Anterior Pelvic Reduction and Fixation Using a Subcutaneous Internal Fixator

Acute traumatic pelvic instability mandates reduction and mechanical stabilization to maximize the chance of a good functional outcome. Posterior pelvic fixation is frequently inadequate to stabilize the pelvic ring in isolation. Fixation augmentation with anterior pelvic ring implants can take several forms, including plates, medullary screws, or external fixation. Based on a multitude of patient and injury factors, external fixation may be the definitive anterior pelvic implant of choice. However, many drawbacks exist with this treatment, most notably the high infection rates of the transcutaneous pins, impaired patient mobilization, and suboptimal mechanical properties. We present a technique of a subcutaneous anterior pelvic fixator as an alternative method of anterior pelvic ring reduction and stabilization that avoids many of the drawbacks of traditional anterior pelvic external fixation.
