Movement is good, let him move around. Keeping the movement safe is harder, a broken hip at that age takes a long time to recover from. Are the stairs unsafe? Slippery? Too steep? Insufficient handholds (not enough support, large gaps)? Those things can be fixed. In addition to those fixes: 3M makes an anti-slip tape that you can install at the lip of each step to prevent slips and falls [1]. There is a clear variant available too.
