Parturition and pelvic fracture. Follow-up of 34 obstetric patients with a history of pelvic fracture.

Thirty-four women with a history of pelvic fracture gave birth. Ten had experienced increasing or recurrent pain during the course of their pregnancy. Twenty-seven women gave birth without complications, including 13 patients with displaced pelvis. In only one patient was cesarean section carried out on suspicion of disproportion. Cesarean section was carried out in another case because of resymphysiolysis and in one because of other complications to the pregnancy. Two underwent vacuum extraction because of secondary inertia, but subsequently they gave birth by the vaginal route without complications. In connection with pregnancy and birth, 2 patients had resymphysiolysis. They were the only patients of 8 with symphysiolysis who had undergone osteosynthesis, and both had had the material removed before pregnancy. It is concluded that separation of the symphysis in a pelvic fracture is a more serious complication in subsequent parturition than is displacement of the bony birth canal.
