Objectives:
To describe the injury characteristics, treatment methods, and maternal and fetal perioperative outcomes among pregnant patients with pelvic ring and acetabular fractures.
Design:
Multisite retrospective cohort study.
Setting:
Nine Level I trauma centers.
Patient Selection Criteria:
Adult pregnant patients who presented with pelvic ring or acetabular fractures (AO/OTA 61A-C and/or 62A-C) were included. Patients with trace amounts of human chorionic gonadotropin due to recent miscarriages or deliveries were excluded.
Outcome Measures And Comparisons:
Demographics, concomitant injuries, treatment methods, and perioperative clinical outcomes for both mother and fetus were abstracted and described. Comparisons were made between patients who presented with intrauterine fetal demise (IUFD) and those who did not, as well as between patients treated operatively and nonoperatively.
Results:
Seventy-eight female patients were identified, with 68% having pelvic ring fractures, 22% acetabular fractures, and 10% combined fractures. Median age was 25.4 years (range 18-40 years). The median Injury Severity Score (ISS) was 22. Patients' gravid status was evenly distributed by viability (51.3% viable). One-third of the patients arrived with IUFD (n = 25/78), and those with IUFD had higher ISS (median ISS 30.5 in IUFD group, 16.9 in non-IUFD group). Of the remaining 53 patients, 64% were indicated for surgery, and 36% were treated nonoperatively. Maternal complications occurred in 8% of patients (n = 1/19, 5.3% nonoperative; n = 2/19, 10.5% operative). Among patients who did not arrive with IUFD or deliver their baby before orthopaedic management, fetal complications (premature delivery, miscarriage, and neonatal death) occurred in 28.9% (n = 11/38). Fetal complications were lower in the group treated operatively (n = 4/19, 21.1%) as compared with the nonoperative group (n = 7/19, 36.8%). Miscarriages specifically were similar between these groups (n = 3, 15.8% nonoperative; n = 2, 10.5% operative).
Conclusions:
Fractures of the pelvic ring/acetabulum in pregnant patients frequently result in IUFD at presentation or during the hospital stay. Surgical management added minimal additional risk to the fetus. Miscarriage rates were similar among patients treated surgically and those managed nonoperatively.
Level Of Evidence:
Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
