How Orthopedic Trauma Affects the Outcome of the Pregnancy and Delivery How does orthopaedic trauma affect the outcome of pregnancy and delivery? We had a large subgroup. This was completed at Parkland Memorial Hospital in Dallas, Texas. We had 990 pregnant women without orthopedic trauma and 65 women with orthopedic trauma, both represent the largest series, the largest numbers in the literature. We directly compared the outcome of these women and women with orthopedic trauma had a 31% increase incidents of having a preterm delivery. In addition, they had a 25% incidence of having a low birth weight infant and the rate of placental abruption and perinatal mortality was also significantly increased in women with orthopedic trauma. And we looked back, we thought, oh it must be the women with pelvic fractures. When we looked at all the injuries, there was a long bone fractures at the lower extremity four. There were 47 people that broke their ankle or their P-line or their tibial plateau which is near the knee. They broke those bones and there were 19 women who broke their wrist or forearm, two people with spine fractures, yet these women with this wide variety of injuries all had a poor outcome whether they had surgery for their fractures or not or whether their injury was -- the severity of the injury did not really affect the outcome. It’s just the stress of a pregnant trauma patient with an orthopedic injury.
