1. A prosthetic wrist comprising:
a first piece couplable to a limb socket wearable on a remnant limb of a user;
a second piece couplable to a terminal unit;
one of the first piece and the second piece comprising a ball and another one of the first piece and the second piece comprising a wrist socket;
the wrist socket being removably couplable to the ball and selectively operable between:
an unlocked state where the ball is rotatable relative to the wrist socket in a plurality of different directions to permit flexion or extension of the terminal unit relative to the limb socket; and
a locked state where the ball is fixed relative to the wrist socket by a clamping force applied to the ball with the wrist socket to maintain a position of the terminal unit relative to the limb socket,
the wrist socket comprising a first wrist socket portion, a second wrist socket portion, a hinge that rotatably couples the first wrist socket portion to the second wrist socket portion, and a latch that is operable with an opposite limb of the user to apply the clamping force by decreasing a separation distance between the first wrist socket portion and the second wrist socket portion and release the clamping force by increasing the separation distance between the first wrist socket portion and the second wrist socket portion.
