I am interested in knowing how much force is needed to fracture
the phalanges, metacarpals, carpals,radius, and ulnar bones of
the upper extremity. The reason for this question: machine
guarding practices and the determination of whether a moving load
on a conveyor would generate enough of an impact to fracture any
of the said structures.

I am the staff ergonomist/safety practitioner at a J&J
manufacturing facility. Your response would be very much
