Abstract：Objective To investigate methods and curative outcomes of limited incision approach in treatment of pelvic fractures. Methods The study involved 44 patients suffering from pelvic fractures treated by limited incision from January 2008 to December 2011, including 31 males and 13 females, at age range of 21-70 years (average 38.3 years). According to Tile classification, 25 cases were with type B fractures (11 of type B1 and 14 of type B2), and 19 with type C fractures (14 with type C1-2, four with C1-3, one with type C2). Surgical incision methods included simple Stoppa approach in 10 cases, Stoppa plus partial ilioinguinal approaches in 13, Stoppa approach plus posterior minimally invasive approaches in 13, discontinuous ilioinguinal approach in five, and discontinuous ilioinguinal plus posterior minimally invasive approaches in three. Results The patients with anterior and posterior pelvic ring injury achieved excellent reduction (separation of fracture sites＜4 mm). All patients could walk in full weight bearing during 6-35 months of follow-up (average 17 months). In the meantime, X-ray radiographs indicated bony union in all cases. There was no fracture displacement or implant loosening. Limited incision approach gained advantages of short incision length, short operation time and little intraoperative blood loss in comparison with traditional ilioinguinal approach. Conclusion Limited incision approach has merits of easy operation, small wounds, short operation time, minimal hemorrhage and few complications in treatment of pelvic fractures and thus is a surgery method worthy of clinical use.
