge for flexion, assuming that ceature was a quadriped, as all amphibian-derived land animals on earth

Said humans or creatures have an exoskeleton that doesn't allow movements at the wrist, there's no actual wrist.
