How does the Ponseti method work?

What causes club feet?
Clubfoot is mainly idiopathic, which means that the cause is unknown. Genetic factors are believed to play a major role, and some specific gene changes have been associated with it, but this is not yet well understood. It appears to be passed down through families. It is not caused by the fetus’ position in the uterus.
How long does Ponseti method last?
Casting by an orthopedic surgeon who has been trained in the Ponseti method usually starts when a baby is a week or two old, and lasts for 5 to 7 weeks. When the foot is in its final, correct position, the baby is fitted with a brace.

How does a Pirani vacuum gauge work?
The Pirani gauge measures the vacuum pressure dependent thermal conductivity from the heated wire to the surrounding gas. The heat loss is a function of the gas pressure and at low pressure the low gas density and long mean free path between gas molecules provides a low thermal conductivity.
