Complications after osteosynthetic treatment of acetabular fractures

The early work of Judet and Letournel in the 1970s and 1980s led to a paradigm shift in the treatment of acetabular fractures. The previously purely conservative treatment was replaced more and more by open surgical approaches. The complex, three-dimensional bony anatomy and the periacetabular soft tissue with a close topographic relationship to intrapelvic and extrapelvic neurovascular and visceral structures implicate an increased rate as well as a high risk for intraoperative and postoperative complications. Simultaneously, anatomical reconstruction with a gap step-off less than 1-2 mm is required. Fractures of the acetabulum are comparatively rare and only few trauma centers have the capability and the infrastructure to treat acetabular fractures. Therefore, the aim of this review was to illustrate the possible intraoperative and postoperative complications of osteosynthetic treatment of acetabular fractures as well as to identify possible strategies for treatment and prevention.
