Complex acetabular fractures are due to high-energy trauma in most cases. The operative management of these types of fractures is often difficult and technically challenging. Almost all of these types of fractures are treated through extensile approaches, and a variety of them have been described. Some of these approaches are associated with complications such as infection, heterotopic ossification, and increased blood loss in addition to increased operative time. This retrospective study was performed at an academic Level I trauma center. From January 2013 to March 2019, 21 patients with complex acetabular fractures were treated with open reduction and internal fixation through a single anterior modified Stoppa approach. The average operative time was 98.80 minutes (range, 60-180 minutes), the average follow-up time was 40 months (range, 24-72 months), and the average Harris Hip Score (HHS) was 87.85 (range, 75-100). At the latest follow-up, 12 (57.1%) patients had an excellent HHS, 8 (38.1%) patients had a good HHS, and 1 (4.8%) patient had a fair HHS. Complex acetabular fractures can be effectively managed by a modified Stoppa approach without the need for extensile or combined approaches. [Orthopedics. 2021;44(3):e353-e358.].
