1. There is a dispute about whether a person whose foot was amputated may go out with his peg foot/leg on Shabbos.
2. There is a dispute about a sandal used by people who sell plaster.
3. The Mishnah says that if a peg leg/foot has a place inside in which to put cloth, it can become Tamei.
4. A toy stroller can become Tamei through Medras.
5. Pregnant women, or even women who think they are pregnant, may go out on Shabbos with a Tekumah stone.

1. Rebbi Meir: It is permitted, because it is like his shoe. Rebbi Yosi: It is not permitted, because it is not an adornment but rather something that he is carrying.
2. Some opinions maintain that it can become Tamei through Medras, a woman may use it for Chalitzah, and one may go out with it on Shabbos. Others disagree.
3. Abaye: It can become Tamei through Tum'as Mes, but not Medras. Rava: It can become Tamei through Tum'as Medras as well.
4. This is because it has the status of a Kli. In contrast, a walking stick does not become Tamei at all, since it is not considered a Kli.
5. This was a stone they used to wear in order to prevent miscarriages. Rebbi Meir says that they are allowed to go out even with something that was merely weighed against an Even Tekumah.
