Pathologic Pubic Symphysis Diastasis in Pregnant Pelvic Ring Fracture Treated with INFIX: A Case Report

Unstable pelvic ring fractures in pregnancy are an uncommon injury. Successful treatment of these patients with an INFIX device is even less common, with sparse literature to document the patient outcomes. We found no literature documenting the acute management of a pregnant patient with an INFIX device with (1) dynamic changes recorded, such as increasing pubic symphysis diastasis, and (2) restoration of normal symphyseal anatomy after birth and INFIX removal.

Use of a pelvic INFIX during pregnancy allowed functional independence. The construct offered sufficient stability while also allowing for pubic symphysis diastasis. After parturition, she returned to normal function with no injury sequela.
