FWIW , I did upright rows for quite some time the last years. The reason i did them was because they supposedly target the lateral deltoids as opposed to typical OHP that targets the anterior deltoids.
Loved them, no problems at all with shoudlers and/or back. Not particularly strong though, doing sets of 10-12 with 40-45kg, so maybe the load was too light to cause damage, weakness saved me. Also, and maybe that made a difference, i was using the EZ bar.
Also great exercise for big shoulders without wrecking them or back, KFs recommendation, seated neutral grip DB OHP.
1c ( n=1 experience and no theory back-up , so not even worth 2 cents
)
