skonys Shoulder Dystocia low key played a part one of the most deadly conflicts in history. Kaiser Wilhelm II was born breech and suffered SD which resulted in a brachial plexus injured which left his arm crippled. In pics he's shown hiding his arm or having it propped on a sword hilt or cane as to make it's small length not apparent but if you're looking for it it's pretty obvious. He always blamed the British Dr who delivered him. His father had throat cancer and was sent, against Wilhelms desires, to doctors in the UK where he died. In April 1889 he stated in fury "An English doctor killed m father, and an English doctor crippled my arm – which is the fault of my mother" (who was English). This sentiment continued up until a lil war broke our in 1914 +3

tinydoc I thought that was technically a problem with the fetus and wasnt considered an obstetric complication. +3

shieldmaiden Because shoulder dystocia is the obstetric complication, it describes the event of the baby getting stuck in the mother's pelvic bone and regressing a bit into the canal. As a consequence, both baby and mother can suffer complications like Erb's palsy for the neonate and post-partum bleeding for mom. +1
