Background: Fractures of the acetabulum are rare injuries. The indication for surgical stabilization depends on the grade of instability and dislocation. Exact knowledge of the different possible surgical approaches is essential for the planning of the surgical treatment. Both, knowledge of anatomical structures and possible risks of the different approaches, are important.
Methods: Over a period of 15 years, we analyzed all patients with acetabular fractures, treated in our Level I Trauma Center with special interest in surgical and approach-related complications. Based on our complication rates, we describe the used different surgical approaches and the accessible anatomical structures respectively. Finally, we focus on strategies to reduce the risk of approach-related complications in acetabular surgery.
Results: Between January 2003 and December 2017, 523 patients with an acetabular fracture were treated in our Tertiary Referral Hospital. Of these, 101 patients had at least one complication, resulting in an overall complication rate of 19.3%. 296 patients underwent surgical treatment of the acetabular fracture, while 227 patients were treated non-operatively. Surgically treated patients had a significantly higher complication rate of 21.2% (63/296) compared to conservatively treated patients with a complication rate of 16.7% (38/227). Neurovascular and thromboembolic adverse events were the most often complications.
Conclusions: Patients with acetabular fractures are at a high risk for different kind of complications. The most common risks are neuro-vascular and thromboembolic incidents. The risk of getting a complication is increased in surgically treated patients, therefore both the indication for surgical treatment and the surgical approach should be carried out carefully, including individual patient parameters and fracture types as well as the surgeons expertise.
