#2202: HipFlip

I did some experimental work a long time ago in connection with replacement hip joints.

Today’s invention is an alternative design, based on placing the cup part in the head of the femur and the ball component protruding from the pelvis (as shown on the right).

This might be advantageous for someone whose pelvis was much more frail and in need of reinforcement than their thigh bone, for example.

It also allows more space to insert some kind of spring-and-damper mechanism within the pelvic ball.
