Q. A close relative lost his right arm, from the elbow down, and was able to replace it with a prosthetic electronic arm. We have some important questions. Firstly, since he still has his complete right hand bicep, on which hand should he put on his tefilin?
A. Horav Shlomo Miller’s Shlit’a opinion is that he should don tefilin as he did before the accident, on his left hand. He can put them on with a brocho using his new bionic prosthetic right hand and does not need someone else to do it for him.
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit’a
