==Introduction== Symphysiotomy was advocated in 1597 by Severin Pineau after his description of a diastasis of the pubis on a hanged pregnant woman.<ref>Dumont M: La longue et laborieuse naissance de la symphyséotomie ou de Séverin Pineau à Jean-René Sigault. J Gynecol Obstet Biol Reprod 1989;18:11-21</ref> Thus symphysiotomies became a routine surgical procedure for women experiencing an obstructed labour.{{Citation needed|date=January 2020|reason=where is the evidence that this was a routine procedure}} They became less frequent in the late 20th century after the risk of maternal death from caesarean section decreased (due to improvement in techniques, hygiene, and clinical practice).<ref>{{Cite journal |last1=Bergström |first1=S. |last2=Lublin |first2=H. |last3=Molin |first3=A. |date=1994 |title=Value of symphysiotomy in obstructed labour management and follow-up of 31 cases |journal=Gynecologic and Obstetric Investigation |volume=38 |issue=1 |pages=31–35 |doi=10.1159/000292441 |issn=0378-7346 |pmid=7959323}}</ref>

==Procedure== thumb|right|270px|Patient in a symphysiotomy hammock after surgery, 1907 Symphysiotomy results in a temporary increase in pelvic diameter (up to {{convert|2|cm}}) by surgically dividing the ligaments of the symphysis under local anaesthesia.

The procedure carries the risks of urethral and bladder injury, fistulas,<ref name=":0" /> infection, pain, and long-term walking difficulty.<ref name="multiple" /> Symphysiotomy should, therefore, be carried out only when there is no safe alternative.<ref name="multiple">{{Cite book |url=http://www.who.int/reproductive-health/impac/Procedures/Symphysiotomy_P53_P56.html |title=Managing complications in pregnancy and childbirth: a guide for midwives and doctors |date=2003 |publisher=WHO, RHR Department of Reproductive Health and Research |isbn=978-92-4-154587-7 |editor-last=Mathai |editor-first=Matthews |edition=1st |series=Integrated management of pregnancy and childbirth |location=Geneva |archive-url=https://web.archive.org/web/20020809152505/http://www.who.int/reproductive-health/impac/Procedures/Symphysiotomy_P53_P56.html |archive-date=2002-08-09}}</ref> It is advised that this procedure should not be repeated due to the risk of gait problems and continual pain.<ref name="multiple" /> Abduction of the thighs more than 45 degrees from the midline may cause tearing of the urethra and bladder.
