Stoppa approach has recently been adapted for pelvic surgery as it allows direct intra-pelvic reduction and fixation of the quadrilateral plate and anterior column. We report our early experience, indications and complications with this exposure introduced in 2010 in our tertiary unit. A Retrospective review of all Stoppa approaches in pelvic-acetabular fixations was performed from a prospectively maintained database. Of the 25 patients, mean age 40 years (range 15–76), who underwent pelvic-acetabular fixation using Stoppa approach, 21 patients had mean follow up of 7.3 months (1–48 months). All except 24% of patients had one or more additional systemic injury some requiring additional surgery. There were 6 acetabular fractures, 13 pelvic ring injuries and 6 combined fractures. Mean injury-surgery interval was 9 days (range 3–20). 8 patients had an isolated Stoppa approach whilst the remaining others also had an additional approach. Mean surgical time was 239 minutes. Anatomical reduction was achieved in 96% (24/25) cases. There was 1 minor intra-operative vascular injury, repaired immediately successfully, and no late wound infections, or other visceral complications. One patient reported new onset sensory numbness which resolved after the first review. Two patients reported erectile dysfunction thought to be caused by the initial injury. One patient had asymptomatic plate loosening. None required revision surgery. Despite the obvious learning curve, we found this approach safe and it did not compromise accuracy of reduction in well selected patients, but early surgery within 10–14 days is recommended to aid optimal reduction

Operative approaches to the acetabulum are generally classified into anterior, posterior, extensile or combined approaches. The choice of approach depends upon the fracture pattern and the amount of relative displacement affecting the anterior and posterior bony structures. Occasionally, extensile or combined surgical approaches are indicated for the treatment of complex fracture patterns with extensive involvement of both the anterior and posterior acetabular anatomy. However, it is believed that these approaches may be associated with higher complication rates than more limited surgical approaches. The ilioinguinal approach described by Letournel is routinely employed in the treatment of anterior column, anterior wall, anterior column/posterior hemi- transverse and certain associated both-columns, transverse and T-type fractures. The utility of this approach is sometimes limited by difficulty in visualising, reducing and applying instrumentation to the quadrilateral plate and posterior column components of these fractures. A surgical approach described by Stoppa in 1989—and later extended to acetabular indications by Cole and Bolhofner—can be used, often in combination with the lateral window of the standard ilioinguinal approach, to effectively treat the same range of fractures as an ilioinguinal approach. Access to the quadrilateral plate and certain displaced posterior column fracture lines is enhanced by this approach—possibly eliminating the need for combined or extensile approaches in certain cases. A retrospective study undertaken at our institution demonstrated that anatomic articular reduction was achieved in 14 of 17 complex acetabular fractures treated via a Stoppa approach. All fractures in the study had at least 5 mm of posterior column displacement preoperatively
