Different crashes.
The American DC-10 that crashed in Chicago was the result of fractured engine mount bolts. The engine was hung with a forklift (maintenance malpractice), and that damaged the mounting bolts, which failed during takeoff, resulting in the loss of an engine, hydraulic failure, and airframe damage, including loss of slats, from the engine impacting the wing.
The crew had no chance.
The United DC-10 (United 232) had a no.2 (tail) engine failure that damaged the tail and took out a hydraulic junction, resulting in the loss of all hydraulics, all flight controls.
The crew had no chance.
And yet, in one of the finest moments in aviation, Al Haynes, the Captain, aided by several, including Denny Fitch, another United Captain, managed to fly it to Sioux City, Iowa put it down on the runway there.

I've never heard of "hydraulic fuses" - and while they sound good, they wouldn't have helped the American DC-10, which lost slat control, or the United DC-10, which had the hydraulics fail in the rudder. If you were to "fuse" a hydraulic system, to close off parts of it, the rudder would be among the top priority parts of the hydraulic system, and would continue to receive fluid...and bleed out anyway...
