Re: Symphysiotomy for Shoulder Dystocia

I have never performed a symphysiotomy or Zavanelli (and hope I never am in a situation that desperate), but I trained many years ago with a resident who had performed many in Africa as an alternate for CSection. She described the procedure slightly differently. After a small vertical incision above the symphysis, she takes many rapid scalpel strokes shaving off a very small cartilage each time. The scalpel strokes are taken from the most superficial portion just under the skin, not from the top (cephlad) of the pubis. The pubis separates before the scalpel goes through the symphysis, thus avoiding injury to the urethra.

My questions are:

1. While I am terrified of a Zavanelli (what generalist has any experience with this life raft with the sinking Titanic?), I know very little about long term complications of a smphysiotomy on gait, etc. I know that the pelvis is quite unstable for several months, but how many have long term damage.

2. A symphysiotomy probably not an accepted procedure (in the US anyway), whereas a is. To how much risk is the Obstetrician subjecting himself if he were to perform a symphysiotomy?

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
