Percutaneous Fixation of Hypertrophic Nonunion of the Inferior Pubic Ramus: A Report of Two Cases and Surgical Technique

摘要

Symptomatic hypertrophic nonunions of the inferior pubic ramus are amenable to percutaneous screw fixation in patients with suitable osseous anatomy. Preoperative planning, knowledge of bony and surrounding soft-tissue anatomy, and understanding of intraoperative pelvic fluo-roscopy are required for proper screw fixation in the medullary canal of the inferior pubic ramus.In this article, we report 2 cases of adults with symptomatic hypertrophic nonunions of the superior and inferior pubic ramus, treated successfully with percutaneous medullary screw fixation. Percutaneous screw fixation can be used to successfully treat symptomatic hypertrophic nonunion of the inferior ramus and avoid the potential morbidity of a more extensive open surgical procedure.
